Power-Up Sequence
The UNIMUX-USBV-4 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-4
USB KVM switch. USB devices (keyboard and mouse) can be hot plugged to and from the UNIMUX-USBV-4 USB KVM switch at
any time.
Note: If the DDC support option is installed, the UNIMUX-USBV-4 and the monitor must be powered up before any CPUs
are powered up.
Immediately after powering ON the UNIMUX-USBV-4 USB KVM switch, the following splash screen will appear on the monitor if
the OSD option is built into the switch:
If the security option is enabled (see page 8 for details on the "Security Option"), when the user presses any key the user will be
prompted for a username and password to continue. If the security option is not enabled, when the user presses any key the
splash screen will disappear, the monitor will display the desktop image for the connected CPU, and the user can resume normal
operation of the connected CPU.
USING THE NTI SWITCH
USING THE NTI SWITCH
Front Panel Control
There is a touch-switch and LED on the front panel of the UNIMUX-USBV-4 USB KVM switch for each CPU the switch will
connect the monitor and input devices to. Pressing any touch-switch on the front panel of the KEEMUX-USBV-xU USB KVM
switch 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-USBV-4 USB KVM switch to
cycle through all modes of operation including COMMAND, BROADCAST, SCAN, and NORMAL (described on pages 5-7). The
two 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-USBV-4 USB KVM switch.
Keyboard Control
Keyboard control of the UNIMUX-USBV-4 USB KVM switch can be achieved through either
• Basic Command Mode- Basic Command Mode is operated strictly by using keyboard commands as instructed below. Basic
Command Mode is only applicable if the OSD option is not built into the switch.
-OR-
• OSD Command Mode (optional- only available on 4 port switch )- OSD Command Mode is operated using the input devices in
conjunction with OSD menus superimposed onto the monitor. If OSD is built in, use the menus as instructed on page 8.
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-USBV-4 USB KVM switch to connect the user to any one CPU connected to the
switch. Pressing the <Esc> key will exit Command Mode.

Broadcast Mode
Broadcast Mode enables the user to type characters to all CPUs simultaneously. A port doesn’t receive broadcast data if
Security Mode is enabled and the user does not have access rights to the port.
NOTE: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the
<Backspace> key.
Scan 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.
Normal Mode
When all of the UNIMUX-USBV-4 USB KVM switch mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which
the user is connected through the UNIMUX-USBV-4 USB KVM switch.
Select Country Code
It is possible to configure the UNIMUX-USBV-4 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-4
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-4 USB KVM switch
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-USBV-4 USB KVM switch.

No Sun Sleep Mode
PLEASE NOTE: It may be necessary to configure a Sun CPU (most versions) such that the Sleep Mod e is not en abled. 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.
Mice and Trackballs with MACs
The UNIMUX-USBV-4 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-4 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 <M> + <x> (x = port number), or <W> + <x> in Command Mode (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.
OPTIONAL OSD CONTROL
OPTIONAL 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.
Note: The optional OSD control feature is only available on the 4 port switch.
Security Option
The security option in the OSD Control of the UNIMUX-USBV-4O USB KVM switch 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 on each user port. Finally, the administrator can set a maximum idle
time value after which the current user will be logged out and the login screen displayed again. 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. In the event the administrator password is lost or forgotten, to reset the
administrator’s password call NTI and have the device serial number of the UNIMUX-USBV-4O USB KVM switch available.
Enabling The Security Feature
To enable the security feature the administrator must first enter Command Mode from the keyboard using the <Ctrl> + <`> (accent
key). The OSD menu will automatically appear on the monitor. This provides a visual way to control the UNIMUX-USBV-4O
USB KVM switch using the keyboard and mouse.
The administrator will activate security when logging in by typing <Ctrl> +
<M> , then <A>, and then <Y>. The administrator will then be prompted
for a valid administrator username and password (see Fig. 4).
The factory administrator login settings are:
• default user name = ADMINISTRATOR
• default password = ADMINISTRATOR
Note: The username for the administrator cannot be changed
from "ADMINISTRATOR".
Figure 4- User Login screen
8
Once logged-in, follow the instructions on page 10 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. The
administrator can setup each of the users and the limitations of their use of the individual CPUs within the Administration Mode.
When a standard user powers up the system a security screen may appear as setup by the administrator. The user will
need to login to the system by following the instructions below for the USER LOGIN. If the user does not know the appropriate
user name and password (setup by the administrator), contact the system administrator for this information. Once logged-in a
user can follow the Command Mode functions described on page 12 to control the system of CPUs within the limitations as
determined by the administrator.
User Login Mode
User Login Mode requires a user to login with a user name and password from the list created by the administrator. With security
enabled, the user will be locked to the current CPU and the login screen will remain on the monitor until the user logs in.
Function: Keystroke:
Add a character to the
user name/password
Remove previous character
from the user name/password
Submit user name/password
Exit USER LOGIN and return
to previous mode. This function
is only available if security is
not currently enabled.

