To install at another address, follow the procedure below.

1.

Select the address. Using an I/O port usage table (one is
included in Appendix A) select an unused hex address
space. Note that the card occupies 16 bytes of I/O space.
Use caution when selecting a port address. It is very
important that nothing else is installed at the selected
address.

2.

Convert the hex address to its binary equivalent.

3.

Throw away the 4 least significant bits.

4.

The remaining 7 digits represent the switch address. 1's
represent an OFF switch. 0's represent an ON switch.
