Description
The 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.
In cooperation with Meinberg, the community
developed a driver for OpenBSD (www.openbsd.org) which
is called mbg.
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.
