            Note: A total of 254 node address settings are available. The
            switches are a binary representation of the decimal node
            addresses. SW1/8 is the Most Significant Bit and switch SW1/1
            is the Least Significant Bit. The switches have the following
            decimal values: SW1/8=128, SW1/7=64, SW1/6=32, SW1/5=16,
            SW1/4=8, SW1/3=4, SW1/2=2, SW1/1=1. Turn off the switches and
            add the values of the switches that are off to obtain the
            correct node ID. (Off=1, On=0)

            Node addresses 0 and 255 are reserved and should not be used.

            On some versions of this card, SW1 may be a one-use shunt
            instead of a switch.

            Note: A total of 128 memory address settings are available.
            The switches are a binary representation of the decimal
            memory addresses. SW2/1 is the Most Significant Bit and
            switch SW2/7 is the Least Significant Bit. The switches have
            the following decimal values: SW2/1=65,536, SW2/2=85=32,768,
            SW2/3=16,384, SW2/4=8,192, SW2/5=4,096, SW2/6=2,048,
            SW2/7=1,024. Turn off the switches and add the values of the
            switches that are off to obtain the correct address. (Off=1,
            On=0)

            On some versions of this card, SW2 may be a one-use shunt
            instead of a switch.

            you must cut the trace on W2/A andhard-wire a jumper with a
            soldering gun.
