   |  Note: A total of 255 base address settings are available. |
   |  The jumpers are a binary representation of the decimal    |
   |  memory addresses. Switch SW1/1 is the Most Significant Bit|
   |  and switch SW1/8 is the Least Significant Bit. The        |
   |  switches have the following decimal values: switch        |
   |  SW1/1=512, SW1/2=256, SW1/3=128, SW1/4=64, SW1/5=32,      |
   |  SW1/6=16, SW1/7=8, SW1/8=4. Turn off the switches and add |
   |  the values of the switches that are off to obtain the     |
   |  correct memory address. (Off=1, On=0)                     |
