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.
