LIMITATIONS
• The audio input of the VOPEX-C6DVIA-(LA)-4 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 outputs of the VOPEX and the XTENDEX Remote Unit are compatible with self-powered stereo speakers.
• For best results, use CAT6/6a cable when audio support is required. CAT5e/7 cable supports audio only to 150ft.
PREPARATION FOR INSTALLATION
• Locations should be chosen for the monitors and speakers that also have space to connect the VOPEX and XTENDEX
Remote 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 VOPEX and XTENDEX Remote 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.). NOTE: If CAT5 cable is already installed in the
wall and there are RJ45 wall outlets, it will be necessary to obtain male-to-male straight through connection cables long
enough to reach from the wall outlets to the connection locations of the VOPEX and XTENDEX Remote Units.
• A properly grounded, polarized, and preferably surge-protected 120V or 240V electrical outlet (depending on the AC
adapter being used) must be installed close enough to the connection location of the VOPEX and XTENDEX Remote
Units, monitors, stereo speakers, and CPU to plug them into.
• 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 all devices 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.

INFRARED CONTROL
The VOPEX includes a port for connecting an infrared emitter that when used with an infrared receiver (connected at the
Remote Unit end) will work in conjunction with the IR remote control used to operate the video/audio source. Connect the
receiver to the “IR IN” port on the Remote Unit and the emitter to the “IR OUT” port on the VOPEX. 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 signal source.
Note: The IR Emitter and Receiver work within a frequency range of 30-60kHz. Check the
specifications for the device you are extending to make sure the VOPEX and XTENDEX will work
with it.

PLUG-IN AND BOOT UP
1. Plug the power cord from each video device and the power supply for each audio device into a power outlet.
2.
Connect the 24VDC 2.5A AC adapter power connector to the power port on the VOPEX (16-port models have a
country-specific line cord).
No AC adapter is required at the Remote Unit. The Remote Unit will be powered through the CATx cable from the VOPEX.
3. Plug the AC adapter/power cord into a power outlet. The green LED on the VOPEX and the green LED on the RJ45
connector of each XTENDEX Remote Unit should illuminate, indicating that a proper power connection has been made to
them. (See Figure 4)
Figure 6- Connect the AC adapter to a VOPEX
4. Turn ON the audio and video source(s), stereo speakers, and monitors. They should react as if they were directly
connected to each other.
Note: The yellow LED on the RJ45 connector of each XTENDEX Remote Unit will illuminate anytime data traffic is
passing between the VOPEX and the XTENDEX, indicating proper CATX cable connection and communication.
(See Figure 4)

CASCADING
The VOPEX-C6DVI-LA-4 can be cascaded for larger configurations and greater flexibility. By connecting the “DVI Video
Out” port (models with Local Access feature only) on one VOPEX with the “DVI-Video In” port on another VOPEX (4, 8, or
16 port, doesn’t matter what size), your configuration can increase in size with a minimum of effort. Models with audio
support can have the audio from your source expanded in the same fashion. Connect as many or as few extenders as your
cascaded configuration allows.
Note: Only models with the Local Access feature have the flexibility of being cascaded, but the VOPEX at the end
does not require the Local Access feature to receive and extend the video/audio signals (as seen in the image
below).
