Note: A total of 32 link address settings are available. The switches are a binary representation of the decimal link addresses. SW2/3 is the Most Significant Bit and switch SW2/7 is the Least Significant Bit. The switches have the following decimal values: SW2/7=2, SW2/6=4, SW2/5=8, SW2/4=16, SW2/3=32. Turn on the switches and add the values of the switches that are on to obtain the correct link address. (Off=0, On=1)

DIAGNOSTIC LED(S)
LED	Color	Status	Condition
LED	Unidentified	On	Self-test is in progress or self-test failed
LED	Unidentified	Off	Self-test passed
Note:The LED should go on when the board is first powered up. If the LED does not go off after a few moments, the self-test has failed.
