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

Note: A total of 255 base address settings are available. The switches are a binary representation of the decimal memory 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=131,072, SW1/7=65,536, SW1/6=32,768, SW1/5=16,384, SW1/4=8,192, SW1/3=4,096, SW1/2=2,048, SW1/1=1,024. Turn off the switches and add the values of the switches that are off to 912 to obtain the correct memory address. (Off=0, On=1) |
