Zhongxin Chuangwei provides a time synchronization server to Beijing Tiantan Biological Products Co., Ltd.

Recently ， Beijing Tiantan Biological Products Co., Ltd. issued a requirement for a time server. Beijing Zhongxin Chuang Company responded proactively by preparing a detailed proposal for the customer and recommended its own independently developed and manufactured product. The DNTS‑8 time server, as the product being bid for in this round, underwent a fiercely competitive bidding process. Zhongxin Chuang, with its high‑quality products and comprehensive after‑sales service, emerged victorious over its competitors. The manufacturer’s products stand out. And Out, ultimately winning the time server project of Beijing Tiantan Biological Products Co., Ltd.

Beijing Tiantan Biological Products Co., Ltd. is an enterprise engaged in the research, production, and marketing of biological products, including vaccines, blood-derived preparations, and diagnostic reagents, and was established in… In 1998, by Beijing Institute of Biological Products (Its predecessor was The Central Preventive Medicine Bureau of the Beiyang Government, established in 1919, is the cradle of China’s biological products. It was listed on the Shanghai Stock Exchange, and its current controlling shareholder is… China National Biotech Group Co., Ltd. . With the company’s growth, it now boasts Changchun Qijian Biological Products Co., Ltd. , several households Plasma apheresis Companies, etc. Wholly-owned subsidiary 。

Beijing Tiantan Biological Products Co., Ltd. Developed independently by Zhongxin Chuang DNTS-8 Time Server Conduct an in-depth evaluation and arrive at the final results. All are superior to the parameter requirements. ， And Regarding our company’s product quality and after-sales service Also quite satisfied. ， Procured successfully and put into use. ！

Developed by Beijing Zhongxinchuang Technology Co., Ltd. The DNTS‑8 time server is a high‑tech, intelligent, stand‑alone clock synchronization server that operates on the NTP/SNTP protocols and delivers high‑precision time. It obtains standard time‑signal data from GPS satellites and disseminates this information across the network, enabling devices such as computers and controllers to synchronize with the reference clock. When all external signals are unavailable, the DNTS‑8 relies on its built‑in temperature‑compensated crystal oscillator for holdover, achieving a holdover accuracy of up to 1 × 10⁻⁹. The DNTS‑8 transmits standard time information over TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP; it also accommodates custom‑defined time‑broadcast packets with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. Additionally, the DNTS‑8 supports the broadcast mode of the SNTP protocol.
