CLASS A CLASS B Digital equipment meant for light industrial use Digital equipment meant for home use Less restrictive emissions requirement: More restrictive emissions requirement: less than 40 dB µV/m at 10 m 30 dB µV/m at 10 m or 100 µV/m (40 dB relative to 1 µV/m) or 300 µV/m These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequen- cies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit- based systems at frequencies above 300 MHz are generally well below background noise levels. The BL2000 single-board computer has been tested and was found to be in conformity with the following applicable immunity and emission standards. The BL2010, BL2020, and BL2030 single-board computers are also CE qualified as they are sub-versions of the BL2000 single- board computer. Boards that are CE-compliant have the CE mark. NOTE: Earlier versions of the BL2000 sold before 2003 that do not have the CE mark are not CE-compliant. Immunity The BL2000 series of single-board computers meets the following EN55024/1998 immu- nity standards.  EN61000-4-3 (Radiated Immunity)  EN61000-4-4 (EFT)  EN61000-4-6 (Conducted Immunity) Additional shielding or filtering may be required for a heavy industrial environment. Emissions The BL2000 series of single-board computers meets the following emission standards using the enhanced-EMI PCB, Part# 175-0224 Rev. A, and the 668-0003 Rev. A Rabbit 2000 microprocessor.  EN55022:1998 Class B  FCC Part 15 Class B Your results may vary, depending on your application, so additional shielding or filtering may be needed to maintain the Class B emission qualification. User’s Manual 5 1.4.1 Design Guidelines Note the following requirements for incorporating the BL2000 series of single-board com- puters into your application to comply with CE requirements. General  The power supply provided with the Tool Kit is for development purposes only. It is the customer’s responsibility to provide a CE-compliant power supply for the end-product application.  When connecting the BL2000 single-board computer to outdoor cables, the customer is responsible for providing CE-approved surge/lighting protection.  Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a metal conduit to assist in maintaining CE compliance and to conform to good cable design practices.  When installing or servicing the BL2000, it is the responsibility of the end-user to use proper ESD precautions to prevent ESD damage to the BL2000. Safety  All inputs and outputs to and from the BL2000 series of single-board computers must not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).  The lithium backup battery circuit on the BL2000 single-board computer has been designed to protect the battery from hazardous conditions such as reverse charging and excessive current flows. Do not disable the safety features of the design. 1.4.2 Interfacing the BL2000 to Other Devices Since the BL2000 series of single-board computers is designed to be connected to other devices, good EMC practices should be followed to ensure compliance. CE compliance is ultimately the responsibility of the integrator. Additional information, tips, and technical assistance are available from your authorized Rabbit distributor, and are also available on our Web site at www.rabbit.com. 6 Wildcat (BL2000) ������ ��� ��� ��� ��� ��� ��� ��� � �� �� ��� ��� ��� ��� ��� ��� ��� �� ��� ��� ���� ��� �� �� ��� !� ��� ������ ��� �����!������������ ������������������ �����������!�����! ��������� ��� ������ ���� ���� 2.

Power Supply Connection 4. Apply power. Plug in the AC adapter. If you are using your own power supply, it must provide 9 V to 40 V DC—voltages outside this range could damage the BL2000. CAUTION: Unplug the power supply while you make or otherwise work with the connections to the headers. This will protect your BL2000 from inadvertent shorts or power spikes. NOTE: The green PWR LED and the red BAD LED on the opposite end of the board should come on, indicating that the BL2000 is now ready to be used. NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in, or by momentarily grounding the board reset input at pin 9 on screw-terminal header J2. User’s Manual 9 � � 2.2 Installing Dynamic C If you have not yet installed Dynamic C version 7.04 (or a later version), do so now by inserting the Dynamic C CD in your PC’s CD-ROM drive. The CD will auto-install unless you have disabled auto-install on your PC. If the CD does not auto-install, click Start > Run from the Windows Start button and browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the installation once you have selected the setup.exe file. The online documentation is installed along with Dynamic C, and an icon for the docu- mentation menu is placed on the workstation’s desktop. Double-click this icon to reach the menu. If the icon is missing, create a new desktop icon that points to default.htm in the docs folder, found in the Dynamic C installation folder. The latest versions of all documents are always available for free, unregistered download from our web sites as well. The Dynamic C User’s Manual provides detailed instructions for the installation of Dynamic C and any future upgrades. NOTE: If you have an earlier version of Dynamic C already installed, the default installation of the later version will be in a different folder, and a separate icon will appear on your desk- top. 10 Wildcat (BL2000) 2.3 Starting Dynamic C Once the BL2000 is connected to your PC and to a power source, start Dynamic C by double-clicking on the Dynamic C icon on your desktop or in your Start menu. Dynamic C defaults to using the serial port on your PC that you specified during installa- tion. If the port setting is correct, Dynamic C should detect the BL2000 and go through a sequence of steps to cold-boot the BL2000 and to compile the BIOS. (Some versions of Dynamic C will not do the initial BIOS compile and load until the first time you compile a program.) If you are using a USB port to connect your computer to the BL2000, choose Options > Project Options and select “Use USB to Serial Converter.” Click OK. If you receive the message No Rabbit Processor Detected, the programming cable may be connected to the wrong COM port, a connection may be faulty, or the target system may not be powered up. First, check both ends of the programming cable to ensure that it is firmly plugged into the PC and the programming port. If there are no faults with the hardware, select a different COM port within Dynamic C. From the Options menu, select Communications. Select another COM port from the list, then click OK. Press to force Dynamic C to recompile the BIOS. If Dynamic C still reports it is unable to locate the target system, repeat the above steps until you locate the active COM port. You should receive a Bios compiled successfully message once this step is completed successfully. If Dynamic C appears to compile the BIOS successfully, but you then receive a communi- cation error message when you compile and load a sample program, it is possible that your PC cannot handle the higher program-loading baud rate. Try changing the maximum download rate to a slower baud rate as follows.  Locate the Serial Options dialog in the Dynamic C Options > Communications menu. Select a slower Max download baud rate. If a program compiles and loads, but then loses target communication before you can begin debugging, it is possible that your PC cannot handle the default debugging baud rate. Try lowering the debugging baud rate as follows.  Locate the Serial Options dialog in the Dynamic C Options > Communications menu. Choose a lower debug baud rate. User’s Manual 11 2.4 PONG.C You are now ready to test your set-up by running a sample program. Find the file PONG.C, which is in the Dynamic C SAMPLES folder. To run the program, open it with the File menu (if it is not still open), compile it using the Compile menu, and then run it by selecting Run in the Run menu. The STDIO window will open and will dis- play a small square bouncing around in a box. This program does not test the serial ports, the I/O, or the TCP/IP part of the board, but does ensure that the board is basically functional. The sample program described in Section 5.3, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board. 2.5 Where Do I Go From Here? NOTE: If you purchased your BL2000 through a distributor or Rabbit partner, contact the distributor or partner first for technical support. If there are any problems at this point:  Use the Dynamic C Help menu to get further assistance with Dynamic C.  Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/ and at www.rabbit.com/forums/.  Use the Technical Support e-mail form at www.rabbit.com/support/. If the sample program ran fine, you are now ready to go on to explore other BL2000 fea- tures and develop your own applications.

