NTI UNIMUX MULTI-USER KVM SWITCH
USING THE NTI UNIMUX USB KVM SWITCH
Basic Operation
The UNIMUX switch enables a user or several users 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. The front panel LCD indicates the port to which each user is attached. The UNIMUX can be
controlled by three methods:
• keypad control
with LCD via front panel
• OSD control via the user devices
• RS-232 control
(see page 29)
Keypad Control
The front panel keypad and LCD (see Figure 8) 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 user devices the keypad and LCD allow the users to configure the RS-232
control interface. The keypad buttons perform the following functions:
Action
Key
ESC Escape back to the main display.
0 – 9 Used to enter numbers. ( n )
USR The user device 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 note below.)
Display previous 4 users and the CPUs they are connected to. (See note below.)
MENU The RS-232 menu is displayed. This allows the baud rate to be set at 9600, 4800, 2400 or 1200 baud and the
unit address to be set to 1 - 15. See RS-232 control on page 29.
* 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
to set all outputs to one input * - 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.

(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.
OSD Standards of Operation
Throughout this manual, various standards of operation apply to the menus used to control and operate the UNIMUX.
• OSD menus can be navigated using the mouse, the arrows on the keyboard, hot keys (highlighted in red) and the
<Page Up>, <Page Down>, <Home>,<Tab> and <End> keys.
- The <up arrow> and <down arrow> moves the cursor up or down one line item at a time in a scrollable
window, or between menu items in a menu item list
- The <left arrow> and <right arrow> will move the cursor left or right through menu items or while in
editable fields (such as when editing port names)
- <Page Up> and <Page Down> increase/decrease the listed ports by one page at a time
- <Home> will jump to the beginning of the list
- <Tab> will jump between selectable fields, left to right
to move between menu items
- <Shift>+<Tab> will jump between selectable fields, right to left
- <End> will jump to the end of the list.
• Only alphabetic and numeric characters can be typed in the OSD menu fields
• Positioning the mouse cursor over a menu function or CPU name will highlight the background (green highlight for
menu functions, cyan or light blue for CPUs)
• The scroll bar can be used by clicking on the corresponding up and down arrow above and below the scroll bar.
• The mouse wheel may be used to move the selection bar
• The <Shift> key must be used to enter an uppercase letter within all OSD menus.
• Clicking on a listed CPU while in Command Mode will connect the user that CPU.
• Available functions will have white characters with one red character. The red character corresponds to a keyboard
“hot key”. Hot keys are not case sensitive. Functions that are not available will be transparent.
• When changing characters for names, passwords, or values within an edit field, click on the field or select and press
<Enter> to enter the field for editing, and press <Enter> again to exit the edit field.
• To exit (and step back 1 menu) from any menu, press <Esc> on the keyboard .
• All screens that include “F1:Help” for context-sensitive help will also respond to pressing the <
“Global Help” screens with basic menu navigation help.
F2> key to provide
Security Option
The security option in the OSD Control of the UNIMUX 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 if the user has no activity. 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.
For more on security, see page 19.

In order to control the switch with the keyboard, Command Mode must be enabled. To enable Command Mode from the
keyboard:
(ACCENT/TILDE
Press
All the status lights on the keyboard will illuminate to indicate that Command Mode is enabled. At this point, the Command Mode
menu will be displayed.
The Command Mode menu (see Figure 9) lists all CPUs by name and port number. Only 8 ports are listed on the screen at a
time. To view the other portions of the list, scroll using the arrow keys on the keyboard or use the mouse to click on the arrows on
the scroll bar in the OSD menu. When the Command Mode main menu is displayed, the first displayed port in the list will be the
port the current user is connected to, followed by the next seven consecutively numbered ports. (Alternatively the list may be
sorted alphabetically- press the letter <O> to toggle sort method.) The names of accessible ports are displayed with blue
characters. If Security is activated, the access rights for the user logged-in may not include all ports. Names of restricted access
ports are displayed in black.
Note: In a cascaded system
switch will be displayed instead of the name of that port of the master switch. This rule applies recursively to all slave
switches. If one of the slave switches is powered-OFF during operation, the Status field in the ports name list will
display question marks. In this situation, the user should either power-ON the slave switch or send an Update
Configuration Command (<Ctrl> + <Tab>). If the slave switch is powered back ON without updating the configuration
and security is enabled, the text in the window for CPU type and power status will turn red until the configuration is
updated. (The red text indicates that the slave switch was logged out.)

