Warning:Prior to installation, please ensure that all computers and KVM switch(es) are powered
down.
Device Connection
SV831DUSB and SV1631DUSB are designed to use both USB and PS/2 console connections, and
are equipped with a slide switch console selector used for the selection of USB or PS/2 modes.
There are three connection patterns that correspond with the slide switch as follows:
1. PS/2 Keyboard and PS/2 Mouse: A PS/2 Y-connector (provided) will be required for this
connection, as illustrated in Fig. 1-1.
2. PS/2 Keyboard and USB Mouse: Slide switch set to the center position as depicted in Fig. 1-2

3. USB Keyboard and USB Mouse: Slide switch set to the far right position as depicted in Fig. 1-3
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.
Single KVM switch configuration - 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 indicated in Fig. 1-4.

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 configurations
Please note: The master must have equal or more PC x 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.
Please note: PS/2-only models can be cascaded with USB+PS/2 universal models.
Please note: To be used as Slaves in a cascaded configuration, the slide switch on
SV831DUSB or SV1631DUSB must be adjusted to PS/2 mode. Please refer to Figure
1-1.
The ports labelled PC 1 - PC 8 can be connected to either a computer or a Slave’s
CONSOLE port, as shown in Figure 1-6. The ports marked PC A - PC H can only be
connected to computers. Use only 1-to-3 (PS/2) cables to connect the Master’s PC ports
and Slave CONSOLE port, as shown in Figure 1-6:
Figure 1-6
Master
Slave

The maximum number of computers controlled by a Master/Slave configuration with all 8-
port units is 64, with 8 Slaves and each Slave connecting to 8 computers (as depicted in
Figure 1-7:
The maximum number of computers controlled in a Master/Slave configuration 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.

Please 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.

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, 1to 8represents the lower 8
ports, while Ato Hindicates the higher ports. Ports 1and Ashare the same pushbutton,
as do 2and B, 3and Cetc.
Example: If port 1is already selected and you wish to switch to Port A, tap the shared
pushbutton once to select Port A. If Port 1is 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 1and 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 7and 8and hold for two seconds. (SV431DUSB
uses buttons 3and 4to 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, see Figure 1-9.
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),or the color is white as it has no power.
OSD menu updates the color 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
