  • Page 47: Heat Dissipation

    Heat Dissipation The aluminum base plate of the unit acts as a heat drain, conducting heat away from VersaSync's interior components. When considering a mounting location, it is crucial that: the operating temperature of the mounting surface does not exceed 71°C/149°F.

  • Page 48: Grounding

    Grounding The VersaSync's DC power is not isolated from the chassis; during operation, the negative DC of the power source becomes the ground of the VersaSync and its chassis. Typical AC "earth ground" measures are unnecessary because of this design.

    3.3.1.2 The "Local System" Reference The Local System reference is a "Self" reference, i.e. VersaSync uses itself as an input reference for Time, or as a 1PPS reference. The Local System is a unique input reference in that it can be used as either the Time reference, or the 1PPS ref- erence, but never both.

    1PPS reference: VersaSync will transition to the Local System Time, without going into Holdover. Use case "Local System 1PPS" The Local System reference can also be used for 1PPS: This allows VersaSync to operate using an external ToD for time, while generating 1PPS from its own internal oscillator.

This history data can be used to determine if a GNSS reception problem exists and whether this is a continuous or intermittent reception issue.
  • Page 298 4.6  Quality Management Every hour (displayed in the log as UTC time), VersaSync counts the total num- ber of satellites that were tracked during that hour. The GNSS qualification log shows the number of satellites that were tracked followed by the number of seconds that the particular number of satellites were tracked during the hour (3600 seconds indicates a full hour).

    5.1.7 Troubleshooting – Network PCs Cannot Sync In order for clients on the network to be able to sync to VersaSync, several requirements must be met: 1. The PC(s) must be routable to VersaSync. Make sure you can access Ver- saSync Web UI from a PC that is not syncing.

    Windows synchronization. For UNIX/Linux computer syn- chronization, please visit http://www.ntp.org/. 3. If at least one PC can sync to VersaSync, the issue is likely not with Ver- saSync itself. The only VersaSync configurations that can prevent certain PCs from syncing to the time server are the NTP Access table and MD5 authentication.

    A terminal emulation program is used to emulate a video terminal, so as to access VersaSync's CLI (Command-Line Interface) remotely via a serial cable. This may be required if no other means of remotely accessing VersaSync are available, for example if Ethernet ports are used otherwise or have been dis- abled (e.g., for security reasons).

    5.4.1 About the IRIG Output Resolution The IRIG output signals are generated from VersaSync's System Time, which can be synced to one or more external input references (such as GPS, IRIG, PTP, etc). The accuracy of the System time to true UTC time is dependent upon what the selected external reference is (with GPS typically being the most accurate ref- erence for the system to sync with).
