INTRODUCTION
The XTENDEX Series CAT5 DVI Video Extender (XTENDEX) is designed to enable the video output from one digital video
source to be viewed by two users, one local and one remote. The remote monitor can be located as much as 150 feet away
from a CPU via Category 5/5e/ or 6 (CAT5) twisted-pair cable. The local user monitor will be located near the video source CPU.
The XTENDEX Series Extender is extremely simple to install and has been thoroughly tested to insure reliable performance.
Through the use of CAT5 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 a DVI-enabled monitor in a location where only these parts are needed without having the video
source there too, taking up valuable space
•Allows DVI video to be viewed by both a local and remote user (up to 150 feet away)
•Provides crisp and clear resolution up to 1920 x 1200 @ 100 feet (see page 7 for more details)
•Video quality, for varying lengths of cable, is automatically adjustable providing optimum image quality
•Transmits single link DVI-D signal over two CAT5 cables.
•Built-in surge protection.
•Only one power supply is necessary to power both the Local and Remote units.
•Supports local and remote DVI monitors.
•Compatible with DDWG DVI standard.
•HDCP Compliant
•Supports the DDC2B protocol.

LIMITATIONS
•Hot-plugging of monitors is supported provided monitors were originally connected at power-up.
•CAT5 shielded cables are not recommended for use with this extender.
PREPARATION FOR INSTALLATION
•Locations should be chosen for the monitors that also have space to connect the Remote and Local units within the distance
provided by the cables. If extension cables are needed, contact NTI for the cables required.
•The CAT5 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 monitors 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 re-connection procedures before proceeding.

INSTALLATION
Installing The Remote Unit
1. Position the Remote Unit such that the CAT5 cable and the monitor cables can each reach the Remote Unit without
putting strain on the cables.
2. Connect the monitor cable to the female DVI video connector labeled "Video Out" on the Remote Unit.
Figure 1- Connect the extended video display to the Remote Unit
Connect the CAT5 cables
Make sure the CAT5 cables (two required) have been installed in accordance with the
“Preparation for Installation” instructions on page 3. Connect the CAT5 cables to
the “Cat5” ports on the Remote Unit. (See Fig. 2.) When properly inserted the
CAT5 cable ends should snap into place.
Note: The two cables must be connected to like ports at each end of
the cables. I.e. It is important that one cable is connected between the
"VIDEO" port at the Remote Unit and the same port at the Local Unit.
The other CAT5 cable must connected between the "DDC/PWR" ports of the
Remote and Local Units. Powering the units with the cables crossed
may damage them.
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.

Installing The Local Unit
1. Make connections for a local user (optional). Connect the cable from the local user's DVI monitor to the female
DVI "Video Out" port on the Local Unit.
2. Connect the DVI-D-MM-S-2M cable between the video source and the "Video In" connector on the Local Unit.
Figure 3- Connect the XTENDEX Local Unit to the source and local video display
Connect the CAT5 Cables
Connect the CAT5 cables to the “Cat5” ports on the Local Unit. (See Fig. 4.)
When properly inserted the cable ends should snap into place. Be sure to connect
the cable from the Remote Unit "Video Cat5" port to the "Video Cat5" port on the
Local Unit and to connect the cable from the Remote Unit "DDC/PWR" port to
the "DDC/PWR" port on the Local Unit. DO NOT get them mixed up or damage
to the unit may occur.
Note: The two cables must be connected to like ports at each end of the
cables. Powering the unit with the cables crossed may damage it.
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 the AC adapter power connector to the 5VDC port on the Local Unit. Plug the AC adapter into a power outlet. The
green Power 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 Fig. 5.)
3. Turn ON the CPU and Monitors.
They should each react as if they
were directly connected to each other.
Note: The yellow LED on each RJ45
connector will illuminate when input video is
available and starts blinking when the video
is synchronized. (See Fig. 5)
Figure 5- Connect the AC adapter to the Local Unit
DDC DATA CONFIGURATION
By default, the XTENDEX is configured to transfer DDC data to the CPU (when the video source is a CPU) from the monitor
connected to the Remote Unit through the CAT5e cable attached to the "DDC/Pwr" port. In order for the CPU to receive this
data, the monitor connected to the Remote Unit must be powered ON before the CPU is powered ON.
Alternatively, the XTENDEX can be configured to transfer the DDC data from the monitor attached to the Local Unit. Follow
these steps to configure the XTENDEX:
1. Power OFF the CPU and monitors
2. Move the #1 slide switch on the front of the Local Unit up to "ON" (see Fig. 6 ).
3. Power ON the monitor connected to the Local Unit
4. Power ON the CPU.
FYI: The position of the #2 slide switch does not matter. It is not used.
