Chapter 3: Installation
3. Installation
Before installation, power off all devices that will be connected to this system.
• Make sure 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.
3.1 PC BIOS Notice
The following BIOS setup changes are necessary for PC users and not necessary
for Mac users:
• In standard CMOS, set “Halt on Error” to “All but keyboard.”
• In PNP and PCI setup, set “PNP OS installed” to “YES” and set “USB IRQ” to
“Enabled.”
NOTE: The ServSwitch DT Dual-Head DVI USB, 8-Port switches USB keyboard and
USB mouse from one computer to the other. If you plan to share other
peripherals such as a camera, printer, external storage device, or scanner,
shut down a computer’s driver before switching to another computer.
Port switching is equivalent to unplugging the USB cable from one
computer and plugging it into another. Some USB drivers check attached
USB peripherals constantly and do not support plug-n-play functionality.
3.2 Device Connection
3.2.1 Console Connection
1. Plug the monitors into the console’s video port; plug a USB keyboard and a
USB mouse into the corresponding USB ports on the console.
2. To use the standard audio feature, plug a set of audio jacks from the speaker
and microphone to the console’s speaker port and microphone port
respectively,
3. Plug USB peripherals into the USB 1 and/or USB 2 ports on the console side if
needed.

Auto Scan: In this mode, the KVM switch automatically switches from one
powered-on computer to the next sequentially in a fixed interval. During auto
scan mode, the OSD displays the name of the selected computer. When Auto
Scan detects any keyboard or mouse activity, it suspends the scanning until
activity stops. Then, it resumes scanning with the next computer in sequence. To
abort the autoscan mode, press the Left-Ctrl button twice, or press any front-
panel button. Scan type and scan rate set the scan pattern. Scan Type (F4: More\
Scan Type) determines if scanned computers must also be eye-mark selected.
Scan Rate (F4: More\Scan Rate) sets the display interval when a computer is
selected before selecting the next one.
Manual Scan enables users to manually switch back and forth between active
computers via keyboard control. Type F4: (More\Scan type) to determine if
scanned computers must also be eye-mark selected. Press the up-arrow key to

If no new EDID information is available from a display, a default profile in the
KVM switch is automatically provided instead.
The system can get EDID details from the monitor by using the following
methods:
• Copy DVI: Under the DVI (DVI1) monitor connection, users can copy the DVI
monitor’s EDID data as the system video display setting.
• Copy VGA: Under the VGA monitor connection, users can copy the VGA
monitor’s EDID data as the system video display setting.
• Sequence Hunting: The system will automatically search any available EDID data
from the connected display or embedded EEPROM (Read-Only memory)
• Default: The display configuration will follow the factory default setting.
NOTE: When users plug both the DVI and VGA monitor into the video ports on
the switch, the DVI (DVI1) EDID data has the priority over the VGA EDID
data.
NOTE: The system will automatically Copy the DVI EDID data as the system video
display setting when it detects the DVI (DVI1) monitor connection.
Esc: To exit the OSD, press the Esc key.
