APPENDIX A

I/O ADDRESS SETTINGS

Each channel of the Fastcom: 232/8-ISA requires 8 contiguous bytes of address space. Since channels 2-8 are
addressed as offsets of the base address, you will need 64 contiguous bytes (040 hex) of address space. The
following are I/O addresses and devices that are typically assigned to them. You may use any I/O address that is
not used by a device installed in your system.