The A/D converter inputs can be used as additional digital inputs using the parameters specified for the digIn software function call. The default threshold for channels IN11– IN21 is also set to 2.40 V, but may be changed by adding two lines to your program as dis- cussed for the digIn software function call.

BL2000 Digital Input Protected Range 18 Wildcat (BL2000) ��������������3������ 3.2.2 Digital Outputs The BL2000 has 10 digital outputs, OUT0–OUT9, each of which can either sink or source up to 200 mA, depending on how the outputs are configured. On boards that carry the CE mark, OUT8 and OUT9 are each capable of sinking up to 750 mA. Each output can be configured individually as either a sinking or a sourcing output as shown in Figure 9. The outputs can be pulled as a group to Vcc, +K, or GND through 27 kΩ resis- tors. Tie the outputs high to either Vcc or +K when using the outputs as sinking outputs (via 0 Ω resistors at R32 or R35 respectively), or tie the outputs to GND via R34 when using the outputs as sourcing outputs. +K is an externally supplied voltage of up to 40 V DC, and is used primarily in combination with current sourcing outputs, and must also be connected to an external supply when an inductive load is connected to a sinking output. NOTE: Remove the 27 kΩ resistors (R143–R150) from the output circuits if no pull- up/down is required to avoid leakage between the outputs. These resistors are located on the bottom side of the BL2000 board above the solder points for screw terminal header J9. ��14�1��5 %� %6.�����/���0���� " �77 ��� ���3� �5 $��1��5 %� %6��������5���� �77 ��� " ���3� User’s Manual 19 ������ ��� ��� ��� ��� �����!������������ ������������������ �����������!�����! ��������������� ��� ���� Figure 9.

BL2000 Relay Output Contact Connections The relay is driven by PA0, which is the same Rabbit 2000 parallel port that drives OUT0 and LED DS4. OUT0 therefore works in parallel with the relay output. The relay included on the BL2000 has contacts rated for 1 A @ 30 V DC or 300 mA @ 120 V AC. When using the BL2000 in a CE-certified application, the voltages handled by the relay must not exceed SELV levels (42.4 V AC peak, or 60 V DC). User’s Manual 21 3.4 Serial Communication The BL2000 has one RS-232 serial channel (with RTS/CTS) or two RS-232 (3-wire) channels, one RS-485 serial channel, and one CMOS serial channel. The RS-232 chan- nel(s) are configured with the serMode software function call. Table 2 summarizes the options. Table 2. Serial Communication Configurations Serial Port Mode B C D 0 RS-232, 3-wire RS-232, 3-wire RS-485 1 RS-232, 5-wire CTS/RTS RS-485 All four serial ports operate in an asynchronous mode. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first byte of a message, is also supported. Serial Port A can be operated alternately in the clocked serial mode. In this mode, a clock line synchronously clocks the data in or out. Either of the two communicating devices can supply the clock. The BL2000 series boards typically use all four ports in the asynchronous serial mode. Serial Ports B and C are used for RS-232 communication, and Serial Port D is used for RS-485 communication. The BL2000 uses an 11.0592 MHz crystal, which is doubled to 22.1184 MHz. At this fre- quency, the BL2000 supports standard baud rates up to a maximum of 230,400 bps. 3.4.1 RS-232 The BL2000 RS-232 serial communication is supported by an RS-232 transceiver, U1. U1 provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 2000’s CMOS/TTL signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V. U1 also provides the proper line loading for reliable communication. RS-232 can be used effectively at this baud rate for distances up to 15 m. 3.4.2 RS-485 The BL2000 has one RS-485 serial channel, which is connected to the Rabbit 2000 Serial Port D through U8, an RS-485 transceiver. U8 supports the RS-485 serial communication protocol. The chip’s slew rate limiters provide for a maximum baud rate of 230,400 bps, which allows for a network of up to 300 m (or 1000 ft). The half-duplex communication uses the Rabbit 2000’s PB6 pin to control the transmit enable on the communication line. The BL2000 can be used in an RS-485 multidrop network. Connect the 485+ to 485+ and 485– to 485– using single twisted-pair wires (nonstranded, tinned) as shown in Figure 12. Note that a common ground is recommended. 22 Wildcat (BL2000) ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� �� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� �� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� �� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� �� �� �� �� �� �� �� �� �� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� �� ���� ���� �� ��� �� ��� �� ����� ��! �� ��� �� �� ��� �� ����� ��! �� ��� �� �� ��� �� �� ��! �� ��� �� �� �� �� ��� �� �� �� ��� �� �� �� ��� �� �� �� �! �� �! �� �! �� �� �� �� �� �� �� �� �! �� �! �� �! ���� �� ���� ��� �� ��� �� �� ��� �� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ���� ���� ���� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��! ��� ��! ��! ���� ������ ���� ������ ���� ������ ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ���� ���� ���� ��� ��� � ��� ��� � ��� ��� � ��! ��� ��! ��� ��! ��� �� �� �� �� �� �� �� �� �� ��� ��� ��� �(*:2,�(’7*55’2,’, ��" ��� &" �� �� �" ! >����� ��" ��� � ��� � ��� � ���; � ���� �$ ��" ��� Figure 12.

Note that there are two standards for numbering the pins on this connector—the convention used here, and numbering in reverse to that shown. Regardless of the numbering convention followed, the pin positions relative to the spring tab position (located at the bottom of the RJ-45 jack in Figure 14) are always absolute, and the RJ-45 connector will work properly with off-the-shelf Ethernet cables. ��<����� &+ � � �@���A�=� �@���A�=; �@���A�=� �@���A�=; $&8’9����� $&8’9�&��2 Figure 14.

