INTRODUCTION
The CV-117 DVI Passive Extender over Single Cat.X DVI Passive Extender over Single Cat.X
extends your PC DVI transmission distance up to 30m (100ft) with resolution 1024x768 @60Hz. With
CV-117, 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-117 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 RJ45 connector will blink. The transmission distance
between the transmitting and receiving units can be up to 30m (100ft) under XGA (1024x768@60Hz) or
15m (50ft) under UXGA (1600x1200@60Hz). With compact size and requiring no power, CV-117 is the
most cost effective choice for bringing your impressive digital video to the remote display.
FEATURES
●DVI 1.0 compliant
●Extends the transmission length from the sources up to 30m (100ft) under XGA (1024x768@60Hz) or
15m (50ft) under WUXGA (1920x1200@60Hz)
●Identical units work at both transmitting and receiving end
●Easy to install
●No external power required
●Compact size
●Direct plug-in
●Perfectly integrated with other DVI over Cat.X series products
PACKAGE CONTENTS
●2x CV-117
●1x User Manual
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.

HARDWARE INSTALLATION
1. Connect one of the CV-117 to your DVI source.
2. Connect the other CV-117 to your DVI display.
3. Make sure the CAT-5/5e/6 cable is tightly connected between the DVI source and the display with the
CV-117.
4. The installation is done.

NOTICE
1. The CV-117 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.
