1.4 CE Compliance
Equipment is generally divided into two classes.
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 frequencies
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 OP6800 has been tested and was found to be in conformity with
the following applicable immunity and emission standards. The OP6810
is also CE qualified as it is a sub-version of the OP6800. Boards that
are CE-compliant have the CE mark.
NOTE: Earlier versions of the OP6800 sold before 2003 that do not
have the CE mark are not CE-complaint.
Immunity
The OP6800 operator interfaces meet the following EN55024/1998 immunity standards.
EN61000-4-2 (ESD)
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 OP6800 operator interfaces meet the following emission standards emission stan-
dards with the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The
spectrum spreader is only available with Rev. C or higher of the Rabbit 2000 microproces-
sor. This microprocessor is used on the OP6800 operator control panels that carry the CE
mark.
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.

1.4.1 Design Guidelines
Note the following requirements for incorporating the OP6800 operator interfaces 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 OP6800 to outdoor cables, the customer is responsible for provid-
ing CE-approved surge/lightning 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. Rabbit also recommends using properly shielded I/O cables in noisy
electromagnetic environments.
While the OP6800 meets the EN61000-4-2 (ESD) requirements in that it can withstand
contact discharges of ± 4 kV and air discharges of ± 8 kV, it is the responsibility of the
end-user to use proper ESD precautions to prevent ESD damage when installing or ser-
vicing the OP6800.
Safety
For personal safety, all inputs and outputs to and from the OP6800 must not be con-
nected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC). Damage to
the Rabbit 2000 microprocessor may result if voltages outside the design range of 0 V
to 40 V DC are applied directly to any of its digital inputs.
The lithium backup battery circuit on the OP6800 has been designed to protect the bat-
tery 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 OP6800 to Other Devices
Since the OP6800 operator control panels are designed to be connected to other devices,
good EMC practices should be followed to ensure compliance. CE compliance is ulti-
mately 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.

Figure 4. Power Supply Connections
NOTE: The OP6800 itself has reverse polarity protection, but the Demonstration Board
does not. Be careful to connect the positive and negative leads as shown to avoid damag-
ing the Demonstration Board.
NOTE: If you are using your own power supply, Rabbit recommends using a 9 V to 25 V
DC power supply. The linear regulator on the Demonstration Board can handle up to
35 V, but can get extremely hot.
4. Apply power.
Plug in the AC adapter.
CAUTION: Unplug the power supply while you make or otherwise work with the connections
to the headers. This will protect your OP6800 from inadvertent shorts or power spikes.
NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in.

A repeating sequence of graphics and messages in various languages will be displayed on
the LCD, and the LEDs will flash on and off in sequence when power is first applied to the
OP6800. Try pressing the buttons on the keypad. The LED immediately above that button
will light up, and if you pressed one of the keys in the top row of the keypad, the corre-
sponding LED on the Demonstration Board will light up. Similarly, if you press one of the
switches on the Demonstration Board, the corresponding LED on the Demonstration
Board and on the OP6800 will light up.
Note that the programming cable does not have to be connected for this demonstration.
This demonstration will be replaced by a new program when the programming cable is
attached and the new program is compiled and run. The demonstration is available for
future reference in the Dynamic C SAMPLES\LCD_KEYPAD\122x32_1x7 directory as
FUN.C.
2.3 Display Contrast Adjustment
The LCD contrast is preset at the factory. If you need to adjust the contrast for optimum
display of graphics and messages, you may adjust the potentiometer at R4 located as
shown in Figure 5. Note that OP6800 units sold before 2004 did not have any provision to
adjust the contrast.

2.4 Programming Cable Connections
1. Connect the programming cable to download programs from your PC and to program
and debug the OP6800.
Connect the 10-pin PROG connector of the programming cable to header J1 on the
OP6800 RabbitCore module. Ensure that the colored edge lines up with pin 1 as shown.
(Do not use the DIAG connector, which is used for a nonprogramming serial connection.)
Connect the other end of the programming cable to a COM port on your PC. Make a note
of the port to which you connect the cable, as Dynamic C will need to have this parameter
configured. Note that COM1 on the PC is the default COM port used by Dynamic C.
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an
RS-232/USB converter (Part No. 20-151-0178) with the programming cable supplied
with the OP6800 Tool Kit. Note that not all RS-232/USB converters work with
Dynamic C.

