DS1 Switch Settings—I/O Port Address
The factory set I/O port address (hexadecimal) is 100h. (The h is used to denote a hexadecimal number.)
The Dual In-line Package (DIP) switch designated DS1, SW11 through SW9 selects the port address of the output ports. The address must be set such that it does not conflict with other I/O addresses in the PC system. This address must also be consistent with the software being used. Figure A-3 shows switch DS1, SW11 through SW9 with the I/O address set to the factory setting (100h).
