The characteristic of consistent time

1Embedded industrial grade motherboard, embedded operating system.

2Provide multifunctional client network timing software.

3Physically isolated multi port output, supportingNTPagreement.

4No hard drive, shockproof design, stable and reliable system.

5．36通道GPSBeidou satellite reception, fast locking.

6. AdoptingGPS/BD2Dual system precision timing, supporting singleGPSSingle Beidou, Double BeidouGPSDouble BeidouGPS/Beidou joint timing has multiple timing methods, which can be modified through serial ports, panel menus, and other means.

7High punctuality accuracy. The internal timekeeping unit of the device adopts time-frequency measurement and control technology and intelligent taming algorithm. The crystal is selected as a high-precision constant temperature crystal oscillator, which makes the timekeeping accuracy of the device better than7*10^-9(0.42MS/minute)In the case of abnormal external time reference, the daily clock self time error shall not exceed0.6millisecond. If a rubidium atomic clock is selected,30The annual self travel time error will not exceed3millisecond.

Design principle of consistent time

1Principle of compatibility. The product is capable of timing various electronic devices and supports network devices such as routers, switches, and firewalls; supportwindows9X/NT/server2000/XP/server2003/vista/windows7/ /windows8/windows10/server2008/server2012TheLinuxTheUNIXTheIBM AIXTheSUN SOLARISTheHP-UXWaiting for the operating system; Support real-time electronic devices such as monitoring hosts and self-service banking machines.

2Principle of Scalability. This product can simultaneously time all terminal devices in the network, and the increase of terminal devices within a certain order of magnitude will not affect the normal operation of the system. This system can provide timing services across network segments without causing interoperability between isolated network segments.

3Principle of reliability. system support365*24Hourly startup ensures long-term, stable, accurate, and safe timely service.

4Principle of Convenience. This product is available onlineNTPThe protocol provides timing services without the need to install any software or hardware on terminal electronic devices or computers. The product is easy to install and the parameter configuration is simple. The timing request is initiated by the terminal electronic device, and the network bandwidth pressure is low.
