Product Overview:
The TQ5509 is a comprehensive time synchronization device developed by Changsha Tianqiong Electronics Technology Co., Ltd. for systems such as medical, educational, and government networks. With the continuous advancement of technology, enterprise information systems are becoming increasingly sophisticated and convenient, requiring more network devices and servers. For unified management, these devices and servers need to have consistent time. However, each device has its own clock, and without synchronization, the time difference between all devices and hosts in the network will increase over time. With the continuous development of various network applications, it is necessary to establish a time synchronization system in the enterprise network to calibrate the clocks of devices at all levels, achieving network-wide time synchronization and ensuring the normal operation of the entire network.
Device Features:
1. High-precision synchronization
Receives time from China Telecom base station wireless signals, eliminating the need for an outdoor antenna, making installation and placement easy.
2. Excellent network time synchronization performance
Supports time synchronization within the same LAN and across different network segments, providing time synchronization services for tens of thousands of clients; ports can be quickly expanded by connecting to a router;
3. High reliability and simple design
Uses a highly reliable ARM chip and a low-power design with no fan; the system uses a simple operating system, eliminating the risk of viruses or time tampering; includes fault alarm output;
4. Convenient installation and setup
Simple installation and debugging process: simply connect the antenna, turn on the power, connect to the router, and configure the devices that need to be synchronized. No third-party software installation is required. The chassis panel has no buttons; all settings are done via a web interface.
