INSTALLATION
Rack Mounting Instructions
The RACKMUX was designed to be mounted to a rack and includes mounting flanges to make attachment easy.
1. Determine the mounting height in the rack for the drawer. It should be a height comfortable to use the keyboard and see the
LCD display. Mark holes in each of the 4 corner cabinet rails at points all level with each other.
2. Secure the rear brackets to the rear rack cabinet rails. Apply the top screws (not supplied) for each bracket to the holes
marked in step 1.
3. Lift the keyboard into position and line the studs on the left and right sides up with the slotted openings in the rear bracket.
Apply the nuts (supplied) to the studs but do not tighten the nuts yet.
FYI: There are 3 mounting studs provided on each side of the RACKMUX. Depending on the depth of the rack and
distance apart of the cabinet rails, the position of the rear bracket may make all 3 studs available for use. In this case,
apply the 2 nuts to the studs furthest apart from each other on each side.
4. Slide the drawer in until the top holes in the front bracket flanges line up with the holes marked in step 1. Secure the front
brackets on the drawer to the front cabinet rails. Be sure to tighten the screws securely. Then tighten the nuts applied in step 3.

NTI RACKMUX Console Drawer with UNIMUX Switch
USING THE RACKMUX
Once the RACKMUX is properly connected, the UNIMUX switch will enable a connection to be made between the attached CPUs
and the monitor, keyboard, and mouse.
The UNIMUX switch can be controlled by two methods:
•
•
keyboard control through Command Mode
mouse clicks from within some menus of Command Mode
Keyboard Control
Keyboard control of the UNIMUX switch is achieved using Command Mode - operated using the keyboard and mouse in
conjunction with 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 UNIMUX switch to connect the user to any one CPU connected to the switch. Pressing the <Esc> key
will exit Command Mode. The following instruction describes how to use the menus to operate the UNIMUX switch.
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 Option
The security option of the OSD Control 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. Security can be activated from the Maintenance Mode menu (page 17) 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.
If the security option is enabled, when the RACKMUX is powered up the user will be prompted for a username and password to
continue. If the security option is not enabled the monitor will display the desktop image for the connected CPU and the user
can continue with normal operation of the connected CPU.
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. This provides a visual way to control the
UNIMUX switch using the keyboard and mouse.
The administrator , when setting the UNIMUX switch 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
•
password = ADMINISTRATOR
Note: The user name for the administrator cannot be changed from "ADMINISTRATOR".

Once logged-in, follow the instructions on pages 8 and 9 for setting up
users and changing the password. Within the Administration Mode the
administrator can setup each of the users and the limitations of their
use of the individual CPUs attached to the switch.
Figure 4- Administrator Login screen
When a standard user powers up the system a security screen will appear if security has been enabled by the
administrator. The user will need to login to the switch 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 switch administrator for this
information. Once logged-in a user can follow the Command Mode functions described on page 10 to control the switch 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. This mode will
also disable use of the front panel until the user logs in.
Function:
Keystroke:
A-Z
0-9
Adds a character to the
user name/password
(Type any alphabetical or numeric character)
Removes previous character
from the user name/password
Backspace
Enter
Submit user name/password
Exit USER LOGIN and return
to previous mode. This function
is only available if security is
not currently active.
Esc
If the password submitted is incorrect, the user will not
be able to proceed.
If the password submitted is correct, the user will
proceed to Normal Mode.

Alternate Command Hot Key
To enable the administrator to assign a key in addition to the <`> (accent key) to use with <Ctrl> to enter into OSD Command
Mode, an Alternate Command Hot Key option is provided. The default factory setting for this option is <`> (disabling the option).
To select an Alternate Command Hot Key, press <X> from Administration Mode menu (page 8). A window will open and the
administrator will be prompted to press a key. After pressing the key, a confirmation message will appear. The administrator
should press <Y> (Yes) to validate the key as the Alternate Command Hot Key, or <N> (No) to select another key. Pressing
<Esc> will return to the Administration Mode menu.
Only the administrator is allowed to set or change the Alternate Command Hot Key. This function must be set individually for each
of the USB User Device ports on the UNIMUX.
FYI: The Alternate Command Hot Key does not replace the <`> (accent) key, it just works as another way to enter into
Command Mode. After setting it, the user can enter into Command Mode either with <Ctrl> + <`> or with <Ctrl> +
<Alternative Command Hot Key> combination. To disable it, the administrator should set <`> as the Alternate Command
Hot Key.
USER ACCESS FUNCTIONS
Introduction
The OSD menu enables a user to name the CPUs connected to the UNIMUX switch and connect to them using that name. The
OSD is positioned on the 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 operate the UNIMUX switch to have the switch cycle through 3 extended
modes of operation: COMMAND, BROADCAST, and SCAN .
Command Mode
When entering the 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 UNIMUX switch.
The list below describes the OSD Command functions available from the keyboard after entering Command Mode:

