Overview
The NTP001 is a Stratum 1 NTP server that uses GNSS to keep UTC-traceable time and serve it to public or private networks without internet access. It can broadcast time over Ethernet or over RS232 and RS485 serial ports. Teltonika lists NTPv4 with authentication, Ethernet NTP accuracy of plus or minus 1 ms and more than 300 requests per second.
Built for
- Time sync for isolated networks
- Industrial control and SCADA timing
- Utility and substation networks
- Serial time distribution
