    Why does my Spectracom SecureSync show Stratum 15?
    • A
      Ann MontoyaAug 16, 2025
      If the Spectracom Controller displays 'Stratum 15', it means NTP is not synchronized to its available input references. This can happen if the SecureSync was in Holdover mode, but that mode expired without the return of valid inputs. To resolve this: 1. Verify that all available references are enabled in the Configure Reference Priorities table. 2. Verify that the Reference Status on the HOME page shows “OK” (Green) for all available references.

      Nicholas ShawAug 19, 2025
      If you cannot log in or access the Web UI of your Spectracom Controller and see the error message “Forbidden You don’t have permission to access/ on this server”, it means your PC is not listed as an allowed source. To restore access: 1. Log in from a PC that is listed as an Allow From in the access table, or 2. Perform an unrestrict command to remove all entries from the Network Access Rules table if the allowed PCs are unknown.

    Why is the LED on my Spectracom SecureSync red?
    • J
      Jennifer ClarkAug 22, 2025
      If the LED on your Spectracom Controller is red, it indicates a Time Sync alarm. This occurs when the SecureSync was just powered on and hasn't yet synced to its references, or if all available reference inputs have been lost and the Holdover mode has expired. To resolve this: 1. Ensure the Input Reference Priority table still has the desired inputs enabled, based on your desired priority. 2. Verify that the desired input references are still connected to the correct port of the SecureSync.

    What to do if Spectracom SecureSync input references are not valid?
    • M
      Michelle YoungAug 26, 2025
      If one or more input references on your Spectracom Controller indicate “Not Valid” (red), it means all available Input References have been lost. To fix this: 1. Make sure the Input Reference Priority table still has the desired inputs enabled, based on desired priority. 2. Make sure desired input references are still connected to the correct input port of SecureSync.

    Why is the LED on my Spectracom SecureSync orange?
    • A
      Anita WhiteAug 28, 2025
      If the LED on your Spectracom Controller is orange, it indicates that it is in Holdover mode because all available inputs have been lost. To resolve this: 1. Make sure the Input Reference Priority table still has the desired inputs enabled, based on desired priority. 2. Make sure desired input references are still connected to the correct port of SecureSync.

    What does blinking orange LED on Spectracom SecureSync mean?
    • D
      Dustin DyerAug 31, 2025
      If the LED on your Spectracom Controller is blinking orange, it means a GNSS Antenna problem alarm is asserted. To solve it: 1. Verify the GNSS antenna is connected to the SecureSync GNSS input connector. 2. Check the antenna cable for an open or short.

    How to fix Spectracom SecureSync Controller when source may not be applied?
    • G
      griffitheddieSep 3, 2025
      If the 1PPS and/or the 10 MHz output(s) are not present on your Spectracom Controller, it indicates that the source may not be applied. To resolve this: 1. Ensure the Input Reference Priority table still has the desired inputs enabled, based on desired priority. 2. Ensure desired input references are still connected to the correct input port of SecureSync.

    Why is the LED off on my Spectracom SecureSync?
    • P
      paulcamposSep 6, 2025
      If the LED on your Spectracom Controller is off, it means there are no valid Reference inputs available since power-up. To solve this: 1. Make sure the Input Reference Priority table has the desired inputs enabled, based on desired priority. 2. Make sure the desired input references are connected to the correct port of SecureSync.

    How to fix a blank LED on Spectracom Controller?
    • M
      Michael SchaeferSep 9, 2025
      If the LED on your Spectracom Controller is blank (not lit), it means SecureSync has no AC and/or DC input power applied. To fix this: 1. Verify AC power is connected to an AC source and the AC power switch is ON. 2. Verify DC power (within the correct voltage range, as stated on the DC connector) is applied to the DC power connector.

    How can I fix Spectracom Controller unable to track satellites?
    • M
      marcuschapmanSep 12, 2025
      To resolve the issue of being unable to track the minimum number of satellites on your Spectracom Controller, ensure that the GNSS antenna is installed outdoors with a clear view of the sky. Many factors can prevent the GNSS receiver from tracking the minimum number of satellites.
