Field Installation: Introduction

SecureSync time and frequency synchronization system offers customizability and expandability via the addition of a range of modular option cards. Up to 6 option cards can be accommodated to offer not only synchronization to a variety of input references, but also numerous types of output signals, supporting an extensive number of traditional and contemporary timing protocols including:

  • digital and analog timing and frequency signals (1PPS, 1MHz/5MHz/10 MHz)
  • timecodes (IRIG, STANAG, ASCII)
  • high accuracy and precision network timing (NTP, PTP)
  • telecom timing (T1/E1), and more.

Note: The installation procedure varies, depending on the type of option card and the installation be installed.

Outline of the Installation Procedure

The general steps necessary for installing SecureSync option cards are as follows:

  1. If adding or removing option cards that provide a reference, optionally backup your SecureSync configuration (refer to [2]: Saving Refererence Priority Configuration, if applicable to your scenario or environment.)
  2. Safely power down the SecureSync unit and remove the top cover of the main chassis (housing).
  3. Caution: NEVER install an option card from the rear of the unit, ALWAYS from the top, after removing the chassis cover.

  4. Select one of the unused Slots as installation location for the new card. The chosen Slot determines the installation procedure (see [3]: Determining the Installation Procedure).
  5. Prepare slot (if required), and plug card into the slot.
  6. Connect any required cables and secure option card into place.
  7. Replace chassis cover, power on unit.
  8. Log in to the SecureSync web interface; verify the installed card is identified.
  9. Restore SecureSync configuration (if it had been backed up before, see above).


Before beginning any type of option card installation, please carefully read the safety statements and precautions under SAFETY: Before You Begin Installation.
