INTRODUCTION
The AV-GM04A3-S1-IR HDMI extender over IP with IR and RS-232 boosts up your video/audio
transmission distance up to 100m (330ft) in HDTV 1080p format. 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. Besides AV-GM04A3-S1-IR also supports HDCP and 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-GM04A3-S1-IR
is also equipped with IR pass-through path and RS-232 serial port control.
The AV-GM04A3-S1-IR is also a HD video distribution solution for digital signage. With SP-5022I,
AV-GM04A3-S1-IR can also support s a 10 layer “daisy-chain” for up to 1000M or even longer.

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.
CAUTION!

NOTICE
1. When adjusting the signal level on the receiver unit, please dial the rotary control switch 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!
2. Wrongly insert IR blaster and IR receiver to wrong 3.5mm infrared sockets may result in the
failure of the IR extenders. Please check carefully before plugging in the IR extender to the
respective IR sockets.
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 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.
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.
