INTRODUCTION
With only one cost effective Cat-5/5e/6 cable, the AV-GM03S3-S1 lets you extend VGA (WUXGA –
1920x1200@60) or 720p component video, bi-directional IR signals and RS-232 serial commands at
the same time to cover the distance up to 300m (1,000ft). The AV-GM03S3-S1 comes in a set of a
transmitter and a receiver. The transmitter AV-GM03S3-S1[Tx] is installed near the signal source
and has, and the receiver AV-GM03S3-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. In order to extend the control path, AV-GM03S3-S1 also built RS-232 half-duplex long
range extender along with VGA/component video signals.

You can buy any IR extension cables in the market that are compatible to the definition of
the IR sockets for the matrix if necessary for replacement use. However, IR cables longer
than 2m (6-ft) may not work.

HARDWARE INSTALLATION
1. Connect your VGA source, audio source, infrared and RS-232 devices to the transmitting unit
AV-GM03S3-S1[Tx]. If you want to connect to a component video source, please find a
VGA-component breakout cable and link it between the video source and the transmitting unit
of AV-GM03S3-S1.
2. Connect your VGA display, audio speaker, infrared and RS-232 devices to the receiving unit
AV-GM03S3-S1[Rx]. If you want to connect to a component video display, please find a
VGA-component breakout cable and link it between the video display and the receiving unit of
AV-GM03S3-S1.
3. Connect a Cat-5/5e/6 cable between the transmitting and receiving units.
4. Make sure this Cat-5/5e/6 cable is tightly connected and not loose.
5. Plug in 5V DC power supply unit to the power jack of the receiving unit AV-GM03S3-S1[Rx].
6. Plug in 5V DC power supply unit to the power jack of the transmitting unit AV-GM03S3-S1[Tx].
7. If you see the monitor is displaying blurred video or even worse, not displaying at all, please
adjust the EQ and Gain rotary controls to improve the cable skew. GAIN rotary control is to
adjust the gain to an appropriate level for a range of input signal levels (brightness), and EQ
rotary control is to equalize the wave form of the receiving video signal (sharpness). It is
suggested to begin with adjusting the rotary control of EQ to get the input video displayed first,
and then the rotary control of GAIN according to the video you see on the screen.

NOTICE
1. All transmission distances are measured using Belden 1583A CAT5e 125MHz Solid UTP 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 CAT5/6 cables, the type of VGA sources,
and the type of VGA display. The testing result shows solid UTP cables (usually in the form of
300m or 1,000ft bulk cables) can transmit a lot longer signals than stranded UTP cables (usually
in the form of fixed length patch cords). Shielded STP cables are better suited than unshielded
UTP cables. A solid UTP CAT5e cable shows longer transmission range than stranded STP CAT6
cable. For long extension users, solid UTP/STP cables are the only viable choice.
3. To reduce the interference among the unshielded twisted pairs of wires in UTP cable, you can
use shielded STP cables to improve EMI problems, which is worsen in long transmission.
4. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit
can achieve and how good is the received picture quality, the actual transmission range is
subject to one’s choice of CAT5/6 cables. For desired resolutions greater than 1080i or
1280x1024, a Cat-6 cable is recommended.
