       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)
