Description

GMR1000 Master Clock

 

The GMR1000 is a compact time server that can reference a variety of timing sources and provide a range of outputs including NTP, PTP, IRIG-B, and SMPTE. The base model includes both NTP client and server functionality compatible within IPv4 and IPv6 networks and offering SSH encryption for secure communications. Properly configured and using standard NTP polling rates, the device can support and synchronize hundreds of thousands of NTP clients. Optionally, the device can act as a PTP IEEE1588 grandmaster or slave clock, time code generator, NENA time server, and more.

FEATURES

 

  • Programmable relay closure 
  • 1 event/day with NO/NC dry contact relay 
  • IPv4/IPv6 compatible
  • SSH communication 
  • MD5 authentication
  • Internal TCXO maintains time during loss of external sync within ± 3 seconds/year
