Note:A total of 63 node address settings are available. The switches are a binary representation of the decimal node addresses, and have the following decimal values: 1=1, 2=2, 3=4, 4=8, 5=16, 6=32. Switches in the off position maintain a zero value. Sum total the switches in the on position to obtain the correct node address. Node 0 is a non-valid address. | ||||||
