Note: A total of 256 base memory address settings are available. The jumpers are a binary representation of the decimal memory addresses. JP2/A is the Most Significant Bit and jumper JP2/H is the Least Significant Bit. The jumpers have the following decimal values: JP2/H=4, JP2/G=8, JP2/F=16, JP2/E=32, JP2/D=64, JP2/C=128, JP2/B=256, JP2/A=512. Open the jumpers and add the values of the jumpers that are open to obtain the correct memory address. (Open=1, Closed=0) | ||||||||
