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.

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.

VIDEO QUALITY ADJUSTMENT
VOPEX-C5VA-xC1000
When powering ON the VOPEX-C5VA-xC1000, video quality adjustment is done automatically to assure the image is as
clear as possible. Once the VOPEX is up and running, an adjustment may need to be made to the resolution setting of the
CPU, due to variations in compatible resolutions in the monitors connected to the Remote Units. To make sure the CPU has
updated EDID data to choose from, press the “DDC Update" button. (See Fig. 6). The VOPEX will compare EDID tables
from each monitor connected to a 1000 Series Remote Unit and supply the compatible resolutions to the CPU as available
options. Once that has been done, select the desired resolution from the available settings in your operating system.
Note: The 600 Series extenders do not support the DDC Update feature as of this printing.
Figure 6- DDC Update button for EDID data update
More About DDC
The recording and DDC transfer of EDID data from the monitor(s) enables the CPU to know what resolution settings are
compatible with the monitor(s) connected. Once this data is provided to the CPU, your graphics card will either
automatically update to the best resolution available (some models of graphic cards, not all), or you will need to choose from
the available settings. Bear in mind, the choices of settings compatible with the monitors are not necessarily all going to be
usable. If the length of CATx cable in your installation is too long for the selected resolution, the image at the Remote Unit
monitor may not be viewable. Be sure to select a resolution setting that your installation will support. For supported
combinations, see the chart on page 13.
Video quality may need to be re-adjusted if any of the following situations occur:
•A CAT5 cable is replaced, for any reason
•A new XTENDEX Remote unit is connected to the system
•CAT5 cable becomes disconnected from the VOPEX or any of the Remote Units
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.
Fine Video Quality Adjustment
ST-C5V(A)-R-1000 Video-Only Extenders
It is possible that on initial startup the image on the monitor will not be as crisp as the image normally is or the colors may
not appear as they normally would. The colors may also be skewed, or out of alignment as they appear on the monitor.
This is due to the frequency characteristics of the CAT5 cable and differences in cable types that can be used (i.e. shielded
vs. unshielded cable and CAT5 vs. CAT6 cable). Models without keyboard support include a “Mode” button for the
following functions:
¾fine adjustment of the general video quality
¾fine adjustment of color skew (alignment of red, green, and blue signals on the monitor)
¾update DDC information between the monitor(s) and CPU
Test Patterns for Color Skew Adjustment
To verify the need for and effect of color skew adjustment using a test pattern specifically designed for
your display setting, browse the CD this manual was found on and click on the “test-pattern-nXm.pdf”
file that matches your current video resolution. Follow the instructions below to make adjustments as
needed.

NTI VOPEX SERIES SPLITTER/EXTENDER

Depending upon what mode the XTENDEX is in, the “+” (plus)
and “-“ (minus) buttons can be pressed to make the adjustment.
A “Mode” LED is provided to indicate what characteristic is being
changed.
Figure 7- Video Adjustment buttons
Note: The VOPEX and Remote Units must be connected and communicating in order for the mode button to
function.
The chart below describes the video quality changes that can be made with the Mode button and the associated indication
provided by the Mode LED.

Seventh Press Dark (LED OFF)- repeat cycle
When adjusting color skew, a momentary press of either the “+” (plus) or “-“ (minus) buttons button will make a minor change
in the image. If either button is pressed and held, the changes made will be gradual and continuous. Ultimately, the image
quality should improve to a satisfactory level. Once the adjustment is made, it should not be necessary to change it again,
as the new settings are stored in memory and become the default settings with each startup.
If the image still lacks definition, configuration adjustments may need to be made to the attached video display equipment.
This is a problem most often seen in LCD displays. Check the manual for the equipment having the poor display and look
for an "auto-adjust" or "auto-configure" feature. Once this is done, you may need to repeat the Video Adjustment
procedure described above to achieve the best image.
Note: After pressing the Mode button,
if there is a pause in button activity
for 30 seconds or more, the feature
will return to a power-ON state with
the LED OFF.

ST-C5V(X2)-R-600 Video-Only Extenders
Video quality adjustment of the monitor connected to an ST-C5V-R-600 Remote Unit or ST-C5VX2-R-600 is performed
manually at the Remote Unit.
It is possible that on initial startup the image on the monitor will not be as crisp as the image normally is. This is due to the
frequency characteristics of the CAT5 cable. It may be necessary to press the "+" or "-" buttons on the Remote Unit (see
Fig. 8) until the image is crisp and clear. Press the "+" button if the image is not crisp and clear enough. Press the "-"
button if the image has been over-corrected (such that horizontal lines appear to trail or shadow at the edge of an open
window). A momentary press of either button will make a minor change in the image. If either button is pressed and held,
the changes made will be gradual and continuous. Ultimately, the image quality should improve to a satisfactory level.
Once the adjustment is made, it should not be necessary to change it again as the new settings are stored in memory and
become the default settings with each startup.
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.
