Console Connection
The SVxxxDUSBUx series of KVM switches are designed to use USB console connections only. A USB compatible keyboard and mouse and VGA monitor must be used for the local console. A USB keyboard/ mouse combo device that uses a single USB connector may also be used, but must be connected to the USB Keyboard port. StarTech SV431DUSBU 4 Port 1U Rackmount USB KVM Switch with
OSD-1

Connecting Computer to the KVM Switch
To connect a computer to the KVM switch, use the appropriate StarTech.com KVM cable to connect from one of the PC ports located on the rear panel of the KVM switch to the keyboard/mouse and VGA video ports on the computer StarTech SV431DUSBU 4 Port 1U Rackmount USB
KVM Switch with OSD-2

Cascaded configurations
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. StarTech SV431DUSBU 4
Port 1U Rackmount USB KVM Switch with OSD-3

The maximum number of computers controlled by a Master/Slave configuration 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 configuration 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. StarTech SV431DUSBU 4 Port 1U
Rackmount USB KVM Switch with OSD-4

NOTE! A device (computer or KVM switch) at any ‘PC x’ port can be changed at any time after initial power-up.

StarTech SV431DUSBU 4 Port
1U Rackmount USB KVM Switch with OSD-6

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 Sunmarked port has not been selected if you are already using a Sun keyboard.
With different 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 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.
The short form hotkey menu can be turned on as an OSD function (:More\Hotkey Menu) every time the left is pressed twice.
NOTE: Left : 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 first 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 , Left , 7 : Selects a computer connected to port 7 of the Master.
Left , Left 6, C : Selects a computer connected to port C of a Slave connected to port 6 of the Master.
