Description
RGB Technology ZBS 10-L PoE Indoor LED Clock supports 4 inch high Red LED digits displaying Hours, Minutes & Seconds. The Clock supports Automatic brightness Control and can be managed via a web browser or IR Remote Control.
Features
- 4 inch / 10 cm height LED digits
- NTP Ethernet Time Synchronisation
- Web Browser or IR Remote Control
- Supports Daylight Savings Time
- Automatic Brightness Control
The clock supports the activation of the automatic time change from the standard time to the daylight saving time and from the daylight saving time to the standard time (DST – Daylight Saving Time).
Automatic brightness control based on the measurement of ambient light by the sensor ensures real adjustment of the display brightness to the current lightning conditions of the surroundings. In addition to the automatic brightness control based on the sensor, there is a possibility to manually select
and lock one of 10 brightness levels.
NTP synchronization advantages:
– provides precise time synchronization with the NTP servers
– possibility of simultaneous synchronization of many clocks from the same server
– operation of five different time servers (1 primary and 4 alternative) provides reliable
synchronization.
– changing the time server from the primary to an alternative one is carried out automatically when
a failure is detected.
The NTP time synchronization is carried out via the Ethernet (the interface is included in the
standard equipment of every clock).
Function of the local NTP time server
Every clock of ZAS/ZBS series may be a central clock (MASTER) which, in the LAN, will provide the time source for other clocks (Slave). In consequence, it is easy to create a clock system in which the central clock can receive time from: a public NTP server or its own internal clock.
Providing synchronized time to all clocks guarantees that everybody uses the same time source. It is extremely important for workplaces, production halls, schools, stations, platforms, etc.
