Modifying Video Input Termination
Each video input (Video Source 1-4) is terminated with 75 Ohm. For proper video recep-
tion this termination is required. In some cases, termination is not desired, for example:
• The card is inserted into an existing video link via a T-piece.
• All four inputs are fed from one video source, for example, to provide 4 streams with
different resolutions from the same video stream.
• Several Videum cards are cascaded or run in parallel to other video equipment.
In these cases, the video termination requires a video amplifier or repeater. This can be
avoided by individually disabling the termination by removing the jumper. One termina-
tion must remain per video link and be as close as possible to the end of the whole link.
If the jumper is removed, the video termination is disabled. If the jumper is replaced, the
video termination is enabled (default).
