Audio & Video Formats/Resolutions/Distance; Irtx (Ir Transmit) Ports - AMX Endeleo UDM-RX02 Operation/Reference Manual

Audio & Video Formats/Resolutions/Distance
The following table provides allowed distances for video cable runs of various classes and formats: l

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:

IRTX (IR Transmit) Ports

Two 3.5mm stereo IRTX connections issue IR commands from the UDM hub to the controlled device(s):
A maximum of two IR devices (such as DVD players or VCRs) can be connected to the UDM via the
IRTX ports on the rear panel (FIG. 8), and controlled via the WebConsole or remote control.

Cable Distance: Naturally, long distance 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. Excessive skew
can adversely affect video image quality, especially at long cable lengths and high signal
resolutions.
