INTRODUCTION
The AV-GM04D3-S1 HDMI Extender over Dual Cat.X with RS-232 & Bi-directional IR boosts up
your video/audio transmission distance up to 60m (200ft) in HDTV 1080i format, 40m (130ft) in
HDTV 1080p format, and 20m (65ft) in HDTV 1080p with 36 bit color depth. With two cost effective
LAN 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/DVI enabled TV sets or LCD PC monitors. With the state-of-the-art Silicon Image chipsets
equipped, 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-GM04D3-S1 is also equipped with bi-directional IR pass-through
path. This bonus feature allows users to boost IR control distance up to 100m (330 ft) and makes IR
control possible through only single CAT-5 type cable including HDMI signals. Furthermore,
AV-GM04D3-S1 is equipped with a popular serial control path RS-232. With high definition digital
signal and serial control, AV-GM04D3-S1 makes your digital signage application with the upmost
performance in pure digital domain.
The AV-GM04D3-S1 includes two units: transmitting (AV-GM04D3-S1-TX) and receiving
(AV-GM04D3-S1-RX) units. The transmitting unit is used to capture the input HDMI/DVI signals with
IR control packets and serial port, such as COM1 to carry the signals through one RJ45 connector
into cost effective Cat-5/5e/6 cable. The receiving unit is responsible for equalizing the transmitted
HDMI signal, reconstructing IR signals and receiving serial command. The transmission distance
between the sending and receiving units can be up to 60m (200ft) under HD (720p/1080i) or 40m
(130ft) under Full HD (1080p). With an 8-level equalization rotary control on the receiving unit, users
can adjust the equalization strength to the received HDMI signals accordingly, and therefore
optimize the transmission distance between source and destination.
FEATURES
●Support HDMI Deep Color & full 3D
●Extends the transmission distance up to 60m (200ft) from the sources under 1080i or 720p
●Extends the transmission distance up to 40m (130ft) from the sources under 1080p
●Provides independent DDC channel, fully HDCP compliant
●Minimizes the cable skew by adjustable 8-level equalization rotary control switch
●Support bi-directional full bandwidth of IR signal, 20KHz ~ 60KHz
●Pure unaltered uncompressed 7.1ch digital HDMI over CAT5/6 cable transmission
●Supports serial port RS-232 [TX & RX] control
●Wall mounting housing design for easy and robust installation
●Perfectly integrated with other HDMI over Cat.X series products

The length 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.
The claimed transmission distance here is subject to the grade of installed cable(s), source device
and display.
For over Cat.X/COAX transmission, the cable(s) has to be solid, not stranded. Any keystone jack
along the transmission path will kill the transmission performance significantly!

HARDWARE INSTALLATION
1. Connect a HDMI or DVI source (such as a Blu-ray Disc player) to the transmitting unit
AV-GM04D3-S1-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit AV-GM04D3-S1-RX.
3. Connect IR Blaster/Receiver to both TX and RX units.
4. Connect a Cat-5/5e/6 cable between the transmitting and receiving units.
5. Make sure this Cat-5/5e/6 cable is tightly connected and not loose.
6. Plug in 5V DC power supply unit to the power jack of the receiving unit AV-GM04D3-S1-RX.
7. Plug in 5V DC power supply unit to the power jack of the transmitting unit AV-GM04D3-S1-TX.
8. If you see flickering or blinking image on the display, please adjust the rotary control switch to
improve the cable skew. MAX stands for the strongest HDMI signal level for longest possible
transmission length while MIN stands for the weakest HDMI signal level for short transmission
length. Please adjust the signal level from MIN to MAX and stop turning the rotary switch
whenever the audio/video is playing normally. Inappropriate signal level setting may cause
overpowering issue that would shorten the product life significantly!

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.
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.

NOTICE
1. When adjusting the signal level on the receiver unit, please dial the rotary control switch from
MIN to MAX or F to 8 and stop turning the rotary switch whenever the audio/video is playing
normally. Inappropriate signal level setting may cause overpowering issue that would shorten
the product life significantly!
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. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to
retrieve and provide DVI or HDMI display EDID information.
4. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz
UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
5. 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 330m [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.
6. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better
performance.
7. 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.
8. 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.
9. 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.
