INTRODUCTION
The KEEMUX-USBV-2U USB KVM switch allows one user to access two USB CPUs with only one USB keyboard, USB mouse,
and 15HD VGA monitor. Internal microprocessors allow both CPUs to boot simultaneously and error-free. Port selection is
accomplished by a front panel push button or commands typed on the keyboard.
Types of User Input Devices Supported:
• USB keyboard with Windows
layout
• USB keyboard with SUN layout
• USB keyboard with MAC layout with mouse
• USB Mouse - (up to 3 buttons)
• USB IntelliMouse
(scrollwheel)
• NTI USB-Sun Adapter
• USB Hub
Types of CPUs Supported:
Any USB CPU supporting USB version 1.0 or above including:
• USB WINxx
• USB MAC
• USB SUN
Limitations
• A USB HUB can only be used provided only a USB keyboard and/or USB mouse are connected to its inputs.
NOTE: a Mac USB keyboard already has a hub incorporated and can only be connected to one of the inputs on the
switch, not to the HUB.
• The maximum number of input devices connected to a HUB is limited to one keyboard and one mouse. Composite devices
(NTI USB-Sun Adapter) should be counted as two USB devices (one keyboard and one mo use).
• The last device type (keyboard/mouse) plugged into the KEEMUX-USBV-2U-USB KVM switch will be the only active device
of that type.
Note: Removing the second keyboard (mouse) will not re-activate the first one. To make the first keyboard (mouse)
active, the first keyboard (mouse) should be re-plugged to the KEEMUX-USBV-2U USB KVM switch or HUB.

INSTALLATION
1. It is not necessary to turn OFF power to either of the CPUs that will be connected to the KEEMUX-USBV-2U USB KVM
switch before connecting or disconnecting any cables.
NOTE: If a CPU needs to identify a keyboard, it will be necessary to power ON the CPU after it is connected to the
KEEMUX-USBV-2U USB KVM switch and only after the keyboard is connected and the KEEMUX-USBV-2U USB KVM
switch is powered ON.
2. Connect a USB keyboard to a female USB type A port labeled "USB DEVICES" on the KEEMUX-USBV-2U USB KVM switch.
See Fig. 1.
3. Connect a USB mouse to the other female USB type A port labeled "USB DEVICES" on the KEEMUX-USBV-2U USB KVM
switch.
4. Connect a VGA multi-scan monitor to the female 15HD VGA port labeled "MONITOR" on the KEEMUX-USBV-2U USB KVM
switch. Be sure to tighten the two screws on the monitor cable connector to the KEEMUX-USBV-2U USB KVM switch
securely.
