   |  Note: A total of 255 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 SW1/8 is the Least Significant Bit. The switches   |
   |  have the following decimal values: SW1/1=32768,           |
   |  SW1/2=16384, SW1/3=8192, SW1/4=4096, SW1/5=2048,          |
   |  SW1/6=1024, SW1/7=512, SW1/8=256. Turn off the switches   |
   |  and add the values of the switches that are off to obtain |
   |  the correct memory address. (Off=1, On=0)                 |
