LED and buzzer on VTAP PRO Cloud mode

LED and buzzer default behaviour

The following signals are used to indicate certain situations during start up and normal operation of a VTAP PRO reader in Cloud mode.

Note: Be aware that buzzer and LED functions can be modified from these defaults by your settings in VTAP Cloud online management platform, or by using a config.ini file to override the default behaviour described here.

Signal		Meaning
	Steady red	System is booting (typically <10 seconds). If the LED remains steady red for longer than 5 minutes there is an error - contact vtap‑support@dotorigin.com.
	Red flash every 1 sec	No network or Wi‑Fi. The VTAP100-PRO-BW reader will enter Hotspot Mode when it has been in this state for 3 mins.
	Blue flash every 1 sec	In Hotspot Mode [VTAP100-PRO-BW only], waiting for you to provide details for an available Wi‑Fi network. After 10 minutes the unit will automatically reboot.
	Red slow flash	Ethernet network or Wi‑Fi but no Internet (so not connected to VTAP Cloud). After 5 minutes the unit will automatically reboot.
	Steady blue (or default colour set in application)	Connected to the Dot Origin cloud, available for you to manage through the VTAP Cloud platform. Note: The steady blue LED will flicker every 30s in response to a heartbeat signal, giving visual confirmation it is still in communication with the VTAP Cloud.
Any	LED and/or beep (as set in application)	Instant reaction to mobile pass/card when presented
Any	LED and/or beep (as set in application)	Application response to mobile pass/card data received and processed

Note: The steady blue LED will flicker every 30s in response to a heartbeat signal, giving visual confirmation it is still in communication with the VTAP Cloud. Always wait a few seconds to be sure whether the LED signal is flashing or steady.
