Installation
Warning: Prior to installation, please ensure that all computers and
KVM switch(es) are powered down.
Device Connection
The SV831DUSB is designed for use with both USB and PS/2 console
connections, and is equipped with two slide switch console selectors
used for the selection of USB or PS/2 modes for the mouse and keyboard
(shown below).
There are three connection patterns that correspond with the slide switch
as follows:
PS/2 Keyboard and PS/2 Mouse:1. A PS/2 Y-connector (provided) will
be required for this connection to allow both the mouse and keyboard
to be connected to the PS/2 port. The mouse and keyboard slide
switches must be switched to the left.

Mouse
USB
PS/2

PS/2 Keyboard and USB Mouse:2. The mouse slide switch must be
switched to the right, while the keyboard slide switch must be switched
to the left.
USB Keyboard and USB Mouse:3. Both the keyboard and mouse
switches must be switched to the right.
Please note: When configuring the switch as a slave in a cascaded
configuration, PS/2 Keyboard and Mouse is the only mode
that can be used. As such, SV431DUSB cannot be
configured as a slave in a cascaded setup, as it does not
provide a slide switch selector.

Connecting Computers to the Console
USB Only
To connect a computer controlled by USB peripherals, use a 1-to-2 cable
(SVECONUSx) to connect from one of the PC Ports located on the rear
panel of the KVM switch to the USB and Video ports on the computer, as
shown below.
PS/2 Only
To connect a computer controlled by PS/2 peripherals, use a 1-to-3 cable
(SVECONx) to connect from one of the PC ports to the PS/2 keyboard
and mouse, as well as the video port of the computer.

Cascaded Congurations
Please note: The master KVM Switch must have equal or more PC x
ports than that of the slave kvm unit. 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.
Please note: PS/2-only models can be cascaded with USB+PS/2 univer-
sal models.
Please note: To be used as slaves in a cascaded configuration, the slide
switch on SV831DUSBA must be adjusted to PS/2 mode.
The ports labelled PC 1 - PC 8 can be connected to either a computer
or a slave unit CONSOLE port, as shown below. Use only 1-to-3 (PS/2)
cables to connect the master’s PC ports and slave CONSOLE port, as
shown below.

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 mod-
els, 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 but-
tons 1 and 2 simultaneously for 2 seconds to reconfigure the whole sys-
tem 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. (SV431DUSB uses buttons 3 and 4 to launch this function).
