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.

9

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH

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 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:

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:

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.

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 powered­ON 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.

RS232 CONTROL

RS232 Connections and Configuration

Remote Connection

The RS232 Interface is designed to meet the RS232C standard and can be controlled from any terminal (CPU or other controller
with an RS232 communications port.). The pin-out for the DB-9 connector on the unit is as follows:

RS232 Connector (DB-9 FEMALE)

PIN SIGNAL FUNCTION

1 CD Carrier Detect

2 TXD Transmit data (RXD at host)

3 RXD Receive data (TXD at host)

4 DTR Data terminal ready

5 GND Signal ground

6 DSR Data set ready

7 RTS Request to send

8 CTS Clear to send

9 - No connection

Note: Security must be disabled or user access granted on the port(s) to be selected by RS-232 control.

On the DB-9 female connector, pins 1 (DCD), 4 (DTR), and 6 (DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted.
Therefore, host handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null
modem) will work for most CPUs. To daisy chain multiple units, a Matrix Y-1 cable is used (see page 24) for each NODEMUX in
the chain. The last unit will have no connection on its output port and should have DIP switch 1 ON (see table under "Unit
Address and Loop Back" on page 21).

Configuration

Baud Rate

In order for a terminal to communicate with the NODEMUX, the terminal and NODEMUX must each be configured for the same
baud rate.

Press <W> from the Administration Mode menu (page 11) to enter Switch Configuration mode. (Fig. 25)
Press <Tab> once to move the cursor bar to highlight "RS232 BAUD RATE". The default setting is 9600.
Press < > (up arrow) or < > (down arrow) to change the selected baud rate to 300,600,1200,2400,4800, or back to 9600.

Be careful with
this field. If
changed to
SLAVE, OSD will
not work after
power cycling.

Figure 21- Switch Configuration Mode screen

In the event the setting is changed
from "stand alone" to "slave", when
the switch is power cycled the OSD
menu will no longer work. To restore
the setting back to "stand alone",
factory default settings must be
restored via a terminal connected to
the RS232 control port. See the
RS232 Command "CF" on page 24 to
restore default settings.

21

NTI NODEMUX SERIES UNIVERSAL KVM SWITCH

Loop Back

In order for an RS232 command and a response to the command to be viewed at the terminal screen, the NODEMUX must have
its Loop Back feature enabled.

More than one NODEMUX may be connected to a terminal at a time. To do so, a Matrix-Y-1 cable (available from NTI) must be
used. (See Fig. 22). For each additional NODEMUX connected, another Matrix-Y-1 cable will be required.

If the NODEMUX is one of two or more switches being controlled via RS232, and if the NODEMUX is not that last switch in the
series of switches controlled, then this setting should be changed to "DISABLED".

If the NODEMUX is the only device controlled via RS232 , or if it is the last
this setting should remain "Enabled". (See Figure 21)

To enable or disable loop back, from the

Command Protocol

CPU controller commands supported by the unit are defined below. All commands should be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit . All characters
in the command string should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01). As command
strings are sent, the inner character delay cannot exceed 500 milliseconds.

Note: To use this command protocol, the user is required to write a program that will send an entire command string all
at once, not character by character. Programs that send one character at a time (such as HyperTerminal) cannot be used
to control the NODEMUX. Alternatively, the user may use the NTI Switch Control Program or SerTest to control the
NODEMUX via RS232 (see page 25).

Terminal control commands supported by the NODEMUX are defined below.

RS - reset unit(s) to default power-up switch connections
FORMAT: RS AA<CR>
RS = "reset unit" command followed by at least one space
AA = unit address; if 00, all units on the bus will be reset and no response will be
returned
RESPONSE: *<CR> if command received and executed OK

-OR-

?<CR> if syntax or transmission error occurred

Note: The RS command does not change the switch configuration, it changes CPU-to-user connection settings.

CS - change single USER channel

FORMAT: CS AA,XX,YY<CR>

CS = "change single output" command followed by at least one space

AA = unit address

XX = input/CPU to connect

YY = output/USER to change

KEYBOARD-TO-CPU TRANSLATION

The NTI NODEMUX enables the mixture of otherwise incompatible devices and CPUs to control each other. It accomplishes this
by performing keyboard-to-CPU translations automatically (i.e. connect a SUN keyboard and mouse to a PS/2 type CPU). The
chart below shows the key commands that will be recognized and translated for the different types of CPUs. Following the chart
below, find the character desired to type or function to be performed, then follow the row across for the key or series of keys to
press on the keyboard currently in use.

Keyboard Replacement

If the keyboard is being replaced with one from the SAME PLATFORM, it can be hot-swapped without powering-down.

To change the keyboard configuration from one platform to another, simply unplug the old keyboard, plug in the new keyboard,
and power cycle the NODEMUX once.

NON-OSD TOUCH SCREEN SUPPORT

(Optional-4 and 8 port models only)

NON-OSD touch screen support allows a single touch-screen monitor, and SUN or PS/2 mouse and keyboard to
communicate directly with any PS/2 workstations connected to the switch.
The NTI ST-xU-TS includes serial cable connection ports in addition to the video and keyboard/mouse ports. The Serial ports
may be used for the data communications (DATA I/O) from a VGA multi-scan monitor with touch-screen features if the monitor
has touch-screen features. The keyboard/mouse ports may alternatively be used for the data communications (DATA I/O) if a
keyboard and mouse are present. At least one set of DATA I/O ports must be used, either the Serial ports, the Keyboard/mouse
ports, or both. If a VGA multi-scan monitor with touch-screen features is used, then a keyboard and mouse are not necessary.
If a keyboard and mouse are going to be used, then a standard VGA multi-scan monitor without touch-screen features can be
used. It is also possible to use both the monitor with touch-screen features and a keyboard with mouse.

AUDIO SUPPORT

(Optional)

Audio support provides the following additional features:

• Audio signals from the same CPU that keyboard, mouse, and video signals are from can be received by the user.

• Audio inputs accept any standard line level audio (4Vp-p).

• Audio outputs are capable of driving self-powered speakers or headphones.

Audio signals are switched along with the keyboard, mouse and video signals using the buttons on the UNIMUX switch.

TROUBLESHOOTING

PROBLEM:
SOLUTION:

PROBLEM:
SOLUTION:

PROBLEM:
SOLUTION:

PROBLEM: Monitor shuts down while working with OSD menu

GENERAL NOTE: Verify that the port 1 LED (on the front panel of the KVM switch) illuminates when the power switch is
turned ON. If it doesn’t, call NTI for assistance.

Turn ON power to the NODEMUX first, then to the CPUs.

Always turn power ON in this sequence.

Keyboard Errors
Check cable connections on each CPU and the switch.
NOTE: If the cable from a CPU’s keyboard port is disconnected from the NTI Universal KVM switch while
power is ON, turn the power OFF to the CPU before plugging the cable back in.

No Video

• Check cable connections on each CPU and the switch.

• Verify that the keyboard and video cables are connected from each CPU to matching ports. After

reconnecting, the CPU may need to be re-booted in order to sense that the monitor is connected.

No Mouse Movement

• Check cable connections of mouse to keyboard

• Verify that mouse driver was loaded. (If you are unsure how to do this, contact your system

administrator.)

• Verify the Broadcast Mode is not enabled (OFF)

• Disengage or increase time setting of CPU monitor’s “sleep” mode from the BIOS and/or control panel

display settings. The CPU does not sense activity while in the OSD menu.
