IP-VFC Troubleshooting

The IP-VFC can be a fickle mistress. This page will go over various tips and tricks for overcoming common issues.

Slot Statuses

In the Feed View right clicking on the Slot there are various Statuses the cards can be in. Here is a list of those Statuses, what they mean and how to recover them:

• Failed Initialization
  • The card is using an old incompatible firmware.
  • To recover you will need to update the firmware.
  • When in this state the card will never output any signal until the correct firmward is installed and it can interact with Designer.
• VFC card not responding
  • There was connected at some point but is no longer responding to Designer. Likely software onboard the card has crashed.
  • To recover you will need to reboot the card by power cycling the server and re-seating the card.
  • A fully configured card will never enter this state on it’s own and will only ever end up in this state during configuration.
• Refresh rate is different
  • The card is set to output a different refresh rate than the GPU is configured for.
  • To recover you will need to press Apply Feed Settings.

Port Statuses

In the Feed View right clicking on the Port underneath the Slot there are various Port statuses. Here is a list of those Port statuses, what they mean and how to recover them:

• Stream Disabled
  • Designer was able to configure the card and output signal briefly, but the sync/genlock was unstable so the card has stopped outputting.
  • To recover you should check the upstream genlock signal.
  • A fully configured card will never enter this state on it’s own and will only ever end up in this state during configuration.
• Underrun
  • The card is not being fed video at the rate that it expects so it cannot output video frames at the correct framerate. You may see the signal stutter. This can be caused by an unstable upstream genlock signal
  • To recover you should press Apply Feed Settings again to make sure the GPU and IP-VFC cards are configured properly.
