GPS synchronous clock system is widely used in power, radio and television, finance, transportation, industry, and national defense because of its high timing accuracy and stable performance.

The NTP protocol commonly used in GPS synchronous clock system is also called the network time protocol. It defines the corresponding message format and message type, and synchronize the computer time to a certain standard time through the Internet. The standard time is coordinated universal time (UTC).

NTP takes the time information transmitted by GPS time code as the reference standard, adopts the Client/Server structure, has high flexibility, and can adapt to all kinds of Internet environments. NTP can adjust the time automatically while correcting the current time, and it can be automatically adjusted. Even if the network fails, it can maintain the stability of time. NTP generates very little network overhead and has corresponding measures to ensure network security.The adoption of these measures enables NTP to acquire reliable and precise time synchronization on the Internet and make NTP a recognized time synchronization tool on the Internet.

In general, NTP provides about ten milliseconds in wide area network and sub millisecond or higher on LAN. In dedicated time servers, the accuracy is actually higher.

In terms of timing, the GPS synchronous clock system can be divided into NTP network time server, serial port time server, B code and PTP.

Commonly used computers, servers, medical devices, cameras and other network devices are supporting the NTP protocol, and are generally applicable to NTP network time servers. NTP timing mode recommends models of SYN2101 timing, SYN2136 type, SYN2151 type and SYN4505 type.

The GPS synchronous clock system uses the specific operation method first to connect the network port of the GPS time server to the HUB, and the network devices in the whole network can be set to realize time synchronization. Note that the commonly used operating systems have their own network time service, supporting NTP protocol, simply setting up the NTP service function. Time server factory default IP 192.168.0.132

If IP Ping fails during the operation and the problem of managing web pages can not be landed, try the following actions:

(1) find a firewall in the control panel and turn it off.

(2) close the network card which is not related to this test, and only retain one local connection.

(3) for equipment directly connected to PC, you must set up a static IP address with different IP for the PC computer.

Open the browser on the computer, enter the IP of the device in the address bar, and click enter to enter. Enter the account number and password, click on login, you can enter the management interface to carry out IP modification settings or other management operations.
