TimeMachine TM2000A

GPS NTP+PTP Network Time Server

The TimeMachines GPS NTP+PTP Network Time Server represents a major step forward in capabilities at a breakthrough price point. It will supply accurate time for all computers and time keeping devices on the network. Supporting both Precision Time Protocol (PTP) and Network Time Protocol (NTP), a Stratum 1 time source can now be available on the local network with no need for an internet connection. SNMP V2/V3 is supported on the device, authenticated NTP, Peer NTP lookup, and Manual time setting modes.

The TM2000A system uses an active GPS antenna to maintain the current time as broadcast by United States GPS satellites planet wide. In addition, a high stability OCXO reference clock is included that allows the unit to serve time if GPS lock is lost for periods of time. The unit is small and can be placed anywhere within the network layout. The built in high sensitivity GPS receiver is able to lock multiple satellites from within many buildings or from a window location, removing the requirement that outdoor antennas be installed in some applications. Outdoor antennas are available from TimeMachines including custom length cables and accessories.
