----------------- Introduction
The “VGA CAT5 Extender” pair enables you to transmit VGA
signals up to 150M (500 ft.) away with resolution up to 1024 x 768.
Featuring common mode noise suppression circuit for superb VGA
quality via inexpensive unshielded twisted pair CAT5 cables. The
Local unit duplicates the input signal for local use and transmits the
VGA signal to a Remote unit. Upon receiving the VGA signal via a
CAT5 connector, the Remote unit broadcasts the signal to two VGA
outputs. A convenient Gain (equalization) control selector on the
Remote unit is designed for optimum signal clarity according to the
length of the CAT5 cable.
The “VGA + Audio CAT5 Extender” has all the functions of the
“VGA CAT5 Extender” with an added feature for audio signal.
Both pairs are ideal for public broadcasting, exhibits, retail stores,
courtrooms, stock tickers, bus station and many more applications.

----------------- CAT5 Cable
The Extender Pair requires a piece of UTP (Unshielded Twisted
Pair) CAT5 cables no longer than 150 meters (490 feet).
The cable must be wired according to the EIA/TIA 568B industry
standard as shown below.

The "VGA + Audio CAT5 Extender" accepts one stereo signal (the
left and the right channels) input on an audio jack (similar to a
computer). This stereo signal is broadcasted to the two local audio
outputs and is "mixed" together to form a mono signal before
transmitting to a Remote unit via CAT5 cable. Therefore, the left
channel and the right channel audio signals at a Remote unit are
the same.
After all connections are secured, you may plug in the power
adapters into the power jacks of the Local and the Remote CAT5
Extender units and plug the power adapters into AC outlets.

----------------- Operation
LED
There are two LEDs on the Local unit. The POWER LED must
illuminate indicating the unit is properly powered. The ACTIVE
LED illuminates when there is VGA input signals.
Likewise, the POWER LED of the Remote unit illuminates
indicating the unit is properly powered. Its ACTIVE LED illuminates
when VGA signals are properly decoded for the two local HDB15
VGA ports. The ACTIVE LED never turns on, if the "VGA + Audio
CAT5 Extender" is used to transmit audio signals only.
Equalizer selector
You may adjust the Equalizer selector on the Remote unit to get
optimum video signal for various cable lengths. There are four
segments of various lengths on the selector indicating different
length of cables. The following table can be used as a reference
for selecting the Equalizer.

----------------- Troubleshooting
Symptom Solution
No VGA signals at the Remote unit. . Both units must be powered
. ACTIVE LED on the Local unit and
the Remote unit must illuminate
indicating the signal is correct.
VGA signal is garbled Make sure the wires are correctly
wired inside the cable according to
EIA568A or EIA568B standard.
ACTIVE LED at the Remote unit is
always off.
. The ACTIVE LED of the Local unit
must be on. Check the wirings of
the CAT5 cable.
. Make sure the POWER LED of the
Remote unit is on.
VGA quality changes with the
change of CAT5 cables.
Use the Equalizer selector to adjust
the VGA signal for various cable
lengths and characteristics.
No audio signal at the Remote unit Make sure the volume is high
enough.
Audio signal at the Remote unit
becomes mono.
The Local unit mixes the left/right
audio signals before transmitting to
the Remote unit via CAT5 cable.
