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.
