The Gefen 1:2 VGA Audio over CAT5
The 1:2 VGAAudio over CAT5 extends and duplicates your audio and VGA video
signals at distances of up to 1000 feet away. Remote A/V signals are received
from the 1:2 VGAAudio over CAT5 Sender via industry-standard CAT5 network
cables.
The 1:2 VGAAudio over CAT5 will extend analog VGA as well as analog Audio
and provide two full sets of A/V signal output on the receiving end.
How It Works
The 1:2 VGAAudio CAT5 Distribution Amplifier Sender unit is placed at the
source location. A standard CAT5 cable is run from the 1:2 VGAAudio over CAT5
Sender up to 1000 feet to the 1:2 VGAAudio over CAT5 Receiver unit. The 1:2
VGAAudio over CAT5 Receiver unit connects to your remote video displays and
audio inputs. A microphone jack provides bi-directional audio support.

How to Connect the 1:2 VGA Audio over CAT5
1. Connect the VGA video source to the VGAAudio Over CAT5 sending unit
using the supplied VGA cable.
2. Connect the audio source to the VGAAudio Over CAT5 sender unit using
the user supplied 3.5mm mini-phono jack stereo cable.
3. Optionally, connect the 3.5mm mini-phono jack stereo output from the
sender to a compatible device using a user supplied 3.5mm mini-phono jack
stereo cable.
Example: Use a microphone at the receiver’s location in this example
scenario. Connect a microphone to the 3.5mm mini-phono jack input on
the receiver. Then use a 3.5mm mini-phono jack stereo cable to connect
the sender’s output to a microphone input port on a computer or amplified
receiver.
4. Connect up to 2 VGA displays to the 1:2 VGAAudio over CAT5 receiving unit
using user supplied VGA cables.
NOTE: Both outputs are mirrored images of the VGA video source.
5. Connect up to 2 of the 3.5mm mini-phono jack audio outputs on the 1:2
VGAAudio over CAT5 receiving unit to amplified audio devices using user
supplied 3.5mm mini-phono jack stereo audio cables.
6. Optionally, connect a 3.5mm mini-phono jack stereo audio device to the
receiver for transmission back to the sender’s location. Please see the
example in step 3 for an example scenario.
7. Connect the 1:2 VGAAudio over CAT5 sending and receiving units together
using a single CAT-5, CAT-5e or CAT-6 cable (terminated according to the
TIA/EIA-568-B specification).
8. Connect the included 5V DC power adapters to both the sending and
receiving units.
9. Power on all displays first, and then the source.

ADJUSTING THE VIDEO QUALITY
Focus & Brightness
The 1:2 VGAAudio over CAT5 receiving unit can adjust both the brightness and
focus of the reproduced video signal. Differences in cable skew and distance are
factors that can affect these settings. To adjust these settings and tune the video
signal please use the steps below.
Brightness
If the image appears too dim or too bright, adjust the brightness Trim Pot on the
front of the 1:2 VGAAudio over CAT5 Receiver.
Insert a small flathead device into the brightness Trim Pot hole and turn the Trim Pot
in either a clockwise or counterclockwise direction. Turn the Trim Pot in very small
increments until the desired brightness is reached.
Focus
If the image is out of focus or if the image appears too sharp, adjust the focus Trim
Pot on the front of the 1:2 VGAAudio over CAT5 Receiver.
Insert a small flathead device into the focus Trim Pot hole and turn the Trim Pot in
either a clockwise or counterclockwise direction. Turn the Trim Pot in very small
increments until the image clears and there is not blurriness or smearing.
Color Shifting
The 1:2 VGAAudio over CAT5 receiving unit can also adjust each color
component (red, green, and blue) individually if color shifting appears on the
reproduced video signal. Differences in cable skew and distance are factors
that can affect these settings. To adjust these settings and tune the video signal
please use the steps below.
If an individual color, or multiple colors, appear to be shifted in the reproduced video
signal, please use the individual color Trim Pots on the 1:2 VGAAudio over CAT5
receiver to fix the convergence issues.
Insert a small flathead device into the desired color’s Trim Pot hole and turn the Trim
Pot in either a clockwise or counterclockwise direction. Turn the Trim Pot in very
small increments until the image clears and the convergence has been corrected.
Repeat this process for any of the three component colors.

Gefen has specifically engineered their products to work with the TIA/EIA-568-B
specification. Please adhere to the table below when field terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.
CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types.
Gefen recommends using solid core cabling. CAT-6 cable is also recommended
for best results.
Each cable run must be one continuous run from one end to the other. No splices
or use of punch down blocks.
