Power-Up Sequence
•The UNIMUX 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.
•USB input devices (keyboard and mouse) can be hot plugged to and from the UNIMUX at any time.
Immediately after powering ON the UNIMUX, the following splash screen will appear on the monitor (except on 2-port model):
If the security option is enabled (see page 12 for details on the
"Security Option"), when the UNIMUX is powered up the user will
be prompted for a username and password to continue. If the
security option is not enabled the monitor will display the desktop
image for the connected CPU and the user can continue with
normal operation of the connected CPU.
Limitations
•Only USB input device or hub cables can be connected to the UNIMUX at the USB Type A female ports labeled "DEVICES".
(See Features and Functions on page 3, item 11.)
•A USB hub (single or multi-port) can be used provided only USB input devices are plugged into it.
•Only a USB Windows or SUN keyboard or USB mouse may be connected to the USB port on a USB MAC keyboard
•A maximum of 8 input devices may be connected to the UNIMUX either directly or through hubs.

USING THE UNIMUX USB KVM SWITCH
Once the UNIMUX is properly connected, the UNIMUX will enable a connection to be made between the CPUs attached to its
VIDEO and CPU ports and the monitor and input devices attached to the MONITOR and DEVICES ports. The LEDs on the
control panel of the UNIMUX will illuminate depending on which port (and corresponding CPU) is being connected to the monitor
and input devices.
The UNIMUX can be controlled by three methods:
•front control panel using touch-switches and LEDs
•keyboard control through Command Mode
•mouse clicks from within some menus of OSD Command Mode
Front Panel Control
There is a touch-switch and LED on the front panel of the UNIMUX for each CPU the switch will connect the monitor and
input devices to. Pressing any touch-switch on the front panel of the UNIMUX will connect the corresponding CPU to the monitor
and input devices.
Holding down any front panel touch-switch for more than 2 seconds will cause the UNIMUX to cycle through all modes of
operation including COMMAND, BROADCAST, SCAN, and NORMAL (described in "Basic Command Mode" on page 9 and in
"User Access Functions" starting on page 18). The three MODE LEDs on the front panel indicate which mode is selected.
Release the touch-switch when the LEDs indicate the desired mode. When no mode LEDs are illuminated the user is in Normal
Mode controlling directly the CPU to which the user is connected through the UNIMUX.
Keyboard Control
Keyboard control of the UNIMUX can be achieved using either of two methods:
•Basic Command Mode- operated strictly by using keyboard commands as instructed below. Basic Command Mode
is only applicable in UNIMUX-USBV-2.
•OSD Command Mode- operated using the keyboard and mouse in conjunction with OSD menus superimposed
onto the monitor. For all models other than UNIMUX-USBV-2, use the menus as instructed on page 12.
By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode (either Basic, or OSD). Once in Command
Mode, typing a series of commands will cause the UNIMUX to connect the user to any one CPU connected to the switch.
Pressing the <Esc> key will exit Command Mode.

MODES OF OPERATION
Basic Command Mode
In order to control the UNIMUX with the keyboard connected, Command Mode must be enabled. To enter Command Mode from
the keyboard:
Press
NOTE: Basic Command mode is only used in a UNIMUX-USBV-2. All other UNIMUX-
USBV-x switches have OSD installed. To control these models, proceed to “OSD
CONTROL” on page 12. If this is a UNIMUX-USBV-2, continue on this page.
When the COMMAND LED is illuminated, all 3 status lights on the keyboard will illuminate (if they aren't already due to caps lock,
scroll lock, and/or num lock) to indicate that Command Mode is enabled and the following functions are available:

To activate or deactivate Scan Mode press <S> while in Command Mode. When in Scan Mode the switch scans to each port
with a CPU powered-ON. (The SCAN LED on the front panel will illuminate and remain ON while in Scan Mode. ) The port with
the CPU powered-ON remains active while in use until it becomes idle for the configured dwell time (default time-out period is 5
seconds) before switching to the next powered-ON CPU port. See Command Mode section above for configuring the scan dwell
time.
Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active
port.

Broadcast Mode
To activate or deactivate Broadcast Mode press <B> while in Command Mode. Broadcast Mode enables the user to type
characters to both computers simultaneously.
NOTE: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the
<Backspace> key.
Normal Mode
When all of the UNIMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected
through the UNIMUX.
No SUN Sleep Mode
PLEASE NOTE: It is necessary to configure a SUN CPU (most versions) such that the Sleep Mode is not enabled. If the
SUN CPU goes into Sleep Mode either automatically or manually, the user must reboot the SUN CPU in order to resume
use of the SUN CPU.
To disable the Sleep Mode, perform the following steps:
1. Select "Power Manager"
2. Look for "Device Idle Time Before Power Saving Starts"
3. Select "Always ON"
4. Look for "Override Device Idle Time For:"
5. Make sure neither "Monitors" nor "Disks" are selected.
Select Country Code
It is possible to configure the UNIMUX 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 to indicate the international keyboard
identification number to the CPU using the following procedure;
1. Connect the keyboard to be used to the UNIMUX
2. Enter Command Mode
3. Type Lxx, where xx is the number from the list below that corresponds to the desired country code
4. Exit Command Mode
5. Reboot the CPU connected to the UNIMUX

Mice and Trackballs with MACs
The UNIMUX 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 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 <M> + <x> + <x>
(xx = port number), or <W> + <x> + <x> in Command Mode (page 8), either enable or disable this feature as needed for each
port.
NOTE: Be sure to reconfigure port for connection to a WINDOWS or SUN CPU if a MAC CPU is removed and a
WINDOWS or SUN CPU is then connected.

OSD CONTROL
OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named
(with up to 12-character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or
by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will locate
it. Help screens assist with all OSD functions.
Security Option
The security option of the OSD Control enables an administrator to control access to CPU ports for each user. Up to 63 users
can be created. These users have controlled access to any CPU. Only the administrator can activate or deactivate the security
features. Security can be activated from the Maintenance Mode menu (page 24) with a successful administrator login for
verification purposes. Furthermore, the administrator can set a maximum idle time value after which the current user will be
logged out and the login screen displayed. This time out does not function while the OSD is active. The current security status,
idle time out, and scan dwell time are all saved and will be restored whenever power to the switch is cycled OFF, then ON. To
reset the administrator's password call NTI and have the device serial number of the UNIMUX available.
Enabling the Security Feature
To enable the security feature the administrator must first enter Command Mode from the keyboard using the sequence
<Ctrl> + <`> (accent key). The OSD menu will automatically appear on the monitor in addition to illuminating the Command Mode
indicator LED on the UNIMUX. This provides a visual way to control the UNIMUX using the keyboard and mouse.
The administrator , when setting the USB KVM switch up for the first time, may want to proceed directly to the
ADMINISTRATION Mode by typing <Ctrl> +<M> , then <A>, and then <Y>.
The factory settings are:
•default user name = ADMINISTRATOR
•default password = ADMINISTRATOR
Note: The user name for the administrator cannot be
changed from "ADMINISTRATOR".
FYI: Capital letters are introduced by keeping the <Shift>
key pressed while typing. The <Capslock> does not work
while in OSD.
Once logged-in, follow the instructions on page 15 for setting up
users and changing the password. Once the password is setup, if
it is lost or forgotten the administrator will have to contact NTI for
assistance on clearing the password and set it up again. Within
the Administration Mode the administrator can setup each of the
users and the limitations of their use of the individual CPUs
attached to the switch.
Figure 9- Administrator Login screen
When a standard user powers up the system a security screen will appear if security has been enabled by the
administrator. The user will need to login to the switch by following the instructions on page 13 for the USER LOGIN. If the
user does not know the appropriate user name and password (setup by the administrator), contact the switch administrator for this
information. Once logged-in a user can follow the Command Mode functions described on page 16 to control the switch within
the limitations as determined by the administrator.

switch .
Note: The Alternate Command Hot Key does not replace the
<`> (accent) key, it just works as another way to enter into
Command Mode. After setting it, the user can enter into
Command Mode either with <Ctrl> + <`> or with <Ctrl> +
<Alternative Command Hot Key> combination. To disable it,
the administrator should set <`> as the Alternate Command
Hot Key.