NOTE: Be sure to use the programming cable (Part No. 101-0513) supplied with the
OP6800 Tool Kit—the programming cable has red shrink wrap around the RS-232 con-
verter section located in the middle of the cable. Programming cables from other Rabbit
kits are not designed to work with the OP6800.
2. Reset the OP6800 by unplugging the AC adapter, then plugging it back in. The OP6800
is now ready to be used.

2.5 Installing Dynamic C
If you have not yet installed Dynamic C version 7.06P2 (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 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 instal-
lation of the later version will be in a different folder, and a separate icon will appear on
your desktop.
2.6 Starting Dynamic C
Once the OP6800 is connected to your PC and to a power source, start Dynamic C by dou-
ble-clicking on the Dynamic C icon on your desktop or in your Start menu.
If you are using a USB port to connect your computer to the OP6800, choose Options >
Project Options and select “Use USB to Serial Converter.” Click OK.
Dynamic C assumes, by default, that you are using serial port COM1 on your PC. If you
are using COM1, then Dynamic C should detect the OP6800 and go through a sequence of
steps to cold-boot the OP6800 and to compile the BIOS. If the error message “Rabbit Pro-
cessor Not Detected” appears, you have probably connected to a different PC serial port
such as COM2, COM3, or COM4. You can change the serial port used by Dynamic C with
the OPTIONS menu, then try to get Dynamic C to recognize the OP6800 by selecting
Reset Target/Compile BIOS on the Compile menu. Try the different COM ports in the
OPTIONS menu until you find the one you are connected to. If you still can’t get Dynamic
C to recognize the target on any port, then the hookup may be wrong or the COM port
might not working on your PC.
If you receive the “BIOS successfully compiled …” message after pressing or
starting Dynamic C, and this message is followed by a communications error message, it
is possible that your PC cannot handle the 115,200 bps baud rate. Try changing the baud
rate to 57,600 bps as follows.
Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Change the baud rate to 57,600 bps.
12 MiniCom (OP6800)
2.7 PONG.C
You are now ready to test your programming connections 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 shows that the CPU is working. The sample program described in
Section 5.2.3, “Run the PINGME.C Demo,” tests the TCP/IP portion of the board (if you
have the OP6800 model—the OP6810 does not have an Ethernet capability).
2.8 Where Do I Go From Here?
NOTE: If you purchased your OP6800 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 OP6800 fea-
tures and develop your own applications.
The following sample programs illustrate the features and operation of the OP6800.

3.2 Digital I/O
3.2.1 Digital Inputs
The OP6800 has eight digital inputs, IN00–IN07, each with a current-limiting resistor of
27 kΩ, and protected over a range of –36 V to +36 V. The inputs are all pulled up to +5 V
as shown in Figure 9.
�88
,
,
��++�� ��---
�����&��������
���
Figure 9. OP6800 Digital Inputs
The OP6800 also has five digital inputs, IN08–IN12, each with a current-limiting resistor
of 12 kΩ, protected over a range of –25 V to +25 V, and pulled up to +5 V.
The actual switching threshold for IN00–IN12 is approximately 2.40 V. Anything below
this value is a logic 0, and anything above is a logic 1.
IN13–IN17 are connected in parallel with five of the keypad buttons. These inputs are nor-
mally pulled up, but pulling one of these inputs down is the equivalent of pressing the cor-
responding keypad key remotely.

