INSTALLATION
Turn OFF power to the CPU that will be connected to the VOPEX before connecting or disconnecting any cables.
WARNING!If power to the CPU is not turned OFF before connecting or disconnecting cables, damage to the CPU
may result.
Connect the CPU
1. Connect a VEXT-3 cable from the video port of the CPU to the male 15HD port labeled "VIDEO IN" on the VOPEX.
2. Connect the purple male 6 miniDIN connectors of the VVKINT-3-MM cable from the keyboard port of the CPU to the female 6
miniDIN port labeled "KYBD FROM CPU" on the VOPEX.
3. Connect the green male 6 miniDIN connectors of the VVKINT-3-MM cable from the mouse port of the CPU to the port
labeled "MOUSE FROM CPU" on the VOPEX.
Connect the Monitor(s)
1. Connect a monitor to "MONITOR 1" on the back of the VOPEX (see figure above).
NOTE: A monitor must be connected to the port labeled "VGA MON1" for the monitor device driver to function properly.
2. Connect any other monitors to any of the other "MONITOR x" ports on the back of the VOPEX.
Connect the Mouse(Mice)
1. Connect a mouse to the "MOUSE1" port on the back of the VOPEX (see figure above).
2. Connect any remaining mice to other "MOUSEx" ports on the back of the VOPEX. Note which port number each user is
attached to.
Connect the Keyboard(s)
1. Connect a keyboard to the port labeled "KYBD1" on the rear of the VOPEX (see figure above).
2. Connect other keyboards to KYBDx ports on the VOPEX, making sure that each user is connected to a keyboard port and a
mouse port with the same number.
Connect the AC adapter
Connect the AC adapter to the VOPEX and plug it into an AC power outlet.

SPECIAL MOUSE CONSIDERATIONS
NOTE: If the VOPEX is power-cycled with the CPU ON, the mouse driver must be reloaded for mice to function properly.
1. Hot plugging limitations
A. Any mouse to be emulated must be connected to "MOUSE1" at VOPEX power-up. e.g. If at a later time the user wants
to hot-plug 3-button mice, a 3-button mouse must have been connected to "MOUSE1" at VOPEX power-up.
B. If no mice were connected at power-up, VOPEX will default to standard 2-button mode.
2. ALPS Glidepoint
A. For “taps” function to work properly, ALPS Glidepoint must be connected to "MOUSE1" at power-up and ALPS Mouse
Driver must be used.
B. Some Microsoft mice may conflict with ALPS Glidepoint. If a problem occurs, connect ALPS to "MOUSE1"
and use a regular Microsoft mouse driver. NOTE: ”taps” will not function in this configuration.
3. Microsoft Ballpoint
A. Do not connect Ballpoint to "MOUSE1" if other types of mice are to be used in the VOPEX. If Ballpoint is connected to
"MOUSE1", all other mice must also be Ballpoints.
B. At least one Ballpoint must be connected to VOPEX when powering up in order for hot-plugging to work for other
Ballpoints.
4. 3-button Mice
A. A 3-button mouse must be connected to "MOUSE1" for any mice to work as 3-button.
5. Microsoft IntelliMouse
A. All mice connected to VOPEX must be IntelliMouse to be able to use the IntelliMouse.
B. The IntelliMouse cannot be hot-plugged.
POWER-UP SEQUENCE
NOTE: Any cable longer than 100 feet for the keyboard requires an AC adapter. If using a COMPAQ keyboard, the
adapter and the VOPEX must be powered up at the same time!
1. Turn ON power to the VOPEX.
2. Turn ON power to the monitor(s).
NOTE: The monitor(s) MUST be turned ON before the CPU.
3. Turn ON power to the CPU.
Keyboards and mice are powered by the VOPEX.
POWER-DOWN SEQUENCE
1. Turn OFF power to the CPU.
2. Turn OFF power to the VOPEX.
DIAGNOSTIC INFORMATION
At power up, the VOPEX uses the "User x" LEDs on the front panel to report some status. The sequence of events is as follows:
1. When unit is first powered, the LED state is indeterminate.
2. All LEDs are turned OFF, then flashed ON and OFF to indicate processor activity.
3. One LED for each keyboard detected is flashed ON and OFF.
4. One LED for each mouse detected is flashed ON and OFF.
5. The LEDs are left in the proper mode status (see “MODES OF OPERATION" on page 4).

MODES OF OPERATION
This VOPEX has three basic modes of operation: INSTANT AUTO. DELAYED AUTO, and USERx. Press the “MODE” button on
the front panel of the VOPEX to select the desired mode per the chart below:
INSTANT AUTO: Any user can gain immediate access to the CPU by pressing a key or moving a mouse, unless another user is
active.
DELAYED AUTO: Any user can gain access as long as no "User x" LEDs are currently illuminated. When a keyboard or mouse is
being operated by a user, that user’s LED will illuminate. When the active user’s keyboard/mouse are idle for at least 5 seconds,
the user LED goes out and anyone can then gain access.
USERx: The VOPEX has a user mode for each port. When any user mode is selected, that "User x:" LED remains ON and all
other users are locked out until the mode is changed by pressing the MODE button.
MONITORS
All monitors connected to the VOPEX display exactly the same information. For example, if the user connected to Port 3 is
inputting data, then all users connected to the VOPEX see what that user is entering.

AUDIO SUPPORT
(Optional)
The VOPEX can be ordered with optional 3.5mm stereo audio ports (ex. VOPEX-4KVIMA-A) for connection to an audio source
(“Audio In”) and up to 4 self-powered stereo speakers (Audio 1-4).
Audio support provides the following additional features:
•Audio signals from the same CPU that keyboard, mouse, and video signals are from can be received by the user.
•Audio input accepts any standard line level audio (1Vrms or 2.5Vp-p).
•Audio outputs are capable of driving an 8 Ohm speaker load with 200mW of continuous RMS power.
The audio signal is split to all users just as the video signal is split.
TROUBLESHOOTING
If any problems are experienced with the VOPEX switch, follow the steps below to see if the problem(s) can be easily corrected:
1. Verify that all cables are securely connected.
2. Verify that a monitor is connected to "MONITOR 1".
3. If a user has both a keyboard and mouse, verify that they are connected to a Keyboard port and Mouse port with the same
port number.
4. If a cable is disconnected:
a) Turn OFF power to the CPU.
b) Turn OFF power to the VOPEX.
c) Connect the cable.
d) Go through the power-up sequence described on page 3.
