Description

The TM2500B is the latest addition to our NTP/PTP GPS time server product line. The TM2500B, like our other GPS NTP servers, provides a Stratum 1 time source 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 TM2500B uses an active GPS antenna to maintain the current time as broadcast by United States’ GPS satellites worldwide. 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 additional processing that was added to the TM2000B to provide a greater accuracy for holdover time is also included on the TM2500B. A BNC connector on the back of the device provides either a 10Mz reference frequency output or a 1PPS signal. With the powerful feature set, the OCXO reference clock with improved holdover accuracy, and reference output options, you cannot beat the price and capabilities of this GPS NTP server device. It is a small gem that adds so much to your network capabilities.

Every TM2500B kit comes with a 12V international power supply and a GPS patch antenna, and a 10MHz reference signal test report.

    Rack Mountable 0.5 inch POE NTP Clock

    $169.99

    The TM160 WiFi clock is a low profile clock based on the same hardware and software as our other NTP digital clock displays. The bright red digits are 0.5 inches tall. It is installed in the same case as our TM1000A and TM2000A time servers, making it an ideal solution for a rack mount companion to those products. It can be mounted using the same 1U rack mount face plates that the TM1000A/2000A use. Mount a single clock using the 760-022-000 plate, or mount a time server and a clock in a 1U space using the 760-023-000 dual rack mount plate. Its small size also makes it ideal as an interface to a campus wide bell system. It has the same relay output that our other displays have and all of the same versatility for alarm event setting through its web interface or using TM-Manager. The rack mount plate and relay connector is sold separately.
