The Differential Status LED is a two-color LED which provides information on the
availability of differential corrections to the receiver. The LED shows the number
of corrections received for each type: SBAS, Beacon, or Serial. The LED blinks
with the following repetitive sequence;
• One red flash followed by the number of SBAS input corrections green
flashes.
• Two red flashes followed by the number of Beacon input corrections green
flashes.
• Three red flashes followed by the number of Serial input corrections green
flashes.
The DG16 supports the use of external LEDs with the same features as the on-
board LEDs.

Sensor LED

The DG16 Sensor has a three-color LED on the front of the unit which indicates
the status of the receiver. Upon power-up the status LED flashes red until a
position has been computed. After computing a position, the status LED flashes
yellow or green in between the red power status flash to indicate the status for
each visible satellite.You can count the number of yellow or green flashes
between the red flash to know the number of satellites visible in the sky. Table 1.3
indicates the color and status for the LED.
