Zhongxin Chuangwei provides clock synchronization equipment to Adisseo.

Recently ， Andisoo issued a request for a time server, and Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal for the customer. They recommended the DNTS‑8 time server—developed and manufactured in-house by Zhongxin Chuang—as the product to be submitted in the tender. Following a fiercely competitive bidding process, Zhongxin Chuang stood out by offering high‑quality products and comprehensive after‑sales service, ultimately securing the contract over competitors’ offerings. And out, Ultimately won the Andesu award. Time Synchronize server project.

Adisseo is a world-leading manufacturer of animal nutrition additives, with its flagship products holding a leading position in the global market. With a global network of subsidiaries and relying on its ten R&D centers and production facilities located across Europe, the United States, Singapore, and China, Adisseo designs, manufactures, and markets sustainable nutritional solutions for the animal feed industry.

Adisseo Developed independently by Zhongxin Chuang DNTS-8 The time server underwent rigorous testing, and the results consistently exceeded the specified performance parameters. We were highly satisfied with both the product quality and the after-sales service, leading to a smooth procurement and successful deployment.

The DNTS-8 time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high precision. The DNTS-8 time server obtains standard clock signal information from GPS geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. When all receivers lose signal, the DNTS-8 relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-8 disseminates standard clock information via TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP; it also accommodates custom‑defined time‑broadcast packets from Zhongxinchuang Technology, 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.
