            Note:The settings for JP3 and JP5 are identical to JP4. JP4
            sets the interrupt for port 1, JP5 sets the interrupt for
            port 2, and JP3 sets the common interrupt. For JP3, set
            identical jumpers to both JP4 and JP5.

            Note:The settings for JP2 are identical to JP1. JP1 sets the
            address for port 1 and JP2 sets the address for port 2.

            A total of 128 base address settings are available. The
            jumpers are a binary representation of the decimal memory
            addresses. JP1/A is the Most Significant Bit and jumper JP1/G
            is the Least Significant Bit. The jumpers have the following
            decimal values: JP1/A=512, JP1/B=256, JP1/C=128, JP1/D=64,
            JP1/E=32, JP1/F=16, JP1/G=8. Open the jumpers and add the
            values of the jumpers that are open to obtain the correct
            memory address. (Open=1, Closed=0)
