Onair GPS Master Clock - Slave Led Display System
The system has a master clock that can manage a maximum 250 slave displays.
Master clock and slave displays are communicating through a local network, which can be Ethernet or WiFi.
Master Clock synchronizes clock using internal GPS receiver, stores clock information and with the built-in NTP (Network Time Protocol) server, all computers supporting NTP (Microsoft Windows, macOS, and most Linux operating systems support NTP) in your network can synchronize the clock.
Master Clock can display different information on Slave Displays, which can be controlled using the Remote Control System.
Slave displays can be any type of P10 (1R) HUB12 and HUB75 displays. Single color or RGB color. You have a huge range of possibilities to make the slave clock as you like.
Slave Displays control card can control a maximum of 15 pcs P10 HUB75 RGB displays.
Slave Displays can operate without a master, it can be remotely controlled, and can connect to any other NTP servers to synchronize the clock.
Master clock and slave displays are equipped with Real-Time Clock, so the system is not affected by the power outages.
