Page 6: Introduction
Introduction The transmission of coded timing signals began to take on widespread importance in the early 1950´s. Especially the US missile and space programs were the forces behind the development of these time codes, which were used for the correlation of data. -

Page 9: Features Tcr167Pci
Features TCR167PCI The board TCR167PCI was developed for computer systems with PCI-bus. It is designed as an universal board and can be used in systems with either 3.3 V or 5 V PCI slots therefore. The module supports clock speeds of 33 MHz and 66 MHz. TCR167PCI serves to decode and generate modulated (AM) and unmodulated (DC Level Shift) IRIG and AFNOR time codes. - Page 10 The microprocessor system of TCR167PCI is equiped with a Bootstrap-Loader and a Flash-EPROM. These features enable updating of the onboard software via the serial RS-232 interface COM0 by using the Meinberg program ‘MBG Flash’.

Page 12: Functional Description Of Receiver
Date and time kept in the realtime clock can be set by sending a Meinberg Standard Time Telegram to the serial interface COM0 or via the PCI bus. The internal system clock is always set to the received IRIG time, which might have a local offset to UTC. -
Page 13: Input Signals
The board TCR167PCI decodes the following formats: A133: 1000pps, amplitude modulated sine wave signal, 10 kHz carrier frequency BCD time of year, SBS time of day A132: 1000pps, amplitude modulated sine wave signal, 10 kHz carrier frequency BCD time of year A003: 1000pps, DC Level Shift pulse width coded, no carrier BCD time of year, SBS time of day... -

600 Ω or 5 kΩ) of the input for modulated codes (BNC) to comply with the requirements of several systems. Meinberg IRIG-generators have an output impedance of 50 Ω Ω Ω Ω Ω , to build a mat- ched transmission system when using a coaxial cable. If such a generator is used to synchronize TCR167PCI, the input impedance has to be set to 50 Ω... -
Page 15: Master Oscillator
Master oscillator As standard, TCR167PCI is equipped with a TCXO (Temperature Compensated Xtal Oscillator) optionally an OCXO LQ (Oven Controlled Xtal Oscillator) as master oscillator. The internal timing of the module, basis for the software clock, the pulses and the generated time code, is derived from this oscillator. If the reciver is synchro- nized by an incomming time code, the oscillator is adjusted to its nominal frequency. -
Page 16: Unmodulated Outputs
Asynchronous serial port TCR167PCI provides an asynchronous serial RS-232 interface called COM0. The serial port sends a time string in the format ‘Standard Meinberg’, ‘Uni Erlangen’, or ‘SAT’ either once per second, once per minute or on request with ASCII ‘?’ only. -
Page 17: Enabling Of Outputs
Enabling of outputs As standard, the generator, the pulse outputs, the serial interface and the optional frequency synthesizer are switched off after power up until the receiver is synchroni- zed. By using the monitor software TCR167PCI can be set up to enable the outputs immediately after reset without synchronization. -
Page 18: Connectors And Leds In The Bracket
This port can not be used as serial port for the computer. Instead, the clock uses the port to send out Meinberg's standard time string in order to control an external display or some other external device. The string is sent out once per second, once per minute or if requested by an incoming ASCII ‘?’. -
Page 19: Pin Assignments Of The D-Sub Connector
Pin assignments of the D-Sub connector Only the signals of the serial interface are connected to the D-Sub-plug directly. If another signal shall be connected to a pin of the plug, a DIP-switch must be set to the ‘ON’ position. Whenever an additional signal is connected to the rear panel, special care must be taken to the configuration of the cable used with the connector. -

Page 21: Frequency Synthesizer (Option)
Frequency synthesizer (option) The optional frequency synthesizer is capable to generate output frequencies of 1/8 Hz up to 10 MHz as sine wave signal and with TTL level into 50 Ω. If a frequency smaller than 1 kHz has been selected, the following decimal places lead to real fractions of Hertz: 0.1: 1/8 Hz... -
Page 22: Configuration Of Tcr167Pci
Configuration of TCR167PCI The selection of the IRIG code, configuration of the serial interface and a possible offset of the received IRIG time to UTC must be set up by the monitor software via the PCI bus. In contrast to AFNOR NFS 87-500 the IRIG telegram containes only the day of year (1...366) instead of a complete date. -
Page 23: Replacing The Lithium Battery
Replacing the Lithium Battery The life time of the lithium battery on the board is at least 10 years. If the need arises to replace the battery, the following should be noted: ATTENTION! Danger of explosion in case of inadequate replacement of the lithium battery. -
