Compact CAT5 Audio/Video Splitters and Receiver
6
CAUTION
Before plugging in the remote monitor, verify that the AC line is properly
wired and that a protective ground (green) wire is established with NO
potential difference between both the sender and receiver locations. The
splitter can tolerate up to 5 v peak-to-peak ground potential between the
two locations. Failure to ensure good grounding can result in erratic
operation and possible shock hazards or damage to your equipment.
NOTICE
Do not connect this unit to any LAN device such as network cards or hubs
as this may damage the UVA/URA and/or the LAN device. Use EIA/TIA
568B standard straight-through patch wiring as shown below. Do not use
crossover cables.
3. Configuration & Operation
3.1 Sender
At the sending end the video signal from the PC is fully terminated and buffered
for the local video output connector. This means that terminating or plugging a
local monitor is not necessary and this connector can be left open.
If a local monitor is plugged in, the plug-and-play ID information (DDC) of the
monitor is passed to the PC.
The stereo audio input is passed through to the local audio output connector and
the audio integrity is fully preserved. The transmitted audio in the CAT5 cable to
the remote receiver is monaural. The audio output on the standard receiver is
“line-level” (powered speakers are required). The Model URA-VOL provides
amplified audio output in addition to the line-level output for driving passive
speakers directly.
