Status LEDs

VersaPNT's front panel status LEDs provide a real-time status overview: Eight (8) LEDs indicate the unit's current operating state:

The LEDs can be disabled, see Blackout Mode.

Blinking Intervals

The status LEDs can communicate five different operating states:

• "OFF"
• "ON"
• "FAST": blinking interval @ 8Hz
• "SLOW": blinking interval @ 2Hz
• "HEARTBEAT": sinus-shaped interval @ 1Hz

LED Lighting Patterns

The table below indicates LED status light patterns for common VersaPNT operating statuses.

Common light patterns

Start-up	HEARTB.	OFF	OFF	OFF	OFF	OFF	OFF	OFF
Acquiring fix	ON	FAST	FAST	FAST	FAST	FAST	HEARTB.	SLOW.
Software upgrade	FAST	OFF	OFF	FAST	OFF	FAST	HEARTB.	OFF

Legend, individual LEDs

Legend for Status LEDs

Icon	Light	Meaning
	OFF	No power
	HEARTBEAT	Booting
	ON	Powered
	OFF	No GNSS reception (0 satellites)
	HEARTBEAT	GNSS acquisition in process (≥ 1 satellite(s), or 1PPS OK, or Time OK
	SLOW	Jamming detected
	FAST	Antenna short circuit
	ON	GNSS is available as reference (1PPS and Time OK)
	OFF	Inputs not detected/all inputs are disabled
	FAST	1 or more input is missing, or invalid timing on 1 or more input detected
	ON	Inputs are enabled
	OFF	Unit is in Holdover (valid)
	ON	System Clock OK (valid)
	FAST	Invalid Time (Holdover period exceeded, or oscillator damaged)
	OFF	No output signal(s) detected/all outputs are disabled
	FAST	Malfunction detected (short circuit, or overload)
	ON	Outputs are enabled
	OFF	No network detected
	FAST	Network malfunction detected (e.g., no auto-negotiation)
	ON	Network OK, configuration OK
	OFF	Unit OK
	FAST	Unit requires attention; check other status LEDs, see Web UI
	HEARTBEAT	See table LED Lighting Patterns
	OFF	No position and navigation solution
	SLOW	Solution is in the Initializing state or the Aligning state
	ON	System is Aligned and represents the best solution

Note: Older hardware models may have a temperature symbol instead of the Position and Navigation symbol in the far right LED position. If you have a software version installed that is later than 1.4.0.a, this LED symbol will reflect the Position and Navigation status. The temperature alarms are now incorporated into the Fault LED status light.

LED Patterns during Boot Sequence

For the first five seconds after power-up all LEDs will be OFF. Then the Power LED will be blinking before it will be lit permanently. If you have configured your unit to operate in Blackout Mode, this will take effect once the blinking cycle ends.

Blackout Mode

All LEDs can be turned off via the Web UI.

The LED brightness level can be set from 63 (as bright as possible) to 0 (not visable).

To disable all LED activity via the WebUI:

• Navigate to MANAGEMENT > OTHER: LED Configuration, and set the Brightness level to "0".
