   |Note: A total of 128 base address settings are available.   |
   |The jumpers are a binary representation of the decimal      |
   |memory addresses. W9 is the Most Significant Bit and switch |
   |W3 is the Least Significant Bit. The switches have the      |
   |following decimal values:W9=512, W8=256, W7=128, W6=64,     |
   |W5=32, W4=16, W3=8. Turn off the switches and add the values|
   |of the switches to obtain the correct memory address.       |
