Page 9: Tcr180Pex Features
The board TCR180PEX has been designed as a "low profile" board for computers with PCI Express interface. Data transfer to the computer is done via a single PCI Express lane (x1 board). The TCR180PEX card decodes and generates modulated (AM) and unmodulated (DC Level Shift, DCLS) IRIG-A/B/G, AFNOR NF S87-500, IEEE C37.118, or IEEE 1344 time codes. -

Page 11: Master Oscillator
5 Master oscillator 5 Master oscillator By default the TCR180PEX is equipped with a TCXO (Temperature Compensated Xtal Oscillator) as master oscillator to provide a good time accuracy and frequency stability. As long as an input signal is supplied the frequency of the oscillator is adjusted from the input signal, and if the input signal is disconnected afterwards the card can still provide accurate time for a certain holdover interval. -
Page 12: Functional Description Of Receiver
So care must be taken that the on-board clock has been set to the correct date. The on-board date and time can be adjusted by sending a Meinberg Standard Time string to the serial interface COM0, or via the PCI bus by using the utility programs included in the driver software package. - Page 13 Most IRIG codes don’t include an announcement flag for the DST change, or for the for the insertion of a leap second, so the TCR180PEX will switch into free wheeling mode on such event, and resynchronize a few seconds later.
- Page 14 The board TCR180PEX decodes the following formats: Please note: all "A" und "G" Timecodes are only available after warmed up phase of the oscillator! A002: 1000pps, DC Level Shift pulse width coded, no carrier BCD time of year A132: 1000pps, amplitude modulated sine wave signal, 10 kHz carrier frequency...

Page 15: Input Signals
The time code format has to be configured using the monitor software: if an amplitude-modulated signal (IRIG- A/B/G, AFNOR NF S-87500, IEEE C37.118 oder IEEE 1344) is configured then the input signal has to be supplied to the upper BNC connector in the TCR180PEX’s bracket. A coaxial, shielded or twistet pair cable should be used. -

Page 18: Functionality Of The Generator
7 Functionality of the generator The time code generator of TCR180PEX is based on a DDS (Direct Digital Synthesis) frequency generator which derives the sine carrier of the modulated code from the reference clock of the master oscillator. The modulation of carrier amplitude (modulated codes) or pulse duration (unmodulated, DC level shift codes) is synchronized to the generated pulse-per-second (PPS) signalderived from the software clock. -
Page 19: Pulse Outputs
7.2 Pulse outputs The pulse generator of TCR180PEX provide three independent channels (PPO0, PPO1, PPO2). All of these TTL outputs can be mapped to pins at the 9-pin connector at the rear slot cover by using a DIP switch. Each output can be switched according to different, predefined conditions. -
Page 20: Asynchronous Serial Port
7.3 Asynchronous serial port Two asynchronous serial interfaces (RS-232) labelled COM0 and COM1 are provided by the TCR180PEX. Only COM0 is available at the rear panel slot cover, COM1 is accessible via the second ribbon cable connector on the card. The monitor program can be used to configure the outputs. In the default mode of operation, the serial outputs are disabled until the receiver has synchronized after power-up. -
Page 21: Enabling Of Outputs
7.6 DCF77 Emulation The time code receiver TCR180PEX generates TTL level time marks (active HIGH) which are compatible with the time marks broadcast by the German long wave transmitter DCF77. This long wave transmitter which is installed in Mainflingen near Frankfurt/Germany transmits the legal reference time of the Federal Republic of Germany: time of day, date of month and day of week in BCD coded second pulses. -
Page 22: Time Capture Inputs
7.7 Time capture inputs The TCR180PEX provides two time capture inputs called User Capture 0 and 1 (CAP0 and CAP1) which can be mapped to pins at the 9 pin connector in the rear panel. These inputs can be used to time stamp trigger slopes of asynchronous external hardware signals. -