Scan Mode
To activate Scan Mode press <Ctrl> + <S> from the Command Mode menu.
Scan Mode enables the user to scan through selected ports and to have full device control of the connected port. From the
Change Settings menu (see page 15) the user can edit the list of ports that can be scanned. A port is skipped from the scan cycle
if one of the following conditions is true:
- the port is not in the scan list
- security mode is enabled and the user does not have access rights to the port
- the CPU connected to the port is OFF
When switching to a new port the port name is displayed by OSD in the left upper corner of the monitor for 5 seconds or until a
key is pressed or the mouse is moved, whichever comes first. The scan dwell time is programmable from 2 to 255 seconds
(default time-out period is 5 seconds). When the user uses the mouse or keyboard the scanned port becomes active and scannin g
is stopped. The switch will resume scanning after a period of user inactivity determined b y the scan dwell time. See Change
Settings Menu on page 15 for configuring the scan dwell time.
NOTE: The scan dwell time set by the user only effects that user and has no effect on oth er switch users.
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 Broadcast Mode press <Ctrl> + <B> from the Command Mode menu.
Broadcast Mode enables the user to type characters to more computers simultaneously. From the Change Settings menu (see
page 15) the user can edit the list of ports that receive data in Broadcast Mode. A port doesn’t receive broadcast data if one of the
following conditions is true:
- the port is not in the Broadcast Mode l ist
- Security Mode is enabled and the user does not have access rights to the port
NOTE: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the
<Backspace> key.
Normal Mode

MAC Ports Configuration
NOTE: The CONFIGURE MAC PORTS option will be in blue text in the Change Settings menu and will only be accessible
if the administrator is logged in.
MAC Ports Configuration menu enables the administrator to select specific ports to be connected to MAC CPUs for passing
mouse information to the MAC CPUs. This is useful when the user wants to use mouse drivers provided by the mouse vendor,
which allows the use of programmable functions for each button. Ports should be configured at installation time or whenever
necessary. After setting, the configuration is stored in non-volatile memory and will be retrieved whenever the switch is power
ON. When the port is connected to a Windows or SUN CPU, this configuration SHOULD BE DISABLED. By default, all ports are
configured as non-MAC CPUs (Windows and SUN).
NOTE: If a port is configured as connected to a non-MAC CPU, but is in fact connected to a MAC CPU, the mouse will
still work as a generic mouse. No special functions provided by software drivers will be available.
To enter the MAC Ports Configuration menu, the administrator must press <M> from the Change Settings menu, described on
page 15.
A check list with all the ports numbers preceded by a check-box will be displayed in the window.
• unchecked box = the corresponding port is set as connected to a non-MAC CPU
• checked box = the corresponding port is set as connected to a MAC CPU
In order to change the status of a port, the administrator has to first select the port. The selected port is highlighted with a green
bar.
To select another port, the administrator can use the arrow keys or mouse movement. The name of the selected port is displayed
at the bottom left of the menu, right above the yellow bar.
The administrator can toggle the state of the selected check box by pressing the <Spacebar> or clicking the left mouse button.

useful when cascading switches (for Cascading see page 22). An example of this structure might be
LEVEL 1 : PORT 5
LEVEL 2 : PORT 3
This means that the CPU connected through this port is actually connect through Port 5 of the master switch (Level 1), and
through port 3 of the slave connected to port 4 (Level 2). See Fig. 14 below.

KEYBOARD FEATURES
KEYBOARD FEATURES
The keyboard configuration of each CPU is saved in the NTI UNIMUX-USBV-4 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-4 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.

