Note:

A total of 128 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. Jumper A9 is the Most Significant Bit and jumper A3 is the Least Significant Bit. The jumpers have the following decimal values: A9=512, A8=256, A7=128, A6=64, A5=32, A4=16, A3=8. Turn off the jumpers and add the values of the jumpers and convert to hexadecimal to obtain the correct memory address. (Off=0, On=1)
