A total of 16 board address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/B is the Most Significant Bit and switch SW1/E is the Least Significant Bit. The switches have the following decimal values: SW1/B=8, SW1/C=4, SW1/D=2, SW1/E=1. Turn on the switches and add the values of the switches to obtain the correct board number. (Off=0, On=1)
