USING THE NTI KEEMUX-USBV-xU KVM SWITCH
Control over the CPUs attached to the NTI KEEMUX-USBV-xU KVM switch is achieved through operation of the KEEMUX-USBVxU KVM switch. Once the KEEMUX-USBV-xU KVM switch is properly connected, the KEEMUX-USBV-xU KVM switch will enable
a connection to be made between the CPUs attached to its VIDEO-x and CPU-x ports and the monitor and input devices
attached to the MONITOR and USB DEVICES ports. The LEDs on the control panel of the KEEMUX-USBV-xU KVM switch will
illuminate depending on which port (and subsequent associated CPU) is being con nected the monitor and input devices. The
choice of which CPU the monitor and input devices will be connected to is determined by controlling the KEEMUX-USBV-xU KVM
switch either through the front control panel on the KEEMUX-USBV-xU KVM switch, by keyboard control, or by optional methods
such as RS232, Infrared, or an On Screen Display (OSD).
7
Page 10
Front Panel Control
There is a touch-switch and LED on the front panel of the KEEMUX-USBV-xU KVM switch for each CPU the switch will
connect the monitor and input devices to. Pressing any touch-switch on the front panel of the KEEMUX-USBV-xU KVM switch will
connect the selected CPU to the monitor and input devices.
Holding down any front panel touch-switch for more than 2 seconds will cause the KEEMUX-USBV-xU KVM switch to cycle
through all modes of operation including COMMAND, SCAN, and NORMAL (described on page 8). The two MODE LEDs on the
front panel indicate which mode is selected. Release the touch-switch when the LEDs indicate the desir ed mode. When no mode
LEDs are illuminated the user is in Normal Mode controlling directly the CPU to which the user is conn ected through the
KEEMUX-USBV-xU KVM switch.
Keyboard Control
Keyboard control of the KEEMUX-USBV-xU KVM switch can be achieved through either
• Basic Command Mode- Basic Command Mode is operated strictly by using keyboard commands as instructed below. Basic
Command Mode is only applicable if the OSD option is not built into the switch.
-OR-
• OSD Command Mode (OSD is purchased as a separate option)- OSD Command Mode is operated using the input devices in
conjunction with On Screen Display (OSD) menus superimposed onto the monitor. If OSD is built in, use the menus as
instructed on page 11.
By pressing <Ctrl> + ` (accent key), the user can enter Command Mode (either Basic, or OSD). Once in Command Mode, typing
a series of commands will cause the KEEMUX-USBV-xU KVM switch to connect the user to any one CPU connected to the
switch. Pressing the <Esc> key will exit Command Mode.
MODES OF OPERATION
Basic Command Mode
In order to control the KEEMUX-USBV-xU KVM switch with the keyboard connected, Command Mode must be enabled. To enter
Command Mode from the keyboard:
Press

PLEASE NOTE: It is necessary to configure any Sun CPU such that the Sleep Mode is not enabled. If the Sun CPU goes into
sleep mode either automatically or manually, the user must reboot the Sun CPU in order to resume use of the Sun CPU.
To disable the Sleep Mode, perform the following steps:
1. Select "Power Manager"
2. Look for "Device Idle Time Before Power Saving Starts"
3. Select "Always ON"
4. Look for "Override Device Idle Time For:"
5.
Make sure neither "Monitors " nor "Disks" are selected.
OPTIONAL OSD SECURITY ADMINISTRATION
The security features of the optional OSD Control allow an administrator to restrict access to the KEEMUX-USBV-xU switch using
a set of eight user names, and to control access to individual CPUs separately for each user. Security can be activated from the
Maintenance Mode menu (page 14) 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.
Using the Security Feature
If the OSD feature is built into the NTI switch, when entering the Command Mode from the keyboard using the sequence
<Ctrl> + <`> (accent key) the On Screen Display menu will automatically appear on the monitor in addition to illuminating the
Command Mode indicator LED on the KEEMUX-USBV-xU switch. This provides a visual way to control the NTI KEEMUX-USBVxU switch using the monitor and input devices.

OPTIONAL OSD CONTROL
INTRODUCTION
The NTI optional On Screen Display (OSD) allows a user to name the CPUs connected to the KEEMUX-USBV-xU switch and
connect to them using that name from a single keyboard and mouse. The OSD is positioned on the user's 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 KEEMUX-USBV-xU switch to have the switch cycle through 2 extended modes of operation: COMMAND
and SCAN . Two LEDs on the front panel indicate when these modes are enabled.
OSD Command Mode
If the OSD option is installed, when entering the Command Mode from the keyboard using the <Ctrl> + <`> (accent key),
the On Screen Display menu will automatically appear on the monitor in addition to illuminating the indicator LEDs on the KVM
switch. This provides a visual way to control the NTI KEEMUX-USBV-xU switch using the keyboard, monitor, and mouse.

Other Control Options
There are other ways to control the NTI KEEMUX-USBV-xU switch, depending upon which options have been purchased with
the switch, including an Infrared Control, or RS232 . If either of these options have been purchased with the switch, instructions
for that option should have been included with this manual. For more information on these options, refer to the NTI products
catalog, our website at http://www.nti1.com, or contact an NTI sales representative for more details by calling 330-562-7070, or
800-742-8324 (800-RGB-TECH).

Keyboard Mapping
The keyboard configuration of each CPU is saved in the NTI KEEMUX-USBV-xU 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
Port 4 is accessed again.
Keyboard-To-Computer Translation
(See Fig. 8 below for reference.)
The NTI KEEMUX-USBV-xU USB KVM 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 a
MAC keyboard and mouse to a Windows type CPU). The chart below shows the key commands that will be recognized and
translated for the different types of CPUs. Following the chart below, find the character desired to type or function to be
performed, then follow the row across for the key or series of keys to press on the keyboard currently in use.

How To Disable Operating Modes
Two operating modes of the KEEMUX-USBV-xU switch can be disabled if desired. The Command Mode can be disabled
which would also disable the Scan Mode, or, the Scan Mode can be separately disabled leaving Command Mode enabled.
To disable these operating modes, the user must get access to the jumpers block. This block is located close to the dip
switches on the circuit board the keyboards plug into (called the digital board) inside the KEEMUX-USBV-xU.
(See Fig. 9.)

If the unit is a rackmount style, the digital board is located directly beneath the cover of the unit, requiring the user to only remove
the 9 screws from the cover to gain access. With the cover removed, the jumpers block will be easy to locate (see Fig. 9).
Follow the instructions under "CONFIGURING THE JUMPER BLOCK" (page 20) to disable the desired mode(s).
If the unit is in a plastic case, the digital board is located on the bottom of the case, requiring the user to partially disassemble the
unit to gain access to the jumpers block. If the unit has the OSD option (KEEMUX-USBV-xUO), the procedure will be different
than the procedure used if the unit does not have the OSD option.
For models KEEMUX-USBV-xU (no OSD):
