Description
The board TCR511PEX has been designed to receive
different IRIG-A/B and AFNOR codes. The decoded date
and time can be read via the PCI Express 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 TCR511PEX 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.
The module is designed as a x1-board (single lane)
in "low profile" format. It is equipped with a
standard height bracket with integrated D-Sub
connector making the serial interface, the input for
unmodulated IRIG codes, the pulses per second and the
pulse per minute available. For installation in a
"low profile" computer, an adequate bracket can be
mounted that is included in delivery. The D-Sub
connector is only available when using an additional
bracket in this case.
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.

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.
