Power LED and keylock connector
(CN2)
You can connect an LED to indicate when the CPU card is on. Pin 1
of CN2 supplies power to the LED; Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard. In this
state, the PC will not respond to any input. This is useful if you do
not want anyone to change or stop a running program. Simply
connect the switch between Pins 4 and 5. The pin assignments
appear in the following table:
