INTRODUCTION
1. The claimed transmission distance here is subject to the grade of installed cable(s), source
device and display.
2. For over CAT5/COAX transmission, the cable(s) has to be solid, not stranded. Any keystone jack
along the transmission path will kill the transmission performance significantly!

format 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,
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.

CV-57KJ
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 50m (165ft) 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.

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.

HARDWARE INSTALLATION
1. Connect a HDMI or DVI source (such as a Blu-ray Disc player) to the transmitting unit CV-57KJ-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit CV-57KJ-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 CV-57KJ-RX.
7. Plug in 5V DC power supply unit to the power jack of the transmitting unit CV-57KJ-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!
EDID LEARNING
1. Turn off CV-57KJ-TX and disconnect the Cat.5/5e/6 between CV-57KJ-TX and CV-57KJ-RX.
2. Connect the HDMI display to "HDMI IN" on the CV-57KJ-TX with a HDMI cable.
3. Set "MODE" on the transmitting unit CV-57KJ-TX at H.
4. Turn on the CV-57KJ-TX.
5. The LED on the RJ45 of CV-57KJ-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 CV-57KJ and enjoy the experience.

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.
