The TM2000B is the next generation of our TM2000 GPS NTP appliances at the same great price. The TM2000B 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 TM2000B uses an active GPS antenna to maintain the current time as broadcasted by United States-based GPS satellites worldwide. In addition, a high stability OCXO reference clock is included that allows this GPS NTP appliance to serve time if GPS lock is lost for periods of time. Additional processing on the TM2000B provides a greater accuracy to this holdover time from our previous model. The unit is small and can be placed anywhere within the network layout.

2 Way GPS Splitter$69.95
The TimeMachines GPS 2 Way Splitter allows using one antenna with two GPS Time Servers such as the TM1000A or TM2000A. This passive device connects antenna amplifier power through one of the output ports to the antenna using the power provided by the time server. The second port is DC blocked. No changes in setup of the TimeMachines Time Servers are required to use this device. Compatible with other vendors GPS based time server products, see documentation for more information. Works great with the puck antennas provided with our time servers as well as our conical 40dB outdoor antenna. If there are multiple time servers co-located, this product can save running multiple antenna cables.

Rack Mountable 0.5 inch POE NTP Clock$169.99
The TM160 POE 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.
