Note: A total of 32 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. J6 is the Most Significant Bit and jumper J1 is the Least Significant Bit. The jumpers have the following decimal values: J6=512, J5=256, J4=128, J3=64, J2=32, J1=16. Open the jumpers and add the values of the jumpers that are open to obtain the correct memory address. (Open=1, Closed=0)
