INTRODUCTION
The VOPEX-3V-SE-2 Video Splitter/Switch enables three monitors to display video from two CPUs. Two monitors will be
dedicated to specific CPUs, and the third monitor can be switched to display video from either CPU. An external switch will
determine which CPU is connected to the third monitor.
The VOPEX-3V-SE-2 Video Splitter/Switch is compatible with:
•VGA monitors
•SVGA monitors
•XGA monitors
•P80 video and sync timing data.
Materials Supplied with this kit:
•1- VOPEX-3V-SE-2 Video Splitter/Switch
Materials Required but not Supplied:
•2- VEXT-6 6 foot video cable
INSTALLATION
1. Turn off power to the computers and monitors.
2. Disconnect the monitor cable from a CPU and reconnect it to VID 1 on the rear of the VOPEX-3V-SE-2 (see Fig.1). A monitor
must be connected to VID 1 for the VOPEX-3V-SE-2 to work properly.
3. Connect the male end of a VEXT-6 cable to that CPU's 15HD female video output connector.
4. Connect the female end of this VEXT-6 cable to the 15HD male CPU 1 connector on the VOPEX-3V-SE-2.
5. Disconnect the monitor cable at another CPU and reconnect it to the 15HD female VID 2 connector.
6. Connect the male end of another VEXT-6 cable to the second CPU's 15HD female video output connector.
7. Connect the female end of the second VEXT-6 cable to the 15HD male CPU 2 connector on the VOPEX-3V-SE-2.
8. A third monitor may be plugged into the 15HD female VID 3 connector on the VOPEX-3V-SE-2.
9. Power up the VOPEX-3V-SE-2 Video Splitter/Switch.
10. Power up the CPUs and monitors.
CONTROL
The monitor connected to VID 3 can either display the video signal from the CPU connected to CPU 1 or from the CPU connected
to CPU 2. Selection between the two CPUs is controlled by an external, 2-position, toggle switch (not included) that connects to a
BNC connector labeled "SELECT" on the VOPEX-3V-SE-2 Video Splitter/Switch (see Fig. 2). The states of the toggle switch are
connected (signal = 24V) and disconnected (signal = 0V).

The shell of the BNC connector is ground and signal stem is the toggle line (see Fig. 3).
The switch is to be powered by an external +24VDC connected to the bare end of the line cord. The line cord wires are color
coded as follows:

STATUS LEDS
There are three LEDs on the front of the VOPEX-3V-SE-2 Video Splitter/Switch (see Fig. 2). The LEDs will indicate the state of
the VOPEX-3V-SE-2 Video Splitter/Switch.
