The TimeMachines GPS NTP Network Time Server is a GPS-based NTP server device that supplies accurate time for all computers and time-keeping devices on your network. By placing a time server on the local network, (S)NTP time packets are provided without requiring systems to go to the Internet to get a Stratum 1 time synchronization. The TM1000A system uses an active GPS antenna to maintain the current time as broadcast by United States’ GPS satellites. With this device installed on your local network, there is no longer the worry that if the Internet connection goes down, time synchronization is lost across the network. The unit is compact and can be placed anywhere within the network layout, even using our new time server rack mounts. The built in high sensitivity GPS receiver is able to lock multiple satellites from within multiple buildings or from a window location, eliminating the requirement that an outdoor antenna be installed.
Setup and use of this time server is straightforward. Simply connect both the included power supply and the GPS antenna to the base unit and then connect the base unit to the local network. Go to a computer on the network and browse to the device at its default web address to enter the software setup within the control box. Set parameters to match your network and the system will start to send out time packets to any device on the system that asks for an update from it. When paired with our digital Power Over Ethernet (PoE) clocks, synchronized time is assured no matter the state of your network, or the state of the internet time server the clocks are pointed to. Accuracy is improved because the network delay of the internet is highly variable, while the local LAN connection is likely a sub-millisecond delay. TimeMachine GPS NTP server devices are suited for any application where coordination of events at multiple locations is required. Used by education, industrial facilities, military installations, public safety command rooms, government, broadcasting, and hospitals. Supports IPv4 and IPv6.

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.