NOTE: Remote keypad signal inputs IN13–IN17 are not protected, and can only
handle a voltage range from 0 to +5 V. These inputs were designed solely to
facilitate a remote keypad, and should not be used for other purposes.
User’s Manual 17
3.2.2 Digital Outputs
The OP6800 has 11 digital outputs, OUT00–OUT10, which can each sink up to 200 mA.
Figure 10 shows a wiring diagram for using the digital outputs.
OUT00–OUT06 can switch up to 40 V and the corresponding LEDs when the outputs are
on. OUT07–OUT10 offer protection for inductive loads when K is connected to an exter-
nal power supply; OUT07–OUT10 are not connected to the LEDs.

Figure 10. OP6800 Digital Outputs
It is possible to use an external open-collector driver to control the LEDs associated with
OUT00–OUT06. Connect the external driver to the output corresponding to the LED you
wish to control, but keep the internal driver turned off. The external driver will then con-
trol the LED.
18 MiniCom (OP6800)
3.3 Serial Communication
The OP6800 has two RS-232 serial ports, which can be configured as one RS-232 serial
channel (with RTS/CTS) or as two RS-232 (3-wire) channels using the serMode software
function call. Table 3 summarizes the options.
Table 3. 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
The OP6800 also has one RS-485 serial channel and one CMOS serial channel. The
CMOS serial channel serves as the programming port.
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, the CMOS programming port, can be oper-
ated 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
OP6800 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 commu-
nication. The OP6800 uses an 11.0592 MHz crystal, which is doubled to 22.1184 MHz. At
this frequency, the OP6800 supports standard asynchronous baud rates up to a maximum
of 230,400 bps.
3.3.1 RS-232
The OP6800 RS-232 serial communication is supported by an RS-232 transceiver. This
transceiver 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 by
an RS-232 circuit so that a +5 V input becomes approximately -10 V and 0 V is output as
+10 V. The RS-232 transceiver also provides the proper line loading for reliable commu-
nication.
RS-232 can be used effectively at the OP6800’s maximum baud rate for distances of up to
15 m.
3.3.2 RS-485
The OP6800 has one RS-485 serial channel, which is connected to the Rabbit 2000 Serial
Port D through an RS-485 transceiver. The half-duplex communication uses the Rabbit
2000’s PB6 pin to control the transmit enable on the communication line.
The OP6800 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 11.
Note that a common ground is recommended.

Figure 12. RS-485 Termination and Bias Resistors
For best performance, the bias and termination resistors in a multidrop network should
only be enabled on both end nodes of the network. Disable the termination and bias resis-
tors on any intervening OP6800 units in the network by removing both jumpers from
header JP1.
TIP: Save the jumpers for possible future use by “parking” them across pins 1–3 and 4–6
of header JP1. Pins 3 and 4 are not otherwise connected to the OP6800.

3.3.3 Programming Port
The OP6800 programming port is accessed using header J1 on the OP6800’s RabbitCore
module or through the Ethernet jack. 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 on the OP6800 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.
Alternate Uses of the 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 programming port may also be used as a serial port via the DIAG connector on the
programming cable.
In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the programming port header.
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.
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
OP6800 onboard peripheral circuits.
Refer to the Rabbit 2000 Microprocessor User’s Manual for more information.

3.3.4 Ethernet Port (OP6800 models only)
Figure 13 shows the pinout for the Ethernet port (J2 on the OP6800 module). 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 13) are always absolute, and the RJ-45 connector will work properly
with off-the-shelf Ethernet cables.

RJ-45 pinouts are sometimes numbered opposite to the way shown in Figure 13.
Two LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link
(LNK) and one to indicate Ethernet activity (ACT).
The transformer/connector assembly ground is connected to the BL2100 module printed
circuit board digital ground via a 0 Ω resistor “jumper,” R29, as shown in Figure 14.

Figure 14. Isolation Resistor R29
The factory default is for the 0 Ω resistor “jumper” at R29 to be installed. In high-noise
environments, remove R29 and ground the transformer/connector assembly directly
through the chassis ground. This will be especially helpful to minimize ESD and/or EMI
problems.

