UDM-0102 Wiring and Connections
10 UDM-0102 and UDM-RX02 Operation/Reference Guide
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:

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.
IRTX 1 & 2 (IR Transmit) Ports
Two IR-controlled devices (such as DVD players or VCRs) can be connected to the UDM-0102 via the 3.5mm
stereo IRTX ports on the rear panel (see FIG. 7 on page 8). This allows device control via the WebConsole or
remote control.
Use two IR01 IR Emitter Modules (FG-IR01 - not included) to connect the IRTX 1 & 2 ports on the
UDM-0102 to the IR receivers on the devices, to allow them to receive IR control signals directly from the
UDM-0102.

The device connected to IRTX1 represents Device "1" on the Devices page. IRTX1 transmits IR
commands to Device 1.

The device connected to IRTX2 represents Device "2" on the Devices page. IRTX2 transmits IR
commands to Device 2.

IR commands for each device on the system have to be learned by the UDM-0102 in
order to function properly. Refer to the Creating and Learning an IR Protocol
section
on page 59 on how to learn a device’s IR commands.
IR devices controlled via the IRTX ports are typically installed within the same
equipment rack as the UDM-0102.