Isolation Resistor R1 The factory default is for the 0 Ω resistor “jumper” at R1 to be installed. In high-noise environments, it may be useful to ground the transformer/connector assembly directly through the chassis ground. This will be especially helpful to minimize ESD and/or EMI problems. Once you have removed the 0 Ω resistor “jumper,” R1, use a ring lug to attach the BL2000 to the chassis ground, thereby grounding the transformer/connector assembly. A convenient position for the ring lug has been provided at the top-left mounting screw hole near the RJ-45 jack as shown in Figure 16. ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� �� �� �’5*6’��� ��� ��� ��� ���� ��� ��� �� ��� �� �� �! �� �� �,,�/*+,’(�+:-�&* 7*22’7&�-(*:2, ��� ��� ��� ��� 41(’�&*�70%//1/ ���� ��� ��� ��� ��! ���� ���� ��� ��! �� �� �� ��� ��� �� �� ��� � �� Figure 16. Recommended Location for Ring Lug 3.4.4 Programming Port The BL2000 has a 10-pin programming header labeled J5. The programming port uses the Rabbit 2000’s Serial Port A for communication. Dynamic C uses the programming port to download and debug programs. The programming port is also used for the following operations.  Cold-boot the Rabbit 2000 after a reset.  Remotely download and debug a program over an Ethernet connection using the RabbitLink EG2110.  Fast copy designated portions of flash memory from one Rabbit-based board (the master) to another (the slave) using the Rabbit Cloning Board. User’s Manual 25 Alternate Uses of the Serial Programming Port All three clocked Serial Port A signals are available as  a synchronous serial port  an asynchronous serial port, with the clock line usable as a general CMOS input The serial programming port may also be used as a serial port via the DIAG connector on the serial programming cable. In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status, and reset pins are available on the serial programming port. The two startup mode pins determine what happens after a reset—the Rabbit 2000 is either cold-booted or the program begins executing at address 0x0000. These two SMODE pins can be used as general inputs once the cold boot is complete. The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is present. The status output has three different programmable functions: 1. It can be driven low on the first op code fetch cycle. 2. It can be driven low during an interrupt acknowledge cycle. 3. It can also serve as a general-purpose output. The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the onboard peripheral circuits on the RabbitCore module. The serial programming port can be used to force a hard reset on the RabbitCore module by asserting the /RESET_IN signal. Refer to the Rabbit 2000 Microprocessor User’s Manual for more information. 26 Wildcat (BL2000) 3.5 A/D Converter Inputs The single 14-channel A/D converter used in the BL2000 has a resolution of 12 bits (models BL2000 and BL2020) or 10 bits (models BL2010 and BL2030). Eleven of the 14 channels are available externally, and three are used internally for the reference voltages: 4.096 V (V ), 2.048 V (V /2), and Analog Ground. These internal voltages can be used to check ref ref the functioning of the A/D converter. The A/D converter only measures voltages between 0 V and the applied reference voltage. Therefore, each external input has circuitry that provides scaling and buffering. The first four external inputs are scaled and buffered to provide the user with an input impedance of 1 MΩ and a range of -10.24 V to +10.24 V. The remaining five or seven inputs are not buffered, but are scaled to provide inputs that can range from 0 V to +49 V. Figure 17 shows the buffered A/D converter inputs. ����.? ����.? ��� ����3� � �� ���� �*���� ���� ���� ���� Figure 17. Buffered A/D Converter Inputs The op-amp is powered from the +V supply. The 1 MΩ and 200 kΩ resistors set the gain (scale factor), which is 0.2 in this case. This results in a dynamic input range of 4.096 V ÷ 0.2 or 20.48 V. The center point of this range is set by the 1.707 V reference voltage. With the reference set to 1.707 V, the center point is at 0 V and the input voltage can range from -10.24 V to +10.24 V. To maintain the best accuracy, the input range should be limited to -10.0 V to +10.0 V. The five or seven unbuffered inputs have an impedance of 12 kΩ and a scale factor of 0.0833, which provides for an input voltage range of 0 V to 49.15 V. Accuracy is main- tained over the specified voltage range from 0 V to 48 V DC. The analog inputs can also be used as digital inputs when required. In this case a lower quality 10-bit D/A converter can be used, and the software would assign a 1 or 0 to a volt- age based on whether it is above or below a particular threshold. See the digIn function description for more information. User’s Manual 27 3.6 D/A Converter Outputs Figure 18 shows the analog voltage reference circuit. �� ����� ���A��� ���������� ��� � � � &�- ����� ����2? ���3� �@���A���? ���3� ����2? Figure 18. Analog Reference Voltages This circuit generates the 4.096 V reference voltage, which is used by the A/D converter and optionally by the two D/A converters. This sets the operating range of the A/D con- verter and the D/A converters (0–4.096 V). To use the full accuracy of the A/D converter and the D/A converters, this voltage must be accurate to the same degree. Under normal operation, the 453 Ω resistor is not installed. The reference zener diode in combination with the 100 Ω resistor form a shunt regulator. The 4.096 V reference voltage then feeds the A/D converter, the D/A converters, and the voltage divider composed of the 10 kΩ and the 14 kΩ resistors. The voltage divider generates a second reference voltage of 1.707 V to feed the four op-amps for the buffered A/D converter inputs. The reference voltage can be ratiometric rather than absolute. This is done by removing the zener diode and installing the 453 Ω resistor. With this arrangement, the reference voltages follow changes in the power supply voltages Vcc and V+, which is a filtered ver- sion of Vcc. This type of measurement circuit is preferred by some customers whose sen- sors are powered from the Vcc supply and hence the outputs track Vcc. A jumper on header JP3 allows the D/A converters to be powered either from the 4.096 V reference (factory default) or from the analog supply +V. The D/A converters use their power source also as the reference input, so normally powering the D/A converters from the more accurate 4.096 V reference is best. However, should a customer desire more dynamic range (0–5 V rather than 0–4.096 V), the jumper across JP3 can be set to power the D/A converters from +V. When powered from the +V supply, the outputs of the D/A converters will always be ratiometric, independent of whether the zener diode is installed. 28 Wildcat (BL2000) �@�!��� (’B�,1*,’ Only the BL2000 and the BL2020 models are stuffed with D/A converters. The D/A con- verters provide only a voltage output. This means that in order to maintain the maximum accuracy of the D/A converters, only a small amount of current should be drawn from the D/A converter output (of the order of µA). With D/A converters installed, the user has the option of using an unbuffered A/D con- verter input to read the output of a D/A converter or one of the two fixed voltages +V or Vcc. The standard BL2000 configuration is for A/D converter channels 9 and 10 to moni- tor D/A converter channels 0 and 1 respectively. Figure 19 shows the D/A converter outputs with buffer amplifiers, which may be used to increase the D/A converter output voltage range to 0 V to +10 V. ��� ���! ���� ���� � ���� ; � ���� ; Figure 19.

The standard models come with 128K of SRAM. Table 3 lists the jumper settings for the jumpers used to set the SRAM size. The “jumpers” are 0 Ω surface-mounted resistors. Table 3.

