INTRODUCTION
The NTI ST-nXm-U-HD (also known as NODEMUX-HD) is a multi-user / Universal Multi-Platform Matrix KVM switch, (n= number
of users, m= number of CPUs) with high density construction to require less rack space. It allows multiple users, up to 4, each
with a keyboard, monitor, and mouse, to communicate directly with any PS/2 or SUN workstation connected to the switch. A
single switch can connect to up to 16 CPUs. These CPUs can be file servers, network managers, etc. The auto-boot circuitry in
the NTI switch allows all CPUs to boot simultaneously without keyboard and/or mouse error. Resolution is supported through
1900x1200 with no degradation – guaranteed.

5. For each CPU: Connect a VMTINT-xx-MM (PS/2 CPU) or SMTINT-xx-MM (SUN CPU) or MMTINT-xx-MM (MAC CPU) cable
to the devices port(s) and video port of the CPU as shown in Fig. 2.
NOTES:
If the CPU is a SUN type with 13W3 video connector, use an NTI 13W3M-15HDF adapter to connect the SMTINT-xx-
MM cable to the CPU.
If the CPU only has a serial port for mouse connection (via a com port), a VOPEX-IM9D must be used to convert the
signal from the serial port to PS/2 port. Do not use a 9D-to-6mD adapter, it will not work.
For USB SUN CPUs, a USB-SUN adapter and a USB-AB-Xm cable must be used to connect the SMTINT-xx-MM cable
to the CPU. See Fig. 2.
6. Connect the high density end of each cable to a CPU x port on the ST-nXm-U-HD switch. See Fig. 2.

7. Plug the NTI Switch into an AC power outlet.
8. Turn ON power to the NTI Switch, the LCD should illuminate.
9. Turn ON power to any or all CPUs connected to the NTI Switch.
NOTE: The order in which the CPUs and switch are turned ON does not matter. A power strip can be used.
USING THE NODEMUX-HD SWITCH
Basic Operation
This unit enables any user to access any CPU at any time with no restrictions or limitations. Users can even share a CPU and
work on the same project – each from their own console. A Liquid Crystal Display (LCD) on the front panel indicates the port to
which the user is attached. The ST-nXm-U-HD can be controlled by three methods;
front panel keypad control with LCD
keyboard control with on-screen display (OSD)
RS-232 interface.
Keypad Control
The front panel keypad and LCD display allow the user to monitor switch status and route any user to any CPU on the switch.
Along with the routing of the inputs to the outputs 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. (See page 8.)
Display previous 4 users and the CPUs they are connected to. (See page 8.)
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

The following examples show various methods of routing user 3 to CPU 5. Users and CPUs 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
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.

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 Feature
The security feature in the OSD control of the ST-nXm-U-HD 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-
U-HD 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-U-HD switch
using the keyboard and mouse.
Administrator Login
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. 3).
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 3- User login screen
Once logged-in, follow the instructions on pages 11 and 12 for setting up users and changing the administrator 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.

NTI NODEMUX HD Multi-user Universal KVM Switch
10
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 on page 8 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.
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 (case sensitive) 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. A port is skipped
from the scan cycle if one of the following conditions is true:
- the port is used by another user
- security mode is enabled and the user does not have access rights to the port
- the CPU connected to the port is OFF
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 Command Mode above 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.
