2.4 Base Address Setting
The ACL-8111 requires 16 consecutive address locations in I/O
address space. The base address of the ACL-8111 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-
8111.
The ACL-8111's base address is selected by a 6 position 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.
