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.