The BL2000 comes with one 256K flash memory. Table 3 lists the jumper settings for the jumpers used to set the SRAM size. The “jumpers” are 0 Ω surface-mounted resistors. NOTE: Rabbit recommends that any customer applications should not be constrained by the sector size of the flash memory since it may be necessary to change the sector size in the future. A Flash Memory Bank Select jumper configuration option exists at JP2 with 0 Ω surface- mounted resistors. This option, used in conjunction with some configuration macros, allows Dynamic C to compile two different co-resident programs for the upper and lower halves of the 256K flash in such a way that both programs start at logical address 0000. This is useful for applications that require a resident download manager and a separate downloaded program. See Technical Note 218, Implementing a Serial Download Man- ager for a 256K Flash, for details. 30 Wildcat (BL2000) ������ ��� ��� ��� ��� ��� ��� ��� � �� �� ��� ��� ��� ��� ��� ��� �� ��� ��� ��� ���� ��� �� �� ��� !� ��� ��������� �����!������������ ������������������ �����������!�����! ������������������ ���� ���� ������ ��� ��� ��� ��� ��� ��� ��� � �� �� ��� ��� ��� ��� ��� ��� �� ��� ��� ��� ���� ��� �� �� ��� !� ��� ��������� �����!������������ ��������� ��� ������ �����������!�����! ������������������ ���� ���� 3.8 Programming Cable The programming cable is used to connect the BL2000’s programming port to a PC serial COM port. The programming cable converts the RS-232 voltage levels used by the PC serial port to the TTL voltage levels used by the Rabbit 2000. When the PROG connector on the programming cable is connected to the BL2000’s programming header, programs can be downloaded and debugged over the serial interface. The DIAG connector of the programming cable may be used on the BL2000’s programming header with the BL2000 operating in the Run Mode. This allows the programming port to be used as a regular serial port. 3.8.1 Changing Between Program Mode and Run Mode The BL2000 is automatically in Program Mode when the PROG connector on the pro- gramming cable is attached to the BL2000, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 2000 is reset, the operating mode is determined by the status of the SMODE pins. When the programming cable’s PROG connector is attached, the SMODE pins are pulled high, placing the Rabbit 2000 in the Program Mode. When the programming cable’s PROG connector is not attached, the SMODE pins are pulled low, causing the Rabbit 2000 to operate in the Run Mode. ��������7��� $���7��� �* �������.*(& �’, ����������������� /0(123�4(%. �*+*(’,�’,-’ ����� ��� ��� ���� ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� �� �� �� �� �� �� �� �� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� ���� ���� ����� �� ��� �� ����� ��! �� ��� �� �� ����� �� ��! �� ��� �� �� �� �� ��� �� �� ��� �� �� �� �� �� �! �� �! �� �� ���� �� �! �� �! �� �� �� �� ��� �� �� ������ ��� ��� ��� ��� ��� ��� ��� ��� ���� ��� ���� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��! ��! �� ���� ������ ���� ���� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ���� ���� ��� ��� ��� ��� � � ��! ��! ��� ��� �� �� �� �� �� �� �� �� ��� ��� �� �� ��� ��� �� �� � � � � �� �� ��� ��! ��� ��!

BL2000 Program Mode and Run Mode Setup A program “runs” in either mode, but can only be downloaded and debugged when the Jackrabbit is in the Program Mode. Refer to the Rabbit 2000 Microprocessor User’s Manual for more information on the pro- gramming port and the programming cable.

Older BL2000 boards (Rabbit 2000 microprocessors labeled IQ2T) have one external interrupt available—see Technical Note TN301, Rabbit 2000 Microprocessor Interrupt Problem, for further information on how to use this interrupt on the older boards. 3.9.2 Clock Doubler The BL2000 takes advantage of the Rabbit 2000 microprocessor’s internal clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emis- sions. The 22.1 MHz frequency is generated using an 11.0592 MHz crystal. The clock doubler is disabled automatically in the BIOS for crystals with a frequency above 12.9 MHz. The clock doubler may be disabled if 22.1 MHz clock speeds are not required. Disabling the Rabbit 2000 microprocessor’s internal clock doubler will reduce power consumption and further reduce radiated emissions. The clock doubler is disabled with a simple config- uration macro as shown below. 1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler. The clock doubler is enabled by default, and usually no entry is needed. If you need to specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to always enable the clock doubler. The clock speed will be doubled as long as the crystal frequency is less than or equal to 26.7264 MHz. 3. Click OK to save the macro. The clock doubler will now remain off whenever you are in the project file where you defined the macro. 32 Wildcat (BL2000) 3.9.3 Spectrum Spreader BL2000 boards that carry the CE mark have a Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate EMI problems. By default, the spectrum spreader is on automatically for BL2000 boards that carry the CE mark when used with Dynamic C 7.32 or later versions, but the spectrum spreader may also be turned off or set to a stronger setting. The means for doing so is through a simple configuration macro as shown below. 1. Select the “Defines” tab from the Dynamic C Options > Project Options menu. 2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line ENABLE_SPREADER=1 For strong spreading, add the line ENABLE_SPREADER=2 To disable the spectrum spreader, add the line ENABLE_SPREADER=0 NOTE: The strong spectrum-spreading setting is unnecessary for the BL2000. 3. Click OK to save the macro. The spectrum spreader will now remain off whenever you are in the project file where you defined the macro. There is no spectrum spreader functionality for BL2000 boards that do not carry the CE mark or when using any BL2000 with a version of Dynamic C prior to 7.30. User’s Manual 33 34 Wildcat (BL2000) 4. SOFTWARE Dynamic C is an integrated development system for writing embedded software. It runs on an IBM-compatible PC and is designed for use with Rabbit-based single-board computers and other devices based on the Rabbit microprocessor. Chapter 4 provides the libraries, function calls, and sample pro- grams related to the BL2000. 4.1 An Overview of Dynamic C Dynamic C has been in use worldwide since 1989. It is specially designed for program- ming embedded systems, and features quick compile and interactive debugging. A com- plete reference guide to Dynamic C is contained in the Dynamic C User’s Manual. You have a choice of doing your software development in the flash memory or in the data SRAM included on the Jackrabbit. The flash memory and SRAM options are selected with the Options > Project Options > Compiler menu. The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. The disadvantage is that the code and data might not both fit in RAM. NOTE: An application can be developed in RAM, but cannot run standalone from RAM after the programming cable is disconnected. All standalone applications can only run from flash memory. NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of the flash memory market, the Jackrabbit and Dynamic C were designed to accommo- date flash devices with various sector sizes. Developing software with Dynamic C is simple. Users can write, compile, and test C and assembly code without leaving the Dynamic C development environment. Debugging occurs while the application runs on the target. Alternatively, users can compile a program to an image file for later loading. Dynamic C runs on PCs under Windows 95 and later. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles. User’s Manual 35 Dynamic C has a number of standard features:  Full-feature source and/or assembly-level debugger, no in-circuit emulator required.  Royalty-free TCP/IP stack with source code and most common protocols.  Hundreds of functions in source-code libraries and sample programs: X Exceptionally fast support for floating-point arithmetic and transcendental functions. X RS-232 and RS-485 serial communication. X Analog and digital I/O drivers. 2 X I C, SPI, GPS, file system. X LCD display and keypad drivers.  Powerful language extensions for cooperative or preemptive multitasking  Loader utility program to load binary images into Rabbit-based targets in the absence of Dynamic C.  Provision for customers to create their own source code libraries and augment on-line help by creating “function description” block comments using a special format for library functions.  Standard debugging features: X Breakpoints—Set breakpoints that can disable interrupts. X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware. X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and machine cycle times. Switch between debugging at machine-code level and source-code level by simply opening or closing the disassembly window. X Watch expressions—Watch expressions are compiled when defined, so complex expressions including function calls may be placed into watch expressions. Watch expressions can be updated with or without stopping program execution. X Register window—All processor registers and flags are displayed. The contents of general registers may be modified in the window by the user. X Stack window—shows the contents of the top of the stack. X Hex memory dump—displays the contents of memory at any address. X STDIO window—printf outputs to this window and keyboard input on the host PC can be detected for debugging purposes. printf output may also be sent to a serial port or file. 36 Wildcat (BL2000) 4.1.1 Upgrading Dynamic C 4.1.1.1 Patches and Bug Fixes Dynamic C patches that focus on bug fixes are available from time to time. Check the Web site www.rabbit.com/support/ for the latest patches, workarounds, and bug fixes. The default installation of a patch or bug fix is to install the file in a directory (folder) dif- ferent from that of the original Dynamic C installation. Rabbit recommends using a differ- ent directory so that you can verify the operation of the patch without overwriting the existing Dynamic C installation. If you have made any changes to the BIOS or to libraries, or if you have programs in the old directory (folder), make these same changes to the BIOS or libraries in the new directory containing the patch. Do not simply copy over an entire file since you may overwrite a bug fix; of course, you may copy over any programs you have written. Once you are sure the new patch works entirely to your satisfaction, you may retire the existing installation, but keep it available to handle legacy applications. 4.1.1.2 Upgrades Dynamic C installations are designed for use with the board they are included with, and are included at no charge as part of our low-cost kits. Dynamic C is a complete software development system, but does not include all the Dynamic C features. Rabbit also offers add-on Dynamic C modules containing the popular µC/OS-II real-time operating system, as well as PPP, Advanced Encryption Standard (AES), and other select libraries. In addi- tion to the Web-based technical support included at no extra charge, a one-year telephone- based technical support module is also available for purchase. User’s Manual 37 4.2 Sample Programs Sample programs are provided in the Dynamic C SAMPLES folder. The sample program PONG.C demonstrates the output to the STDIO window. The various directories in the SAMPLES folder contain specific sample programs that illustrate the use of the correspond- ing Dynamic C libraries. The SAMPLES\BL2000 folder provides sample programs specific to the BL2000. Each sample program has comments that describe the purpose and function of the program. Fol- low the instructions at the beginning of the sample program. To run a sample program, open it with the File menu (if it is not still open), compile it using the Compile menu, and then run it by selecting Run in the Run menu. The BL2000 must be in Program mode (see Section 3.8, “Programming Cable,”) and must be connected to a PC using the programming cable as described in Section 2.1, “BL2000 Connections.” More complete information on Dynamic C is provided in the Dynamic C User’s Manual. 4.2.1 General BL2000 Sample Programs  BOARD_ID.C—This program is used to identify the model of BL2000 being used, and displays that information in the STDIO window.  COUNTLEDS.C—This program will count from 0 to 31 in binary, using the four gen- eral-purpose LEDs, DS4–DS7, and the Processor Bad LED, DS8. The LEDs are used in reverse logical order to minimize the cycling of the relay, which is slaved to the same output as DS4.  LEDS_4.C—This program creates four “devices” (lights), and four buttons to toggle them. Users can view the devices with their Web browser, and change the status of the lights. If the Demonstration Board is connected to the BL2000, the lights on the Dem- onstration Board will match the ones on the Web page. See Appendix D for hookup instructions for the Demonstration Board. 4.2.2 Digital I/O The following sample programs are found in the IO subdirectory in SAMPLES/BL2000.

