Developed by Beijing Zhongxinchuang Technology Co., Ltd. DNTS-8 A time server is a high-tech, intelligent device that can operate independently and is based on… High-precision clock synchronization server compliant with the NTP/SNTP protocol. DNTS-8 The time server from Standard clock signal information is obtained from GPS satellites and transmitted over the network, enabling devices that require time synchronization—such as computers and controllers—to align with the standard clock. When all receivers are without a signal, DNTS-8 Using the built-in Temperature-Compensated Crystal Oscillator Punctuality, with timing accuracy reaching 1E-9。DNTS-8 Using standard clock information via TCP/IP network transmission, DNTS-8 Supports multiple popular time‑publishing protocols, such as NTP and time/UDP can also support New‑China‑Tech‑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. DNTS-8 Also supports The broadcast operating mode of the SNTP protocol
