10. 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 (RS422,
Manchester) or blinks (SensorNet).
b. For RS422, press and hold data test switch
SW1 and observe nearby red and green
LEDs; they indicate the following:
Constant green,
Blinking red
RS422 line correctly
wired.
Constant green,
No red
RS422 “Data In –”
shorted to ground.
Constant red,
Blinking green
“Data In +/ –” wires
reversed.
Blinking red,
Green off
“Data In +” shorted to
ground.
Both LEDs off “Data In +/ –” wires
shorted or open.
