The iDirect Modem LED Indicators
The iDirect modem has the following front panel lights: Power, Status, Transmit (Tx), Net, and Receive (Rx). The
explanations below are for Ground Control service with iDirect platform version 6.0.9.6 (standard continental US settings).
The Power light:
→ GREEN: AC Power has been applied to the unit.
The Status light:
→ GREEN: The option file is correct, the POST has completed successfully
→ Flashing: The POST is in progress
→ RED: The option file is not correct, or there is a serious fault in hardware / software.
The Transmit (Tx) light:
→ GREEN: The transmitter is enabled and active.
→ AMBER: The transmitter is not enabled. If this light has a slow flash, the transmitter is attempting to communicate
to the network, but has not yet locked. If this light does not come on, check your _Networking_ settings
and your _GPS_ settings.
The Net light:
→ GREEN: The modem has successfully locked into the network.
→ Flashing: The modem is in the process of acquiring the network, and will be online soon.
→ AMBER: The modem has “heard” the network, but has not yet been able to talk back.
→ Flashing: The modem has not yet “heard” the network, and is still waiting for it’s signal.
The Receive (Rx) light:
→ GREEN: The modem has successfully identified the satellite signal, and the Rx is locked.
→ Amber: The modem has not yet identified the satellite signal. This typically indicates either a severe radio-
frequency interference issue, a loss of signal due to line-of-sight disruptions, or that the antenna is not
correctly pointed.
The modem also has the following rear panel lights: LNB Pwr, BUC Pwr, Input Pwr, Ethernet Link / Activity light, and
Console Link / Activity light.
LNB Pwr Light:
→ OFF: The LNB (Receiver) is not receiving power from the modem. This normally indicates a serious
configuration issue.
→ GREEN: The LNB is receiving power from the modem. This should be the typical state.
→ RED: The LNB is shorting out, or there is damage to the coaxial cable to it.
BUC Pwr:
→ OFF: The BUC (Transmitter) is not receiving power from the modem. This normally indicates a serious
configuration issue, unless your system has a transmitter that is externally powered via a secondary
power source.
→ GREEN: The BUC is being powered by the modem. This should be the typical state.
→ RED: The BUC is shorting out, or there is damage to the coaxial cable to it.
INPUT Pwr:
→ OFF: The modem is not being supplied with power. Check to make sure that the power cord and transformer
connections are tight and correct.
→ GREEN: The modem is being powered. This should be the typical state.
