INTRODUCTION
The VOPEX® Series Cat5 Video/Audio Splitter/Extender (VOPEX) is designed to enable one Video/Audio source to be
viewed and heard in 4 or 8 different remote locations. Remote video and audio devices can be located as much as 1000 feet
away from the source via Category 5 unshielded twisted-pair cable. The VOPEX-C5VA-xC1000 (x=4 or 8 port) also allows a
local video and audio device to be located near the source. Up to 4 or 8 receivers may be connected to the VOPEX.
Note: If the audio support is not present in the Remote Unit(s), please disregard all audio references.
The VOPEX will broadcast up-to-the-minute information to multiple remote monitors in real time. This high-resolution VGA
video splitter (video port expander) is the ideal solution for any application requiring the flexibility to share information with
several locations. Audio functionality using self-powered stereo speakers enhances your presentation.
The VOPEX Series Video/Audio Splitter/Extender is extremely simple to install and has been thoroughly tested to insure
reliable performance. Through the use of Category 5 unshielded twisted-pair cable it is possible to economically increase
the flexibility of a computer/home entertainment system. Here are some of the features and ways this can benefit the user:
•Allows the placement of monitors and self-powered stereo speakers/amplifiers in different remote locations
where only these parts are needed.
•Provides an additional local access port allowing the A/V source to viewed and heard locally.
•Provides crisp and clear resolution up to 2048x1536 using NTI's 1,000' remote units and 1920x1440 using NTI's
600' remote units.
•Video quality adjustment is automatic for varying lengths of CAT5 cable
•Digital transmission of audio signals reduces any loss in quality.
•Compatible with all NTI A/V switches and splitters, enabling the joining of products to create a
system that satisfies all networking needs.

LIMITATIONS
•The audio input of the VOPEX-C5VA-xC1000 is compatible with the following standard CPU audio outputs:
•Line out - typically lime green in color
•Speaker out- typically orange in color
•Headphone out
•The audio outputs of the VOPEX and the XTENDEX Receiver are 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 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 Receivers.
•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 Receivers,
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 VOPEX and XTENDEX Series 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.
Up to 600 feet of CAT5 cable can be installed between the VOPEX and any ST-C5V(A)-R-600 or ST-C5V(A)X2-R-600
Remote Unit.
Up to 1000 feet of CAT5 cable can be installed between the VOPEX and any ST-C5V(2A)-R-1000SP Remote Unit.
Use the charts on page 13 to determine what length of cable can be used for the desired resolution.

VOPEX INSTALLATION
Any or all of the 4 models of Remote Units listed on page 1 can be connected to the VOPEX and any time. The features
that are usable will depend on the models that are connected. For example, the DDC Update button will be effective for any
1000 foot Remote Units that are connected, but may not work on the 600 foot Remote Units (depending upon the features
available at the time of manufacture).
VOPEX-C5VA-xC1000
1. Make connections between the VOPEX and the audio and video source(s). (See Fig. 1.)
a) Connect the male15HD cable end of a VEXT-3 to the VGA connector on the back of the
video source.
b) Connect the female 15HD cable end of the VEXT-3 cable to the 15HD male
connector marked "Video" on the VOPEX.
c) Connect one 3.5mm stereo plug end of the SA-3-MM cable into the 3.5mm female audio
connector marked "line out", "spkr", or "headphones" on the audio source.
Notes:
If all 3 connectors are available, use the connector marked "line out".
The "line out" connector is typically lime green and may be marked with this symbol
The "spkr" connector is typically orange, and may be marked with this symbol
The "headphones" connector may be marked with this symbol
d) Connect the other 3.5mm stereo plug end of the SA-3-MM cable into the 3.5mm female stereo
audio connector marked "Audio In" on the VOPEX.

2. Connect the local user to the VOPEX.
a) Connect the cable from the local user's VGA monitor to the 15HD female connector
marked "Monitor" on the VOPEX.
b) Connect the cable from the local speakers into the 3.5mm stereo audio connector marked "Audio
Out" on the VOPEX.
3. Connect a CAT5 cable to any one of the “Cat5x” ports on the VOPEX. When properly inserted the cable end
should snap into place.
4. Repeat step 3 for each Remote Unit to be connected to the VOPEX-C5VA-x.
Note: If an RJ45 wall outlet is being used, connect the other end of the extension cable to the
RJ45 wall outlet.
WARNING: Never connect the VOPEX Extender/Splitter 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.

REMOTE UNIT INSTALLATION
ST-C5V2A-R-1000SP and ST-C5V-R-1000SP Remote Unit
1. Position the Remote Unit such that the CAT5 cable, the monitor cable, device cables, and the AC
adapter power connector can each reach the Remote Unit without putting strain on the cables.
2. Connect the monitor cable to the female 15HD video connector on the Remote Unit.
3. If the Remote Unit has audio support, connect the cable from the remote speakers to the 3.5mm
stereo audio jack with the speaker symbol on the Remote Unit. (See Fig. 7)