Broadcast Mode
To activate Broadcast Mode press <Ctrl> + <B> from the Command Mode menu.
Broadcast Mode enables the user to type characters to more computers simultaneously. From the Change Settings menu (see
page 13) the user can edit the list of ports that receive data in Broadcast Mode. A port doesn’t receive broadcast data if one of the
following conditions is true:
- the port is not in the Broadcast Mode 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.
Scan Mode
To activate Scan Mode press <Ctrl> + <S> from the Command Mode menu.
When in Scan Mode the switch scans to each port with a CPU powered-ON. The port with the CPU powered-ON remains active
while in use until it becomes idle for the configured dwell time (default time-out period is 5 seconds) before switching to the next
powered-ON CPU port. See Command Mode section above for configuring the scan dwell time.
Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active
port.
Note: The scan dwell time set by the user only effects that user and has no effect on other switch users.
Normal Mode
When the UNIMUX switch is not in Command or Scan mode, the user is in Normal Mode, controlling the CPU to which the user is
connected through the UNIMUX switch.
Edit Mode
NOTE: Edit Mode will only be accessible if the administrator is logged in.
To activate Edit Mode press <Ctrl> + <E> from the Command Mode menu.
Edit Mode enables 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).

Language Selection
NOTE: The LANGUAGE SELECTION option will only be accessible if the administrator is logged in.
To enter the Select Language menu press <L> from the Change
Settings menu described on page 14.
The Language Selection menu enables the user to manually
configure the UNIMUX to emulate a specific international Sun
keyboard regardless of what actual keyboard is connected. This
is recommended when the CPU needs the layout code (i.e. a
SUN CPU) and the keyboard doesn't have an explicit layout code
(i.e. Windows keyboards).

MAC Ports Configuration
NOTE: The CONFIGURE MAC PORTS option will only be accessible if the administrator is logged in.
MAC Ports Configuration menu enables the administrator to select specific ports to be connected to MAC CPUs for passing
mouse information to the MAC CPUs. This is useful when the user wants to use mouse drivers provided by the mouse vendor,
which allows the use of programmable functions for each button. Ports should be configured at installation time or whenever
necessary. After setting, the configuration is stored in non-volatile memory and will be retrieved whenever the switch is power
ON. When the port is connected to a Windows or SUN CPU, this configuration SHOULD BE DISABLED. By default, all ports are
configured as non-MAC CPUs (Windows and SUN).
NOTE: If a port is configured as connected to a non-MAC CPU, but is in fact connected to a MAC CPU, the mouse will
still work as a generic mouse. No special functions provided by software drivers will be available.
To enter the MAC Ports Configuration menu, the administrator must press <M> from the Change Settings menu, described on
page 14.
A check list with all the ports numbers preceded by a check-box will be displayed in the window.
•
unchecked box = the corresponding port is set as
connected to a non-MAC CPU
•
checked box = the corresponding port is set as
connected to a MAC CPU
In order to change the status of a port, the administrator has to first
select the port. The selected port is highlighted with a green bar.
To select another port, the administrator can use the arrow keys or
mouse movement. The name of the selected port is displayed at the
bottom left of the menu, right above the yellow bar.
The administrator can toggle the state of the selected check box by
pressing the <Spacebar> or clicking the left mouse button.

F3- Display Information
To display information about a selected port, pressing the <F3> key from within the Command Mode main menu will cause a
window to open. The window will show the name of the port and its position in the system structure, level by level. This is most
useful when cascading switches (for Cascading see page 20). An example of this structure might be
LEVEL 1 : PORT 5
LEVEL 2 : PORT 3
This means that the CPU connected through this port is actually connect through Port 5 of the master switch (Level 1), and
through port 3 of the slave connected to port 4 (Level 2). See Fig. 20 below.