RELAY.C—Demonstrates how to control the relay on the BL2000. 4.2.3 Serial Communication The following sample programs are found in the RS232 subdirectory in SAMPLES/BL2000.  PUTS.C—Transmits and then receives an ASCII string on Serial Ports B and C. It also displays the serial data received from both ports in the STDIO window.  RELAYCHR.C—This program echoes characters over Serial Port B to Serial Port C. It must be run with a serial utility such as Hyperterminal. The following sample programs are found in the RS485 subdirectory in SAMPLES/BL2000.  MASTER.C—This program demonstrates a simple RS-485 transmission of lower case letters to a slave BL2000. The slave will send back converted upper case letters back to the master BL2000 and display them in the STDIO window. Use SLAVE.C to program the slave BL2000.  SLAVE.C—This program demonstrates a simple RS-485 transmission of lower case letters to a slave BL2000. The slave will send back converted upper case letters back to the master BL2000 and display them in the STDIO window. Use MASTER.C to program the master BL2000. 4.2.4 A/D Converter Inputs The following sample programs are found in the ADC subdirectory in SAMPLES/BL2000.  AD_CALIB.C—Demonstrates how to recalibrate an A/D converter channel using two known voltages to generate two coefficients, gain and offset, which are rewritten into the user block data area. The voltage that is being monitored is displayed continuously. Note that this sample program will overwrite the calibration constants set at the factory.  AD1.C—Demonstrates how to access the A/D internal test voltages in both the TLC2543 and TLC1543 A/D converter chips. The program reads the A/D internal volt- ages and then uses the STDIO window to display the RAW data.  AD2.C—Demonstrates how to access the A/D channels using the anaInVolt function. The program uses the STDIO window to display the voltage that is being monitored.  AD3.C—Demonstrates how to access the A/D converter channels with the low-level A/D driver. The program uses the STDIO window to display the voltage that is being monitored on all the A/D channels using the low-level A/D driver.  AD4.C—Demonstrates how to use the A/D converter channels with the low-level A/D driver. The program uses the STDIO window to display the voltage (average of 10 sam- ples) that is being monitored on all the A/D converter channels using the low-level A/D driver. User’s Manual 39 4.2.5 D/A Converter Outputs The following sample programs are found in the DAC subdirectory in SAMPLES/BL2000.  DACAL.C—This program demonstrates how to recalibrate an D/A converter channel using two known voltages, and defines the two coefficients, gain and offset, that will be rewritten into the D/A converter's EEPROM simulated in flash memory. Note that this sample program will overwrite the calibration constants set at the factory.  DAOUT1.C—This program outputs a voltage that can be read with a voltmeter. The out- put voltage is computed using the calibration constants that are read from the EEPROM simulated in flash memory.  DAOUT2.C—This program demonstrates the use of both the D/A and the A/D convert- ers. The user selects both the D/A converter and A/D channel to be used, then sets the D/A converter output voltage to be read by the A/D channel. All activity will be dis- played in the STDIO window. 4.2.6 Real-Time Clock If you plan to use the real-time clock functionality in your application, you will need to set the real-time clock. You may set the real-time clock using the SETRTCKB.C sample pro- gram from the Dynamic C SAMPLES\RTCLOCK folder. The RTC_TEST.C sample pro- gram in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how to read and set the real-time clock 4.2.7 TCP/IP Sample Programs TCP/IP sample programs are described in Chapter 5. 40 Wildcat (BL2000) 4.3 BL2000 Libraries Two library directories are used to develop applications for the BL2000.  BL2000-—libraries associated with features specific to the BL2000.  TCPIP—libraries specific to using TCP/IP functions on the BL2000. Other generic functions applicable to all devices based on the Rabbit 2000 microprocessor are described in the Dynamic C Function Reference Manual.

