Setting the I/O Base Address
I/O base addresses are areas of memory that your CPU uses to distinguish
between the various peripheral devices connected to your system when
transferring or receiving data. This card uses a single DIP switch bank (SW1), as
shown in the card illustration below, to assign the card’s base address. The
illustration shows the switch settings for an I/O base address of 380.

Procedure
To set the I/O base address switches:
1. Determine the appropriate I/O base address for the card. You may use the
utility feature for obtaining a list of unused addresses. See
2. Identify the switch settings for the address selected. Appendix D provides a
list of switch settings for possible addresses.
3. Set the switches to the desired address. A switch in the up or On position
represents a binary 1. A switch in the down or Off position represents a
binary 0.
