Description
The USB5131 shows the reception quality via its
status LED and uses a buffered real time clock to
maintain the time while powered off. There is no
power supply required, it is powered by the Universal
Serial Bus.
The USB5131 provides a professional solution to
your time synchronization requirements in mobile
applications like field data acquisition with a
laptop/notebook and can be deployed whenever you need
to synchronize a standalone PC, laptop or server when
no PCI or serial port is available.
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.
The Meinberg Single-Driver-Concept simplifies
driver installation dramatically - there is only one
driver who supports all Meinberg PCI and USB devices
and if you use our free API to access your Meinberg
timing device from within your own applications, you
can use the same source code for both PCI and USB
devices.
