Chapter 2 Connecting peripherals 29
Power LED and Keylock (CN6)
You can use a LED to indicate when the CPU card is on. Pin 1
of CN6 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 do not
want anyone to change or stop running a program. Connect the
switch between Pins 4 and 5 of CN6.
