NTI BRANDNAME AND DESCRIPTON
INTRODUCTION
The VOPEX-USBV-2-HUB (VOPEX) is a USB KVM Splitter and 3-Port Hub. It enables the control of one USB enabled CPU
through two separate USB keyboards, USB mice, and VGA monitors and it enables the connection of 3 additional USB devices
(other than keyboards or mice). Each user is able to have complete control of a CPU, provided they don't try to access it at the
same time. While the user access is controlled by four (4) separate modes of operation, both user monitors will show the same
image at all times. The 3 hub ports (for printer, scanner, camera, etc.) will be connected to the CPU at all times.

NTI BRANDNAME AND DESCRIPTON
Mice and Trackballs with MACs
The VOPEX can be configured to enable full functionality between mice and trackballs having two or more buttons and a USB
MAC CPU. By default, the CPU port on the VOPEX is configured for use a WINDOWS or SUN CPU and has no special
translation for using multi-function mice and trackballs when a MAC CPU is connected. Using the commands in Command Mode
above, either enable or disable this feature as needed.
NOTE: Be sure to re-configure port for connection to a WINDOWS or SUN CPU if a MAC CPU is removed and a
WINDOWS or SUN CPU is then connected.
International SUN Keyboards
The VOPEX can recognize international layouts for Sun keyboards. In order to use an international Sun keyboard, follow this
procedure:
1. Disconnect the CPU from the VOPEX
2. Connect the international keyboard to be used to the VOPEX
3. Power down the VOPEX for at least 3 seconds
4. Power up the VOPEX
5. Reconnect the CPU to the VOPEX
It is also possible to configure the VOPEX to emulate a specific international Sun keyboard regardless of what actual keyboard is
connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an
explicit layout code (i.e. some Windows keyboards). To do this, manually set the VOPEX to indicate the international keyboard
identification number to the CPU using the following procedure;
1. Connect the keyboard to be used to the VOPEX
2. Power down the VOPEX for at least 3 seconds
3. Power up the VOPEX
4. Enter Command Mode (<Ctrl> - <`>)
5. Type Lxx, where xx is the number from the list below that corresponds to the desired country code
6. Exit Command Mode
7. Power down the VOPEX for at least 3 seconds
8. Power up the VOPEX
9. Reboot the CPU connected to the VOPEX
