  • Page 9 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” a jumper you connect the pins with the clip.

  • Page 15: Chapter 3 Connecting Peripherals

    You can attach up to two floppy disk drives to the PCA-6143P's on-board controller. You can use any combination of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720 KB and 1.44 MB) drives. The card comes with a 34-pin daisy-chain drive connector cable.
  • Page 16 You can attach two IDE (Integrated Device Electronics) hard disk drives to the PCA-6143P'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, the other wires are gray.
  • Page 17 Chapter 1 (page 5). The pin assignments for the connector appear in Appendix D. The PCA-6143P board provides two keyboard connectors. A 5-pin connector (J1) supports passive backplane applications. A second 6-pin mini-DIN connector (J3) on the card mounting bracket supports single-board-computer applications.
  • Page 18 JP12 is open. When jumper JP12 is closed, the CPU is fixed in Turbo mode. To switch into Turbo mode from the keyboard simultaneously press the Ctrl, Alt and keypad plus (+) keys. To switch into non-Turbo mode press the Ctrl, Alt and keypad minus (-) keys. PCA-6143P User's Manual...
  • Page 19 3Speaker out 4Speaker out In single-board-computer (non-passive-backplane) applications you will need to connect power directly to the PCA-6143P board using connector J2. This connector is fully compatible with the standard PC power supply connector for a 3.5" FDD (or HDD).
  • Page 20 The PCA-6143P offers two serial ports: one RS-232 and one RS-232/422/485. These ports let you connect to serial devices (a mouse, printers, etc.) or a communication network. You can select the address for each port (3F8H [COM1], 2F8H [COM2] or 3E8H) or disable it, through the BIOS Advanced Setup program, covered in Chapter 5.
  • Page 21 RS-422 is commonly used for two-way communication between two devices, whereas RS-485 is used for communication between a single master and a network of slave modules. Before you use the RS-232/422/485 port, you will need to select RS-232, RS-422 (the default) or RS-485 mode.

  • Page 39 Appendix A Flash/ROM disk 39...
  • Page 40 The PCA-6143P features an internal Flash/ROM disk drive. This drive emulates a floppy disk drive by using solid-state memory chips (Flash or EPROM) to store programs and data instead of the magnetic particles on the mechanical drive’s disk. The Flash/ROM disk offers much faster access times than a floppy or hard disk and greatly increased reliability in harsh environments.

  • Page 41: Appendix A Flash/Rom Disk

    The size of the emulated drive depends on the size and number of the chips you install. For example, if you install three 512 KB chips, you will have 3 x 512 KB = 1.536 MB, equivalent to a 1.44 MB floppy.

  • Page 43 Floppy disks The Flash/ROM disk will replace the corresponding floppy disk. For example, if you have a single floppy disk (drive A:) and assign the Flash/ROM disk to be the 1st drive (both switches 5 and 6 are on), any drive operations directed at drive A: will go to the Flash/ ROM disk.
  • Page 44 The next time you start the system, it will boot from the solid state disk. After you’ve set all the jumpers and switches on the PCA-6143P, insert the appropriate memory devices into the card’s sockets. Remember that you will need to program EPROMs before you insert them.
  • Page 45 If you use Flash memory or SRAM, it is advisable to format the Flash/SRAM disk before copying files to it. The DOS command is as follows: FORMAT drv: /U ... where drv = solid state disk drive A, B, C etc. The utility program COOKROM.EXE, included on the card's utility disk, splits the files on a diskette into a series of binary files.
