   |      Note: A total of 4095 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 SW2/6 is the Least         |
   |      Significant Bit. The switches have the following      |
   |      decimal values: SW1/1=131072, SW1/2=65536,            |
   |      SW1/3=32768, SW1/4=16384, SW1/5=8192, SW1/6=4096,     |
   |      SW1/7=2048, SW1/8=1024, SW2/1=512, SW2/2=256,         |
   |      SW2/3=128, SW2/4=64, SW2/5=32, SW2/6=16. Turn off the |
   |      switches and add the values of the switches that are  |
   |      off to obtain the correct memory address. (Off=1,     |
   |      On=0)                                                 |
