USING THE NTI UNIMUX USB KVM SWITCH
Basic Operation
The UNIMUX switch enables a user or several users (with sharing enabled) 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
1920x1200 with no degradation – guaranteed. An 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 26)
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:
Key Action
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, 2400, 1200 or 300 baud and the
unit address to be set to 1 - 15. See RS-232 control on page 26.
* 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
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.
USR - 3 - CPU - 5 - ENTER
USR - 3 - ENTER - 5 - ENTER
USR - 0 - 3 - 0 - 5

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 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. 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.
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 UNIMUX USB KVM
switch using the keyboard and mouse.
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 Figure 9).
Password and User Name
The factory settings are:
•default user name = ADMINISTRATOR
•default password = ADMINISTRATOR
Note: The username for the administrator cannot be changed
from "ADMINISTRATOR".
Figure 9- User login screen
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. The
administrator can setup each of the users and the limitations of their use of the individual CPUs . within the Administration Mode.
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 Mode functions described on page 16 to control the system of CPUs within the limitations as
determined by the administrator.
