To install the bracket, find an empty slot in your chassis. Unscrew the
plate that covers the end of the slot. Screw in the bracket in place of
the plate. Next, attach the flat-cable connector to CN3 on the CPU
card. Wire 1 of the cable is red or blue, and the other wires are gray.
Make sure that wire 1 corresponds to pin 1 of CN3. Pin 1 is on the
right side of CN3.

Keyboard & PS/2 Mouse Connector (CN15)
The PCA-6154/6154L board provides a keyboard connector. A 6-pin
mini-DIN connector (CN15) on the card mounting bracket supports
single-board computer applications. The card comes with an adapter
to convert from the 6-pin mini-DIN connector to a standard DIN
connector and to a PS/2 mouse connector.

Front Panel Connector (CN16)
Next, you may want to install external switches to monitor and control
the PCA-6154/6154L. These features are optional - install them only
if you need them. The front panel connector (CN16) is a 14-pin male,
dual in-line header and provides connections for a speaker, hard disk
access indicator, power on indicator, turbo indicator and an input
switch for resetting the card.
LED interface
The front panel LED indicator for power on is an active high signal.
Reset switch
If you install a reset switch, it should be a open single pole switch.
Momentarily pressing the switch will activate a reset. The switch
should be rated for 10 mA, 5 V.
If you need to make your own cable, you can find the pin assignments
for the card’s connector in Appendix C.
