RACK MOUNTING INSTRUCTIONS
This NTI switch was designed to be directly mounted in a rack and includes a mounting flange to make attachment easy.
Install 4 cage nuts (supplied) to the rack in locations that line up with the holes (or slots) in the mounting flange on the NTI switch.
Then secure the NTI switch to the rack using four #10-32 x3/4” screws (supplied). Each screw should be of sufficient length to
go completely through the NTI mounting flange, rack frame and fully engage all threads in the captive nut. Be sure to tighten all
mounting screws securely.
Do not block power supply vents in the NTI switch chassis (if provided). Be sure to enable adequate airflow in front of and
behind the NTI switch.
Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.

2. Connect the user devices to the USB type A female ports labeled with the USB symbol ( ) on the rear of the UNIMUX
switch (see Figure 4 ). Ensure that the monitors and related user devices are connected to ports from the same device port
group.
Note: If there are three (3) USB type A female ports present (models with touch screen support only), then the third USB
port is available for connection of a USB cable from a touch screen type monitor. The USB ports are not device specific,
so the mouse, keyboard, and USB cable from a touch screen type monitor (or other suppported device) can be
connected to any of the available USB ports present.
Note: If device cables are not long enough to reach the UNIMUX switch, they can be extended either 5 or 10 meters
using either 1 or 2 NTI USB2-AA-5M Active USB 5 Meter Extensions (see Figure 5)- purchased se parately. Using USBC5-LC you can extend device cables up to 150 feet. Contact your NTI salesperson for more details by calling (800) 7428324 (800-RGB-TECH) or (330) 562-7070 or visit our website at http://www.networktechinc.com

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 2048x1536 with no
degradation – guaranteed. The front panel LCD indicates the port to which each user is attached. The UNIMUX can be
controlled by four methods:
• keypad control
• OSD control
• RS-232 control
• Telnet Interface
Keypad Control
with LCD via front panel
via the user devices (applicable only to models with video support)
(see page 38)
- via command line interface (page 44)
The front panel keypad and LCD (see Figure 15) 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 1200,2400,480 0,96 00,19200,
38400,57600, or 115200 baud and the unit address to be set to 1 - 15. See RS-232 cont rol on page 38.
* 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 disp laying 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

OSD CONTROL
(Not available on models without video support)
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.
Guidelines for Navigating OSD Menus
Throughout this manual, various rules apply to navigating 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 to 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 an d press
<Enter> to enter the field for editing, and press <Enter> again to exit th e edit field.
the keyboard .
• To exit (and step back 1 menu) from any menu, press <Esc>
• All screens that include “F1:Help” for context-sensitive help will also respond to pressing the <F2> key to provide
“Global Help” screens with basic menu navigation help.

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 activ ity. 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 26.

NTI UNIMUX MULTI-USER KVM SWITCH
Initial startup
When the UNIMUX is first powered ON, a splash screen similar to the following will appear:
Press any key and the UNIMUX will connect you to the first CPU port with a connect ed CPU that is powered ON.
To access Command Mode and connect to a different port or perform other user access functions (see below), press <Ctrl> +
<`> (accent/tilde key).
User Access Functions
Command Mode
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 16) 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
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 config urable 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 <Ctrl> + <S> from the Command Mode menu. The text shown in the menu (see
Figure 17) will toggle between “Scan=N” and “Scan=Y”, each time the <Ctrl> + <S> keys are 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 21) press <S> to access the “Scan List”. The Scan List enables the user to sel ect specific
ports to be active in Scan Mode. While active, the user will have full device contr ol 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 21- 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 21 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 (or other USB device) 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 <Ctrl> + <B> from the Command Mode menu. The text shown in the menu
(Figure 17) will toggle between “BCast=N” and “BCast=Y”, each time the <Ctrl> + <B> keys are 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 21)
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 22- 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
- 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 17)
will toggle between “Sharing=N” and “Sharing=Y”, each time the <H> key is pressed. When “Sharing=Y” is shown,
Sharing Mode is active. When “Sharing=N” is shown, Sharing Mode is OFF.
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 enable d
can gain access to the idle CPU.
Note: Sharing Mode is disabled automatically and cannot be used when non-HID devices (whiteboard, smartcard, or
touchscreen monitors) are connected.
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.

Select Keyboard Language
To enter the Select Language menu, press K from the System
Configuration menu described on page 28.
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.
Figure 39- Select Language menu
• To manually program a specific language, select a langua ge 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.
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

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.

