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 Conguration below.
5. Turn on the 1UCABCONS, followed by the computers.
Instruction Manual
3
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 Conguration
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 congure 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.
KVM cables
* 16-port model shown
Driver Installation
The KVM Module uses generic keyboard/mouse/monitor drivers that are built into the
operating system, so no additional drivers are required.

NOTE: It is unnecessary to switch the Sun mark ON or OFF if an authentic Sun
keyboard is being used on the console. In other words, you must ensure that the Sun-
marked port has not been selected if you are already using a Sun keyboard.
With dierent types of keyboard and computer, the Sun Mark must be set up in
compliance with the following instruction:
Keyboard Type Computer Type Sun Mark
USB (non-Sun) PC/Mac No
USB (non-Sun) Sun Yes
USB (Sun keyboard) PC/Mac No
USB (Sun keyboard) Sun Yes
ESC: To exit the OSD, press the <ESCAPE> key
Hot-key commands
A Hot-key command is a short keyboard sequence used to select a computer, to
activate computer scan, etc. The Console constantly interprets keystrokes for hot-keys.
A hot-key sequence starts with two left <CTRL> keystrokes followed by one or two
more keystrokes. A built-in alarm generates a high-pitch beep for correct hot-key
command; otherwise, one low-pitch beep for error and the bad key sequence will not
be forwarded to the selected computer.
The short form hot-key menu can be turned on as an OSD function (<F4>: more\
Hotkey Menu) every time the left <CTRL> key is pressed twice.
CTRL: is the <CTRL> key located at the left side of the keyboard.
1~8/A~H: are the number keys ‘1’ ~ ‘8’ at the upper row of the keyboard and character
keys ‘A’ ~ ‘H’ case insensitive. Do not use the keypad at the right of the keyboard.
To select a computer by hot-key command, you must know its port number, which is
determined by the KVM Module connection. For a computer connected to a Master,
its port is represented by the PC port label (1~8 or A~H). For a computer connected to
a Slave, two characters represent its port. The rst character is the port number of the
Master unit (1~8) and the second one is the port number of the Slave (1~8 or A~H).
Please note that only Master’s ‘PC 1’ ~’PC 8’ ports can be connected to a Slave.
Left <CTRL> + left <CTRL> + <7>
Selects a computer connected to port 7 of the Master.
Instruction Manual
10
Left <CTRL> + left <CTRL> + <6> + <C>
Selects a computer connected to port C of a Slave connected to port 6 of the Master.
Auto Scan, automatically scans power-on computers one by one at a xed interval:
Left <CTRL> + left <CTRL> + <F1>
When Auto Scan detects any keyboard or mouse activity, it suspends the scanning
till activity stops; it then resumes with the next computer in sequence. The length of
the Auto Scan interval (Scan Rate) is adjustable, see below. To abort the Auto Scan
mode, press the left <CTRL> key twice.
NOTE: Scan Type determines whether an eye-marked computer is to be displayed
during Auto Scan.
Manual Scan enables you to manually switch back and forth between power-on computers.
Left <CTRL> + left <CTRL> + <F2>
Press < > or < > to select the previous or the next computer in sequence. Press
any other key to abort the Manual Scan.
NOTE: Scan Type determines whether an eye-marked computer is to be displayed
during Auto Scan.
To adjust Scan Rate which sets the duration before switching to the next computer in
Auto Scan:
Left <CTRL> + left <CTRL> + <F3>
The Rack Console sends one to four beeps indicating scan interval of 3, 8, 15 and 30
seconds respectively.
To adjust keyboard Typematic Rate (characters/sec), this setting over-rides that of
BIOS and any operating system:
Left <CTRL> + left <CTRL> + <F4>
The Rack Console will generate 1 to 4 beeps corresponding to 10, 15, 20 and 30
characters/sec respectively.
Change Leading Hotkey
The default leading hotkey sequence involves pressing the left <CTRL> twice in
succession (e.g. left <CTRL>, left <CTRL>). This can be changed to the right <CTRL>
key instead, to avoid accidental activation due to using the left <CTRL> key for
functions such as Copy/Paste.
Instruction Manual
11
To change the leading hotkey sequence to Right <CTRL>:
Left <CTRL>, Left <CTRL>, hold <ALT>, press Right <CTRL>
All hotkey commands that previously required pressing the Left <CTRL> will be
switched to requiring the right <CTRL> instead.
To change the leading hotkey sequence back to Left <CTRL>:
Right <CTRL>, Right <CTRL>, hold <ALT>, press Left <CTRL>
Sun/Mac Keyboard Mapping
The KVM Switch emulates a Sun Keyboard when a computer is marked with a Sun, in
the OSD menu by Function Key <F5>. A Sun keyboard has more keys than a standard
PC keyboard. These extra keys are simulated by tapping the Right <CTRL> button,
which is normally located on the right lower part of the keyboard, followed by one of
the function keys on the general keyboard (i.e. combo key). For example, tap the Right
<CTRL> key, and then tap the function key F7 to activate Open for a Sun computer.
NOTE: For older Sun Operating Systems, the switch does not support the LowPower
option under Power O Select.
For keystroke emulation of Sun/Mac computers, please refer to the chart below and
conduct the following two examples:
Stop A function in Sun: Press right <CTRL> and release, then within two seconds press
F1 and A in sequence.
