and a DB-25 connector on the other, mounted on a retaining
bracket. The bracket installs at the end of an empty slot in your
chassis, giving you access to the connector.
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 connec-
tor CN3 on the CPU card. Wire one of the cable is red or blue, the
other wires are gray. Make sure that wire one connects to pin one
of CN3. Pin one is on the right side of CN3. For help finding the
connector, refer to 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. The card comes with
an adapter to convert from the 6-pin mini-DIN connector to a
standard DIN connector.
If you need to make your own adapter cable, you can find the pin
assignments in Appendix D.
Next you may want to install external switches to monitor and
control your CPU card. These features are completely optional —
install them only if you need them.
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. Install the switch so that it closes the
two pins of JP7 when pressed (normally-open switch).
