   |   Note: A total of 255 base address settings are           |
   |   available. The switches are a binary representation of   |
   |   the decimal memory addresses. Switch A9 is the Most      |
   |   Significant Bit and switch A5 is the Least Significant   |
   |   Bit. The switches have the following decimal values:     |
   |   switch A9=512, A8=256, A7=128, A6=64, A5=32. Turn off    |
   |   the switches and add the values of the switches that are |
   |   off to obtain the correct memory address. (Off=1, On=0)  |
