    BNC, 2-pin plug and socket, or ST Fiber. Non-fiber outputs can be ordered as TTL, RS422/485, or high voltage switching. All TCG 01-G units feature a front panel display (Figure 1) giving visual feedback about the time data being generated on the outputs.

  • Page 6: Front Panel

    2. FRONT PANEL Figure 2 TCG 01-G front panel TCG 01-G features two LED indicators on the front panel (Figure 2), together with a 2-line by 16- character backlit LCD display. SYN LED: This LED shows the status of the current sync source.
  • Page 7 Values Description This character represents the total number of satellites currently present in the sky according to the GNSS position means that TCG 01-G has lost its knowledge of the Satellites in GNSS the sky been in storage for an extended period, or if the GNSS receiver has been reset.

  • Page 8: Contrast Adjustment Mode

    The SYN LED shows the status of the sync source. The various states are shown as follows:- State Description The TCG 01-G has no power The TCG 01-G is synchronized to the source indicated by the LCD display TEK-TCG 01-G-Manual-v5-092016 P a g e www.tekron.com...
  • Page 9 The ALM LED indicates the internal alarm status of the TCG01-G. It has only two operating states:- State Description The TCG 01-G is operating normally. i.e., there are no alarms Alarms are active. In this case, the actual alarm state is shown on the top Fast Flash (5 per second) line of the LCD display, replacing the normal date information (see example in Figure 3f above).

    PC serial port. A suitable 2 m cable is included with each TCG 01-G purchase. The CTS and DSR lines are permanently asserted. As the serial outputs are usually precisely timed messages, there is no provision for either hardware or software flow control.

  • Page 14: P5: Am Irig-B Output (Bnc Connector)

    P4-pin 1 is not available on TCG 01-G with DTE serial ports. If not specified, TCG 01-G will ship with a DCE serial port. P5: AM IRIG-B Output (BNC Connector) P5 provides AM IRIG-B (B12x) over a BNC connector. This output is not programmable for other types of signal and a 1 kHz carrier is present whenever the unit is powered.

    -energized state of the relay. The convention used in the TCG 01-G is to have the alarm relays energized during normal operation, and de-energized in the alarm state. In the case of all power to the clock being lost, all of the alarm relays act).

  • Page 16: Installation

    To reset the unit, the power must be cycled. To cycle the power, it is recommended that the external power source switch that the device the TCG 01-G is connected to; is turned OFF, wait a full ten seconds, and then turned ON again. This will result in the TCG 01-G having to resynchronize with the GNSS satellites.

  • Page 17: Event Recording Function

    TCG 01-G stores time tags in a data queue designed as a circular buffer. The maximum number of time tags that may be stored is 512.If further events occur when the buffer is full, TCG 01-G sets an overflow status and continues storing tags, overwriting the oldest data first.

  • Page 18: Tcg 01-G Commands Related To Event Time Tagging

    Note that the TCG 01-G native serial protocol does not include station addressing. In a network-connected system, the address of the Serial to Ethernet interface device can serve as the station address.

  • Page 19: Notes Concerning The Ps Command

    Notes concerning the Ps command: An ASCII [space] is transmitted if there is no alarm condition present The TCG 01-G can track up to 14 satellites simultaneously. The message limitation of 9 is to retain compatibility with older equipment using this message format.

  • Page 20: Pr Command: Repeat Last Tag Sent

    This feature provides a means to monitor /control signal activity on the two input channels of P6. The TCG 01-G clock supports both IRIG-B and event input functions on the two P6 input lines (Figure 10). If one IRIG-B input function and one Event input function are selected, then P6A should be connected to the Event input source, and P6B connected to the IRIG-B signal source.