Scan Mode
Using Scan Mode, the user can automatically switch from one CPU to another in predetermined configurable time intervals. The
CPU ports to be scanned are easily selected provided the user has access to them. At initial startup, the user as access to all
CPU ports by default.
To activate or deactivate Scan Mode press <S> from the Command Mode menu. The text shown in the menu
(see Figure 10) will toggle between “Scan=N” and “Scan=Y”, each time the <S> key is pressed. When “Scan=Y” is shown,
Scan Mode is active. When “Scan=N” is shown, Scan Mode is OFF.
From the Settings menu (see page 14) press <S> to access the “Scan List”. The Scan List enables the user to select specific
ports to be active in Scan Mode. While active, the user will have full device control of the connected port. Only the selected
ports will be scanned in Scan Mode.
The “Scan List” is a check list with all the port numbers displayed
• unchecked box = the corresponding port is not in the scan list
• checked box = the corresponding port is in the scan list
From the “Scan List” the user can:
• toggle the state of the selected port (press <Spacebar>)
• select all ports to be scanned (press <A>)
• deselect all ports so that none are scanned (press <N>)
• find a specific port to either select or deselect (press <F> , then any
alphabetical or numeric character to locate the desired port).
Figure 14- Scan List
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 Settings
Menu on page 14 for configuring the scan dwell time.
To return to the Settings menu, press <Esc>. The scan selection list is automatically saved.
Note: The scan dwell time set by the user only affects 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.

NTI UNIMUX MULTI-USER KVM SWITCH
Broadcast Mode
To activate or deactivate Broadcast Mode press <B> from the Command Mode menu. The text shown in the menu
(see Figure 10) will toggle between “BCast=N” and “BCast=Y”, each time the <B> key is pressed. When “BCast=Y” is shown,
Broadcast Mode is active. When “BCast=N” is shown, Broadcast Mode is OFF.
Broadcast Mode enables the user to type characters to more computers simultaneously. From the Settings menu (see page 14)
press <B> to access the “Broadcast List” where the user can edit the list of ports that receive data in Broadcast Mode.
The “Broadcast List” is a check list with all the port numbers displayed
• unchecked box = the corresponding port is not in the broadcast list
• checked box = the corresponding port is in the broadcast list
From the “Broadcast List” the user can:
• select all ports to be broadcasted to (press <A>)
• deselect all ports so that none are broadcasted to (press <N>)
• select only a limited number of ports to be broadcasted to
• find a specific port to either select or deselect (press <F> , then any
alphabetical or numeric character to locate the desired port).
Figure 15- Broadcast List
A port doesn’t receive broadcast data if one of the following conditions is true:
- the port is not in the Broadcast 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.
Note: The mouse will be disabled while in Broadcast Mode.
To return to the Settings menu, press <Esc>. The broadcast selection list is automatically saved.
Sharing Mode
To activate or deactivate Sharing Mode press <H> from the Command Mode menu. The text shown in the menu (see
Figure
10) will toggle between “Sharing=N” and “Sharing=Y”, each time the <H> key is pressed. When “Sharing=Y” is
shown, Sharing Mode is active.
Note: If Security is enabled for a User port, then the administrator will be the only one that can activate or deactivate
Sharing Mode for that port.
Sharing Mode enables two or more users to access the same CPU port. Enabling Sharing Mode will only effect the logged-in
user and can only be enabled if security for that user port is disabled. If Sharing Mode is disabled, the user cannot switch to a
CPU port that is already connected to by another user.
When a CPU port is connected to by more than one user, the user who is currently typing or moving the mouse has access to the
CPU port and other users cannot use it. The active user will give up access to the CPU after 5 seconds of no activity from the
keyboard or mouse if another user with Sharing enabled wants to take control. Any other connected user with Sharing enabled
can gain access to the idle CPU.
When “Sharing=N” is shown, Sharing Mode is OFF.
Normal Mode
When the UNIMUX 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 UNIMUX switch.

