|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) |