Figure 15- Keyboard Layouts
International Sun Keyboards
The UNIMUX-USBV-4 USB KVM switch can recognize international layouts for Sun keyboards. In order to use an international
Sun keyboard, follow this procedure:
1. Power-OFF the CPU from the UNIMUX-USBV-4 USB KVM switch
2. Connect the international keyboard to be used to the UNIMUX-USBV-4 USB KVM switch
3. Power-ON the CPU to the UNIMUX-USBV-4 USB KVM switch
It is also possible to configure the UNIMUX-USBV-4 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-4
USB KVM switch to indicate the international keyboard identification number to the CPU by following the instruction on p age 7 (for
switches without OSD feature) or on page 16 (for switches with OSD feature).
21
CASCADING
CASCADING
The UNIMUX-USBV-4O USB KVM switch can be expanded to access up to 128 CPUs by cascading multiple units together. As
many switches as there are CPU ports may be connected to a UNIMUX-USBV-4O USB KVM switch. Single user and multi-user
UNIMUX switches may be connected downstream (see Figs.16 and 17). The first s witch in a cascaded system is referred to as
the "master", while all downstream switches are referred to as "slaves". The only additional hardware required to cascade
switches is a set of device and monitor cables for each “SLAVE UNIT” (see MATERIALS on page 1). All CPUs and switches can
then be controlled by users using OSD commands with Command Mode.
Note: The UNIMUX 4 port USB KVM switch must have OSD installed to use cascading.
Note: Cascading is not an option in the UNIMUX-USBV-2 2 port USB KVM switch.

Limitations
The front panel buttons are only used to operate standalone switches. To control a cascaded network of switches, only the OSD
commands within Command Mode will be recognized.
Users connected to accessible ports on downstream slaves (i.e. ports not connected to the master, as in the case of multi-user
slaves) will not be able to control switches or CPUs connected upstream. Only control over CPUs and slaves downstream from
a user's connection point will be enabled. (See Fig. 17)

Cable Connections
The same cable used to connect a CPU to the UNIMUX is used to connect two UNIMUX switches together- USBVEXT-xx-MM.
No other cables will be necessary. To connect a slave to a master
1. Connect the USB-A-male end of the USBVEXT-xx-MM to the USER 1 port on the slave.
2. Connect the 15HD male at the same end of the USBVEXT-xx-MM cable to the MONITOR 1 port on the slave.
3. Connect the USB-B-male end of the USBVEXT-xx-MM to the CPU 1 port on the master.
4. Connect the 15HD male at the same end of the USBVEXT-xx-MM to the VIDEO 1 port on the master.
Repeat this procedure for each USER and MONITOR port on the slave that is desired to be controlled through the master. Any
USER and MONITOR ports that do not get connected to the master can be connected to by users. Users connected to a slave
downstream from the master will control only the CPUs directly connected to that slave switch (i.e. users 5 and 6 in fig. 17 above
can only control CPUs 25-40).

All the downstream switches should be powered ON before pressing any keyboard ke y. If there are USB extenders connected,
they should also be powered ON. An extra time of about 5 seconds after powering-ON the last unit may be needed to complete
the USB enumeration process. If the switch is a standalone unit (no downstream s witches connected), the keyboard ke y could be
pressed immediately.
When a keyboard key is pressed, the master switch will start the process of detecting the configuration. This could take severa l
seconds, depending on how many switches are connected together. When configuration update is ready, the splash screen
disappears and the system is ready to operate. (If security mode is activated, the login window will be disp layed on the screen).
The update-configuration function can be recalled at any time by entering into Command Mode and pressing th e <Ctrlt> + <Tab>
keys
Note: The front panel buttons are used to operate only standalone switch es. To operate a cascaded network of switches
use only OSD commands from Command Mode (see page 12).
After completing the configuration detection, the splash screen is turned OFF and the switches can be operated. All configuration
can be controlled from the keyboard, mouse and monitor through OSD menus (page 8).
DDC SUPPORT (OPTIONAL)
DDC Support (Optional)
DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up,
information from the monitor concerning its resolution specifications.
When DDC Support is installed, the DDC information is acquired from the monitor by the UNIMUX switch when the UNIMUX is
powered-up
made available at every CPU port.
. A monitor with DDC support must be connected to MONITOR for this to occur. The DDC information will be
Option not available on 2 port switches.
The DDC information can also be acquired by pressing the DDC button located on the front of the switch (see page
2, item 10). This button allows the monitor configuration to be changed without powering down the switch.
Note: In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch
must be powered up before all attached CPUs.
