  • Page 17: Jumpers And Connectors

    Connectors on the board link it to external devices such as hard disk drives, a keyboard or floppy drives. In addition, the board has a number of jumpers that allow you to configure your system to suit your application. The table below lists the function of each of the board jumpers and connectors.

  • Page 19: Setting Jumpers

    You configure your card to match the needs of your application by setting jumpers. 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”...
  • Page 20 The SBC-400 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.

  • Page 21: Installing A Cpu

    To install the CPU, follow the instructions that came with it. If no documentation was 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.

  • Page 24: Installing Simms

    The SBC-400 CPU card provides two 72-pin SIMM (Single In-line Memory Module) sockets and supports between 1 MB to 128 MB of RAM. When installing SIMMs, make sure that Bank 1 is filled first. Note that the modules can only fit into a socket one way.
  • Page 25 3. Carefully pull the SIMM out of the socket with your fingers. 4. Repeat the above steps for each module you remove. The SBC-400 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.
  • Page 26 You can attach two Enhanced Integrated Device Electronics hard disk drives to the SBC-400's internal controller. The card comes with a 40-pin flat-cable piggyback cable. This cable has three identical 40-pin flat-cable connectors. Wire number 1 on the cable is red or blue, and the other wires are gray.
  • Page 27 jumpers on the drives. If you install just one drive, set it as the master. The following table lists the pin numbers and their respective signals: Signal Signal Reset N.C. N.C, IORDY BALE N.C. -I/O CS16 N.C.
  • Page 28 -ACT You can attach up to two floppy disks to the SBC-400's on-board controller. You can use any combination of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720 KB, 1.44 MB, and 2.88 MB) drives. The SBC-400 CPU card comes with a 34-pin daisy-chain drive connector cable.
  • Page 29 Disk change Normally, the parallel port is used to connect the card to a printer. The SBC-400 includes an on-board parallel port, CN3, which is accessed through a 26-pin flat-cable connector. The CPU card comes with an adapter cable, which lets you use a traditional DB- 25 connector.
  • Page 30 Busy Paper empty + Select - Auto feed - Error - Init printer - Select input 18~25 You can select the parallel port DRQ and DACK by setting JP10 and JP11, respectively. The following charts show the available options.
  • Page 31 JP10 JP11 JP11 In single-board-computer (non-passive-backplane) applications you will need to connect power directly to the SBC-400 board using CN4. This connector is fully compatible with the standard PC power supply connector. See the following table for its pin assignments: Function N.C.
  • Page 32 +12 V -12 V The SBC-400 board provides two keyboard connectors. A 5-pin connector (CN7) supports passive backplane applications. A second 6-pin mini-DIN connector (J1) on the card mounting bracket supports single-board-computer applications. The card comes with an adapter to convert the 6-pin mini-DIN connector, used for the mouse, to the standard DIN connector for the key- board.

  • Page 33: Serial Ports

    +5 V K.B. clock PS/2 mouse clock The SBC-400 offers two serial ports: one RS-232 and one RS-232/ 422/485. 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.

  • Page 37 IRQ11 IRQ12 IRQ12 IRQ11 If CPU processing comes to a halt because of EMI or software bug, the watchdog timer can either reset the CPU or signal an interrupt on IRQ15. Reset CPU IRQ15 The watchdog timer must be programmed to write to I/O port address 443 at an interval shorter than the timer's preset interval.
  • Page 38 The following steps illustrate how you might program the watch- dog timer. 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 043 (Hex) and any random value. This will in turn disable the watchdog timer.
