2.4 Jumper and DIP Switch Description
The ACL-7120A channels and base addresses can be changed through
jumper settings and DIP switches on the card. The ACL-7120A is pre-
configured at the factory and should not need to be changed under normal
circumstances.
A jumper switch is closed or "shorted" with the plastic cap inserted over two
pins of the jumper. A jumper is open when the plastic cap inserted over one
or no pin(s) of the jumper.