3.4 Programming Cable
The programming cable is used to connect the programming port of the OP6800 to a PC
serial COM port. The programming cable converts the RS-232 voltage levels used by the
PC serial port to the voltage levels used by the Rabbit 2000.
When the PROG connector on the programming cable is connected to the OP6800 pro-
gramming port, programs can be downloaded and debugged over the serial interface
between the PC and the Rabbit 2000.
The DIAG connector of the programming cable may be used on header J1 of the OP6800
RabbitCore module with the OP6800 operating in the Run Mode. This allows the pro-
gramming port to be used as a regular serial port.
3.4.1 Changing Between Program Mode and Run Mode
The OP6800 is automatically in Program Mode when the PROG connector on the pro-
gramming cable is attached, 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.

3.5 Other Hardware
3.5.1 Clock Doubler
The OP6800 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 global
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.
24 MiniCom (OP6800)
3.5.2 Spectrum Spreader
OP6800 operator interfaces that carry the CE mark on their RabbitCore module 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 OP6800 operator
control panels that carry the CE mark when used with Dynamic C 7.30 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 global 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 not needed for the OP6800.
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 OP6800 operator control panels that do
not carry the CE mark on their RabbitCore module or when using any OP6800 with a
version of Dynamic C prior to 7.30.
User’s Manual 25
3.6 Memory
3.6.1 SRAM
The OP6800 module is designed to accept 128K to 512K of SRAM. The standard OP6800
modules come with 128K of SRAM.
3.6.2 Flash Memory
The OP6800 is also designed to accept 128K to 512K of flash memory. The standard
OP6800 modules come with one 256K flash memory.
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 based on 0 Ω surface-mounted
resistors exists at header JP2 on the RabbitCore module. 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 pro-
grams start at logical address 0000. This is useful for applications that require a resident
download manager and a separate downloaded program. See Technical Note TN218,
Implementing a Serial Download Manager for a 256K Flash, for details.

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 OP6800.
You have a choice of doing your software development in the flash memory or in the static
RAM included on the OP6800. The flash memory and SRAM options are selected with
the 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 OP6800 and Dynamic C were designed to accommodate
flash devices with various sector sizes.
OP6800s that are special-ordered with the 512K flash/512K SRAM memory option have
two 256K flash memories. By default, Dynamic C will use only the first flash memory for
program code in these OP6800s. Uncomment the BIOS macro USE_2NDFLASH_CODE in
BIOS\RABBITBIOS.C to allow the second flash memory to hold any program code that is
in excess of the available memory in the first flash.
User’s Manual 29
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 a binary image file for later loading. Dynamic C runs on PCs under Windows 95 or
later. Programs can be downloaded at baud rates of up to 230,000 bps after the program
compiles.
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 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.

4.1 Upgrading Dynamic C
4.1.1 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.
4.1.2 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 31
4.2 Font and Bitmap Converter
A Font and Bitmap Converter tool is available to convert Windows fonts and mono-
chrome bitmaps to a library file format compatible with Rabbit’s Dynamic C applications
and graphical displays. Non-Roman characters can also be converted by applying the
monochrome bitmap converter to their bitmaps.
Start the Font and Bitmap Converter tool by double-clicking on the fbmcnvtr.exe file
in the Dynamic C directory. You then select and convert existing fonts or bitmaps. Com-
plete instructions are available via the Help menu that is in the Font and Bitmap Con-
verter tool.
Once you are done, the converted file is displayed in the editing window. Editing may be
done, but should not be necessary. Save the file as libraryfilename.lib, where
libraryfilename is a file name of your choice.
Add the library file(s) to applications with the statement #use libraryfilename.lib,
or by cutting and pasting from the library file(s) you created into the application program.
TIP: If you used the #use libraryfilename.lib statement, remember to enter
libraryfilename.lib into lib.dir, which is located in your Dynamic C
directory.
You are now ready to add the font or bitmap to your application using the glXFontInit
or the glXPutBitmap function calls.

4.3 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 illus-
trate the use of the corresponding Dynamic C libraries.
The OP6800 folder provides sample programs specific to the OP6800. Each sample pro-
gram has comments that describe the purpose and function of the program. Follow 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), then compile
and run it by pressing F9. The OP6800 must be in Program mode (see Section 3.4) and
must be connected to a PC using the programming cable as described in Section 2.1.

