Installation
NOTE: Prior to the installation, please power off all devices that will be
connected to this system.
Ensure that all devices you will connect are properly grounded.
Place cables away from fluorescent 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 Keyboard and USB Mouse: Slide switch to the center position
Slide Switch selection:
PS/2 mouse and
keyboard
Slide Switch selection:
PS/2 keyboard and
USB mouse

3
USB Keyboard and USB Mouse: Slide switch to the far right position.
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. Therefore, SV431DUSB cannot be configured as a slave in a
cascaded setup, as it does not provide a slide switch selector.
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 configuration, 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
configuration 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
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.
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

6
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

Country Code for Sun:
Sun keyboards of different languages have different layouts. The KVM
switch is able to emulate a Sun keyboard for a specific language type
or country such as Arabic, Belgian, US, Yugoslavia, etc. Select the
proper country code that matches all of your Sun computers.
NOTE: The country code must be set prior to powering up the Sun
computer. Not performing this step prior to power-up could cause the
system to malfunction.
Max. Resolution:
It supports widescreen, and you can adjust the monitor resolution
under this sub-menu. The following selections are available: 1024 x
768, 1280 x 1024, 1600 x 1200, 1920 x 1440 and “DDC2B Disable”.
To switch the Sun mark of a port on or off indicatingFunction Key <F5>:
the computer is a Sun server as shown in Figure
12. Sun servers have more keys on the keyboard
than a PC. When a Sun-marked port is selected,
the KVM Switch starts to translate the keys from a
PC keyboard to a Sun keyboard. See the section

12
entitled Sun Keyboard Mapping for further detail.
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 Sun-marked 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 <ESCAPE> 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
(<F4>:More\Hotkey Menu) every time the left <CTRL> is pressed twice.
NOTE: Left <CTRL>: refers to the Control key on the left side of the
keyboard.
refers to the number keys ‘1’~’8’ in the upper row of the1~8/A~H:
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

13
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 <CTRL> , Left <CTRL>, <7> : Selects a computer connected to
port 7 of the Master.
Left <CTRL> , Left <CTRL>, <6>, <C> : Selects a computer
connected to port C of a Slave connected to port 6 of the Master.
Auto Scan
In this mode, the KVM Switch automatically switches from one
power-on computer to the next, sequentially, in a fixed interval. During
AutoScan mode, the OSD displays the name of the selected computer.
Left <CTRL>, Left <CTRL>, <F1>
When Auto Scan detects any keyboard or mouse activity, it suspends
the scanning until the activity stops. It then resumes with the next
computer in sequence. The length of the Auto Scan interval (Scan
Rate) is adjustable. To abort Auto Scan mode, press the left <CTRL>
key twice.
NOTE: Scan Type determines whether an eye-marked computer is to
be displayed during Auto Scan.
Manual Scan enables you to manually switch back and forth between
the powered computers:
Left <CTRL>, Left <CTRL>, <F2>
Press the <UP> arrow key to select the previous computer and the
<DOWN> arrow key to select the next computer. Press any other key to
abort Manual Scan mode.
NOTE: Scan Type determines whether an eye-marked computer is to
be displayed during Auto Scan.
To adjust Scan Rate, which sets the duration before switching to the
next computer in Auto Scan:
Left <CTRL>, Left <CTRL>, <F3>

14
The switch will beep one to four times indicating the scan interval of 3,
8, 15 and 30 seconds respectively.
To adjust keyboard typematic rate (characters/sec) for PS/2 keyboards:
Left <CTRL>, Left <CTRL>, <F4>
The KVM switch beeps 1 to 4 times corresponding to 10, 15, 20 and 30
characters/sec respectively.
Sun/Mac Keyboard Mapping
The KVM Switch emulates a Sun Keyboard when a computer is
marked with a Sun, in the OSD menu by Function Key <F5>. A Sun
keyboard has more keys than a standard PC keyboard. These extra
keys are simulated by tapping the Right <CTRL> button, which is
normally located on the right lower part of the keyboard, followed by
one of the function keys on the general keyboard (i.e. combo key). For
example, tap the Right <CTRL> key, and then tap the function key
<F7> to activate Open for a Sun computer.
NOTE: For older Sun Operating Systems, the switch does not support
the LowPower option under Power Off Select.
For keystroke emulation of Sun/Mac computers, please refer to the
above chart and conduct the following two examples:
“Stop A” function in Sun: Press right <CTRL> and release, then within
two seconds press <F1> and <A> in sequence.