SEE ALSO digOut, digIn, serMode User’s Manual 43 4.4.2 Digital I/O int digIn(int channel); Reads the state of an input channel: IN0–IN10—standard digital inputs, ± 36 V DC IN11–IN14—pseudo digital inputs using A/D converter inputs ADC0–ADC3, ± 10 V DC IN15–IN19—pseudo digital inputs using A/D converter inputs ADC4–ADC8, 0 V to 48 V DC IN20–IN21—pseudo digital inputs using A/D converter inputs DAC0–DAC1, 0 V to 48 V DC (BL2010 and BL2030) The threshold is fixed at 2.40 V for channels IN0–IN10. Anything below 2.40 V is a logic 0, and any- thing higher than or equal to 2.40 V is a logic 1. The default threshold for channels IN11–IN21 is also set to 2.40 V. The threshold for these channels may be changed by adding the following two lines to your program. #undef THRESHOLD #define THRESHOLD xx.xx where xx.xx is the desired threshold voltage. Anything below the threshold value is a logic 0, and any- thing higher than or equal to the threshold value is a logic 1. PARAMETER channel is the input channel number (0–21) RETURN VALUE The state of the input (0 or 1). SEE ALSO brdInit, digOut void digOut(int channel, int value); Sets the state of a digital output (OUT0–OUT9). The default setting for the function is for current-sinking outputs. To change from sinking to sourcing outputs, add the following two lines at the beginning of your program. #undef OUTPUT_DRIVE #define OUTPUT_DRIVE SOURCING The relay is driven by PA0, which is the same Rabbit 2000 parallel port that drives OUT0 and LED DS4. OUT0 therefore works in parallel with the relay output. Rabbit therefore recommends that you do not use OUT0 for a digital output when you are using the relay. PARAMETERS channel is the output channel number (0–9). value is the output value (0 or 1). SEE ALSO brdInit, digIn 44 Wildcat (BL2000) 4.4.3 Serial Communication Library files included with Dynamic C provide a full range of serial communications sup- port. The RS232.LIB library provides a set of circular-buffer-based serial functions. The PACKET.LIB library provides packet-based serial functions where packets can be delim- ited by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries provide blocking functions, which do not return until they are finished transmit- ting or receiving, and nonblocking functions, which must be called repeatedly until they are finished.

USING THE TCP/IP FEATURES Chapter 5 provides an introduction to using the TCP/IP features on your BL2000 board. 5.1 TCP/IP Connections Before proceeding you will need to have the following items.  If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card (available from your favorite computer supplier) installed in a PC.  Two RJ-45 straight through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable. The Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool kit. More information is available at www.rabbit.com. 1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting Started.” 2. Ethernet Connections If you do not have access to an Ethernet network, use a crossover Ethernet cable to con- nect the BL2000 to a PC that at least has a 10Base-T Ethernet card. If you have Ethernet access, use a straight through Ethernet cable to establish an Ethernet connection to the BL2000 from an Ethernet hub. These connections are shown in Figure 21. BL2000 BL2000 Board Board User’s PC Ethernet cables Ethernet To additional crossover network cable Hub elements Direct Connection Direct Connection Using a Hub (Network of 2 computers) Figure 21. Ethernet Connections User’s Manual 53 The PC running Dynamic C through the serial programming port on the BL2000 does not need to be the PC with the Ethernet card. 3. Apply Power Plug in the AC adapter. The BL2000 is now ready to be used. NOTE: A hardware RESET is accomplished by unplugging the AC adapter, then plug- ging it back in, or by momentarily grounding the board reset input at pin 9 on screw ter- minal header J2. When working with the BL2000, the green LNK light is on when a program is running and the board is properly connected either to an Ethernet hub or to an active Ethernet card. The orange ACT light flashes each time a packet is received. 54 Wildcat (BL2000) 5.2 TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require that you connect your PC and the BL2000 together on the same network. This network can be a local private network (pre- ferred for initial experimentation and debugging), or a connection via the Internet. 5.2.1 How to Set IP Addresses in the Sample Programs With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. Instead of the MY_IP_ADDRESS and other macros, you will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro. 1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program. 2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway to 10.10.6.1. If you would like to change the default values, for example, to use an IP address of 10.1.1.2 for the BL2000 board, and 10.1.1.1 for your PC, you can edit the values in the section that directly follows the “General Configuration” comment in the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP directory. 3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB file. There are some other “standard” configurations for TCPCONFIG that let you select differ- ent features such as DHCP. Their values are documented at the top of the TCP_CONFIG.LIB library. More information is available in the Dynamic C TCP/IP User’s Manual. IP Addresses Before Dynamic C 7.30 Most of the sample programs such as shown in the example below use macros to define the IP address assigned to the board and the IP address of the gateway, if there is a gateway. #define MY_IP_ADDRESS "10.10.6.170" #define MY_NETMASK "255.255.255.0" #define MY_GATEWAY "10.10.6.1" #define MY_NAMESERVER "10.10.6.1" In order to do a direct connection, the following IP addresses can be used for the BL2000: #define MY_IP_ADDRESS "10.1.1.2" #define MY_NETMASK "255.255.255.0" // #define MY_GATEWAY "10.10.6.1" // #define MY_NAMESERVER "10.10.6.1" In this case, the gateway and nameserver are not used, and are commented out. The IP address of the board is defined to be 10.1.1.2. The IP address of you PC can be defined as 10.1.1.1. User’s Manual 55 5.2.2 How to Set Up your Computer’s IP Address for a Direct Connection When your computer is connected directly to the BL2000 via an Ethernet connection, you need to assign an IP address to your computer. To assign the PC the address 10.10.6.101 with the netmask 255.255.255.0, do the following. Click on Start > Settings > Control Panel to bring up the Control Panel, and then dou- ble-click the Network icon. Depending on which version of Windows you are using, look for the TCP/IP Protocol/Network > Dial-Up Connections/Network line or tab. Double- click on this line or select Properties or Local Area Connection > Properties to bring up the TCP/IP properties dialog box. You can edit the IP address and the subnet mask directly. (Disable “obtain an IP address automatically.”) You may want to write down the existing values in case you have to restore them later. It is not necessary to edit the gate- way address since the gateway is not used with direct connect. BL2000 IP 10.10.6.101 Board Netmask 255.255.255.0 User’s PC Ethernet crossover cable Direct Connection PC to BL2000 Board 56 Wildcat (BL2000) 5.3 Run the PINGME.C Sample Program Connect the crossover cable from your computer’s Ethernet port to the BL2000’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C. When the program starts run- ning, the green LNK light on the BL2000 should be on to indicate an Ethernet connection is made. (Note: If the LNK light does not light, you may not have a crossover cable, or if you are using a hub perhaps the power is off on the hub.) The next step is to ping the board from your PC. This can be done by bringing up the MS- DOS window and running the pingme program: ping 10.10.6.100 or by Start > Run and typing the entry ping 10.10.6.100 Notice that the orange ACT light flashes on the BL2000 while the ping is taking place, and indicates the transfer of data. The ping routine will ping the board four times and write a summary message on the screen describing the operation. User’s Manual 57 5.4 Running More Sample Programs With a Direct Connection The program SSI.C (SAMPLES\BL2000\TCPIP\) demonstrates how to make the BL2000 a Web server. This program allows you to turn the LEDs on an attached Demon- stration Board from the Tool Kit on and off from a remote Web browser. LEDs DS4–DS8 on the BL2000 will match those on the Web page. As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program. http://10.10.6.100 Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. The sample program SMTP.C (SAMPLES\BL2000\TCPIP\) allows you to send an E-mail when a switch on the Demonstration Board is pressed. Follow the instructions included with the sample program. The sample program TELNET.C (SAMPLES\BL2000\TCPIP\) allows you to communi- cate with the BL2000 using the Telnet protocol. This program takes anything that comes in on a port and sends it out Serial Port B. It uses digital input IN0 to indicate that the TCP/IP connection should be closed, and it uses high-current output OUT0 to indicate that there is an open connection. You may change the digital input and output to suit your application needs. Run the Telnet program on your PC (Start > Run telnet 10.10.6.100). As long as you have not modified the TCPCONFIG 1 macro in the sample program, the IP address is 10.10.6.100 as shown; otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. Each character you type will be printed in Dynamic C's STDIO window, indicating that the board is receiving the characters typed via TCP/IP. 5.5 Where Do I Go From Here?

