GMR5000 Master Clock

The GMR5000 is a time server that can reference a variety of timing sources and provide a range of outputs including NTP, PTP, SMPTE, and IRIG-B. The internal modular design allows the unit to be factory-configured per the user’s requirements, giving flexibility while saving cost. The base model includes both NTP client and server functionality compatible with IPv4/IPv6 networks and offers SSH encryption for secure communications. Optionally, the device can act as a PTP IEEE1588 grandmaster or slave clock, time code generator, NENA time server, and more.
