   |     Note:A total of 255 base address settings are          |
   |     available. The switches are a binary representation of |
   |     the decimal memory addresses. SW1/8 is the Most        |
   |     Significant Bit and switch SW1/1 is the Least          |
   |     Significant Bit. The switches have the following       |
   |     decimal values: SW1/8=512, SW1/7=256, SW1/6=128,       |
   |     SW1/5=64, SW1/4=32, SW1/3=16, SW1/2=8, SW1/1=4. Turn   |
   |     off the switches and add the values of the switches to |
   |     obtain the correct memory address. (Off=0, On=1)       |
