What do the status LED's on the front panel of the LD2 show?

LED displays

Sync LED:  Illuminated when LD2 is locked onto the downlink beam.

ID LED: Illuminated when LD2 is enabled for service. Flashing when LD2 is disabled. Off when LD2 has never been enabled.

Message LED: Illuminated when a message has been received from the VERIPOS Helpdesk.

IF Lock LED: Present on older LD2’s. Illuminated when using a 70MHz antenna system and signal lock is detected in the internal upconverter. Not currently implemented. The IF lock LED is in the same location as that of the HF lock LED on the newer models of LD2.

HF Lock LED: Present on newer LD2’s. Illuminated when the internal HF/MF demodulator has signal lock.

GPS LED: Illuminated when the GNSS card is outputting a non differential GGA telegram through Port 1. Flashing indicates the number of satellites used in the position computation. Can be intentionally switched off in some configurations/applications.

DGPS LED: Illuminated when the GNSS card is outputting a differentially corrected GGA telegram through Port 1. Can be intentionally switched off in some configurations/applications.

Power LED: Illuminated when the internal DC power supply is activated.
