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-D 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.
When the video source has an HDMI output port, connection can be made using a DVI-HD-xM-MM cable (x= 1, 2, 3 or 5 meterssold separately).
Note: If the video source and the connected monitors each support 4K resolution, 4K resolution will be displayed,
regardless of the HDMI or DVI cable type used to connect them.

3. Connect a monitor to a DVI female port
labeled “DVI-D 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.
When the display has an HDMI port, connection can be made using a DVI-HD-xM-MM cable (x= 1, 2, 3 or 5 meters-sold
separately).

6. Power up the display device(s).
7. Power up the video source.
The video from the source should now be displayed on both connected display d evices.

CASCADING
For applications that require more connections than are provided for by the VOPEX-DVI4K-2, 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-DVI4K-2
(shown as “Slave Unit #1” and “Slave Unit #2” below). Connect DVI/HDMI enabled displays to the cascaded VOPEXs for a
larger 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.

happy to assist in any way we can.
No video at all
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.
No video on one port
Check cable connections on that port. Hot plug and/or power cycle the video source while that port is connected
Some artifacts in the picture
Check for any loose connection between cable and connectors. If loose, it may be necessary to reboot the CPU
to achieve a clear image.
