Connecting Peripherals This chapter tells how to connect periph- erals, switches and indicators to the PCA- 6155 board. You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connec-...

Reset Switch (CN1) You can connect an external switch to easily reset your computer. This switch restarts your computer as if you had turned off the power, then turned it back on. Hard Drive LED (CN2) You can connect a LED to connector CN2 to indicate when the HDD is active.
Enhanced IDE (CN6, CN7) You can attach four IDE (Integrated Device Electronics) drives to the PCA-6155's internal controller. The PCA-6155 CPU card has two EIDE connectors, CN6 and CN7. The first two IDE devices must be installed into CN6. CN7 may be used for a third and fourth IDE device.
Floppy Drive (CN8) You can attach up to two floppy disk drives to the PCA-6155's on- board controller. You can use any combination of 5¼" (360 KB and 1.2 MB) and 3½" (720 KB and 1.44 MB) drives. The card comes with a 34-pin daisy-chain drive connector cable.
Serial Ports (CN11, CN12) The PCA-6155 offers two RS-232 serial ports, COM1 and COM2, which let you connect to serial devices (a mouse, printers, etc.) or a communication network. CN11 is COM1, and CN12 is COM2. See Chapter 1 for help finding the connectors.
