Note:Node address 0 is reserved 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 most significant bit and switch 8 the least significant bit. The switches have the following decimal values: switch 1=128, switch 2=64, switch 3=32, switch 4=16, switch 5=8, switch 6=4, switch 7=2, switch 8=1. Turn Off the appropriate switches and add the values of the ‘off’ switches to obtain the correct node address.

DIAGNOSTICS LEDS
LED	Color	Status	Condition
LED1	Red	On	Accessing on board memory or I/O
LED1	Red	Blinking	System power up
LED1	Red	On	Transferring to and from the network
LED2	Green	On	Transmitting to another node
LED2	Green	Blinking	No node is accessable
LED2	Green	On	Coax Cable connected to a active network
Note:LED2 will blink at a rate based on the NODE address. If the NODE address is low, LED2 will blink at a slow rate. If the NODE address is above 128 then, LED2 will blink at a rate too high to be seen by the human eye.
