The table below provides the DIP-Switch settings for
valid base I/O addresses of the ISI551PC. The
switches can be set to "OPEN" (
O
in the table below)
or to "CLOSED" (C in the table below). Holding the
board with the switch facing you (reading numbers
1-8 left to right), the "UP" position for the switch is
OPEN, and the "DOWN" position is CLOSED. "S1"
below is labeled as "1" on the left side of the switch
and so on, through S8. For an example, turn to page
A-3 and compare the default switch settings (2F8)
with the address 380h listing.