5. USING THE TCP/IP FEATURES
Chapter 5 discusses using the TCP/IP features on the OP6800
boards. The TCP/IP feature is not available on OP6810 versions.
5.1 TCP/IP Connections
Before proceeding you will need to have the following items.
If you don’t have an Ethernet connection, you will need to install a 10Base-T Ethernet
card (available from your favorite computer supplier) in your 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 OP6800 to a PC that at least has a 10Base-T Ethernet card.
If you have an Ethernet connection, use a straight-through Ethernet cable to establish
an Ethernet connection to the OP6800 from an Ethernet hub. These connections are
shown in Figure 19.

3. Apply Power
Plug in the AC adapter. The OP6800 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.
The green LNK light on the OP6800 Rabbitcore module is on when the OP6800 is prop-
erly connected either to an Ethernet hub or to an active Ethernet card. The orange ACT
light flashes each time a packet is received.
38 MiniCom (OP6800)
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
OP6800 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. 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 Coyote 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
library in the LIB\TCPIP directory.
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 in the LIB\TCPIP directory. 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 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 "216.112.116.155"
#define MY_NETMASK "255.255.255.248"
#define MY_GATEWAY "216.112.116.153"
In order to do a direct connection, the following IP addresses can be used for the OP6800:
#define MY_IP_ADDRESS "10.1.1.2"
#define MY_NETMASK "255.255.255.248"
// #define MY_GATEWAY "216.112.116.153"
In this case, the gateway is not used and is commented out. The IP address of the board is
defined to be 10.1.1.2. The IP address of your PC can be defined as 10.1.1.1.

5.2.2 How to Set Up Your Computer for Direct Connect
Follow these instructions to set up your PC or notebook. Check with your administrator if
you are unable to change the settings as described here since you may need administrator
privileges. The instructions are specifically for Windows 2000, but the interface is similar
for other versions of Windows.
TIP: If you are using a PC that is already on a network, you will disconnect the PC from
that network to run these sample programs. Write down the existing settings before
changing them to facilitate restoring them when you are finished with the sample pro-
grams and reconnect your PC to the network.
1. Go to the control panel (Start > Settings > Control Panel), and then double-click the
Network icon.
2. Select the network interface card used for the Ethernet interface you intend to use (e.g.,
TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button.
Depending on which version of Windows your PC is running, you may have to select
the “Local Area Connection” first, and then click on the “Properties” button to bring up
the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T
Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.
NOTE: Your network interface card will likely have a different name.
3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and
click on “Properties” to assign an IP address to your computer (this will disable “obtain
an IP address automatically”):
IP Address : 10.10.6.101
Netmask : 255.255.255.0
Default gateway : 10.10.6.1
4. Click or to exit the various dialog boxes.

