 |A total of 256 base address settings are available. The jumpers  |
 |are a binary representation of the decimal memory addresses. W9  |
 |is the Most Significant Bit and jumper W2 is the Least           |
 |Significant Bit. The jumpers have the following decimal values:  |
 |W9=2048, W8=1024, W7=512, W6=256, W5=128, W4=64, W3=32, W2=16.   |
 |Turn off the switches and add the values of the switches to      |
 |obtain the correct memory address. (Close=1, Open=0)             |
