Installation
NOTE: Prior to the installation, please power o all devices that will be connected to
this system.
Ensure that all devices you will connect are properly grounded.
Place cables away from uorescent lights, air conditioners, and machines that are likely
to generate electrical noise.
Console Installation
The SV831DUSB and SV1631DUSB are designed to use both USB and PS/2 console
connections, and are equipped with a slide switch console selector for the selection of
USB or PS/2 modes. There are three connection patterns that correspond with the slide
switch as follows:
PS/2 Keyboard and PS/2 Mouse: A PS/2“Y” cable (provided) is required for this mode.

PS/2 mouse and keyboard
PS/2 Keyboard and USB Mouse: Slide switch to the center position
Slide Switch selection:

Slide Switch selection:
USB keyboard and USB mouse
NOTE: When conguring the switch as a Slave in a cascaded conguration, PS/2
Keyboard and Mouse is the only mode that can be used. Therefore, SV431DUSB
cannot be congured as a slave in a cascaded setup, as it does not provide a slide
switch selector.
NOTE: When using a combination Keyboard and Mouse use the USB Keyboard Port
for product revision 1 - 4. For product revision 5 and up use the USB Mouse Port to
connect the device.
Computer Installation
USB Computer
To connect a computer controlled through USB, use a StarTech.com 2-in-1 Ultra-
Thin USB KVM cable (Product ID: SVECONUS) to connect from one of the PC Ports
located on the rear panel of the KVM switch to the USB and VGA ports on the
computer system.

PS/2 Computer
To connect a computer controlled through PS/2, use a StarTech.com 3-in-1 Ultra-Thin
PS/2 KVM cable (Product ID: SVECON) to connect from one of the PC ports to the PS/2
keyboard and mouse, as well as the VGA port of the computer system.
Cascaded congurations
NOTE: The master must have equal or more PC ports than that of the slave. 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.
NOTE: PS/2-only models can be cascaded with USB+PS/2 universal models.
NOTE: To be used as Slaves in a cascaded conguration, the slide switch on
SV831DUSB or SV1631DUSB must be adjusted to PS/2 mode.
The ports labelled PC 1 - PC 8 can be connected to either a computer or a Slave’s
CONSOLE port. The ports marked PC A - PC H can only be connected to computers. Use
only the 3-in-1 (PS/2) cables to connect the Master’s PC ports and Slave’s CONSOLE port.

The maximum number of computers controlled by a Master/Slave conguration with
all 8-port units is 64, with 8 Slaves and each Slave connecting to 8 computers:
The maximum number of computers controlled in a Master/Slave conguration with
all 16-port units 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.
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 reect the computer port selected (red) and whether the port is connected
to a powered computer (green). The indicator ashes 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 push button, 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
push button once to select Port A. If Port 1 is not selected, press and hold push button
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 conguration changes. Press down buttons 1 and 2 simultaneously for 2
seconds to recongure the whole system without having to turn o 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).

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.