5.2.3 Run the PINGME.C Demo
Connect a crossover cable from your computer’s Ethernet port to the OP6800’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 OP6800 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 or you are not using a straight-
through Ethernet cable.)
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 ping program:
ping 10.10.6.100
or by Start > Run
and typing the command
ping 10.10.6.100
Notice that the orange ACT light flashes on the OP6800 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.
5.2.4 Running More Demo Programs With a Direct Connection
The program SSI.C (SAMPLES\OP6800\TCPIP\) demonstrates how to make the
OP6800 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. LED0 and LED1
on the OP6800 (LED1 and LED2 on the Demonstration Board) will match those on the
Web page. As long as you have not modified the TCPCONFIG 1 macro in the sample pro-
gram, 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 LIB\TCPIP\TCP_CONFIG.LIB
library.
The sample program TELNET.C (SAMPLES\OP6800\TCPIP\) allows you to communi-
cate with the OP6800 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 IN00 (which is connected to
Demonstration Board switch SW1) to indicate that the TCP/IP connection should be
closed and high-current output OUT01 to indicate that there is an active connection.You
may change the digital input and output to suit your application needs.
Follow the instructions included in the sample program. Run the Telnet program on your
PC (Start > Run telnet 10.10.6.100). As long as you have not modified the TCP-
CONFIG 1 macro in the sample program, the IP address is 10.10.6.100 as shown; other-
wise 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.
User’s Manual 41
5.2.5 LCD/Keypad Sample Programs Showing TCP/IP Features
The following sample programs, found in the TCPIP subdirectory in
SAMPLES/LCD_Keypad/122x32_1x7, are targeted at the Ethernet-enabled versions of
the OP6800. Remember to configure the IP address, netmask, and gateway as indicated in
the sample programs.
MBOXDEMO.C—This program implements a web server that allows Web e-mail messages
to be entered that are then shown on the LCD display. The keypad allows you to scroll
within messages, flip to other e-mails, mark messages as read, and delete e-mails.
When a new e-mail arrives, an LED turns on, and turns off once the message has been
marked as read. A log of all e-mail actions is kept, and can be displayed in the Web
browser. All current e-mails can also be read with the Web browser.
When using MBOXDEMO.C, connect the OP6800 and a PC (or other device with a Web
Browser) to an Ethernet. If you connect the PC and the OP6800 directly, be sure to use
a crossover Ethernet cable; straight-through Ethernet cables and a hub may be used
instead.
TCP_RESPOND.C—This program and TCP_SEND.C are executed on two separate sin-
gle-board computers to demonstrate how the two boards communicate with each other.
Use PCSEND.EXE on the PC console side at the command prompt if you do not have a
second board. PCSEND.EXE is located with source code in the
SAMPLES/LCD_Keypad/Windows directory.
TCP_RESPOND.C waits for a message from another single-board computer. The mes-
sage received is displayed on the LCD, and you may respond by pressing a key on the
keypad. The response is then sent to the remote single-board computer.
TCPSEND.C—This program and TCP_RESPOND.C are executed on two separate single-
board computers to demonstrate how the two boards communicate with each other. Use
PCRESPOND.EXE on the PC console side at the command prompt if you do not have a
second board. PCRESPOND.EXE is located with source code in the
SAMPLES/LCD_Keypad/Windows directory.
When a key on the keypad is pressed, a message associated with that key is sent to a
specified destination address and port. The destination then responds to that message.
The response is displayed on the LCD.
Note that only the LEFT and UP scroll keys are set up to cause a message to be sent.
When using TCPSEND.C and TCP_RESPOND.C, connect the OP6800 and the other single-
board computer to an Ethernet. If you connect the them directly, be sure to use a crossover
Ethernet cable; straight-through Ethernet cables and a hub may be used instead.

6. INSTALLATION AND
MOUNTING GUIDELINES
Chapter 6 describes some considerations for mounting the
OP6800 in a panel, and includes detailed mounting instructions.
6.1 Installation Guidelines
When possible, following these guidelines when mounting an OP6800.
1. Leave sufficient ventilation space.
2. Do not install the OP6800 directly above machinery that radiates a lot of heat (for
example, heaters, transformers, and high-power resistors).
3. Leave at least 8" (20 cm) distance from electric power lines and even more from high-
voltage devices.
4. When installing the OP6800 near devices with strong electrical or magnetic fields (such
as solenoids), allow a least 3" (8 cm), more if necessary.
The OP6800 has strong environmental resistance and high reliability, but you can maxi-
mize system reliability by avoiding or eliminating the following conditions at the installa-
tion site.
Abrupt temperature changes and condensation
Ambient temperatures exceeding a range of 0°C to 50°C
Relative humidity exceeding a range of 5% to 95%
Strong magnetism or high voltage
Corrosive gasses
Direct vibration or shock
Excessive iron dust or salt
Spray from harsh chemicals
User’s Manual 45
6.2 Mounting Instructions
A bezel and a gasket are included with the OP6800. When properly mounted in a panel,
the bezel of the OP6800 is designed to meet NEMA 4 specifications for water resistance.
Since the OP6800 employs an LCD display, the viewing angle must be considered when
mounting the display. Install the OP6800 at a height and angle that makes it easy for the
operator to see the screen.
6.2.1 Bezel-Mount Installation
This section describes and illustrates how to bezel-mount the OP6800. Follow these steps
for bezel-mount installation.
1. Cut mounting holes in the mounting panel in accordance with the recommended dimen-
sions in Figure 20, then use the bezel faceplate to mount the OP6800 onto the panel.

