OVERVIEW

Network of computers are omnipresent. Synchronization of these computers is highly recommended at all enterprises. This integrates various diversified systems to work in unison.

The demand for improving the effectiveness of any system in place is met with time synchronization system deployed in the field. Troubleshooting is simplified by the application of time syncing equipment’s in the event of fault analysis.

Sertel NTP Time Server will act as a Stratum 1 server that generates precise time stamp signals to synchronizes various networks of devices, critical servers, electrical, communications devices such as SCADA, DCS, PLCs, LANs, Computer Buses, RTUs etc.
