INTRODUCTION
The AV-GM03G3-S1 HDMI Extender over Single Cat.X with HDBaseT, RS-232, Bi-directional IR,
Ethernet, USB & POCboosts up your video/audio transmission distance up to 100m (330ft) in HDTV
1080p with 48-bit color depth. AV-GM03G3-S1 also supports the most advanced 3D video format
complaint with HDMI specification and therefore guarantees the highest 3D video compatibility on
the market. With only one cost effective Cat.5/5e/6 cable, users can readily extend HDTV sources
from DVD players, Blu-ray Disc player, PS3, PC, and any other kinds of sources compliant with TMDS
to distant display monitors including HDMI or DVI enabled TV sets or LCD PC monitors. With the
advanced design for the latest HDMI technology, deep color video, DTS-HD or Dolby TrueHD audio,
and HDCP supports and compatibility are all further insured. This flexibility makes HDCP compliant
DVD players or PS3 transmit utmost high quality video and audio with a greater distance at the
minimal cost, when integrating several components apart. In addition, AV-GM03G3-S1 is also
equipped with bi-directional IR pass-through path and RS-232 serial port control. These bonus
features allow users to boost IR control distance up to 100m (330 ft) and makes IR control possible
through single Cat.5/5e/6 cable and USB including HDMI signals. In addition, serial port offers the
convenient path for interactive application, such as touch panels. In addition, AV-GM03G3-S1 also
supports POC (Power over Cable) which can power both units from TX or RX with power supply.
The AV-GM03G3-S1 includes two units: transmitting unit AV-GM03G3-S1-TX and receiving unit
AV-GM03G3-S1-RX. The transmitting unit is used to capture the input HDMI / DVI signals with IR
control packets and carry the signals via one cost effective Cat.5/5e/6 cable and USB. The receiving
unit is responsible for equalizing the transmitted HDMI signal and reconstructing IR and serial
control signals. AV-GM03G3-S1 offers the most convenient solution for digital signage with long
distance A/V transmission path, and with 10G transmission width ready, AV-GM03G3-S1 is ready for
your next HDMI generation and applications!

The transmission distance depends on the characteristics and quality of the cables. Higher
resolutions and longer transmission distances require low skew cables (<25ns/100m) for
best performance. Unshielded CAT6 with metal RJ45 connectors is recommended.

HARDWARE INSTALLATION
1. Connect a HDMI or DVI source (such as a Blu-ray Disc player) to the transmitting unit
AV-GM03G3-S1-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit AV-GM03G3-S1-RX.
3. Connect IR Blaster/Receiver to both TX and RX units.
4. Connect USB cable between PC/Laptop and CV-57KP-TX
5. Connect a Cat-5/5e/6 cable or USB between the transmitting and receiving units.
6. Make sure this Cat-5/5e/6 cable is tightly connected and not loose.
7. Plug in 24V DC power supply unit to the power jack of the transmitting unit AV-GM03G3-S1-TX.
8. Connect USB cable between the USB device and RX (optional).

NOTICE
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz
UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
2. Incorrect placement of IR Blaster and Receiver may result in the failure of the IR extenders.
Please check carefully before plugging in the IR extender to the respective IR sockets. Warranty
will not cover the damage.
3. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI
sources, and the type of HDMI display. The testing result shows solid UTP cables (usually in the
form of 300m [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 Cat-5e cable shows longer transmission range than stranded
STP Cat-6 cable. For long extension applications, solid UTP/STP cables are the only viable choice.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better
performance.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one
can use shielded STP cables to improve EMI problems, which is worsen in long transmission.
6. 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 Cat-5/5e/6 cables. For desired resolutions greater than 1080i or
1280x1024, a Cat-6 cable is recommended.
7. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input
#1] generally can produce better transmission performance among all HDMI inputs.