POWER SUPPLY Appendix C describes the power circuitry distributed on the BL2000. C.1 Power Supplies Power is supplied to the BL2000 via a mini phone jack located at J7 or through the screw terminal strip, header J2. The BL2000 itself is protected against reverse polarity by a diode at D1 as shown in Figure C-1. ���� �����<������������������� �77 ���*(�� �� ���� �� � ��� �� ��� �� ��! � � � ���� ���H? �� ����H< ����H? � � � �� �� ������ �� �� �����! Figure C-1. BL2000 Power Supply Capacitor C28 provides surge current protection for the voltage regulator, and allows the external power supply to be located some distance away from the BL2000. A switching power regulator is used. The input voltage range is from 9 V to 40 V. The BL2000 can alternatively be powered by 24 V AC. In this case D1 and C28 act as a half-wave rectifier to produce approximately 40 V DC at the input of the switching regula- tor, U12. Although a significant drop will be measured at DCIN, the voltage will never drop below +9 V DC. As long as the minimum input level is maintained at the input to the regulator, Vcc will be held at +5 V DC. Pin 12 on header J9 can be configured to either supply Vcc (0 Ω surface-mounted resistor installed at R160) or GND (0 Ω surface-mounted resistor installed at R161). When using pin 12 on header J9 to supply Vcc, take care not to draw more than 25 mA current from this pin, especially if you are using 24 V AC as your +RAW input power supply. The R160 and R161 locations are shown in Figure A-4. User’s Manual 73 ����� �� C.1.1 Power for Analog Circuits Power to the analog circuits is provided by way of a two-stage low-pass filter, which iso- lates the analog section from digital noise generated by the other components. The analog power voltage +V powers the op-amp for the buffered A/D converter inputs, the A/D con- verter, and the 4.096 V reference circuit. The two D/A converters can be powered either from the reference, which is the standard, or from +V when ratiometric measurements are desired. The maximum current draw on +V is less than 10 mA. There are three digital grounds, one on each of the screw-terminal headers associated with the digital functions (J2, J8, and J9). The digital ground and the analog ground share a sin- gle split ground plane on the board, with the analog ground connected at a single point to the digital ground by a 0 Ω resistor (R87). This is done to minimize digital noise in the analog circuits and to eliminate the possibility of ground loops. External connections to analog ground are made on screw-terminal header J4. C.2 Batteries and External Battery Connections The SRAM and the real-time clock have battery backup. Power to the SRAM and the real- time clock (VRAM) is provided by two different sources, depending on whether the main part of the BL2000 is powered or not. When the BL2000 is powered normally, and Vcc is within operating limits, the SRAM and the real-time clock are powered from Vcc. If power to the board is lost or falls below 4.63 V, the VRAM power will come from the battery. The reset generator circuit controls the source of power by way of its /RESET output signal. A replaceable 265 mA·h lithium battery provides power to the real-time clock and SRAM when external power is removed from the circuit board. The drain on the battery is typically less than 10 µA when there is no external power applied, and so the expected in-service life of the battery is 265 mA·h - - - --- -- -- --- -- --- -- -- - - = 3.0 years. 10 µA The drain on the battery is typically less than 4 µA when external power is applied, and so the expected BL2000 shelf life is 265 mA·h ------------------------ = 7.5 years. 4 µA A long-life 950 mA·h solder-in battery is also provided for in the board layout. Alterna- tively, an external battery may be connected to the BL2000 via header J12. The existing battery does not have to be removed when an external battery is used. 74 Wildcat (BL2000) C.2.1 Replacing the Backup Battery The battery is user-replaceable, and is fitted in a battery holder. To replace the battery, lift up on the spring clip and slide out the old battery. Use only a Panasonic CR2330 or equiv- alent replacement battery, and insert it into the battery holder with the + side facing up. NOTE: The SRAM contents and the real-time clock settings will be lost if the battery is replaced with no power applied to the BL2000. Exercise care if you replace the battery while external power is applied to the BL2000. CAUTION: There is an explosion danger if the battery is short-circuited, recharged, or replaced incorrectly. Replace the battery only with the same type or an equivalent type recommended by the battery manufacturer. Dispose of used batteries according to the battery manufacturer’s instructions. C.2.2 Battery-Backup Circuit Figure C-2 shows the battery-backup circuit. $��������������� ��� ��� ���� ���� ����#��� ���� ��3� ��3� �%�������������� ��� � ��� ���� � ���� ����#�$� � ��3� ���3� �77 ��� ���3� ��� ��� ���! �!� ���� ���� ���3� ���3� ��� ��� ��2? ��2? Figure C-2. BL2000 Backup Battery Circuit The battery-backup circuit serves three purposes:  It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting the current consumed by the real-time clock and lengthening the battery life.  It ensures that current can flow only out of the battery to prevent charging the battery.  A voltage, VOSC, is supplied to U14, which keeps the 32.768 kHz oscillator working when the voltage begins to drop. VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to the BL2000. User’s Manual 75 C.2.3 Power to VRAM Switch The VRAM switch, shown in Figure C-3, allows the battery backup to provide power when the external power goes off. The switch provides an isolation between Vcc and the battery when Vcc goes low. This prevents the Vcc line from draining the battery. ��� ���� �!! ��� ! ?������ �!� ���3� ���� � >����� �����!