INTRODUCTION
With only one cost effective CAT.X cable, the AV-GM03W3-S1 lets you extend Composite signals up
to 330m (1,000ft). The devices are composed of a transmitter and a receiver. The transmitter is
installed near the signal source, and the receiver AV-GM03W3-S1-RX is placed near the desired
display. With built-in EQ and GAIN control, the transmission path can be adjusted to adapt the cable
quality and video bandwidth. Furthermore, the Composite RGB delay control [de-skew] function
provides the compensation among R, G, B signals due to long transmission or through normal LAN
cable. Analog stereo audio signals can be sent along with high quality Composite signal over long
distance LAN cable.
FEATURES
●Supports up to 720P@60Hz, 1080i@60Hz, 1080P@30Hz to 330m (1,000ft)
●Supports analog stereo audio and S/PDIF digital audio
●Adjustable equalization and gain control on RX unit
●De-skew compensation available for RGB delay control
●Wall mounting case for secure installation
PACKAGE CONTENTS

HARDWARE INSTALLATION
1. Connect your YPbPr and audio source to the transmitting unit.
2. Connect your display and speakers to the receiving unit.
3. Connect your CAT-5/5e/6 cable between the transmitting and receiving units.
4. Make sure your CAT-5/5e/6 cable is tightly connected and not loose.
5. Plug in 5V DC power cord to the power jack of the receiving unit.
6. Plug in 5V DC power cord to the power jack of the transmitting unit.
7. If a blurred video is seen or even worse, not displayed at all, try to adjust the EQ and Gain
rotary controls to improve the cable skew. GAIN rotary controls are designed for gain control,
and EQ rotary controls are designed for equalizing the wave form of the receiving video signal.
It is suggested to begin with adjusting the rotary control of EQ to get the input video displayed
first, and then the GAIN according to the video you see on the screen.
Please follow the steps as below to adjust EQ and Gain.
a. Set the rotary control of Y、Pb(Cb)、Pr(Cr) to max
b. Set the rotary control of equalization to the middle position, and then adjust the EQ to left
or right direction until the image is clear
c. After the image is clear, please adjust the rotary control of Y、Pb(Cb)、Pr(Cr)
P.S. Please check the RJ-45 connector and Cat.X cable and make sure they are not loose if the
image can not be adjusted correctly
8. RGB delay control [De-skew] offers the flexible functionality to allow skew compensation
among VGA R, G, B signals due to long transmission or thru low quality cable. By adjusting the
rotary switch to choose R, G or B color channel at first, then use the push buttons to increase
or decrease the delay in the corresponding color channel. There are totally 31 steps, each step
with 2ns difference, for adjusting the delay between each color individually. Then the graphics
quality can be further assured.

NOTICE
1. All transmission distances are measured using Belden 1583A CAT-5e 125MHz LAN cable and
ASTRODESIGN Video Signal Generator VG-859C. The transmission distance is defined as the
distance between the video source and the VGA display.
2. The transmission length is largely affected by the type of LAN cables, the type of video sources,
and the type of display. The testing result shows solid LAN cables (usually in bulk cable 300m or
1000ft form) can transmit a lot longer signals than stranded LAN cables (usually in patch cord
form). Shielded STP cables are better suit than unshielded UTP cables. A solid UTP CAT5e cable
shows longer transmission length than stranded STP CAT6 cable. For long extension users, solid
cables are your only choice.
3. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you can
use shielded LAN cables to improve EMI problems, which is worsen in long transmission.
4. Because the quality of the LAN cables has the major effects in how long transmission distance
will be made and how good is the received display, the actual transmission length is subject to
your LAN cables. For resolution greater than 1080i or 1280x1024, a CAT-6 cable is
recommended.
5. The analog audio is sampled by 48kHz before transmission; on the remote RX unit with S/PDIF
audio input, the only supported sampling frequency is 48kHz.
