Masterclock GMR1000 User Manual

The GMR1000 is a compact time and frequency generator/server that can reference
a variety of timing sources and provide a range of outputs to meet customer needs.
The base model includes both NTP client and server functionality compatible within
IPv4/IPv6 networks and oering Secure-Socket-Host (SSH) encrpyption for secure
communications. Properly congured and using standard NTP polling rates, the device
can support and synchronize hundreds of thousands of NTP clients.
