   | 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) |
