VFC: Default Redundant Fiber Requirements

Potential Symptoms

  • VFC is flagging a controller error but can still communicate with display (error is informing user Redundant Fiber is not in use or available because only 1 of 2 fiber ports are in use.)
  • VFC System health reporting Connection to display error(Sync Loss) for only one:
    • Prolink A or Prolink B
  • DMP web user interface NTCIP error. Subsystem - Controller Status Error.
  • Controller error – ProLink A – Sync Loss or controller error – ProLink B – Sync Loss

Environment

  • VFC , DMP-50XX
  • Vanguard product

Cause

  • One of the two fiber ports is showing "Sync Loss"
    • This activates a controller error that will flag in NTCIP software
    • Redundant Fiber is required by default in the VFC configuration
  • With the correct VFC firmware the user is able to turn off the Redundant Fiber Requirement.
    • Sync Loss is still notated in the VFC but the error will no longer be notified in NTCIP software.

Resolution

  1. Login to the controller.
  2. Navigate to sign 1.
  3. Select Configuration.
  4. Select System
  5. Select Optional.
  6. Arrow down 3 times.
  7. Select Option 6 "Redundant Fiber Required."
  8. If you do not see the option available Firmware is most likely out of date
  9. Update VFC firmware to version v8.93.0.36 or newer. How to update firmware on a VFC controller 
  10. Select Redundant Fiber Not Required.
  11. Redundant Fiber requirements wont take effect until the VFC is Reboot.
  12. Cancel until back to Signs and Shared option
  13. Select Shared
  14. Select Option 4 Reset
  15. Select Option 1 Reboot and Confirm

For Temporary Operation

  • Previous steps provided could be considered as a temporary fix until redundant fiber is installed.
  • One fiber pair is the minimum requirement for communication
  • It is recommended to install redundant fiber when using Vanguard displays
    •  1 pair for port A (TX/RX) & 1 pair for port B (TX/RX). 
    • VFC Port A will feed to Port A of the first display and Port B on the VFC will connect to Port B of the last display. This creates the full Redundancy between the VFC and display(s).
