Installation

Hardware Installation

WARNING: Prior to installation, please ensure that all computers and

KVM switch(es) are powered down.

Console Connection

The SVxxxDUSBU 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.

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.

Cascaded congurations

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

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.

KVM cables

*SV1631DUSBU shown

NOTE: A device (computer or KVM switch) at any ‘PC x’ port can be

changed at any time after initial power-up. If you change any one of the

PC 1 to PC 8 port connections from a computer to a Slave KVM switch

or vice versa, or replace the devices of a port, the OSD will update this

change the next time it is activated.

Operation

You may select a computer by pressing the front panel push button

directly, by issuing hot-key commands or by activating the OSD

window. The front panel indicator changes to reﬂect the computer

port selected (red) and whether the port is connected to a powered

computer (green). The indicator ﬂashes red when it is in either Auto

Scan or Manual Scan mode.

Push Button controls

To select control of an attached computer, press the front panel button

that corresponds with the assigned computer number. For 16 port

models, 1 to 8 represents the lower 8 ports, while A to H indicates the

higher ports. Ports 1 and A share the same pushbutton, as do 2 and B,

3 and C, etc.

EXAMPLE: If port 1 is already selected and you wish to switch to Port

A, tap the shared pushbutton once to select Port A. If Port 1 is not

selected, press and hold pushbutton 1 for two seconds to select Port A.

K/M Reset

K/M Reset resolves the majority of problems developed by keyboard

and/or mouse device replacement or conﬁguration changes. Press

down buttons 1 and 2 simultaneously for 2 seconds to reconﬁgure

the whole system without having to turn off the KVM switch or any

attached computers.

Auto Scan

This KVM switch provides an easy to use feature to start Auto

Scanning. To use this function, simultaneously press buttons 7 and

8 and hold for two seconds. (SV431DUSBU uses buttons 3 and 4 to

launch this function).

OSD (On Screen Display) Operation

By hitting the left <CTRL> key twice within two seconds, you may see

the ’Hotkey Menu’ if it is enabled (an OSD option). Or, by hitting the

left <CTRL> key three times within two seconds, you will see a ’KVM

MENU’ screen showing a list of the computers with corresponding

channel addresses, names and status.

The channel address (port number) of the currently selected computer

is displayed in red, same as the front indicator, to the right of the OSD

title ’KVM MENU’.

The color of a device name is green if it has power and is ready for

selection (its corresponding front panel indicator is green). The color is

white if it has no power. The OSD menu updates when it is activated.

Use the <UP> and <DOWN> arrow keys to highlight a computer and

the <ENTER> key to select it. Or, you may press <ESCAPE> to exit

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 SV831DUSBU. 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 off by function key <F2>.

Press the <ESCAPE> key to exit the OSD and to return to the selected

computer, The computer name is also shown on the screen.

Function key <F1>: To edit the name entry of a computer or a Slave.

First, use the <UP> and <DOWN> arrow keys to

highlight a channel 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 the <BACKSPACE> key

to delete a letter one at a time. Nonvolatile memory

stores all name entries until you change, even if the

unit is powered down.

Function key <F2>: To switch the eye mark (N) of a computer on or off.

First, use the <UP> and <DOWN> arrow keys to

highlight it, then press <F2> to switch its eye mark

on or off. If Scan Type is ’Ready PC + N’, only the

power-on and eye mark selected computers will be

displayed sequentially in Scan mode.