If Global security is enabled, the user must provide the username and password when connecting through any us er port.
Serial Baud Rate
The serial baud rate for the UNIMUX can be changed by pressing <B> from the System Configuration menu. In order to control
the UNIMUX via RS232 (page 38), the baud rate must be set the same as the communication port on the control terminal
attached to the UNIMUX (page 11)
The baud rate value can be set to 115000, 57600, 38400, 19200, 9600, 4800, 2400, or 1200. A data protocol of 8 data bits, no
parity, and 1 stop bit is used for communications. With the edit field highlighted, press the <Left arrow> or <Right arrow>
to change the value of the baud rate.
Note: The baud rate can also be changed from the RS232 Command Protocol (see page 38).

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 40)
• use the Matrix Switcher's Control Program (page 41) provided on the CD
Remote Connection
The RS232 Interface is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an
RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:
RS232 (RJ45) CONNECTOR
PIN SIGNAL FUNCTION
1 - No connection
2 - No connection
3 RX+ Receive data (TXD at host)
4 GND Ground
5 - No connection
6 TX+ Transmit data (RXD at host)
7 - No connection
8 - No connection
NOTE: Security must be disabled or user access granted on the port(s) to be selected by RS232 control.
A 5 foot patch cable and two adapters, RJ45-to-DB9 and RJ45-to-DB25, have been provided for connection to most CPUs (see
page 11). 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 45).
Baud Rate
The baud rate can be changed by selecting MENU on the front panel ke ypad, using the OSD menu, or from the RS232
commands (page 40). The baud rate can be set to 115000, 57600, 38400, 19200, 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 Loop Back
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. Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter (provided with
the RS232 option) and the CPU as shown in Figure 45. By setting the appropriate unit address (page 35) , 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.

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 output (01) has changed connection to input 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.

provided on the web page that appears when you insert the instruction manual CD provided into your CD ROM drive. Either click
on the link or browse the CD to locate the NTIDiscover.jar file. The Discovery Tool can be run from the CD or it can be
saved to a location on your PC. Either way, to open it just double-click on the file NTIdiscover.jar . This will open the NTI
Device Discovery Tool.
Note: The Device Discovery Tool requires the Java Runtime Environment (version 6 or later) to operate. A copy of Java
version 6 is provided on the CD and a link to the web page from which it can be downloaded and installed is also on the
CD.
Note: The computer using the Device Discovery Tool and the NTI Device must be connected to the same physical
network in order for the Device Discovery Tool to work. If no devices are found, the message “No Devices Found” will
be displayed.
Tip: If your Windows program asks which program to open the NTIDiscover.jar file with, select the Java program.

NTI UNIMUX MULTI-USER KVM SWITCH
CASCADING
The UNIMUX USB Matrix switch can be expanded to access up to 512 CPUs by cascading multiple units together. 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 3). 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.
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 48)
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.
In order for each user that is connected to the master to view and control CPUs connected to slaves, a number of user ports from
each slave equal to the number of user ports on the master must be connected to the master. i.e. If the master has 2 user ports,
and the slave has 4 user ports, then at least 2 of the 4 user ports on the slave must be connected to the master.
Exception: If the master is a single user UNIMUX switch, slaves connected downstream can be any size multi-user
UNIMUX switch (see Figure 49).

Cable Connections
The same cable used to connect a CPU to the UNIMUX is used to connect two UNIMUX-UHD switches together-
HDUSBVEXT-xx-MM. No other cables will be necessary. To connect a slave to a master
1. Connect the USB-A-male end of the HDUSBVEXT-xx-MM to the USER 1 port on the slave.
2. Connect the 15HD male at the same end of the HDUSBVEXT-xx-MM cable to the MONITOR 1 port on the slave.
3. Connect the yellow 15HD male end of the HDUSBVEXT-xx-MM to the CPU 1 port on the master.
Repeat this procedure for each USER and MONITOR port on the slave that is desired to be controlled throug h 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 48 can
only control CPUs 9-24).