CASCADING
The UNIMUX can be cascaded as shown in Fig. 21 below. Single user or multi-user UNIMUX switches may be connected
downstream (see Figs. 23 and 24). The first switch in a cascaded system is referred to as the "master", while all downstream
switches are referred to as "slaves". The only additional hardware required to cascade switches is a set of device and monitor
cables for each “SLAVE UNIT” (USB-VEXT-xx-MM). All CPUs and switches can then be controlled by users using OSD
commands with Command Mode.
Notes:
•
The UNIMUX used in a RACKMUX cannot be connected in a cascaded system with UNIMUX-USBV-x switches made
prior to 10-1-04.
•
Slaves in a cascaded system must be either all single-user switches or all multi-user switches, but not a
combination of both.
Cascaded Installation
a. Using the 15HD video cable ends of a USBVEXT-xx-MM cable, connect the USB KVM slave's MONITOR port to the master’s
VIDEO 1 port.
b. Using the USB ends of the same USBVEXT-xx-MM cable, connect one of the USB slave’s USB DEVICES ports to the
master’s CPU 1 port.
Note: Only one of the two ports labeled DEVICES on a slave needs to be used in order for cascading to work.
c. Repeat step b. & c. for each additional slave, keeping in mind that each slave will connect to the next available master’s
port (i.e. Slave #2 to master’s VIDEO 2 & CPU 2, etc.) See Fig. 24 on page 22.

FYI: Any USER and MONITOR ports on a multi-user switch connected as a slave that do not get connected to the master
can be connected to by users (for example users 5-8 in Fig. 22). 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 fig. 22 above can only
control CPUs 25-40).

Figure 24- Master to slave cable connections- multi-user switches
Limitations
¾
¾
¾
All switches used as slaves must have the same number of CPU ports (all 4, 8, or 16 CPU ports).
Up to 8 slaves may be connected to form a maximum system size of 152 ports (1x32 port master + 8x16 port slaves).
Slaves must be added to the master in order (slave #1 to master’s port 1, slave #2 to master’s port 2, etc).
FYI: Master Port 1 (with an 8-port Slave connected to it) will become ports 1-8 (1-4 for a 4-port slave). Master Unit Port 2
(with a second 8-port Slave Unit connected) will become port numbers 9-16 (5-8 for a 4-port slave).
¾
The front panel buttons (found on most UNIMUX switches) are only used to operate standalone switches. To control a
cascaded network of switches, only the OSD commands within Command Mode will be recognized.

MOUSE CLICK EQUIVALENTS
To emulate a right button click using Apple 1 button mouse, hold down the Command key (
button.
) while pressing the mouse
Note: Right mouse button emulation must be enabled (see Change Settings on page 14) for this to work.
KEYBOARD FEATURES
The keyboard configuration of each CPU is saved in the UNIMUX switch. For example, if the CPU attached to Port 2 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.
Keyboard-To-Computer Translation
The UNIMUX switch enables a mixture of otherwise incompatible peripheral computer components to be connected together.
This is accomplished by performing keyboard-to-computer translations automatically (i.e. translate the Windows keyboard and
mouse to a SUN type CPU). The chart below shows the capabilities of the keyboard controlling certain CPU types.

International Sun Keyboards
The UNIMUX can recognize international layouts for Sun keyboards. In order to use an international Sun keyboard, follow this
procedure:
1. Power-OFF the CPU from the UNIMUX
2. Connect the international keyboard to be used to the UNIMUX
3. Power-ON the CPU to the UNIMUX
It is also possible to configure the UNIMUX to emulate a specific international Sun keyboard regardless of what actual keyboard is
connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an
explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate the international keyboard
identification number to the CPU by following the instruction on page 16 for Language Selection.
DDC SUPPORT
(Optional)
DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up,
information from the monitor concerning its resolution specifications.
When DDC Support is installed, the DDC information is acquired from the monitor by the UNIMUX switch when the UNIMUX is
powered-up. The DDC information will be made available at every CPU port.
Note: In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch
must be powered up before all attached CPUs.
TROUBLESHOOTING
PROBLEM:
SOLUTION:
Keyboard Errors
Check cable connections on each CPU and the switch.
PROBLEM:
SOLUTION:
No Video
Check cable connections on each CPU and the switch. Verify that keyboard and video connect from each CPU
to matching ports. After reconnecting, CPU may need to be re-booted in order to sense the monitor connection.
