Description
The board TCR511PCI has been designed to receive
different IRIG-A/B and AFNOR codes. The decoded date
and time can be read via the PCI/PCI-X bus interface
and is also transmitted via the board's RS-232 port.
The receiver's automatic gain control (AGC) allows
the reception of modulated IRIG signals within an
amplitude range from 600mVpp to 8Vpp. In addition,
the TCR511PCI provides an optocoupler input for
decoding unmodulated codes with TTL- or RS485-level
for example. A buffered real time clock keeps time
and date after power down.
If you are going to use the TCR511PCI in your own
applications, please ask for our sample application
which shows how to access the card from within your
software.
All drivers and the API sample sourcecode 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.
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.
