2.4 Jumper and DIP Switch Description
You can change the ACL8112'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 your own
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 your own
PC. Please check your PC before installing the ACL-8112.
The ACL-8112's base address of registers is selected by an 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. You may modify
the base address if the address HEX 220 has been occupied by another add-
on card.
