NTP network time server description

Product overview

SYN2136 The Beidou NTP network time server has a high precision timing GPS Beidou two generation satellite receiver, which supports three working modes such as single Beidou, single GPS and GPS Beidou mixture.The time server is equipped with a 1 NTP time service interface, which can be extended to 4 channels. Each path is an independent NTP time card, independent of each other and not interfering with each other. A piece of damage will not affect the normal operation of other modules.

thisTime serverIt has the functions of password authentication, firewall protection, SYN-flood defense, encrypted communication, heartbeat detection, redundant backup, remote maintenance and real-time monitoring. It also integrates WiFi wireless management function on the basis of wired management, so that users can directly manage the NTP network time server by mobile phone.

Key word SNTP time server, time server, network clock server.

Product function Time server

1)    GPS Beidou timing signal is used to establish time reference.

2)    Provide 1 route NTP network timing interface;

3)    The front panel shows the hours and seconds of the year, the number of satellites and the working state.

4)    Support windows, LINUX, UNIX, SUNSOLARIS, IBM AIX and other operating system time synchronization;

5)    Support NTP v1.v2.v3&v4 (RFC1119&1305), SNTP (RFC2030) and other agreements ;

6)    Support DHCP function, all access to LAN port network equipment, can automatically get to IP address;

7)    Excellent security performance, providing firewall protection, enabling SYN-flood defense, greatly improving the security of internal network and reducing risk.

8)    Support heartbeat detection function, multiple time servers or multiple network ports can be set to the same IP, redundant backup each other.

9)    Support WEB, SSH encryption communication and software monitoring settings of parameter management mode;

10)   Support WEB firmware upgrade, provide parameter backup and import, system local log and remote log sending function;

11)   Provide software and hardware watchdog design, QoS function (traffic monitoring) and network diagnosis.

12)   The parameter settings file can be exported and imported.

13)   Network configuration page supports internationalization (Multilingual) including Chinese, English, Japanese, Spanish, French, Italy, Russian, Ukraine and so on, and can set user name password and host name.

14)   Real time monitoring of load, run time, real-time traffic and memory status;

15)   Display real-time links, including IP, communication protocol and interactive data volume of client access time server, and display historical data in graphic form.

16)   You only need to input www.syn029.cn to log on to the NTP time server to avoid recording the trouble of IP.

17)   The built-in clock source can be selected as crystal source, constant temperature crystal oscillator, rubidium atomic clock and tame module.

18)   Serial port time, time, minutes, seconds, years, months and days per second.

19)   Output timing synchronization signal (1PPS), TTL interface output;

Product characteristics

A)    Reliable performance, compact size, high cost performance.

B)    Adopting the latest version of NTP/SNTP protocol is accurate and reliable.

C)    WEB Management page humanization design, generous and simple, wired and wireless WiFi landing at the same time;

A)    The overall power consumption is small, using no fan design, reliable and stable operation.

B)    Support SNMP network management function.

Typical application

1)    Computer network, computer application system and process control management system;

2)    The time unified system and all kinds of time display screens for power plant (station) and power grid center scheduling.

3)    Electronic commerce system, B2B online system and database preservation and maintenance system;

4)    Broadcasting, finance, mobile communications, petroleum, electricity, transportation, industry and national defense.
