INTRODUCTION
The HDMI-C5S4IR HDMI Extender over Single Cat.X with 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. HDMI-C5S4IR also supports the most advanced 3D video format complaint
with HDMI 1.4 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 Master Audio 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, HDMI-C5S4IR 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.5/5e/6 cable including HDMI signals.
The HDMI-C5S4IR includes two units: transmitting unit HDMI-C5S4IR-TX and receiving unit HDMI-C5S4IR-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. The receiving unit is responsible for equalizing the transmitted HDMI signal
and reconstructing IR signals. The transmission distance between the sending and receiving units can be up to 60m
(200ft) at HD 720p or 1080i; or 40m (130ft) at 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
● HDMI 1.4a compliant [3D video]
● Extend the transmission up to 60m (200ft) from the HDMI source at HD 1080i or 720p 24-bit
● Extend the transmission up to 40m (130ft) from the HDMI source at Full HD 1080p 24-bit
● Extend the transmission up to 20m (65ft) from the HDMI source at Full HD 1080p 36-bit
● HDCP 1.1 compliant
● Minimize the cable skew by adjustable 8-level equalization control
● Pure unaltered uncompressed 7.1ch digital HDMI over Cat.5/5e/6 cable transmission
● DTS-HD Master Audio and Dolby TrueHD high bit rate audio support
● Support full frequency IR signal from 20kHz to 60kHz
● Bi-directional IR pass-through
● Allows cascading
● Wall mounting housing design for easy and robust installation
● Perfectly integrated with other HDMI over Cat.X series products
The claimed transmission distance here is subject to the grade of installed cable(s), source
device and display.
For over CAT.X 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 HDMI-C5S4IR-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit HDMI-C5S4IR-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 HDMI-C5S4IR-RX.
7. Plug in 5V DC power supply unit to the power jack of the transmitting unit HDMI-C5S4IR-TX.
8. If you see flickering or blinking image on the display, please adjust the rotary control switch to improve the cable
skew. 0 stands for the strongest HDMI signal level for longest possible transmission length while 7 stands for
the weakest HDMI signal level for short transmission length. Please adjust the signal level from 7 to 0 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!
EDID LEARNING
1. Turn off HDMI-C5S4IR-TX and disconnect the Cat.5/5e/6 between HDMI-C5S4IR-TX and HDMI-C5S4IR-RX.
2. Connect the HDMI display to "HDMI IN" on the HDMI-C5S4IR-TX with a HDMI cable.
3. Set "MODE" on the transmitting unit HDMI-C5S4IR-TX at H.
4. Turn on the HDMI-C5S4IR-TX.
5. The LED on the RJ45 of HDMI-C5S4IR-TX will dim and light again, which indicates the EDID learning procedure is
complete.
6. Unplug the HDMI cable from the display and follow the instruction in [Hardware Installation] to set up the
HDMI-C5S4IR and enjoy the experience.
7. When following the [Hardware Installation] leave mode setting on H as changing it will default the EDID.

NOTICE
1. When adjusting the signal level on the Receiving 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 Cat5/5e/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.
