INSTALLATION
The VOPEX is a Plug-and-Play device with no special configuration settings and easy installation steps:
1. Before connecting the VOPEX to the video source, make sure the video source and the monitor(s) are turned OFF.
2. Connect the video source to the DVI
port labeled “DVI Video In" on the rear
panel of the VOPEX using the
DVI-IS-3-MM cable (supplied). Longer
lengths (6, 10 and 15 foot) are also
available.
3. Connect a monitor to a DVI female port
labeled “DVI Video Out x” on the rear panel of
the VOPEX using a male-to-male DVI cable.
Note: Some monitors need to have their video
input type set manually. In this case, select
“Digital DVI” as the input type.
Note: We recommend using monitors of all
the same model, however it is not required.
DDC data is collected from all monitors but
only resolution options common to all
connected monitors are passed to the source.

connect the SA-3-MM stereo audio
cable between an audio source and
the “AUDIO IN” port on the VOPEX.
Connect any self-powered stereo
audio speakers to the “AUDIO OUT x”
ports.
5. Plug the 5VDC AC adapter into the
power jack on the rear panel.

CASCADING
For applications that require more connections than are provided for by the VOPEX-DVIS-x, one option is to connect multiple
VOPEXs in a cascaded configuration (example below). Using additional DVI-IS-xx-MM cables, connect the DVI Video Out ports
of a master VOPEX unit (master is connected to the video source) to the DVI Video In ports of additional VOPEX-DVIS-x (shown
as “Slave Unit #1” and “Slave Unit #2” below). Connect DVI-enabled displays to the cascaded VOPEXs for a larger
configuration.
Tip: Any size NTI VOPEX-DVIS(A)-x can be used interchangeably in the cascaded configuration.
Note: Additional tiers of slave units can be added, however If too many levels of slave units are added, the image on the
lower tiers may become unstable.

TROUBLESHOOTING
If the VOPEX is not working properly, please look for a solution in the list below:
PROBLEM: No video at all
SOLUTION: Check cable connections on the video source, monitor and the VOPEX. After reconnecting, if a CPU is the video
source, the CPU may need to be re-booted in order to sense the monitor connection.
PROBLEM: No video on one port
SOLUTION: Check cable connections on that port. Hot plug and/or power cycle the video source while that port is connected
PROBLEM: Some artifacts in the picture
SOLUTION: Check for any loose connection between cable and connectors. If loose, it may be necessary to reboot the CPU
to achieve a clear image.
If a solution was not found in the list above, answers may be found in the Frequently Ask Questions (FAQs) section of our website
