Tag Description
SPL The SPL LED will light if the unit is not getting a response from one or
more of the configured devices.
For LonWorks units, LED will light until the unit is commissioned on the
LonWorks network.
RUN The RUN LED will start flashing 20 seconds after power indicating normal
operation.
ERR The SYS ERR LED will go on solid 15 seconds after power up. It will turn
off after 5 seconds. A steady red light will indicate there is a system error
on ProtoNode. If this occurs, immediately report the related “system error”
shown in the error screen of the GUI interface to Sierra Monitor Corpora-
tion for evaluation.
RX The RX LED will flash when a message is received on the serial port on the
6-pin connector.

pin connector.
If the serial port is not used, this LED is non-operational.
