IrDA Tx/Rx Header (IR CON)

receiving infrared modules. This module mounts on to a small

Power LED and Keyboard LOCK
(KEYLOCK)
You can use a LED to indicate that the CPU card is on. Pin 1 of
KEYLOCK is the LED's power, and Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard so that the
PC will not respond to any input. This is useful if you do not want
anyone to change or stop a running program. Connect the switch
between Pins 4 and 5 of KEYLOCK.
