The ideal solution for accurate time synchronization for your server or workstation PC when space is limited in your server rack - the GPS183PEX is a 12-channel satellite receiver based on Meinberg's GPS technology, implemented as a (low-profile) PCI Express card. This PC clock has been engineered from the ground up specially for time and frequency synchroniSation applications. The GPS183PEX is designed to receive signals from the U.S. Global Positioning System (GPS) and allows the PC's clock to be accurately synchronised and high-precision, high-accuracy time & frequency signals to be generated anywhere in the world.

The GPS183PEX features not only a BNC connector for amplitude-modulated timecode (TC AM) output, four status LEDs, but also a 9-pin D-Sub male connector with outputs for time signals generated by the GPS183PEX, including serial time strings and programmable signals (including pulse-per-second and pulse-per-minute signals).

The GPS183PEX is shipped with a standard slot bracket with recesses the antenna BNC connector, the AM timecode output BNC connector and the four status LEDs. This bracket also features an integrated D-Sub 9 male connector for outputting serial time strings and programmable signals.

The GPS183PEX also includes a 'low-profile' slot bracket which can be used to replace the standard bracket for installation of the GPS183PEX in low-profile chassis form factors such as 1U rack servers. When using the low-profile bracket, the signals that would otherwise be output via the D-Sub connector are instead output via a box header mounted on the board itself.

The drivers package for Windows contains a time adjustment service which runs in the background and adjusts the Windows system time continously and smoothly. A monitor program is also included which lets the user check the status of the device and the time adjustment service, and can be used to modify configurable parameters.

The driver package for Linux contains a kernel driver which allows the board to be used as a reference time source for the NTP daemon which is shipped with most Linux distributions. This also turns the computer into a NTP time server which can also provide accurate time to other NTP clients on the network. Some command line tools can be used to setup configurable parameters and monitor the status of the board.
