Time Server DNTS-8

The DNTS-8 offers 1 to 12 optional 10/100 Mbps auto‑negotiating Ethernet ports, with physical isolation between ports to ensure data security. All ports can be configured on the same network segment or on different segments, 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.

Product Overview

The DNTS-8 GPS/BD 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 GPS/BD time server acquires standard clock signal information from GPS or BeiDou geostationary satellites and transmits this information over the network, enabling devices in the network—such as computers and controllers—that require time signals to synchronize with the standard clock. When both GPS and BeiDou receivers are used, a priority can be defined; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver has a signal, the DNTS-8 GPS/BD relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timekeeping accuracy of up to 1E-9. The DNTS-8 GPS/BD transmits standard clock information via TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP, as well as custom time‑broadcast packets defined by Zhongxinchuang Technology, which can be configured to use specific 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 GPS/BD supports the broadcast mode of the SNTP protocol.

The DNTS-8 offers 1 to 12 optional 10/100 Mbps auto‑negotiating Ethernet ports, with physical isolation between ports to ensure data security. All ports can be configured on the same subnet or on different subnets, 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.
