Zhongxin Chuangwei provides clock synchronization equipment to Capital Medical University.

Recently, Capital Medical University issued a request for a clock synchronization system. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed solution and recommended its self‑developed and manufactured DNTS‑9 time server as the bid‑winning product. Following a highly competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for Capital Medical University’s clock synchronization system project.

Capital Medical University was founded in 1960. It is a higher education institution in Beijing and a jointly established university by the Beijing Municipal Government, the National Health Commission, and the Ministry of Education. The late Professor Wu Jieping, an academician of both the Chinese Academy of Sciences and the Chinese Academy of Engineering and Vice Chairman of the Standing Committee of the National People’s Congress, served as its first president. The current Party Secretary is Researcher Hu Wenliang, and the president is Professor Rao Yi, a leading Chinese molecular neurobiologist.

Capital Medical University conducted an in-depth evaluation of the DNTS‑9 clock server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the university expressed high satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑9 network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization across all devices on the network.

◆Device information can be displayed:

GNSS satellite status: number of satellites, acquisition process, and tracking or hold‑off status; position coordinates (longitude, latitude, altitude)

Antenna status: operating, shorted, or disconnected

Network Status: Displays the IP address, subnet mask, and gateway for each network interface.

Device Status: Whether time synchronization is functioning normally and whether access limits have been exceeded.
