NTI NODEMUX SERIES UNIVERSAL KVM SWITCH

OPERATION
Control over the CPUs attached to the NODEMUX is achieved through operation of the NODEMUX. Once the NODEMUX is
properly connected, the NODEMUX will enable a connection to be made between the CPUs attached to its "VIDEO x" and "CPU
x" ports and the keyboard, monitor, and mouse attached to the "MONITOR" and "DEVICES" ports. The LEDs on the control
panel of the NODEMUX will illuminate depending on which port (and subsequent associated CPU) is being connected to the
keyboard, monitor, and mouse. The choice of which CPU a keyboard, monitor, and mouse will be connected to is determined by
controlling the Universal KVM switch either through either of 3 methods:
•front control panel
•keyboard control through an On Screen Display (OSD) menu
•RS232 control
Front Panel Control
There is a touch-switch and LED on the front panel of the NODEMUX for each CPU the switch will connect the keyboard, monitor,
and mouse to. Pressing any touch-switch on the front panel of the NODEMUX will connect the selected CPU to the keyboard,
monitor, and mouse.
Holding down any front panel touch-switch for more than 2 seconds will cause the NODEMUX to cycle through all modes of
operation including COMMAND, SCAN, BROADCAST, and NORMAL (described on page 15). 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
NODEMUX.
Keyboard Control
A user has Keyboard control of the NODEMUX using Command Mode through on screen display (OSD) menus superimposed
onto the monitor. By pressing <Ctrl> + <`> (accent key), the user can enter Command Mode. Once in Command Mode, typing
a series of commands will cause the NODEMUX to connect the user to any one CPU connected to the switch. Pressing the
<Esc> key will exit Command Mode.
OSD
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 many OSD functions.
Security Option
The security option in the OSD menu enables an administrator to control access to the CPU ports for each user. Up to 24 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 18) 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.

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH
10
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 KVM switch. This provides a visual way to control the NODEMUX switch using the keyboard, monitor, and mouse.
The administrator , when setting the NODEMUX 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:
•user name = ADMINISTRATOR (not case sensitive)
•password = administrator (must be lowercase, do not use Shift
key)
FYI: The user name for administrator cannot be changed from "ADMINISTRATOR"
Once logged-in, follow the instructions on page 12 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 on the system.
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 Functions described on page 13 to control the system of CPUs within the limitations as set 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. Access to
the functions of the NODEMUX will not be allowed until a user has logged in.
Function: Keystroke:
Adds a character to the
user name/password

Switch Configuration
Switch Configuration enables the administrator to configure the NODEMUX to be used as a stand alone switch or as one of the
switches in a cascaded system.
Note: Cascading is no longer supported in this switch. Be careful not to change this field to anything except “STAND
ALONE SWITCH”.
Switch Configuration is also used to setup the communication settings for RS232 communication with a remotely connected
terminal through the RS232 port. For the Switch Configuration Mode menu, press <W> from the Administration Mode menu
(above).

System Access List
The System Access List displays a list of numbers representing the ports so the administrator can change access rights to the
ports for the selected user. The user’s name is displayed at the top of the access list. The mouse is used to change access rights
by clicking on a given number to toggle a port’s status. A user that has access to a port can connect to that port and control the
CPU connected to that port when in Normal Mode.
Function: Keystroke:
Save the changes to the access
list and return to previous mode
Exit the System access list without
saving and return to previous mode.
User Access Functions
Introduction
The OSD menu enables a user to name the CPUs connected to the NODEMUX and connect to them using that name from a
single keyboard and mouse. The OSD is positioned on the user's monitor, displaying 8 CPU names at a time. The screen can be
used for switching as well as editing the CPUs’ names. Through the OSD menu, the user can control the NODEMUX to cycle
through all modes of operation: COMMAND, SCAN, BROADCAST and NORMAL. Three LEDs on the front panel indicate
when these modes are enabled.
Command Mode
In order to control the NODEMUX with the keyboard connected, Command Mode must be enabled. To enter Command Mode
from the keyboard:
Press
The On Screen Display menu will automatically appear on the monitor in addition to illuminating the indicator LEDs on the KVM
switch. This provides a visual way to control the NODEMUX using the keyboard, monitor, and mouse.
With Touch Screen support (optional), the OSD menu can be entered by tapping 3 times on the monitor.
The list below describes the Command functions available from the keyboard within the OSD menu after entering into Command
Mode and while the COMMAND LED is illuminated:
Function: Keystroke:

FYI: If the Touch Screen Support option is present, the user can also exit the Main Command mode menu by tapping
once on "ESC-EXIT" on the screen, or by using a finger to align the cursor with a port number and removing the finger.
Aligning the cursor with a port and removing the finger will connect the user with the selected port in addition to exiting
Command Mode.
The mouse can also be used to control Command Mode. The mouse cursor can be moved to the Scan, Help, and Exit fields
where the user can then click on the left mouse button to perform that function. Ports listed on the screen can be selected by
moving the cursor onto that port and clicking. Clicking twice on a selected port will switch to that port and exit Command Mode.
To change the displayed ports on the screen simply click on the up and down arrows located to the right of the port names
displayed.
Note: The “port” mentioned in the command functions of Command Mode refers to the combination of the video (VIDEO
x) and device (CPU x) connections of like numbers that a CPU is connected to (i.e. the CPU that is connected to VIDEO
1 and CPU 1 will be identified as PORT 1 or P01). See Fig. 14.
Figure 14- Video and Device connections identified with port numbers
Scan Mode
When in Command Mode, press <Ctrl>-<S> to toggle Scan Mode ON/OFF. The Command Mode main menu will indicate with
“SCAN-ON” or “SCAN-OFF”.
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. Also, the Command Mode main menu will show “SCAN - ON”. ) The port with the CPU powered-
ON remains active while in use. When the switch becomes idle for the configured time-out period (default time-out period is 5
seconds) the switch will connect to the next powered-ON CPU port. See Command Mode section above for configuring the scan
time-out period.
Note: The keyboard and mouse must remain idle for the full scan time-out period before the switch will connect to the
next active port.
Broadcast Mode
(use with extreme caution or commands intended for one CPU will be sent to all CPUs)
When in Command Mode, press <Ctrl>-<B> to toggle Broadcast Mode ON/OFF. The Command Mode main menu will indicate
with “BROADCAST-ON” or “BROADCAST-OFF”.
Broadcast Mode allows the operator to send keystrokes to all active CPUs simultaneously (even those CPUs the user cannot
connect to due to lack of security access). Broadcast Mode is indicated by the illumination of the BROADCAST LED on the front
panel, and by “BROADCAST – ON” in the Command Mode main menu. The BROADCAST LED will remain ON while in
Broadcast Mode. However, Broadcast Mode has some critical requirements:
•BROADCAST LED must be OFF when booting any attached CPUs.
•BROADCAST LED must be ON and COMMAND LED must be OFF for keystrokes to reach attached CPUs.
Broadcast Mode is not supported by any ports that have MAC CPUs attached.
Normal Mode
When all of the NODEMUX mode LEDs are OFF the user is in Normal Mode, controlling the CPU to which the user is connected
through the NODEMUX.

Edit Mode
Edit Mode allows the user to modify the names of the CPUs connected to the switch. Names of CPUs can be up to 12 characters
in length. When in Edit Mode, multiple keystroke combinations are not valid (<SHIFT>+<P>, <CTRL>+<P>, <ALT>+ <P>, and <P>
will all type a “P” to the display - lower case letters cannot be typed). After changes have been made the user 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.
