INTRODUCTION
The CV-147 DVI over Single CAT5 Direct Plug-in Extender extends your PC DVI
transmission distance up to 60m (200ft) with resolution 1024x768 @60Hz. With CV-147, users can
transmit high quality digital video of PC applications through one cost effective CAT-5/5e LAN cable to the
remote monitor or projector, instead of using short and expensive DVI cables. With embedded EDID
inside the extender, your PC will continue to send the digital video even when the monitor is not
connected. The user can then disconnects the monitor, place it in a remote location and reconnect it
without rebooting the operating system.
The CV-147 includes two identical units: transmitting and receiving units. The transmitting unit is
connected to your PC DVI output and the receiving unit is connected to the monitor or projector. While
successfully connected, the two LED lights on each RJ-45 connector will blink. The transmission distance
between the transmitting and receiving units can be up to 60m (200ft) under XGA (1024x768@60Hz) or
25m (80ft) under UXGA (1920x1200@60Hz). With compact size and requiring no power, CV-147 is the
most cost effective choice for bringing your impressive digital video to the remote display.

1. 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 RJ-45 connectors is recommended.
2. From time to time, there might not be enough current CV-147 can extract from DVI
+5V pin! When users encounter such a situation, LED not blinking, one typical Type A USB
to mini USB cable can help to solve this under power issue instantly!

HADWARE INSTALLATION
1. Connect CV-147-TX to your DVI source.
2. Connect CV-147-RX to your DVI display.
3. Make sure the LED blink on source and display sites! If not, please try to have enough power through
USB socket on CV-147 RX!
4. Make sure the CAT-5/5e/6 cable is tightly connected between the DVI source and the display with the
CV-147.
5. The installation is done.

1. Most of the time, power will be unnecessary for CV-147, and it behaves exactly like its
sister model CV-117! However, when encountering not enough current or voltage from
DVI connection, CV-147 offers another path, USB, to compensate the deficiency of power
supply!

NOTICE
1. The CV-147 may not be compatible with the DVI sources and displays that feature resolutions not in
the aspect ratio of 4:3, 16:9 and 16:10.
2. All DVI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C.
3. 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.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.
5. 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.
6. 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.
