LED Function
Gateway/
Power Indicates that there is DC power applied to the unit.
Radio/
Power Indicates that there is current being drawn by the radio connected to the WAN/Radio
connector.
Gateway/
Link “OFF”: There are no serial links between this and other gateways specified or enabled.
“RED”: One or more of the serial links that have been enabled is not established.
“AMBER”: All enabled links are established, but an error has been detected in any of
the links.
“GREEN”: All enabled links are established; no errors have been detected.
“Steady Blink ON/OFF”: A serial link to another gateway has just been established
and the gateways are measuring and adapting to the jitter in the network.
“Momentary Blink”: Every time that an error is detected the LED will go momentarily
OFF
Radio/
Link If the wide area network connecting the two gateways consists of a radio link using the
AFAR radios, this LED indicates the state of the associated radio as follows:
”OFF”: The gateway has no communications with the local radio
“2 second off/ blink ON”: the associated radio is in auto SYNC mode and waiting for
a transmission from a peer radio or for an sync message (heartbeat) from the gateway.
“Half second blink ON/OFF”: The associated radio has a heartbeat and is transmitting.
However it has not yet received a reply from a peer radio.
“Steady ON”: The radio has found a peer and an RF link is established between the
two radios.
