INTRODUCTION
The CV-57H HDMI Extender over Single Cat.X with Direct Plug-in Receiver boosts up your video/
audio transmission distance up to 25m (80ft) in HDTV 1080i format. With only one cost effective LAN
cable, users can directly plug the receiver in to 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. This cost effective exibility makes HDCP compliant
DVD players or PS3 transmit high quality video and audio with a greater distance at the minimal cost,
when integrating several components apart.
The CV-57H includes two units: transmitting (CV-57H-TX) and receiving (CV-57H-RX) units. The
transmitting unit is used to capture the input HDMI/DVI signals and carry the signals through one RJ45
connector into one cost effective Cat-5/5e/6 cable. The transmission distance between the sending and
receiving units can be up to 25m (80ft) under HD (720p/1080i) or 15m (50ft) under Full HD (1080p). With
direct plug-in to the HDTV, users do not need to have to nd a power outlet for the traditional HDMI over
CAT5 receiver and can save an HDMI cable with ease of use.
FEATURES
● State-of-the-art Silicon Image (founder of HDMI) chipset embedded for utmost compatibility and
reliability
● HDMI 1.3c compliant
● HDCP 1.1 compliant
● Extends the transmission length up to 25m (80ft) from the HDMI sources under HD resolution (1080i or
720p)
● Extends the transmission length up to 15m (50ft) from the HDMI sources under Full HD resolution
(1080p)
● Wall mounting housing design for easy and robust installation
● Pure unaltered uncompressed 7.1ch digital HDMI over UTP
● cable transmission
● Perfectly integrated with other HDMI over Cat.X series products
i
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.

Note for Auto EDID (Extended Display Identication Data) learning
1 Please connect the display which you want to read EDID with a HDMI cable to the transmitter's
HDMI-IN and turn Mode to 7 so the TX can learn the EDID information from the connected HDTV.
The LED on the RJ45-OUT of TX will dim and light again in a few seconds, which indicates the
EDID learning process is completed.
2 Turn Mode clockwise from Mode 7 to Mode 0 or Mode 1 for desirable audio setting and enjoy the
experience. DO NOT let the rotary arrow pass by Mode 6 which will erase the EDID just learned
and restore the default EDID.
3 If use Mode 6 EDID(1080p),turn Mode clockwise from Mode 6 to Mode 0~4.
If use Mode 5 EDID(1080p),turn Mode anticlockwise from Mode 5 to Mode 0~4.

INSTALLATION
1. Connect your HDMI/DVI source (such as a Blu-ray Disc player) to the transmitting unit CV-57H-TX.
2. Plug-in the receiving unit CV-57H-RX to your HDMI display (such as a HDTV or a projector).
3. Connect your CAT-5/5e/6 LAN cable between the transmitting and receiving units.
4. Make sure your CAT-5/5e/6 LAN cable is tightly connected and not loose.
5. Plug in 5V DC power cord to the power jack of the transmitting unit CV-57H-TX.
EDID LEARNING
1. Turn on CV-57H-TX.
2. Turn the Mode of CV-57H-TX counterclockwise from 0 (for surround sound) or 1 (for stereo) to 7.
3. Use a HDMI cable to connect CV-57H-TX & the display (better not connect to video source). The
LED on the RJ45 of CV-57H-TX will dim and light again, which indicates the EDID learning process is
nished.
4. Turn the Mode of CV-57H-TX clockwise from 7 to 0 (for surround sound) or 1 (for stereo). The most
important thing is don't let the rotary arrow pass through 6 which will erase the EDID just learned and
restore to default EDID.
5. Connect CV-57H-TX and the video source through a HDMI cable and enjoy the experience.

NOTICE
1. When adjusting the signal level on the receiver unit, please dial the rotary control switch 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 signicantly!
2. If the DVI or HDMI device requires the EDID information, please use CV-1001 or CV-5005H EDID
Reader/Writer to retrieve and provide DVI or HDMI display EDID information.
3. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
4. 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.
5. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended.
6. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can
use double shielded STP cables to improve EMI problems, which is worsen in long transmission.
7. Because the quality of the category 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.
8. 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.