2. Remove the standoffs added to the OP6800 as described in Chapter 2, “Getting
Started.” The standoffs were used to prop up the OP6800 beside the Demonstration
Board, and are not needed to mount the OP6800.
3. Carefully “drop in” the OP6800 with the bezel and gasket attached.

Carefully tighten the screws until the gasket is compressed and the plastic bezel face-
plate is touching the panel.
Do not tighten each screw fully before moving on to the next screw. Apply only one or
two turns to each screw in sequence until all are tightened manually as far as they can
be so that the gasket is compressed and the plastic bezel faceplate is touching the panel.

It is recommended that you allow for an “exclusion zone” of 0.25" (6 mm) around the
OP6800 in all directions when the OP6800 is incorporated into an assembly that includes
other components. This “exclusion zone” that you keep free of other components and
boards will allow for sufficient air flow, and will help to minimize any electrical or EMI
interference between adjacent boards. Figure A-2 shows this “exclusion zone.”

A.2 Conformal Coating
The areas around the crystal oscillator and the battery backup circuit on the OP6800 mod-
ule have had the Dow Corning silicone-based 1-2620 conformal coating applied. The con-
formally coated areas are shown in Figure A-3. The conformal coating protects these
high-impedance circuits from the effects of moisture and contaminants over time.

APPENDIX B. POWER SUPPLY
Appendix B describes the power circuitry provided on the
OP6800.
B.1 Power Supplies
Power is supplied to the OP6800 via pins 20 and 21 of header J1, which is connected by a
ribbon cable to either the Demonstration Board or to your system. The OP6800 is pro-
tected against reverse polarity by a diode at D6 as shown in Figure B-1.

Figure B-1. OP6800 Power Supply
The input voltage range is from 9 V to 36 V. A switching power regulator is used to pro-
vide a Vcc of +5 V for the OP6800 logic circuits. Vcc is not accessible to the user.
NOTE: In addition to supplying +RAW to the OP6800 switching power regulator, the
Demonstration Board has its own independent linear power regulator to supply the
electronics in the demonstration area of the Demonstration Board. See Appendix C for
more information.

B.2 Batteries and External Battery Connections
The SRAM and the real-time clock have provision for 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 OP6800 is powered or not. When the OP6800 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 and real-time clock power must
come from a backup battery in your system which you would connect to pin 40 of header J1
on the OP6800 via the ribbon cable. The backup battery should be able to supply 2.85 V–
3.15 V at 10 µA.
The reset generator circuit controls the source of power by way of its /RESET output signal.
B.2.1 Battery-Backup Circuit
Figure B-1 shows the battery-backup circuit located on the OP6800 module.

Figure B-1. OP6800 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 U6, 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 OP6800.
60 MiniCom (OP6800)
B.2.2 Power to VRAM Switch
The VRAM switch on the OP6800 module, shown in Figure B-1, allows the battery
backup to provide power when the external power goes off. The switch provides an isola-
tion between Vcc and the battery when Vcc goes low. This prevents the Vcc line from
draining the battery.

Figure B-1. VRAM Switch
Field-effect transistor Q5 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 OP6800 is not in reset, the /RESET line will be high. This turns on Q2, causing
its collector to go low. This turns on Q5, allowing VRAM to nearly equal Vcc.
When the OP6800 is in reset, the /RESET line will go low. This turns off Q2 and Q5, pro-
viding an isolation between Vcc and VRAM.
B.2.3 Reset Generator
The OP6800 module uses a reset generator on the module, U1, 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.

