The network time server developed by Beijing Zhongxinchuang Technology Co., Ltd. DNTS-7 It is an intelligent, high-precision device. NTP network time server. DNTS- 7 Network Time Service Server from Standard time information is obtained from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and standard time services are provided over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can thereby synchronize with international standard time.
Use simultaneously Priority can be configured on GNSS satellite receivers, supporting single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations. Each receiver can be set to timing mode either independently or in conjunction with others.
DNTS-7 There is 1-4 one 10/100/1000M adaptive Ethernet ports, with physical isolation between ports to ensure data security; they can all be configured on the same network segment or on different segments, offering redundancy—failure of one port will not affect the normal operation of the others. Each Ethernet port must be assigned a unique IP address.
