To Set the Reference Format

The switcher gets the reference signal from the router and both the switcher and trigger 1 on the router must be set to the same format.

Note: Reference B (REF B) on Ultrix is not supported at this time.
  1. From the DashBoard tree view for the router, expand the Ultrix > Devices > Controllers + Matrices node.
  2. Double-click on the node for the router.
  3. Click (Frame Configuration) > References.


  4. In the Detect References table, the REF A shows the current reference signal that has been detected by the router.
  5. In the Triggers table click on the SDI Video Format for ID 1 and select the video format that the switcher will be operating in. Trigger 1 is the reference trigger used by the switcher.
  6. On the switcher control panel menu, press Press HOME > Setup > Installation > More > Reference


  7. Use the Ref Format knob to select the format of the reference that the router is set to.
  8. Use the Video Format knob to select the video format that the switcher will be operating in. This must be the same format that you set on the SDI Video Format for trigger 1 on the router.
    Note: If you are changing between HD and UHDTV1 video formats, the SDPE blades need to be rebooted. When the blades reboot you may need to reboot the Ultrix router to initialize the new configuration on the router.
