   |     Note: A total of 127 base address settings are         |
   |     available. 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)|