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 config uration. This could take several seconds,
depending on how many switches are connected together. When co nfiguration update is complete, the splash screen disappears
and the system is ready to operate. (If security mode is activated, the login window will be display ed 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. T o operate a cascaded network of switches
use only OSD commands from Command Mode (see page 18).
After completing the configuration detection, the splash screen is turned OFF and the sw itches can be operated. All configuration
can be controlled from the keyboard, mouse and monitor through OSD menus (page 18).
SUN RAY SUPPORT
The UNIMUX USB Matrix switch fully supports SUN Ray CPUs, however, a lack of horizontal mouse movement may be
experienced . If this occurs, enable MAC mode (page 28) for the port that the SUN Ray is connected to. This should enable
proper mouse movement.

NTI UNIMUX MULTI-USER KVM SWITCH
REMOTE USER SUPPORT VIA CAT5
If the UNIMUX includes support for remotely locating users using CAT5 cable and an ST-C5USBV-R-300 extender (page 11), the
user can be up to 300 feet away and still have full control over the UNIMUX. From the display and devices connected to the STC5USBV-R-300 the user can configure the UNIMUX, control which CPU the user has a connection to (as previously described in
this manual), and adjust the video quality of the extended signal.
Command Mode
The remote user can adjust video quality by first entering Command Mode.
To enter Command Mode, simultaneously press the left and right <Shift> keys on the keyboard connected to the STC5USBV-R-300. The keyboard LEDs will illuminate.
To exit Command Mode, press <Esc>.
Video Quality Adjustment
It is possible that on initial startup the image on the monitor will not be as crisp as the image normally is. This is due to the
frequency characteristics of the CAT5 cable. It may be necessary to enter Command Mode (described above) and press
the ▲ (up arrow) or ▼(down arrow) keys on the remote keyboard until the image is crisp and clear.
• Press ▲ (up arrow) key if the image is not crisp and clear enough.
• Press the ▼(down arrow) key if the image has been over-corrected (such that horizontal lin es appear to trail or
shadow at the edge of an open window).
• A momentary press of either key will make a minor change in the image.
Ultimately, the image quality should improve to a satisfactory level. Once the adjustment is made, it should not be necessary to
change it again, as the new settings are stored in memory and become the default settings with each startup. To exit Command
Mode, press <Esc>.
Note: For additional quality adjustment, it may be necessary to adjust the brightness and contrast settings of the
monitor.
Extended Video Resolution
The video resolution supported by the ST-C5USBV-R-300 is as follows:
Maximum Resolution w/ CAT5/5e/6 UTP
(refresh frequency 60Hz)
Maximum Resolution w/ CAT5/5e STP
(refresh frequency 60Hz)
Video Compatibility WUXGA,UXGA,SXGA, XGA, SVGA, VGA
1024 x 768 @ 60Hz- up to 300 feet
1600 x 1200 @ 60Hz- up to 150 feet
1920 x 1440 @ 60 Hz- up to 100 feet
1024 x 768 @ 60Hz- up to 300 feet
1280 x 1024 @ 60Hz- up to 150 feet
1600 x 1200 @ 60Hz- up to 100 feet

NTI UNIMUX MULTI-USER KVM SWITCH
FIRMWARE UPGRADE PROCEDURE
This procedure describes how to upgrade the firmware in this UNIMUX switch. If you are not certain whether this UNIMUX has
the most up-to-date firmware available, see page 60 for instruction on how to determine what versi on the UNIMUX has. All
versions of firmware can be downloaded from the NTI firmware download website at
http://www.networktechinc.com/download/d-srvsw-usbvst-uhd.html
The UNIMUX switch has 3 types of micro-controllers:
1. Main User Controller – there is only one on each UNIMUX and it will be upgraded with a binary file named unimux-muhd csx-x.bin (where x-x is the rev number).
2. HID Port Controller – there is one HID Port Controller for each CP U port available on the switch – it will be upgraded with an
Intel hex file named unimux-muhd-cpkmx-x.hex. Each CPU port is upgraded independently.
3. Vendor Specific Port Controller – there is one such controller for each CPU port available on the switch – it will be upgraded
with an Intel hex file named unimux-muhd-cpvdx-x.hex. Each CPU port is upgraded independently.
The UNIMUX firmware has a bootloader which can be used for fi rmware upgrades. The bootloader resi des in a protected area of
Flash memory, so that if the upgrade fails for any reason, the bootloader will still be available to be used to re-program the entire
unit.
Upgrades can be made to the User Controller, HID Port Controller, or V endor Specific Port Controller on an individual basis as
needed. Not all CPU ports must be at the same revision level for the UNIMUX to work, but it is highly recommended that if you
upgrade one CPU port, you upgrade all CPU ports on a switch.
.

