Introduction
The StarTech.com SV231UAF allows a single USB keyboard, mouse and
monitor to be switched to access up to two computers. The device offers
a compact design saving desk space, in addition to saving the cost of
purchasing separate peripherals for each computer. The Picture-in-Picture
function allows you to look at the other connected system while still working
on the one in focus, while the data link feature lets you perform a simple
drag and drop data transfer between the two computers. Backed by a
StarTech.com 1-year warranty and free lifetime technical support.

How to Use
Hotkey Switching
A Hotkey command is a short keyboard sequence for selecting a computer
connected to the KVM switch. A hotkey sequence consists of two
keystrokes (successively within 0.2 seconds). A built-in tone generator
creates a high-pitched beep for a correct hotkey command.
To switch from the currently selected computer to the next computer,
including audio:
[Scroll Lk] + [Scroll Lk]
To switch from the currently selected computer to the next computer, but
not switch the audio:
[Caps Lk] + [Caps Lk]
KMDS Software
The KMDS icon in the System Tray is used to access various additional
features by right-clicking the icon.
Switch KVM
Switch computer control, video and audio to the next computer.
Switch Audio
Switch only audio to the next computer, while control and video remain
on the current computer.
KVM PIP
Activate the Picture-In-Picture window to view a scaled-down video feed
of the next computer system. The primary purpose is for performing a

Software Notes
• File transfers and text copy/paste operations through the KMDS
software, should only be performed if both computer operating systems
are set to the same language version.
• File transfers are only supported to the Windows Desktop. Identical
file names on the desktop will be automatically overwritten without
notification. Caution is recommended when transferring files.
• Picture in Picture mode (PIP) is not suitable for watching multimedia
files.
• Do not change the computer screen resolution while PIP mode is active.
• Do not unplug the KVM cables or attempt port switching while a file
transfer is in progress. Exit the KMDS software before disconnecting the
KVM from a running computer system.
• While using the KMDS software, it is recommended that users have full
Administrator access.
• If any errors are encountered during use of the KMDS software, exit the
software and reconnect the USB and VGA connectors and restart the
KMDS software.
Troubleshooting
Problem: Unable to set proper video resolution for the connected display.
Solutions:
• This KVM switch will store the EDID information from the last
connected display, so if replaced with a non-EDID compliant display,
the connected computers will still receive the EDID from the previous
display. This may prevent you from selecting the proper video
resolution for the new display. An EDID compliant display needs to be
connected to the KVM switch to override the stored EDID information.
• Check the VGA cable connection between the KVM switch and the
VGA display and/or replace cable (with shorter cable, if applicable).
