NTI XTENDEX 300 Foot DVI Video and IR Extender

INTRODUCTION
The XTENDEX Series ST-C6DVI-IR-300 CAT6 DVI and IR Extender (XTENDEX) is designed to enable the video output from one
digital video source to be viewed by a remote user. Each video extender consists of a local unit that connects to an DVI video
source and optional IR emitter, and a remote unit that connects to an DVI display and optional IR receiver as much as 300 feet
away via Category 5e,6, 6a or 7 twisted-pair cable.
The XTENDEX Series Extender is extremely simple to install and has been thoroughly tested to insure reliable performance.
Through the use of CAT5e/6/6a/7 (CATx) cable it is possible to economically increase the flexibility of a computer system. Here
are some of the features and ways this can benefit any workplace:
Allows the placement of an DVI-enabled monitor in a location where only these parts are needed without having the
video source there too, taking up valuable space
Allows digital video to be viewed and heard by a remote user (up to 300 feet away)
Provides crisp and clear computer resolution to 1920 x 1200 and HDTV resolutions to 1080p (see page 8 for more
details)
Transmits DVI signal over one CATx cable.
Only one power supply is necessary (Power supply can be connected to either the local or remote unit.)
Supports a DVI monitor.
HDCP 1.2 compliant
Supports the DDC2B protocol.
Supports 480p, 720i/p and 1080i/p video formats

LIMITATIONS
The use of CAT5e unshielded or all shielded CATx cabling will reduce the maximum distance and resolution.
PREPARATION FOR INSTALLATION
Locations should be chosen for the monitor that also has space to connect the Remote unit within the distance provided by
the cables. If extension cables are needed, contact NTI for the cables required.
The CATx cables must be run to the locations where the Remote and Local units will be connected. Be careful to route the
cables away from any sources of magnetic fields or electrical interference that might reduce the quality of the video signal
(i.e. AC motors, welding equipment, fluorescent lighting, etc.).
All cables should be installed in such a way that they do not cause stress on their connections to the equipment. Extended
lengths of cable hanging from a connection may interfere with the quality of that connection. Secure cables as needed to
minimize this.
Properly shut down and disconnect the power from the video source and monitor to be separated. If other equipment is
involved whose connections are being interrupted, be sure to refer to the instruction manuals for that equipment for proper
disconnection and reconnection procedures before proceeding.
WARNING: The CATx connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series
products must be wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc.) The use of a CROSSOVER CABLE will
damage the extender and void your warranty.

INSTALLATION
Installing The Remote Unit
1. Position the Remote Unit such that the CATx cable and the monitor cables can each reach the Remote Unit without
putting strain on the cables.
2. Connect a DVI-IS-xx-MM to the female DVI video connector labeled "DVI Out" on the Remote Unit.
Figure 1- Connect the extended video display to the Remote Unit
Installing The Local Unit
Connect a DVI-IS-xx-MM between the video source and the "DVI Video In" connector on the Local Unit.

Connect the CATx Cables
Connect the CATx cable between the
“CATx” ports on the Local and Remote Unit.
(See Figure 3.) When properly inserted the
cable ends should snap into place.
WARNING: The CATx connection cable used
between NTI XTENDEX Series Local and
Remote or any XTENDEX Series products
must be wired straight through (pin 1 to pin 1,
pin 2 to pin 2, etc.) The use of a CROSSOVER
CABLE will damage the extender and void
your warranty.
Figure 3- Connect CATx cable
WARNING: Never connect the XTENDEX to an Ethernet card, Ethernet router, hub or switch or other Ethernet RJ45
connector of an Ethernet device. Damage to devices connected to the Ethernet may result.
Plug-in and Boot Up
1. Plug the power cord from the monitor into the power outlet.
2. Connect an AC adapter power connector to the 24VDC port on the Remote Unit or the Local Unit. Plug the AC adapter into a
power outlet. The green LED on the RJ45 connector of both the Remote and Local Units should illuminate, indicating that a
proper power connection has been made to them. (See Figure 3) The yellow LED on both the Local and Remote Units
should illuminate indicating there is communication between them.
3. Turn ON the video/audio source and video display device. The source and display device should each react as if directly
connected to each other.

The AC adapter can be
connected to either the
Local Unit OR the
Remote Unit to make the

INFRARED CONTROL
The ST-C6DVI-IR-300 includes ports for connecting an infrared emitter and receiver (included) to work in conjunction with the IR
remote control used to operate the video source. Connect the receiver to the “IR IN” port on the Remote Unit and the emitter to
the “IR OUT” port on the Local unit. Position the end of the receiver such that the signal from the remote control can easily reach
the IR sensor. Position the end of the emitter such that the extended signal can be sent to the video source.