NTI UNIMUX MULTI-USER KVM SWITCH
Update the User Controller Firmware
Note: The User Controller Firmware update only needs to be done once, whether the UNIMUX switch is a single-user, or
a multi-user model.
The user controller firmware comes as a file in binary format and has the extension .bin. (i.e. filename.bin). To upgrade the user
controller to this file, press <u> from Terminal window. The following message should appear on the screen:
Erasing flash memory…
Memory successfully erased
Send .bin file using Xmodem protocol..
At this point the binary file unimux-muhd-csx-x.bin has to be sent. To do this, from HyperTerminal:
1. go to “Transfer” menu in the Menu Bar of the HyperTerminal window
2. click the item “Send File …”
3. in the dialog box which pops up on the screen, browse for the file to be sent and select it
4. select “Xmodem” from the Protocol drop-down menu
5. press “Send” button
The transmission will start shortly. Wait until the transmission is finished. There will be some pauses during transmission, since
the processor writes blocks of 4KB.
When the transmission is complete, the HyperTerminal window should show the following status message and return to the menu
prompt:
Device successfully programmed!
>
To exit from the bootloader, press <x>.
Update the HID Port Controller Firmware
The HID port controller firmware comes as a file in Intel Hex format and has the extension .hex (i.e. filename.hex). To upgrade
any of HID controllers (there is one per CPU port) with this firmware, press <p> from the terminal window. The following message
should appear on the screen:
Send .hex file using XModem protocol...
At this point, the hex format file unimux-muhd-cpkmx-x.hex has to be sent, using HyperTerminal and the same procedure as
before. When the transmission is done, the following message will be shown in the HyperTerminal window:
File transfer OK!
Please, type the two-digit number of the port to be updated,
<A> to program all or <X> to exit
(the two-digit number should be between 01 and nn,
where nn is the number of available ports):
58
NTI UNIMUX MULTI-USER KVM SWITCH
To program only one device (CPU port), the corresponding port number must be typed (two-digit number, zero leading, number
between 01 and the last CPU port number, depending on switch size. To program all devices, just press <a>).
The following message will be shown on the screen (it may take about 12 seconds to program each device):
Programming device, please wait...
Device ID: 0x001E
Device successfully programmed!
The bootloader will then ask again for a port number.
To program another port, type the two-digit number of the port,
To exit from this function and the bootloader, press <x>.
If <a> was pressed instead of a single port number, and all devices were programmed, the message above will be re peated for
each port that was programmed. After all are programmed, unless the switch has 32 CPU ports, the following message will be
shown on the screen
Programming device, please wait...
Device ID: 0x0000
Device failed!
Error Code 1
This is shown because the bootloader continues to look for devices until it has found up to 32 (the maximum number of possible
CPU ports a single UNIMUX can have). If it doesn’t find another port, the procedure will fail and discontinu e. On switches with
fewer than 32 ports, this is normal.
To exit from the bootloader, press <x>.
Update the Vendor Specific Port Controller Firmware
Updating the vendor specific port controller firmware is similar to updating the HID port controller firmware (described on page 3).
The only differences are that key <v> is used to enter this command and the hex file to send will be unimux-muhd-cpvdx-x.hex
To exit from the bootloader, press <x>.
59
NTI UNIMUX MULTI-USER KVM SWITCH
Read the Checksum of HID or Vendor Specific Port Controller Firmware
Reading firmware checksum is useful to determine the version of software running on port controllers. While the firmware revision
for user controller can be found on the UNIMUX splash screen when it is powered-ON, the firmware revision of port controllers is
not displayed anywhere. Reading checksum is an easy way to identify the current firmware revision in your UNIMUX and to
determine if a new firmware revision is available for download.
To read the checksum, type <s> for HID port controllers or <t> for vendor specific port controllers, at the bootloader prompt. The
following message will be displayed:
Please, type the two-digit number of the port to be checked,
<A> to check all or <X> to exit
(the two-digit number should be between 01 and nn,
where nn is the number of available ports):
To read the checksum for only one device, type the number of the port (two digits, leading 0). To read the checksum for all ports
type <a>.
The device ID and the checksum will be displayed in the following format:
Device ID: 0x001E
Device Checksum: 0x3AB1
The checksums for all revisions of UNIMUX firmware can be found on the NTI download webpage at
http://www.networktechinc.com/download/d-srvsw-usbvst-uhd.html
To exit from the bootloader, press <x>.
