ISA Host Adapters
Setting the I/O Port Address
The ISA EPC/X host adapter uses four bytes of address space on the host computer’s I/O bus. Before installing the
host adapter, the board’s I/O port starting address must be set on DIP switch SW1 (located on the top of the board).
To insure flexibility, seven I/O port address ranges are available: 108h-10Bh, 118h-11Bh, 128h-12Bh, 208h-20Bh,
228h-22Bh, 308h-30Bh and 328h-32Bh. Choose one of the starting addresses and set SW1-1, 2 and 3 as shown in
Figure 12 below.

the device driver.
