USING THE NTI MULTI-USER USB KVM SWITCH
Basic Operation
The ST-nXm-USBV-U switch enables a user or several users (with sharing enabled) to access any CPU at any time. A CPU can
be shared so that more than one user can use a CPU and work on the same project – each from their own console. Resolution is
1900x1200 with no degradation – guaranteed. An LCD indicates the port to which each user is attached. The ST-nXm-USBV-U
can be controlled by three methods:
•keypad control with LCD via front panel
•OSD control via the user input devices
•RS-232 control
Keypad Control
The front panel keypad and LCD (see Fig. 6) display allow the user to monitor switch status and route any user to any CPU on the
switch. Along with the routing of the CPUs to the input devices the keypad and LCD allow the users to configure the RS-232
control interface. The keypad buttons perform the following functions:
Key Action
ESC Escape back to the main display.
0 – 9 Used to enter numbers. ( n)
USR The output user number can be entered (2 digits or 1 digit and ENTER)
followed by the desired CPU to be connected to.
CPU Used following single digit user entries.
ENTER Used following single digit entries.
Display next 4 users and the CPUs they are connected to.
Display previous 4 users and the CPUs they are connected to.
MENU The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 2400, 1200 or 300 baud and the unit
address to be set to 1 - 15. See RS-232 control on page 21.
* Activate Memory Function- 10 memory locations (0 – 9), 0 is the power ON default.
to Save current connections *- USR - n (0-9) - ENTER
to Recall connections *- CPU - n (0-9) - ENTER
Note: By default, the display will show all connections between CPUs and users, displaying 4 at a time, from the first to
the last, and repeating the cycle indefinitely. If the user presses either the up or down arrow to manually view
connections, the display will freeze on the chosen view. To resume the default cycle of displaying all connections, the
user must press and hold either the up or down arrow for 3 seconds, and then release it.
The following examples show various methods of routing user 3 to CPU 5. CPUs and users can be entered as a two digit number
or a one digit number followed by ENTER.
USR - 3 - CPU - 5 - ENTER
USR - 3 - ENTER - 5 - ENTER
USR - 0 - 3 - 0 - 5
0 - 3 - 0 - 5

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 in the OSD Control of the ST-nXm-USBV-U 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. To reset the administrator’s password call NTI and have the device serial
number of the ST-nXm-USBV-U 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 ST-nXm-USBV-U 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. 7).
The factory administrator login settings are:
•default user name = ADMINISTRATOR
•default password = ADMINISTRATOR
Note: The username for the administrator cannot be changed
from "Administrator".
Once logged-in, follow the instructions on page 11 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 13 to control the system of CPUs within the limitations as
determined by the administrator.

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 16) 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
- the port is used by another user and sharing is not enabled
- 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 scanning is
stopped. The switch will resume scanning after a period of user inactivity determined by the scan dwell time. See Change Settings
Menu on page 16 for configuring the scan dwell time.
NOTE: The scan dwell time set by the user only effects that user and has no effect on other 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 16) 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 list
- the port is used by another user and sharing is not enabled
- 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.
Sharing Mode
To activate Sharing Mode press <Ctrl> + <H> from the Command Mode menu.
Sharing Mode enables two or more users to access the same port. If Sharing Mode is disabled, the user cannot switch to a port
that is already connected to by another user.
When a port is connected to by more than one user, the user which is currently typing or moving the mouse has the access to the
port and other users cannot use it. The user will lose access after 5 seconds of no activity from the keyboard or mouse. From that
moment any other connected user can gain access.
Normal Mode
When the ST-nXm-USBV-U switch is not in Command, Scan, or Broadcast mode and the OSD control is not active on the monitor,
the user is in Normal Mode, controlling the CPU to which the user is connected through the ST-nXm-USBV-U switch.
Edit Mode
To activate Edit Mode press <Ctrl> + <E> from the Command Mode menu.
Edit Mode allows only the administrator to modify the names of the CPUs connected to the switch. Names of CPUs can be up to
12 characters in length. Characters typed can be upper or lower case. After changes have been made the administrator will be
prompted by the menu to save the changes. Answer "Y" to save changes and answer "N" to continue using previously entered
port names.

NOTE: Based on different scan rates, the OSD window may appear in different areas of the monitor as different CPU ports are
selected. The Maintenance Mode functions allow placement of the window in a particular area of the monitor and the window will
return there when the ST-nXm-USBV-U USB KVM switch is reconnected to that particular CPU (provided the parameters are
saved before exiting Maintenance Mode).
Search Mode
Search Mode is enabled by typing any alphabetical or numeric characters while in the Command Mode menu.
Search Mode allows the user to enter and maneuver through a list of CPU names. The CPU name best matching the characters
typed is selected. The list of CPUs may also be searched for a specific (or similar) name. The following commands are valid when
the search option has been invoked from Command Mode.
Function: Keystroke:
Erase previous character
in search name
Add a character to the search
string and select the best
matching CPU name

Select Language
To enter the Select Language menu (see Fig. 17) press <L> from the Change Settings menu described on page 16.
Note: Only the administrator has the Select Language menu option.
The Select Language menu enables the user to select a specific language (country code) to be used. Typically only SUN CPUs
require a specific country code to be registered at boot up. (For other types of CPUs this feature may have no effect.) A list of
available languages is displayed and can be scrolled using the mouse (scroll wheel) and/or <up arrow>, <down arrow>, <Home>
and <End> keys.
•To manually program a specific language, select a language and press <Enter> (or click the left mouse button).
•To automatically detect the language of the keyboard, select "AutoDetect" and press <Enter> (or click the left
mouse button) . The list will advance to the actual detected keyboard language and that language will be
programmed.
Some keyboards don’t have a country code. In this case the selection will remain in the “AutoDetect” position and the default
country code "00" will be programmed in the ST-nXm-USBV-U USB KVM switch. If a specific country code is manually
programmed, it will be the country code for the switch, regardless of the actual country code of the connected keyboard. The
programmed country code is saved in memory and restored each time the ST-nXm-USBV-U USB KVM switch is powered-ON.
Because the CPUs that use country code (i.e. SUN CPUs) read it at boot time, it is necessary to boot the CPU(s) after
programming the country code.
Keyboard Mapping
The keyboard configuration of each CPU is saved in the ST-nXm-USBV-U switch. For example, if the CPU attached to Port 4 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.
Key Equivalents
Using the chart below, find the character needed to be typed on the CPU being accessed, then follow the row across for the
equivalent on the keyboard being used. (See Fig. 18 on page 21 for reference.)
