Status LEDs
VersaSync'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

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

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".
