2.4 Jumper and DIP Switch Description

ACL8112's channels and base address can be changed by setting jumpers
and DIP switches on the card. The card's jumpers and switches are preset at
the factory. The jumper settings can be changed for the user’s applications.

A jumper switch is closed (sometimes referred to as "shorted") with the
plastic cap inserted over two pins of the jumper. A jumper is open when the
plastic cap is inserted over one or no pin(s) of the jumper.

2.5 Base Address Setting

The ACL-8112 requires 16 consecutive address locations in the I/O address
space. The base address of the ACL-8112 is restricted by the following
conditions.

1. The base address must be within the range Hex 200 to Hex 3FF.

2. The base address should not conflict with any PC reserved I/O

address. See Appendix A.

3. The base address must not conflict with any add-on card on the

user’s PC. Please check your PC before installing the ACL-8112.

The ACL-8112's base address of registers is selected by a 6-positions DIP
switch SW1. The default setting of base address is set to be HEX 220. All
possible base address combinations are listed as Table 2.2. The base
address may be modified if the address HEX 220 has been occupied by
another add-on card.
