INTRODUCTION
The VOPEX-2V/4V/8V/16V-H video port splitter enables two, four, eight, or sixteen monitors to be driven from the same video
port.
•These units have a bandwidth of 150 MHz enabling them to support high resolution video – up to 1900x1200 with no
degradation.
•These units are compatible with VGA, SVGA, and XGA monitors.
•The VOPEX 2V/4V/8V/16V-H is also DDC compatible on OUTPUT-1 and only on OUTPUT-1.
•VOPEX-2V/4V/8V/16V-H video port splitters can be cascaded to drive up to 100 monitors by interconnecting multiple units
(see page 3 for illustration).
Option:
VOPEX with UL Listed power supply- to order add -UL to model number (VOPEX-2V/4V/8V/16V-H-UL)
VOPEX with audio support added (non-UL)- to order add A to the model number (VOPEX-2VA-H)(2, 4, and 8 port models only)

INSTALLATION
1. Turn OFF power to CPU and monitor(s).
2. Disconnect the monitor cable at the CPU and reconnect it to OUTPUT 1 on the rear of the VOPEX. OUTPUT 1 must be
connected to a monitor for the unit to operate properly. It is labeled as such (see Fig. 1).
Note: If a monitor with DDC support will be used, it must be connected to OUTPUT-1. All other monitors must support
the highest video resolution supported by the DDC monitor connected to OUTPUT-1.
3. Install the 15HD male end of the NTI-supplied video interface cable into the CPU’s video output connector.
4. Install the 15HD female end of this cable into the INPUT connector of the VOPEX.
5. Additional monitors may be plugged into the remaining OUTPUT(s) as required.
6. Plug in VOPEX power cord and turn unit ON.
Note: VOPEX-xV-H-UL model does not have power switch. Just plug in AC adapter to power up.
7. Turn ON power to CPU and monitor(s).

AUDIO SUPPORT
Models with audio support (i.e. VOPEX-2VA-H) can additionally be connected to an audio source. A 3.5mm jack is provided for
connection to the audio source using the 3 foot audio cable (provided). Outputs are provided for connection of self-powered
stereo speakers, headphones, and/or ear buds. Additional sets of stereo speakers, headphones, and/or ear buds can be
connected when multiple VOPEX splitters are cascaded.
Notes:
The audio port on a CPU may be marked "line out", "spkr", or "headphones". If all 3 jacks are
available, use the jack marked "line out".
The "line out" jack is typically lime green and may be marked with this symbol
The "spkr" jack is typically orange, and may be marked with this symbol
The "headphones" jack may be marked with this symbol

CASCADING
Up to 100 monitors can be driven using a single CPU by cascading multiple VOPEX splitters as shown in Fig. 2. Other than
additional VOPEX splitters, the only additional hardware required are VEXT-THN-xx cables with lengths sufficient to reach each of
the monitors to be connected and for connecting the VOPEX splitters. (For cascading speakers using VOPEXs with audio
support, additional SA-xx-MM cables will be required (see page 1)).
Note: If a DDC monitor is to be used in a cascaded application, it must be connected to OUTPUT 1 of the VOPEX
connected to the master VOPEX at OUTPUT 1 (labeled "SLAVE #1 in Fig. 2).
