----------------- Introduction
Overview
The “Video+Audio CAT5 Extender” pair consists of one Local Unit
(Transmitter) and one Receiver Unit featuring to transmit Video+Audio
signals with the resolution up to WUXGA (1920 x 1200) / Full HD (1920 x 1080)
/ UXGA (1600 X 1200) via CAT5 cables. The Local Unit duplicates the
Video+Audio signals from one input source port to one or two local output
port(s) and transmits (duplicates) the Video+Audio signals to 1/4/8 Receivers /
Repeaters (Remote Unit) via the CAT5 connector; the Remote Unit
broadcasts the signal through two local output ports. A handy jog wheel on the
top panel allows users to manually adjust audio volume and video signal on
Gain (Brightness), Equalizer (Sharpness) and RGB skew in a way that is
simple and convenient. Better yet, the signal transmission distance can be
extended for another 200/300 meters by adding one more Repeater Unit in
between the Transmitter and Receiver, and up to two Repeater Units can be
added in between to achieve the maximum transmission distance up to 900
meters.
The “Video+Audio CAT5 Extender” pair is a dedicated design with the
characteristics of Flexibility in extending video signals at high resolution over
long distances, Convenience in manually and intuitively adjusting audio and
video signal via a built-in jog wheel, Security in allowing to locate computers in
the back room or secure location away from the display and protect it from
unauthorized use or public display, and Noise Reduction in removing the noisy
computer from the broadcast studio for the perfect and uninterrupted sound
reproduction. This makes it a great solution for public broadcasting, exhibits,
retail stores, courtrooms, stock tickers, and many more applications.

LED Selection
Transmitter Unit for 4-Port and 8-Port Models
There is a jog wheel on the top panel of 4/8-port Transmitter Unit, which can be
used to turn on/off the video signal output adjust the volume. A set of LEDs on the
top panel of the Unit is divided into two groups (as the figure shown below), namely,
“Group 1” that includes the video-audio pair LEDs on each of the local output
port and remote (CAT5) output ports 1, 2, 3, 4. (for both 4-Port and
8-Port models)
“Group 2” that includes the video-audio pair LEDs on each of the remote
(CAT5) output ports 5, 6, 7, 8. (available for 8-Port model only)
LEDs of Group 1 and
Group 2 on 8-Port
Transmitter
Group Selection (for 8-Port model only)
Step 1. Power on the Unit, the LED “Power/EDID Copy” will illuminate GREEN,
and the rest of the LEDs on the Unit will illuminate ORANGE.
Step 2. Connect the source computer to the input port on the Unit, the LED
“Power/EDID Copy” will turn to BLUE indicating that the signal input
is activated and the Unit is ready for configurations.
Step 3. Press and Hold the jog wheel for about 2 seconds, the LEDs on
both groups will flash ORANGE alternatively; then, users can
release the jog wheel to select the desired group.
Port Status Selection (Video/Audio)
Each output port associates with a pair of video and audio LEDs on the top
panel of the Unit. Within about 20 seconds after one group selected, users
can press the jog wheel once to switch the status port between video/audio.
14

For instance, the video LED on the remote output port 2 flashes ORANGE
indicating that the video signal of the output port 2 is selected. Before time
out (20 seconds), users can press the jog wheel once to switch the status
port from video to audio on the port 2.
Group 1 Output Signal Selection
As the figure shown below, the first LED (Monitor) flashes indicating that the
current output video signal is selected. Users can press the jog wheel once
at a time to switch port in sequence between video/audio among the output
ports of Group 1.
Monitor
Group 2 Output Signal Selection (for 8-Port model only)
As the figure shown below, the first LED (Monitor) flashes indicating that the
current output video signal is selected. Users can press the jog wheel once
at a time to switch port in sequence between video/audio among the output
ports of Group 2.
Monitor
NOTE: The Unit will automatically resume Stand By mode, if there is no jog
wheel activity detected within 20 seconds since the last activity
15

Receiver/Repeater Unit
There is a jog wheel on the top panel of Receiver Unit and Repeater Unit
respectively, which can be used to turn on/off the video signal output, adjust
the volume or adjust the video compensation. A set of LEDs on the top panel of
the Unit are divided into two groups, namely,
“Group A” that includes the video-audio pair LEDs on local output port(s) and
remote (CAT5) output port(s). (The remote output ports are available
for Repeater Unit only)
“Group B” that includes the LEDs of Skew (GBR), Gain (Brightness), and EQ
(Sharpness).
Group Selection
Step 1. Power on the Unit, the Skew LED will illuminate GREEN indicating that
the power is on and the Unit is ready for configurations.
Step 2. Press and Hold the jog wheel, the LEDs of group A and group B will
flash alternatively, and then release the jog wheel to select the desired
group. In general, users need to access to Group A for selecting an
output port (video or audio) first.
NOTE: The Unit will automatically resume Stand By mode (Group A and B
flashing alternatively), if there is no jog wheel activity detected within
20 seconds since the last activity
16

Group A Output Signal Selection:
As the figure shown below, the first LED (Monitor) flashes indicating that the
current output video signal is selected. Users can press the jog wheel once at a
time to switch one port selection in sequence among the LEDs of group A.

Switching cycle for port selection on Repeater Unit
Group B EQ/Gain/Skew Status Selection:
As the figure shown below, the first LED (EQ) flashes indicating that the
sharpness adjusting is activated, and users can press the jog wheel once at a
time to switch one status selection in sequence among the LEDs of group B.
Switching cycle for video adjustment on Receiver / Repeater Unit
NOTE: The Skew LEDs is a triple LED indicating three skew status such as
B(Blue), G(Green) and R(Red)
17

Output Signal (Video/Audio) Adjustment
Group (1,2,A) Output Signal Adjustment:
When one of the output statuses (video/audio) among these groups is
selected, the selected LED will flash indicating the activation; users can turn
the jog wheel by following the clockwise / counterclockwise direction to turn
on/off the video signal or to increase / decrease the volume as the diagram
shown below
The selected audio LED will emit ORANGE light according to the volume
strength. When users turn the jog wheel clockwise, the volume increased
and the ORANGE light strengthened, and vice versa. The diagram below
provides a comparison between the LED light strength and volume of OFF ~
7 levels.
NOTE:The CAT5 audio output signal on the Repeater Unit is not tunable
NOTE: Exit the mode through either one of the operation below.
Leave the Unit idle (no activity) for 20 seconds.
Press and Hold the jog wheel for two seconds.
18

Video Compensation
(Receiver / Repeater Unit only)
Group B EQ / Gain / Skew Adjustment on Receiver / Repeater Unit:
To optimize the video signal associated with various cable lengths, users may
adjust the video compensation via the jog wheel on the Receiver / Repeater
Unit.
Users can adjust the selected signal status (Equalization / Gain / BGR Skew) by
turning the jog wheel clockwise / counterclockwise. For example, tune the jog
wheel in counterclockwise direction as the diagram shown below to decline the
selected signal status, and vice versa.
NOTE: Exit the mode through either one of the operation below.
Leave the Unit idle (no activity) for 20 seconds.
Press and Hold the jog wheel for two seconds.
