GPS170PCI: GPS Clock for Computers (PCI/PCI-X Bus)
Product DescriptionThe GPS170PCI has been designed to synchronize the system time of computers with PCI/PCI-X bus interface and to provide an API (Application Programming Interface) which allows you to read the time with great accuracy and precision from within your own application.
The IRIG output of the GPS170PCI can be used to synchronize IRIG time code receivers. Using TCR167PCI slot cards provides a convenient solution to synchronize more than one standalone (non-networked) computer system - eliminating the need of deploying several GPS antennas.
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.
Additional drivers packages are available for DOS, Novell NetWare, and OS/2. At the bottom of this page there's a link to the download area.
The device's serial port can be used to update the card's firmware. Additionally it can be connected to the serial port of a computer to use the card as reference time source under operating systems where a serial time string is supported, e.g. by NTP, but no kernel device driver is available.
If you are going to use the GPS170PCI in your own applications, please use our software development kit which shows how to access the card from within your software.
All drivers and SDKs can be downloaded free of charges from our website and we are happy to assist you if you face any difficulties in using the Meinberg driver API in your software development process.
