background informa- tion on the SBC-410. Sections include: • Card specifications • Board layout Chapter 1 General Information 1 CHAPTER Introduction The SBC-410 is an all-in-one CPU card that supports L2 cache sizes from 128 KB to 512 KB (32 KB x 8, 64 KB x 8, or 128 KB x 8). This CPU card uses the M1489/M1487 chipsets, which accept Intel, AMD, Cyrix, or other compatible 486-based CPUs. The SBC- 410 is fully PC/AT compatible, so your software will run without modifications. On-board features include two high-speed serial ports (RS-232 and RS-232/422/485) with 16C550 UARTs, one bi-directional parallel port, and a floppy drive controller. If program execution is halted by a program bug or EMI, the board's 15-stage watchdog timer can automatically reset the CPU or generate an interrupt. This ensures reliability in unmanned or stand-alone systems. The SBC-410 is built with two high speed local bus Enhanced IDE controllers. This controller supports (through ATA PIO) mode 3 and mode 4 hard disks, which enable data transfer rates of over 11 MB/ second. It connects up to four IDE devices, including large hard disks, CD-ROM drives, tape backup drives, etc. The built-in enhanced IDE controller provides a 4-layer 32-bit posted write-buffer and a 4-layer 32- bit read-prefetch-buffer to boost IDE performance. The SBC-410 supports 5V EDO DRAM. It also provides two 72-pin SIMM (Single In-line Memory Module) sockets for on-board DRAM. This gives you the flexibility to configure your system memory from 1 ~ 64 MB using the most economical combination of SIMMs. The SBC-410 also features power management to minimize power consumption. It uses CMOS components and complies with the "Green Function" standard. If you need any additional functions, you can add industry-standard PC/104 expansion modules. We provide numerous PC/104 modules to meet your system requirements. 2 SBC-410 User's Manual Features • Accepts any Intel, AMD, Cyrix, or other compatible processor • Half-size ISA bus CPU card, fully 486SX/DX/DX2/DX4/5x86/Pentium Over Drive compatible • Built-in 128 KB secondary cache, up to 512 KB • Up to 64 MB of on-board DRAM; supports 5V EDO DRAM • Built-in IDE (AT bus) hard disk drive interface, floppy drive controller • One RS-232 and one RS-232/422/485 selectable serial port; uses 16C550 UARTs with 16-byte FIFO • One bi-directional parallel port o o • 32 to 140 F (0 to 60 C) operating temperature • Watchdog timer, software programmable from 2 to 32 seconds (15 steps, 2 seconds per step) • On-board keyboard connector and/or PS/2 mouse • IDE HDD auto-detection • Connectors for PC/104 module expansion • Single +5V power supply • "Green" function, supports power management Chapter 1 General Information 3 Specifications • CPU: Intel 486SX/DX/DX2/DX4/Pentium Over Drive; AMD Am486DX/DX2/DX4/5x86; IBM/SGS/Cyrix Cx486DX/DX2/M7/5x86; TI 486DX2/DX4 • Bus interface: ISA (PC/AT) bus • Data bus: 32 bit • Processing ability: 32 bit • Chipset: ALI 1489/1487 • RAM memory: 1 MB to 64 MB, two 72-pin sockets • Shadow RAM memory: Supports system and video BIOS up to 256 KB in 32 KB blocks • L2 Cache memory: On-board 128 KB, up to 512 KB (DIP package) • Enhanced IDE HDD interface: Supports up to four enhanced IDE (ATA-2 bus) large hard disk drives or other enhanced IDE devices.

