Hardware Installation
This section will guide you through the hardware installation of your KVM Module.
Please read through this section carefully and complete each step in the order listed.
1. Make sure all computers and devices are powered o.
2. Remove/disconnect any existing KVM Module from the rear of the 1UCABCONS
series Rackmount Console.
3. Connect the KVM Module to your 1UCABCONS series Rackmount Console as
directed in it’s user guide.
4. Attach each of your managed computers to your KVM console’s PC ports using
StarTech.com KVM cables. Use the cables to connect one of the PC ports on the back
of the KVM module to the computer’s keyboard/mouse, and video ports.
NOTE: These instructions are for a single KVM switch only. For information on
cascading multiple KVMs, see Cascade Conguration below.
5. Turn on the 1UCABCONS, followed by the computers.

Instruction Manual

NOTE: After the initial power up, you can hot-plug additional computers or slave KVM
switches without having to power down your KVM.
NOTE: For any “CABxxxx” series KVM Module, the connectors (keyboard and mouse) for
the Local Console port on the rear of the KVM module are not active while the module
is connected to the LCD Console by the C-36 connector. When the C-36 connector is no
longer connected to the LCD Console, the keyboard/mouse ports become active and
the KVM module can act as a rear mounted standalone KVM switch. The Local VGA port
can be connected to an external VGA monitor at any time.
Cascade Conguration
You can connect a second level of KVM switches to one or more of your Master KVM
switch’s PC ports. The KVM switches connected to the Master switch are know as
Slaves. Once connected, the KVM switches will automatically congure themselves as
either Master or Slaves. You can only connect an equal or “smaller” KVM to the Master
KVM. For example, a 16-port Master KVM switch can have both 16-port and 8-port
slaves. An 8-port Master KVM switch can only have 8-port KVM slaves or lower.
The 8-port KVM can support 64 PCs, with 8 8-port Slave KVMs, each connected to 8
PCs. The 16-port KVMs can support 136 computers, with 8 16-port Slave KVMs, each
connected to 16 computers. The Slave KVMs must be connected to the 1~8 ports,
not the A~H ports on the Master KVM.
To cascade your KVMs, use a StarTech.com KVM cable to connect one of your Master
switch’s PC ports to the Slave switch’s Console ports.
A slave KVM module may be mounted to the rear vertical poles inside a rack cabinet by
the rear brackets with the connectors facing out.

Driver Installation
The KVM Module uses generic keyboard/mouse/monitor drivers that are built into the
operating system, so no additional drivers are required.

Operating Your KVM Switch
To toggle between computers, you can use the hot-key commands, OSD (On-Screen Display)
menu or by using the push buttons built into the 1UCABCONS series LCD Rack Console.
Push Buttons
A solid red indicator reects the port selected. The indicator ashes red when in Auto
or Manual Scan mode. You can press any of the corresponding push buttons to select
the active computer. On the 16 port models, Port 1 and Port A share the same push
button, as do Port 2 and Port B, etc. To select Ports 1 through 8, press the push button
once. To select Ports A through H, press and hold the push button for two seconds.
Alternatively, if Port 1 is currently selected and you want to select Port A, you can press
the push button once to switch to Port A.
The K/M Reset function recongures your system without powering down your
computers or your KVM switch. To reset the switch, press and hold the front-panel 1
and 2 buttons simultaneously.
The Auto-Scan function automatically scrolls through your connected computers. Press
and hold the front panel 7 and 8 buttons simultaneously to enter Auto Scan mode.
OSD Operations
A computer may be selected by issuing hot-key commands or by activating the OSD
window. The Auto-Scan function automatically scrolls through your connected computers.
By hitting the left <CTRL> key twice within two seconds, you may see the Hotkey
Menu (if it is enabled as an OSD option). Or, by hitting the left <CTRL> key three times
within two seconds, you will see a KVM MENU screen (below) showing a list of the
computers with corresponding channel addresses, names and status.
The port number of the currently selected computer is displayed in red, at the right
corner of the OSD menu.
The color of a device name is green if it has power and is ready for operation, or the
color is white if it has no power. The OSD menu updates the color when it is activated.