Figure B-1. Chip Select Circuit
The current drain on the battery in a battery-backed circuit must be kept at a minimum.
When the OP6800 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 (R28). This pullup resistor keeps /CSRAM at the VRAM voltage
level (which under no power condition is the backup battery’s regulated voltage at a little
more than 2 V).
Transistors Q3 and Q4 are of opposite polarity so that a rail-to-rail voltage can be passed.
When the /CS1 voltage is low, Q3 will conduct. When the /CS1 voltage is high, Q4 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.

C.2 Power Supply
The OP6800 requires an unregulated +RAW power input of 9 V to 36 V DC, which can be
supplied from the Demonstration Board through the ribbon cable connection. The OP6800
has its own switching voltage regulator.
Figure C-2 shows the distribution of the +RAW input power to the OP6800 through the
Demonstration Board. The reference grounds on the OP6800, GND, and on the Demon-
stration Board, 0 V, are tied together at one connection point only to avoid creating a
ground loop, which could lead to considerable electromagnetic interference.

The Demonstration Board has an onboard LM7805 linear regulator for the circuits on the
Demonstration Board only. Its major drawback is its inefficiency, which is directly propor-
tional to the voltage drop across it. The voltage drop creates heat and wastes power.
You may wish to use a switching power supply in your applications where better effi-
ciency is desirable. The LM2575 is an example of an easy-to-use switching voltage regu-
lator. This part greatly reduces the heat dissipation of the regulator. The drawback in using
a switching voltage regulator is its higher cost.

Figure C-3. Demonstration Board Power Supply
Capacitor C1 provides surge current protection for the voltage regulator, and allows the
external power supply to be located some distance away.
Be careful to limit the current draw in any prototype circuits you build on the prototyping
area of the Demonstration Board to avoid operating the linear regulator outside its recom-
mended limits. The LEDs and buzzer together can draw up to 70 mA, which still leaves
some current capacity for your own circuits (see Table C-1) if you plan to use them with
the LEDs and the buzzer.
If you need additional current from the linear regulator beyond that specified in Table C-1,
consider adding a heat sink to the linear regulator (remember to use silicone grease
between the tab and the heat sink), or use a lower voltage power supply.

C.3 Using the Demonstration Board
The Demonstration Board is actually both a demonstration board and a prototyping board.
As a demonstration board, it can be used to demonstrate the functionality of the OP6800
right out of the box without any modifications to either board. There are no jumpers or dip
switches to configure or misconfigure on the Demonstration Board so that the initial setup
is very straightforward.
The Demonstration Board comes with the basic components necessary to demonstrate the
operation of the OP6800. Four LEDs (DS1–DS4) are connected to OUT07–OUT10, and
four switches (S1–S4) are connected to IN00–IN03 to demonstrate the interface to the
OP6800.
The Demonstration Board has a buzzer that is normally off. The buzzer can be enabled to
be on by setting the jumper across pins 1–2 on header JP1 on the Demonstration Board as
shown in Figure C-4. When enabled on, the buzzer will sound whenever the OUT0 digital
output on the OP6800 is on.

User’s Manual 73
D.3 Serial Communication (OP68xx.LIB)
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. For more information, see the Dynamic C User’s Manual and Technical
Note TN213, Rabbit 2000 Serial Port Software.
Use the following function calls with the OP6800.
int serMode(int mode);
User interface to set up OP6800 serial communication lines. Call this function after serXOpen().
Whether you are opening one or multiple serial ports, this function must be executed after executing the last
serXOpen function AND before you start using any of the serial ports. This function is non-reentrant.
If Mode 1 is selected, CTS/RTS flow control is exercised using the serCflowcontrolOn and
serCflowcontrolOff functions from the RS232.LIB library.
PARAMETER
mode is the defined serial port configuration
.

What they say about us
FANTASTIC RESOURCE
One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!
Bucher Emhart Glass
EXCELLENT SERVICE
With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.
Fuji
HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
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.
Trican Well Service
GO TO SOURCE
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.
