Network Time Server

With the swift development of computer network, the network application is very common now, and network systems in multitudinous domains, such as the electric power, the petrofactionchenical, the finance industry (stock, bank) , the broadcast and television industry (broadcast, television) , the transportation industry (train, airplane) and so on need to maintain the computer’s time synchronization and time accuracy at wide range. Therefore, a good time generator is extremely essential. In order to adapt these domains’request of more and more precise time, Silimin Company has independently developed the SNTS network timing server on the basis of SGPS series product. Besides inherits all functions of the satellite synchronization clock, embeds the international popular NTP-SERVER service, provides the precise time proofreading service to each network equipment by the NTP agreement, and it is independent to other network systems that may directly access the network as the network timing server. In addition, it has many kinds of time correction ways and easy to operate.

Features

Large screen liquid crystal display; Chinese-characterizing menu operation; good human-machine interface; lightly key-touch control, convenient and nimble to use.

One or two routes network (RJ45) timing; provides the IP address which may set up as the independent network time server, provides the high accurate network time correction service by the international popular NTP-SERVER agreement, and also provides NetTime software which is suitable to WINDOWS, UNIX and other different operating systems, time unification proofreading request at different WebPages.

Uses American MOTOLORA Corporation’s specialized GPS timing chip, high time precision and strong signal capture ability. It has passed the international approved USNO laboratory’s widespread tested 6 Sigma outstanding timing level. If needed, may provide the complete set test report;

Uses the Motorola 32 high performances one-chip computer and commercial real-time multi- duties operating system, highly guarantee the stability and the operating speed of the product.

High quality industrial part, high level electrical design and high density integration electric circuit structure enable the equipment to have outstanding electrical isolation and electromagnetic screen performance, there is no adjustable component of the entire machine, enormously enhance to safeguard the device anti-interference and reliability.

Wide voltage area cross-direct current input, in order to satisfy user’s different request for power.

Has multi-route programmable setting for the second, minute, hour synchronous pulse out, and may through the serial port to output the time information, convenient for all kinds of automatic equipment to choose.

The equipment has multi-serial information output and interactive ways, as well as the IRIG-B sinusoidal modulation output and the IRIG-B direct current bias output ways, satisfies the user’s different signal utilization request;

All signal output of the equipment must through photoelectric isolation, ; strong anti-interference.

Strong reliability of signal receiving, unrestricted to power station regional condition.

Framework structure; 1U or 2u, 19” standard box, easy and convenient to install and use.
