Note:Node address 0 is used for messaging between nodes and must not be used. A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch 1 is the Least Significant Bit and switch 8 is the Most Significant Bit. The switches have the following decimal values: switch 1=1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128. Turn off the switches and add the values of the off switches to obtain the correct node address. (On=0, Off=1) | ||||||||

Note:If the card is the last in the line of network cards, the onboard terminator may be enabled instead of using a T-connector and an external terminator. This setting is valid only with the AN-220. If using an AN-120, SW1/10 must be off. (Star topologies do not require the use of terminators) | ||
