16 PCA-6155 User's Manual
Power LED and Keylock (CN5)
You can use a LED to indicate when the CPU card is on. Pin 1 of
CN5 supplies the LED's power, and Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard so the PC
will not respond to any input. This is useful if you don't want
anyone to change or stop a running program. Connect the switch
between Pins 4 and 5 of CN5.

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.
Wire number 1 on the cable is red or blue, the other wires are gray.
Connect one end to CN6 or CN7 on the CPU card. Make sure that
the red (or blue) wire corresponds to pin 1 on the connector (on the
right side). See Chapter 1 for help finding the connector.
