            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)

            vertically should be closed with a jumper so that all pins
            are closed.