A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper you connect the pins with the clip. To "open" a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2 or 2 and 3. 3 2 1 Open Closed Closed 2-3 The jumper settings are schematically depicted in this manual as follows: 1 2 3 Open Closed Closed 2-3 A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales represen- tative before you make any changes. Generally, you simply need a standard cable to make most connections. 12 SBC-410 User's Manual Safety Precantions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on, sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Installing the CPU The SBC-410 CPU card supports most 486 CPUs. The system's performance depends on the CPU you choose. You can install or upgrade the CPU in the board's PGA socket by following the procedures outlined below. If your system has an existing CPU, you need to remove it before installing the new CPU. Removing a CPU 1. Disconnect power from the chassis, and unplug all connec- tions to the CPU card. Then, remove the CPU card from the chassis by following the instructions in the user's manual for your chassis. 2. Lift the CPU out of the PGA socket. The old chip may be difficult to remove. You may find spray chip lubricant, designed for pin-grid-array (PGA) devices, and a chip puller helpful. These are available at electronics hobbyists' supply stores. Chapter 2 Installation 13 Installing a CPU To install the CPU, follow the instructions that came with it. If no documentation is provided, the general procedure for installing a CPU are outlined below: 1. Lubricate the pins on the CPU with lubricant for PGA devices. This makes the CPU slide in much easier and greatly reduces the chance of damaging the pins and other components. 2. Carefully align the CPU so that it is parallel to the socket. Make sure that the notch on the corner of the CPU matches the notch on the inside of the socket. 3. Gently push the CPU into the socket. There will probably be a small gap between the CPU and the socket even when it is fully seated. DO NOT USE EXCESSIVE FORCE! When you install a new CPU, you may have to adjust other settings on the board, such as CPU type, CPU clock and PCI speed, to accommodate it. Make sure that the settings are correct for your CPU. Improper settings may damage the CPU. 14 SBC-410 User's Manual CPU type select (JP1, JP2, JP3) JP1, JP2, and JP3 must be set to match the CPU type.

When installing SIMMs, make sure that Bank 1 is filled first. Installing SIMMs Note that the modules can only fit into a socket one way. 1. Insert the memory module into the socket at a moderate angle. 2. Push the module toward the vertical posts at both ends of the socket until the module is upright, and the retaining clips at both ends of the module click into place. When positioned correctly, the pins on top of the vertical posts should corre- spond to the circular holes on the ends of the module. 3. Repeat steps 1 and 2 for each module you install. Removing SIMMs If you need to remove a SIMM, follow the procedures below: 1. Supporting the SIMM with a finger, use a pen or a similarly shaped object and press one retaining clip straight down. 2. Repeat for the other side. When released, the retaining clips will push the SIMM up and out of its upright position. 3. Carefully pull the SIMM out of the socket with your fingers. 4. Repeat the above steps for each module you remove. Chapter 2 Installation 17 Selecting cache memory size The SBC-410 features a 2nd level memory cache that supports 128, 256, or 512 KB of cache memory. Higher cache memory can improve your system's performance. The cache uses SRAM chips in three sizes: 32 KB, 64 KB and 128 KB. The on-board cache memory banks consists of four SRAM chip sockets, each of which accepts one "Tag" chip. All SRAM chips must have a speed of 20 ns or faster. The table below shows the possible cache configurations: Cache Configuration Cache size Tag RAM Data RAM 128 KB one 32 K x 8 four 32 KB x 8 SRAMs 256 KB one 32 K x 8 four 64 KB x 8 SRAMs 512 KB one 32 K x 8 four 128 K x 8 SRAMs Cache memory select (JP11) When the cache size changes, you must make sure that JP11 is set to match the new cache memory size.

The card comes with a 40-pin and a 44-pin flat-cable piggyback cables. The 40-pin flat-cable has three identical 40-pin connectors. Connecting the hard drive Wire number 1 on the cable is red or blue, and the other wires are gray. 1. Connect one end of the cable to Primary IDE or Secondary IDE on the CPU card. Make sure that the red (or blue) wire corresponds to pin 1 on the connector, which is labeled on the board (on the right side). 2. Plug the other end of the cable to the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drive. (See your hard drive's documentation for the location of the connector.) Unlike floppy drives, you can make the connections with any of the connectors on the cable. If you install two drives, you will need to set one as the master and one as the slave. You do this using jumpers on the drives. If you install just one drive, set it as the master.