Instruction Manual

Use the up < > and down < > arrow keys to highlight a computer and the <ENTER>
key to select it. Or, you may press <ESC> to exit the OSD and remove the OSD menu
from the display; the status window returns to the display and indicates the currently
selected computer or operating status.
A triangle mark ( ►) to the right of a name indicates the port is cascaded to a Slave;
the number at the left of the triangle mark shows the number of ports the Slave has
(i.e. 8 for an 8-port switch). The <ENTER> key brings you one level down and another
screen pops up listing the names of the computers on that Slave. The name of the
Slave will be shown at the upper right corner of the OSD menu. It is useful to group
computers and still be able to see the group name.
An eye mark (N) to the right of a name indicates the computer is selected to be
monitored in Scan mode. In OSD, this mark can be switched on or o by function key
<F2>. Press the <ESC> key to exit OSD and to return to the selected computer; the
computer name is also shown on the screen.
Editing Computer Name Assignments
Function key <F1> - To edit the name entry of a computer or a Slave, rst use the
< > and < > arrow keys to highlight a port then press <F1> followed by name
entry. Valid characters are‘A’~’Z’, ‘0’~’9’ and the dash (-) character. Lowercase letters
are converted to uppercase ones. Press <BACKSPACE> to delete one letter at a time.

Non-volatile memory stores all name entries until you change, even if the unit is
powered down.
Selecting Computers for Autoscan
Function key <F2> - Use this key to switch the eye mark (N) of a computer on or
o. First, use the < > and < > arrow keys to highlight it, then press <F2> to switch
its eye mark on or o. If Scan Type reads ‘Ready PC + N‘, only the power-on and eye
mark selected computers will be displayed sequentially in Scan mode.
Locking Devices (Slave or computer)
Function key <F3> - To lock a device (a computer or a Slave) from unauthorized
access, use Security. Security is eective for only one device (a computer or a
Slave). To lock a device, use the < > and < > arrow keys to highlight it, then
press <F3>. Now, enter up to 4 characters (‘A’~’Z’, ‘0’~‘9’, ‘-‘) followed by <ENTER>
as new password. A Security enabled device is marked with a lock (Ï)following its
port number. To permanently disable the security function from a locked device,
highlight it, press <F3> then enter the password.
If you want to access the locked device temporarily, simply highlight it and press
<ENTER>. The OSD will prompt for the password. After entering the correct password,
you are allowed to use the device. This device is automatically re-locked once you
switch to another one. During Scan mode, OSD skips the security-enabled device.
Advanced Functions
Function key <F4> - More functions are available by hitting <F4>. A new screen pops
up displaying more functions as described below. Most of them are marked with a
triangle ( ►) indicating there are options to choose from. Using the < > and < >
arrow keys, select the functions and press <ENTER>. Available options will be shown in
the middle of the screen. Again, using the < > and < > arrow keys to view options,
then press <ENTER> to select it. You can press <ESC> to exit at any time.
Auto Scan
In this mode, the Console automatically switches from one powered computer to
the next, sequentially in a xed interval. During Auto Scan mode, the OSD displays
the name of the selected computer. When Auto Scan detects any keyboard or
mouse activity, it suspends the scanning until activity stops; it then resumes with
the next computer in sequence. To abort Auto Scan mode, press the left <CTRL>
twice, or, press any front button. Scan Type and Scan Rate set the scan pattern. Scan
Type (<F4>:More\Scan Type) determines if scanned computers must also be eye
mark selected. Scan Rate (<F4>:More\Scan Rate) sets the display interval when a
computer is selected before selecting the next one.

(<F4>:More\Scan Type) determines if scanned computers must also be eye mark
selected. Press the up arrow < > key to select the previous computer and the
down arrow < > key to select the next computer. Press any other key to abort
Manual Scan mode.
Audio Stick
An optional multimedia module can be linked to the back of each KVM Module for
selecting microphone and stereo speaker signals. There are two options for Audio
Stick: On and O. When set to On, audio selection follows computer selection. When
set to O, audio selection stops following computer selection. It is useful if you want
to listen to a particular computer’s audio signal while operating other computers.
The non-volatile memory stores the Audio Stick setting.
Scan Type
Ready PC + N:In Scan mode, scan through power-on and eye mark selected
computers. Ready PC: In Scan mode, scan through power-on computers.
Nonly: In Scan mode, scans through any selected computer regardless of
computer power status with an eye mark.
The non-volatile memory stores the Scan Type setting.
