Cascaded congurations
NOTE: The Master KVM switch must have equal or more PC ports than that of the Slave
KVM switches. For example, if an 8-port switch is the Master, an 8-port or 4-port switch
can be a Slave, but not a 16-port switch.
The ports labelled PC 1 - PC 8 can be connected to either a computer or a Slave KVM
switch’s CONSOLE port. On a 16-port KVM switch, the ports marked PC A - PC H can
only be connected to computers. Use only the appropriate StarTech.com KVM cables
to connect the Master KVM switch’s PC ports and Slave KVM switch’s CONSOLE port:
The maximum number of computers controlled by a Master/Slave conguration
with all 8-port KVM switches used is 64, with 8 Slaves and each Slave connecting to 8
computers:
The maximum number of computers controlled in a Master/Slave conguration with
all 16-port KVM switches used is 136, with 8 units of 16-port Slaves (to PC 1 - PC 8) and
each Slave connected to 16 computers, plus 8 more computers connected directly to
the Master (to ports PC A - PC H):
After the connection has been completed, please re-activate the OSD menu to verify
that the Master recognizes the Slaves. A triangle mark ( ) is placed next to the right
of the channel name indicating that the port is connected to a Slave, not a computer.
A number to the left of the triangle mark indicates the Slave model, i.e. ‘8’ for an 8-port
switch.

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
Hot-key command is a short keyboard sequence used to select a computer, to
activate computer scan, etc. StarView interprets keystrokes followed by one or two
more keystrokes. A built-in buzzer generates a high-pitch beep for a correct hotkey
command, otherwise, one low-pitch beep for an error and the bad key sequence will
not be forwarded to the selected computer.
Instruction Manual
12
The short form hotkey menu can be turned on as an OSD function (<F4>:More\Hotkey
Menu) every time the left <CTRL> is pressed twice.
NOTE: Left <CTRL>: refers to the Control key on the left side of the keyboard.
1~8/A~H: refers to the number keys ‘1’~’8’ in the upper row of the keyboard and
character keys ‘A’ ~ ‘H’. Do not use the keypad at the right of the keyboard.
To select a computer by hotkey command, you must know its port number, which is
determined by the KVM Switch connection. 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 the Master’s ‘PC1’ ~ ‘PC8’ ports can be connected to a Slave.
EXAMPLES:
Left <CTRL> , Left <CTRL>, 7 : Selects a computer connected to port 7 of the Master.
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
In this mode, the KVM Switch automatically switches from one power-on computer to
the next, sequentially, in a xed interval. During AutoScan mode, the OSD displays the
name of the selected computer.
Left <CTRL>, Left <CTRL>, F1
When Auto Scan detects any keyboard or mouse activity, it suspends the scanning
until the activity stops. It then resumes with the next computer in sequence. The
length of the Auto Scan interval (Scan Rate) is adjustable. To abort 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.

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 above chart 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.
