UDM-0404 Endeleo Multi-Format Distribution Hub
A/V Source Input Connectors
There are four sets of input connectors to the rear panel of the UDM-0404, labelled A, B, C and D
(FIG. 9).
Audio & Video Formats/Resolutions/Distance
The following table provides recommended maximum distances for cable runs, based on video class
type at various resolutions:
It is important to note that the maximum distances indicated above are not absolute, but are
recommended distances that have been tested to deliver video at the specified resolutions, without
significant signal degradation. In particular, lower resolutions (640 x 480, 720 x 480 and 800 x 600) can
often be delivered significantly further than what is indicated in the table.
Several factors affect the overall quality of the displayed video, including the quality of the twisted pair
cable and connectors used, the nature of the video image itself, as well as the particulars of the
installation and how the video is displayed and viewed.
Two major factors affect the quality of signal transmission include:
Cable Distance: Naturally, long distances cable runs (in excess of 300 meters/1000 feet) are
always subject to resistance and capacitance losses which can negatively impact the quality of
the image.
Skew: "Skew" represents the slight delay that results from the variation in wiring lengths for
each of the twisted pairs. The effects of skew on A/V signals increases with cable length.
