NTI XTENDEX Wall Mount Extenders
INTRODUCTION
The XTENDEX Series Wall Mount VGA Video and Stereo Audio Extender (XTENDEX) is designed to enable the VGA video and
stereo audio signals from one CPU to be viewed and heard by two users, one local and one remote. The remote user can be
located as much as 500 feet away via Category 5 unshielded twisted-pair cable. The local user will be loc ated near the CPU.
The XTENDEX Series Wall Mount VGA Video and Stereo Audio Extender is extremely simple to install and has been thoroughly
tested to insure reliable performance. Through the use of Category 5 cable it is possible to economical ly increase the flexibility of
a computer system. Here are some of the features and ways this can benefit any workplace:
• Allows the placement of comp uter monitor and speakers in a location where only these parts are needed without having
the CPU there too, taking up valuable space
• Allows a CPU video and audio signal to be accessed by both a local and remote user (up to 500 feet away)
• Compatible with VGA, SVGA, and XGA systems
• Provides crisp and clear resolution up to 1024 x 768 @ 500 feet (see page 8 for more details)
• Compatible with all NTI switches and splitters, enabling the joining of products to create a system that
satisfies all networking needs
• Video quality adjustment, for varying lengths of cable, is automatic providing optimum image quality
• Digital transmission of au dio signals reduces any loss in quality

LIMITATIONS
• Hot-plugging of devices is supported provided devices were originally connected at power-up.
• The audio input of the XTENDEX is compatible with the following standard CPU audio outputs:
• Line out - typically lime green in color
• Speaker out- typically orange in color
• Headphone out- typically located on the CD-ROM
• The audio output of the XTENDEX is compatible with self-powered stereo speakers.
PREPARATION FOR INSTALLATION
• Locations should be chosen for the monitors and speakers that also have 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 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, etc.).
• All cables should be installed in such a way that they do not cause stress on their connections to the equipment. Exten ded
lengths of cable hanging from a connection may interfere with the quality of that connec tion. Secure cables as needed to
minimize this.
• Properly shut down and disconnect the power from the CPU, monitors, and speakers 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.
Note: CAT5 connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series products
should not be run underground, outdoors or between buildings.
!
WARNING: Outdoor or underground runs of CAT5 cable could be dangerous and will void the warranty.

INSTALLATION
Installing The Local Unit
Connect The CAT5 Cable
A CAT5 cable with an RJ45 connector wired straight through (see specification on page 10) shou ld extend from a UL
Listed 2 gang electrical box at least far enough to make connection to the RJ45 connector on the back of the Local Unit
(see Fig. 1). The outlet box must be at least 2 inches deep.
1. Connect the CAT5 cable to the Local Unit. When properly inserted the cable end should snap into place.
!
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.
2. Secure the Local Unit to the 2 gang outlet box using the 6-32X1/2" Phillips Flat Head screws (4) provided.

Installing The Remote Unit
The Remote Unit can either set on a desk near the monitor and speakers to be connected, or it can be mounted to a vertical
surface using the wall mount brackets provided.
Attach Wall Mount Brackets
The two wall mount brackets can be secured to the Remote Unit using the four #4-40 x 1/4" screws provided (see Fig. 4). With
the brackets attached, mount the Remote Unit to any desired surface using suitable hardware (not included). Be sure to position
the Remote Unit such that the CAT5 cable, the monitor cable, and the speakers cable can each reach the Remote Unit without
putting strain on the cables.

Plug-in and Power Up
1. Plug the power cord from the monitors into power outlets. Also power up the speakers if they have external power supplies.
2. Connect the 12VDC AC adapter power connector to the 12VDC port on the Local Unit (see Fig. 7). Plug the AC adapter into
a power outlet. The green LED on the RJ45 connector of the Remote Unit and the power LED on the wallplate of the Local
Unit should each illuminate, indicating that a proper power connection has been made to them (see Fig. 6). (The Remote
Unit is powered by the Local Unit through the CAT5 cable.)
3. Turn ON the CPU and Monitors.
They should each react as if they
were directly connected to each
other.

VIDEO QUALITY
Automatic Video Quality Adjustment
Video quality adjustment is done automatically to assure the image is as clear as possible.
Note: When the cable is longer than 300 feet some colored lines can be seen at the black-to-white transitions. This is a
normal behavior and is caused by the different twisting rates of each pair of wires in the CAT5 cable.