Using the BIOS Peripheral Setup program, you can select the address for each port or disable it. The card mounting bracket has two serial port connectors. The DB-9 connector on the top of the bracket is COMA, the RS-232 serial port. The DB-9 connector on the bottom of the bracket is COMB, the RS-232/422/485 serial port. RS-232/422/485 select for COMB (JP12, JP13, JP14, JP15, JP16) RS-232 serial ports are widely used for external input/output devices. The RS-422 and RS-485, however, are popular for industrial and laboratory applications because they offer high noise resistance and long range communication (up to 4000 ft, 1200 m). The RS-422 is commnly used for two-way communica- tion between two devices, where as RS-485 is used for communi- cation between a single master and a network of slave modules. COMA is the RS-232 serial port, and COMB can function as an RS-232, RS-422, or RS-485, depending on the jumper settings from JP12, JP13, JP14, JP15 and JP16. To select the desired serial port type for COMB, adjust JP12, JP13, JP14, JP15, and JP16: RS-232/422/485 select for COMB (JP12, JP13, JP14, JP15, JP16) JP12 1 1 RS-232* 5 3 JP12 1 1 RS-422 5 3 JP12 1 1 RS-485 5 3 *default 26 SBC-410 User's Manual JP13 JP13 JP13 JP14 JP14 JP14 JP15 JP15 JP15 JP16 JP16 JP16 RS-232/422/485 serial port connections (COMA, COMB) Pin assignments The following table shows the pin assignments for the card's RS-232 and RS-422/485 (COMB) serial port connectors: RS-232 (COMA, COMB) RS-422/485 (COMB) Pin Signal Pin Signal 1 DCD 1 TX- (DTE) 2 RX 2 TX+ (DTE) 3 TX 3 RX+ (DTE) 4 DTR 4 RX- (DTE) 5 GND 5 Ground 6 DSR 6 RTS- 7 RTS 7 RTS+ 8 CTS 8 CTS- 9 RI 9 CTS- Chapter 2 Installation 27 RS-422 signal wiring RS-422 is used for long-distance point-to-point connections. RS- 422 originally used four wires for one-way communication (with devices such as display terminals or printer) but was later adopted by the industry for simultaneous two-way communication by doubling the number of wires. Each pin on the first device connects to a corresponding device on the second. Flow control lines manage the communication. The following table shows pin connections. Computer A Computer B Pin Signal Pin Signal 1 TX- > 4 RX- 2 TX+ > 3 RX+ 3 RX+ < 2 TX+ 4 RX- < 1 TX- 5 Ground < 5 Ground 6 RTS- > 9 CTS- 7 RTS+ > 8 CTS+ 8 CTS+ < 7 RTS+ 9 CTS- < 6 RTS- RS-485 signal wiring In a typical RS-485 application, the host device requests data from a slave module then listens for the response. The host transmits and receives data on the same pair of wires. Software handles the flow control; no other wires are needed. Pin assignments appear in the following table. Pins 1 and 4 share the Data- wire. Pins 2 and 3 share the Data+ wire.

Watchdog timer time-out signal select (JP4) Reset CPU* IRQ15 1 2 3 1 2 3 * default Watchdog timer programming The watchdog timer must be programmed to write to I/O port address 443 at an interval shorter than the timer's preset interval. The timer's interval has a tolerance of ±5%, so you should program an instruction that will refresh the timer before a time- out occurs. The following steps illustrate how you might program the watchdog timer. Chapter 2 Installation 29 1. Write to I/O port 443 (Hex) and designate a time-out interval. This will enable the watchdog and set up its time-out interval. 2. Write to I/O port 080 (Hex) and any random value. This will in turn disable the watchdog timer. The watchdog timer-out interval can be set at 15 levels between 2 and 32 seconds.

Appendix B Installing PC/104 Modules 67 APPENDIX Installing PC/104 modules The SBC-410's PC/104 connectors give you the flexibility to attach PC/104 expansion modules. These modules perform the functions of traditional plug-in expansion cards, but save space and valuable slots. Modules include: • PCM-3600 FAX/Modem Module • PCM-3420 Fast SCSI-2 Module • PCM-3200 Sound Module • PCM-3810 Solid State Disk Module • PCM-3820 High Density Flash Disk Module • PCM-3115 PCMCIA Module (two slots) • PCM-3610 Isolated RS-232 and RS-422/485 Module • PCM-3660 Ethernet Module • PCM-3718 30 KHz A/D Module • PCM-3724 48-channel DIO Module • PCM-3910 Breadboard Module To install these modules on the SBC-400 is a quick and simple operation. The following steps show how to mount the PC/104 modules: Step 1 Remove the SBC-410 from your system paying particular attention to the safety instructions already mentioned above. Step 2 Make any jumper or link changes required to the CPU card now. Once the PC/104 module is mounted you may have difficulty in accessing these. Step 3 Normal PC/104 modules have "male" connectors and mount directly onto the main card. However, for reasons that ensure better bus matching, the connectors on the SBC-410 and the PC/104 module are both "female". For this reason you need to plug- in a "male-male" adapter connecter (included with the SBC-410). Please refer to the following PC/104 module mounting diagram on the following page. After this is in place you then have the correct mounting connector to accept your PC/104 module. 68 SBC-410 User's Manual Step 4 Mount the PC/104 module onto the CPU card. Do this by pressing the module firmly but carefully onto the mounting connectors. Step 5 Secure the PC/104 module onto the CPU card using the four mounting spacers and srews.
