Note:

A total of 128 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. Jumper CMP9 is the Most Significant Bit and jumper CMP3 is the Least Significant Bit. The jumpers have the following decimal values: CMP9=512, CMP8=256, CMP7=128, CMP6=64, CMP5=32, CMP4=16, CMPA3=8. Jumper CMP10 is always on. Turn off the jumpers and add the values of the jumpers and convert to hexadecimal to obtain the correct memory address. (Off=1, On=0)
