D.2 Installation
(1) I/O address settings
SW1 and SW2 are the switches selecting the ISA bus I/O addresses. SW1 numbers 1 to 8 correspond to ISA
bus addresses A4 to A11, and SW2 numbers 1 to 4 correspond to ISA bus addresses A12 to A15.
In the IE-78K0-NS, the addresses should be set between 020×H and 03F×H. The switch takes the value "0"
when ON and "1" when OFF.
The addresses used for setup must be values that are not used in the PC system or for other boards. In
addition, since these values are used during software installation, make a note of them for future reference.
Setting examples of I/O address, SW1 and SW2 are shown below.
