LED States

The LED on the 3DM-CV7 uses both color and blink pattern to convey information about the operating state of the system. Users can get information on the GNSS system, RTK corrections,filter mode, data streaming mode and more through the LED interface.

To better understand the Navigation Filter modes described by the LED, see Filter States.

 

*Only the first 32-bits of the continuous BIT cause a red LED. The most common error conditions are buffer overruns due to streaming too much data for the selected baud rate.

LED Color	System State
Blue	Filter is in Full Navigation mode and processing differential corrections
Green	Filter is in Full Navigation mode
Yellow	Filter is not in Full Navigation mode (Initialization, Vertical Gyro, or AHRS mode)
Red	Continuous BIT error.* See Built-in Tests for full list of errors.
Solid White	System is initializing
Violet	Non-standard operating mode

 

LED Blink Pattern	System State
Slow Pulse	Idle
Fast Blink	Transmitting data or command responses
White Flash	Blinks in sync with the PPS when it's available
White/Blue Flash	PPS and receiving RTCM or SPARTN correction data
