Zhongxin Chuangwei provides a precision clock to the Heilongjiang Provincial Museum.

Recently, the Heilongjiang Provincial Museum issued a request for a time server. Beijing Zhongxin Chuang Company promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑8 clock server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Heilongjiang Provincial Museum’s clock synchronization equipment project.

Heilongjiang Province Museum Located at Heilongjiang Province Harbin City Nangang District , founded in 1906, with the main building being a Europe Baroque architecture, originally Russia The former site of the shopping mall, is Country A Grade I protected building.

The Heilongjiang Provincial Museum conducted an in-depth evaluation of the DNTS‑8 clock server, independently developed by Zhongxin Chuang, and found that all test results exceeded the specified performance requirements. The museum also expressed high satisfaction with our product quality and after-sales service, resulting in a successful procurement and 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 time. The DNTS-8 obtains standard clock signal information from GPS satellites and transmits this data 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 holdover, achieving a holdover accuracy of up to 1E‑9. The DNTS-8 disseminates standard clock information via TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP; it also accommodates Zhongxinchuang’s proprietary time‑broadcast packets over 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 SNTP protocol’s broadcast mode. It features four adaptive 10/100M Ethernet ports, which are physically isolated from one another to ensure data security, allowing full configuration on the same subnet or on different subnets while providing redundancy; a failure in one port will not affect the normal operation of the others. Each Ethernet port must be assigned an independent IP address.
