should have a video supported format supported by your video monitor
or other destination connected to the routing switcher output.
 Confirm that any other switchers in the signal path have the proper input
and/or output selected.
 Use a Video Tester to test the video path leading to/from your Routing
Switcher.

 Verify that the video reference is terminated with a 75 ohm impedance.
Verify that the video reference is only terminated one time, and that the
termination is at the last piece of equipment in the video reference loop
thru chain.
 Confirm that the connecting cables are of high quality and not damaged.
Ensure you have selected the correct, supported SDI format for the
video reference you have connected to the routing switcher.
 Check that your video signal matches the SDI format you have selected
to provide “seamless” switching with the video reference format you
have connected to the routing switcher.
 Check that the video reference is the format you have selected for
“seamless” switching.
 Check that the SDI sources connected to the routing switcher inputs are
vertically locked to the video reference connected to the routing switcher.
