2.4 Jumper and DIP Switch Description

You can change the ACL-8316/12's channels and the base address by

setting jumpers and DIP switches on the card. The card's jumpers and

switches are preset at the factory. You can change the jumper settings for

plastic cap inserted over one or no pin(s) of the jumper.