After pressing the key, a confirmation message will appear. The administrator should press <Y> (Yes) to validate the selection or
<N> (No) to cancel it.
Pressing <Esc> will return to the Administration Mode menu.
Power cycle the UNIMUX for the reset to take effect.
Select Keyboard Language
To enter the Select Language menu (see Figure 30) press K from the System Configuration menu described on page 21.
Only the administrator has the Select Language menu option.
The Select Language menu enables the administrator to select a specific
keyboard 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 UNIMUX. 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 UNIMUX 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.

NTI UNIMUX MULTI-USER KVM SWITCH
Security Configuration
The UNIMUX can be configured to either have no security enabled such that any user can connect to the UNIMUX, or have
security enabled such that a user must have a login name and password in order to enter Command Mode and make a
connection with an accessible CPU. Only the administrator has access to Security Configuration.
Within Security Configuration, the administrator has three options:
Function Keystroke
Enable security just for the user port
that his currently connected through
Enable Global Security- security
enabled on all user ports
Disable Global Security- security
disabled on all user ports
Return to previous menu

D
Esc
Figure 31- Security Configuration
If Security is disabled for the port the user is connected to, and the
user attempts to login to Command Mode with the command key, the
login screen will include the instruction “Press F1 to Autologin”.
With security disabled, Autologin provides full access to all connected
CPUs and all users except the administrator must use it to login.
When security is enabled, Autologin is not available and the user must
login using the administrator assigned user name and password. The
user will have access to only those CPU ports as configured by the
administrator.
If Global security is disabled, and security for the port the user is
connected through is enabled, the user will only need to provide a
username and password when connecting through that user port.

NTI UNIMUX MULTI-USER KVM SWITCH
Keyboard Mapping
The keyboard configuration of each CPU is saved in the UNIMUX 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.

NTI UNIMUX MULTI-USER KVM SWITCH
RS232 CONTROL
RS232 enables the UNIMUX to be remotely controlled via RS232. To control the UNIMUX via RS232 the user has three options:
• write a program that runs on a PC using the Command Protocol (page 31)
• use the Matrix Switcher's Control Program (page 32) provided on the CD
• use the SerTest or RMTEST programs (pages 32 and 34) provided on the CD
Remote Connection
The RS232 Interface is designed to meet the RS232C standard and can be controlled from any host CPU or other controller with
an RS232 communications port. The pin-out for the DB9 connector on the unit is as follows:
RS232 Connector (DB9 FEMALE)
PIN SIGNAL FUNCTION
1
None no connection
2 TXD Transmit Data (RXD at host)
3 RXD Receive Data (TXD at host)
4 DSR Data Set Ready
5 GND Signal Ground
6 DTR Data Terminal Ready
7 CTS Clear to Send
8 RTS Request to Send
9
NOTE: Security must be disabled or user access granted on the port(s) to be selected by RS-232 control.
On the DB9 female connector, pins 1 (DCD), 4 (DTR), and 6 (DSR) are shorted and pins 7 (RTS) and 8 (CTS) are shorted.
Therefore, CPU 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, connect a Matrix-Y-1 cable (sold separately) between the CPU
and the first switch, and between each switch (as shown in Figure 34).
none no connection
Baud Rate
The baud rate can be changed by selecting MENU on the front panel keypad. Then select 1 for SET BAUD RATE and select the
desired baud rate of 9600, 4800, 2400, or 1200. A data protocol of 8 data bits, no parity, and 1 stop bit is used for
communications.
Unit Address and Daisy chaining
To allow multiple units to be controlled from a single host port, the RS232 control interface is designed to allow "daisy chaining" up
to 15 units using an NTI Matrix-Y-1 cable. By setting the appropriate unit address with the keypad, each unit can be given a
unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command.
To set the unit address;
1. select MENU on the front panel keypad,
2. select 2 for SET UNIT ADDRESS,
3. type the address number (1-15),
4. press <ENTER> on the front panel keypad.

