   |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=32768, SW1/7=16384,         |
   |SW1/6=8192, SW1/5=4096, SW1/4=2048, SW1/3=1024, SW1/2=512,  |
   |SW1/1=256. Turn off the switches and add the values of the  |
   |switches to obtain the correct memory address. (Off=1, On=0)|
