The switches are a binary representation of the decimal memory addresses. SW1/1 is the Most Significant Bit and switch SW1/7 is the Least Significant Bit. The switches have the following decimal values: SW1/1=512, SW1/2=256, SW1/3=128, SW1/4=64, SW1/5=32, SW1/6=16, SW1/7=8. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0) SW1/10 must always be on.

The function of SW2 is to configure port 1. The functions of switches SW3 through SW5 are to configure ports 2 through 4 respectively. A total of 128 base address settings are available. The switches are a binary representation of the decimal memory addresses. SWx/1 is the Most Significant Bit and switch SWx/7 is the Least Significant Bit. The switches have the following decimal values: SWx/1=512, SWx/2=256, SWx/3=128, SWx/4=64, SWx/5=32, SWx/6=16, SWx/7=8.

Up to four boards may be daisy-chained. Daisy-chaining boards to operate as one unit will only function under MS-DOS and compatible operating systems. MISCELLANEOUS TECHNICAL NOTE When using non-MS-DOS compatible operating systems, each board should be configured as a separate unit with different interrupts and I/O addresses.