Autostatus
When Autostatus is enabled, any output-to-input connection change in the UNIMUX will cause an Autostatus message to be sent
via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"
Example of an Autostatus message:
pc 01,01:04<CR>
which means "At the switch with unit address 01, the user port 01 has changed connection to CPU port 04."
Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the
administrator.
Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (below).
By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the
UNIMUX is interrupted.

NTI UNIMUX MULTI-USER KVM SWITCH
CASCADING
The UNIMUX USB Matrix switch can be expanded to access up to 1024 CPUs by cascading multiple units together. As many
switches as there are CPU ports may be connected to a UNIMUX USB Matrix switch. (See Figure 36) All downstream switches
are referred to as "slaves" in a cascaded system. The only additional hardware required to cascade switches is a set of device
and monitor cables for each “SLAVE UNIT” (see MATERIALS on page 2). All CPUs and switches can then be controlled by
users using OSD commands with Command Mode.
Limitations
The front panel keypad is only used to operate standalone switches. To control a cascaded network of switches, only the OSD
commands within Command Mode will be recognized.
The Matrix Switcher's Control Program (page 32) cannot be used to control cascaded switches. It can only be used with a
standalone switch.
RS232 control (page 29) cannot be used between cascaded switches. RS232 control can only be used between standalone
switches.
Users connected to accessible ports on downstream slaves (i.e. ports not connected to the master) will not be able to control
switches or CPUs connected upstream. Only control over CPUs and slaves downstream from a user's connection point will be
enabled. (See Figure 36)
Slaves connected downstream from a master must be switches with at least as many user ports as the master. I.e. If the master
is UNIMUX-4X32, connected slaves can be any switch with 4 or more user ports.
Exception: If the master is a single user UNIMUX switch, slaves connected downstream can be any size multi-user
UNIMUX switch (see Figure 37).

Cable Connections
The same cable used to connect a CPU to the UNIMUX is used to connect two UNIMUX switches together- USBVEXT-xx-MM.
No other cables will be necessary. To connect a slave to a master
1. Connect the USB-A-male end of the USBVEXT-xx-MM to the USER 1 port on the slave.
2. Connect the 15HD male at the same end of the USBVEXT-xx-MM cable to the MONITOR 1 port on the slave.
3. Connect the USB-B-male end of the USBVEXT-xx-MM to the CPU 1 port on the master.
4. Connect the 15HD male at the same end of the USBVEXT-xx-MM to the VIDEO 1 port on the master.
Repeat this procedure for each USER and MONITOR port on the slave that is desired to be controlled through the master. Any
USER and MONITOR ports that do not get connected to the master can be connected to by users. Users connected to a slave
downstream from the master will control only the CPUs directly connected to that slave switch (i.e. users 5 and 6 in Figure 37 can
only control CPUs 25-40).

Operating Cascaded Switches
Immediately after powering-ON the Master switch, the following splash screen will display on the monitor:
All the downstream switches should be powered ON before pressing any key. If there are USB extenders connected, they should
also be powered ON. An extra time of about 5 seconds after powering-ON the last unit may be needed to complete the USB
enumeration process. If the switch is a standalone unit (no downstream switches connected), the key could be pressed
immediately.
When a key is pressed, the master switch will start the process of detecting the configuration. This could take several seconds,
depending on how many switches are connected together. When configuration update is ready, the splash screen disappears and
the system is ready to operate. (If security mode is activated, the login window will be displayed on the screen). The updateconfiguration function can be recalled at any time by entering into Command Mode and pressing the <F5> key.
Note: The front panel keypad is used to operate only standalone switches. To operate a cascaded network of switches
use only OSD commands from Command Mode (see page 11).
Note: Matrix Switcher's Control Program (page 32) cannot be used to control cascaded switches. It works only with a
standalone switch.
After completing the configuration detection, the splash screen is turned OFF and the switches can be operated. All configuration
can be controlled from the keyboard, mouse and monitor through OSD menus (page 11).
SUN RAY SUPPORT
The UNIMUX USB Matrix switch fully supports SUN Ray CPUs, however, if a lack of horizontal mouse movement may be
experienced . If this occurs, enable MAC mode (page 21) for the port that the SUN Ray is connected to. This should enable
proper mouse movement.
