1)

 :

5V TTL signals from serial I/O controller

2)

 :

Termination of USB lines on CPU. The +5V and GND signals need fuses and inductors for
decoupling (USB specification).

3)

 :

The 5V LPT signals need decoupling and pull-up resistors near the backplane LPT␣ 1
connector.

4)

 :

5V open collector signal (5V/100mA)

5)

 :

Option “External Battery” (Note: battery must be removed from CPU board)
U

bat

 = +3.4V to +3.6V

6)

 :

RS485 signals