�� ���3� Figure C-3. VRAM Switch Field-effect transistor Q9 is needed to provide a very small voltage drop between Vcc and VRAM (<100 mV, typically 10 mV) so that the board components powered by Vcc will not have a significantly different voltage than VRAM. When the BL2000 is not in reset, the /RESET line will be high. This turns on Q8, causing its collector to go low. This turns on Q9, allowing VRAM to nearly equal Vcc. When the BL2000 is in reset, the /RESET line will go low. This turns off Q8 and Q9, pro- viding an isolation between Vcc and VRAM. 76 Wildcat (BL2000) C.2.4 Reset Generator The BL2000 uses a reset generator, U4, to reset the Rabbit 2000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 4.50 V and 4.75 V, typically 4.63 V. The reset can be initiated either externally or by a watchdog timeout (WDTOUT) on the Rabbit 2000 microprocessor. ���� >����� �� ����� ������ ��! ��� ��������� ���� ���3� ����2? ����3� ��� ��� �$� ����� Figure C-4. Reset Generator NOTE: The Dynamic C function chkWDTO is not able to detect whether a watchdog timeout has occurred on the BL2000. The GCSR status bits are read and stored by the BIOS, and the reset status bit would normally change once a reset has occurred. How- ever, since WDTOUT is tied to the reset generator, a watchdog timeout forces a hard- ware reset, followed by the BIOS reading and storing the status bits corresponding to power-up or reset. To use chkWDTO to detect a watchdog timeout, remove D15 (located on the bottom side of the BL2000). User’s Manual 77 C.3 Chip Select Circuit Figure C-5 shows a schematic of the chip select circuit. ���� ���� ����3� >����� � >��� � ���� >����� � ���3� ��� ��2? Figure C-5. Chip Select Circuit The current drain on the battery in a battery-backed circuit must be kept at a minimum. When the BL2000 is not powered, the battery keeps the SRAM memory contents and the real-time clock (RTC) going. The SRAM has a powerdown mode that greatly reduces power consumption. This powerdown mode is activated by raising the chip select (CS) signal line. Normally the SRAM requires Vcc to operate. However, only 2 V is required for data retention in powerdown mode. Thus, when power is removed from the circuit, the battery voltage needs to be provided to both the SRAM power pin and to the CS signal line. The CS control circuit accomplishes this task for the SRAM’s chip select signal line. In a powered-up condition, the CS control circuit must allow the processor’s chip select signal /CS1 to control the SRAM’s CS signal /CSRAM. So, with power applied, /CSRAM must be the same signal as /CS1, and with power removed, /CSRAM must be held high (but only needs to be battery voltage high). Q3 and Q4 are MOSFET transistors with com- plementary polarity. They are both turned on when power is applied to the circuit. They allow the CS signal to pass from the processor to the SRAM so that the processor can peri- odically access the SRAM. When power is removed from the circuit, the transistors will turn off and isolate /CSRAM from the processor. The isolated /CSRAM line has a 100 kΩ pullup resistor to VRAM (R101). This pullup resistor keeps /CSRAM at the VRAM volt- age level (which under no power condition is the backup battery’s regulated voltage at a little more than 2 V). 78 Wildcat (BL2000) Transistors Q3 and Q4 are of opposite polarity so that a rail-to-rail voltage can be passed. When the /CS1 voltage is low, Q4 will conduct. When the /CS1 voltage is high, Q3 con- ducts. It takes time for the transistors to turn on, creating a propagation delay. This propa- gation delay is typically very small, about 10 ns to 15 ns. The signal that turns the transistors on is a high on the processor’s reset line, /RESET. When the BL2000 is not in reset, the reset line will be high, turning on n-channel Q4 directly and p-channel FET Q3 by way of Q8. When the board is in reset both Q3 and Q4 are off, isolating /CSRAM and allowing it to be pulled to VRAM. User’s Manual 79 80 Wildcat (BL2000) APPENDIX D. DEMONSTRATION BOARD Appendix D shows how to connect the Demonstration Board to the BL2000. D.1 Connecting Demonstration Board Before running sample programs based on the Demonstration Board, you will have to con- nect the Demonstration Board from the BL2000 Tool Kit to the BL2000 board. Proceed as follows. 1. Use the wires included in the BL2000 Tool Kit to connect header J1 on the Demonstra- tion Board to header J8 and J9 on the BL2000. The connections are shown in Figure D-1 for sample programs DIGIN.C, DIGOUT.C, and SMTP.C, and in Figure D-2 for sample program ANADIGIN.C. 2. Make sure that your BL2000 is connected to your PC and that the power supply is con- nected to the BL2000 and plugged in as described in Chapter 2, “Getting Started.” User’s Manual 81 ������ ��� ��� ��� ��� ��� ��� ��� � �� �� ��� ��� ��� ��� ��� ��� �� �� ��� <� ��� ��� ��������II�� �������#� ���� ��� �� �� ���������� �������#� ���� ������ �������#� ��� !� ���� ������ �������#� ���������� ��� ��������� ������" �����!������������ ��������� ������������������ ��� ������ �����������!�����! ��� ������ ������������������ ���� ��������� ��������� ��������� ���� ���� ��� �" ���# ��� ��� ���# ���� �$�� �$�� �$�� �$�� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� �� �� �� �� ��� ��� ��� ���� ��� ��� ���� ���� ���� ����� ���� ���� ���� �� ��� �� ����� ��! �� ��� �� �� �� �� �� ��� �! �� �� �� �� �! ���� �� ��� ��� ��� ��� ��� ��� ���� ��� ��� ��� ��� ��� ��! �� ���� ���� ��� ��� ��� ��� ��� ��� ���� ��� ��� � ��! ��� �� �� �� �� ��� �� ��� �� � � �� ��� ��! ������ "� �� � ��� � ��� ��� ��� � ��� �� � � � ��! ��������5%=@ ��� ��� � �� ��� �� � ��� ��� ��� �� �� �� ��� ��� ��� � ��� ��� ��� ��� ��� ��� ��� ��� ��! �� �� �� �! ��� ��� ��� �� �� �� �������� ��� ��� ��� ��� ��� ��� ��� ��! ��� ��� ��� ���� ��� ��� ��� ��� ��� ���� ��� ��� ��� ��� ��� �� ��� ��� �! ��� ��� ��� ��� ��� ��� ��� ��! ���� ���� ���! ��� ���� ���� ���� ���� ���� ���� ���� ���� �� ��� �� ��� /0�+++ ��’������� ���/���1 7���1����������98 7���1�����8 ����8�" ��� ��� ��� ��� ��� <� ��� ��� ���������������������� ��� ��� �#’$���2 ������#� ��� ��� ������#� ��II�� <�J��*2’ ���������� ���� ���� ������#� <�J��/�/0*42 ���� ���� ���� ���� ������������������������������ ���� ���� Figure D-1.

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
