9. Check LEDs on I/O board to verify power and
data are reaching dome (Figure 16).
a. Observe green (ac power) and yellow
(comm.) LEDs. Green LED glows steadily
and yellow LED glows steadily (RS-422,
Manchester) or blinks (SensorNet).
b. For RS-422, press and hold data test switch
SW1 and observe nearby red and green
LEDs; they indicate the following:
Constant green,
Blinking red
