POWER-UP SEQUENCE
The UNIMUX-USBV-2 USB KVM switch can be powered at any time. The CPUs can be powered at any time although if a CPU
needs a keyboard and/or mouse at power-ON it should be powered after connecting to and powering-ON the UNIMUX-USBV-2
USB KVM switch. USB devices (keyboard and mouse) can be hot plugged to and from the UNIMUX-USBV-2 USB KVM switch at
any time. Remember, the last attached device is the active one.
USING THE NTI SWITCH
USING THE NTI SWITCH
The NTI UNIMUX-USBV-2 USB KVM switch can be operated by the CPU SELECT button on the side of the switch or by
keyboard control.
CPU Select
•Pressing the CPU SELECT button on the UNIMUX-USBV-2 USB KVM switch will toggle between CPU 1 and CPU 2 which
connects the selected CPU to the user's keyboard, monitor, and mouse.
•Holding down the CPU SELECT button for more than 2 seconds will cause the UNIMUX-USBV-2 USB KVM switch to cycle
through all modes of operation: COMMAND, SCAN, BROADCAST, and NORMAL (see pages 6 and 7 for Command, Scan,
Broadcast, and Normal mode sections). After the first change, modes will continue to change every 2 seconds as long as
the CPU SELECT button is still pressed in. The CPUx LEDs will indicate which mode the switch is in (see the table below).
Release the button when the desired mode has been selected.

Scan Mode
Scan Mode is indicated by a flashing CPU port LED. In Scan Mode the switch scans back and forth between po rts
making the CPU connected to the port with the flashing LED active. That connected port will remain active while in
use. When the connected port becomes idle for the user selected time out period (default time is 5 seconds), the
UNIMUX-USBV-2 USB KVM switch will connect to the other CPU port. See Command Mode section on page 5 for
configuring the scan time out period.

NOTE: The keyboard and mouse must remain idle for the full scan time out period before the UNIMUX-USBV-2 USB KVM
switch will connect to the other port.
Broadcast Mode
(use with extreme caution)
Broadcast Mode allows the user to send keystrokes to all active CPUs. Broadcast Mode is indicated by illuminating the
CPU x LEDs in rapid alternating intervals . Broadcast Mode has some critical requirements:
a. Broadcast Mode must be OFF when booting any attached CPUs.
b. Broadcast Mode must be ON and the user must exit Command Mode for keystrokes to reach attached CPUs.
NOTE: The mouse is disabled leaving only the keyboard active during Broad cast Mode.
Normal Mode
The UNIMUX-USBV-2 USB KVM switch is in Normal Mode when only the LED for the active CPU is illuminated solid (not flashing
as in Scan Mode). When in Normal Mode, the user is controlling only the CPU to which the user is connected through the
UNIMUX-USBV-2 USB KVM switch. In Normal Mode the UNIMUX-USBV-2 USB KVM switch will only switch between CPUs 1
and 2 when the user uses either keyboard control or button control to do so.
Mice and Trackballs with MACs
The UNIMUX-USBV-2 USB KVM switch can be configured to enable full functionality between mice and trackballs having two or
more buttons and USB MAC CPUs. By default, the ports on the UNIMUX-USBV-2 USB KVM switch are configured for use with
WINDOWS and SUN CPUs and have no special translation for using multi-function mice and trackballs when a MAC CPU is
connected. Using the commands in Command Mode on page 6, either enable or disable this feature as needed for each port.
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.

KEYBOARD FEATURES
KEYBOARD FEATURES
The keyboard configuration of each CPU is saved in the NTI UNIMUX-USBV-2 USB KVM switch. For example, if the CPU
attached to Port 2 had CAPS LOCK and NUM LOCK selected the last time that CPU was accessed, then they will automatically
be set when that CPU is accessed again.
Keyboard-To-Computer Translation
The NTI UNIMUX-USBV-2 USB KVM switch enables a mixture of otherwise incompatible peripheral computer components to be
connected together. This is accomplished by performing keyboard-to-computer translations automatically (i.e. translate a MAC
keyboard and mouse to a Windows type CPU). The chart below shows the capabilities of devices controlling certain CPU types.

International Sun Keyboards
The UNIMUX-USBV-2 USB KVM switch can recognize international layouts for Sun keyboards. In order to use
an international Sun keyboard, follow this procedure:
1. Disconnect the CPU from the UNIMUX-USBV-2 USB KVM switch
2. Connect the international keyboard to be used to the UNIMUX-USBV-2 USB KVM switch
3. Disconnect power to the UNIMUX-USBV-2 USB KVM switch for at least 3 seconds

9
It is also possible to configure the UNIMUX-USBV-2 USB KVM switch 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 UNIMUX-USBV-2 USB KVM switch to indicate the international keyboard identification
number to the CPU using the following procedure;
1. Connect the keyboard to be used to the UNIMUX-USBV-2 USB KVM switch
2. Disconnect power from the UNIMUX-USBV-2 USB KVM switch for at least 3 seconds
3. Reconnect power to the UNIMUX-USBV-2 USB KVM switch
4. Enter Command Mode
5. Type Lxx, where xx is the number from the list below that corresponds to the desired country code
6. Exit Command Mode
7. Disconnect power from the UNIMUX-USBV-2 USB KVM switch for at least 3 seconds
8. Reconnect power to the UNIMUX-USBV-2 USB KVM switch
9. Reboot the CPU connected to the UNIMUX-USBV-2 USB KVM switch.
