example, printers, external hard drives, and so on).
2. Connect a monitor to the Console DisplayPort port on the KVM switch.
3. Connect a USB keyboard and mouse to the Console USB keyboard and mouse
ports on the KVM switch.
4. If necessary, connect speakers or a headset to the Console audio port on the KVM
switch.
Connect computers to the KVM switch
You can connect up to four computers to the KVM switch.
1. Turn o the computers that you want to connect to the KVM switch and any devices
or peripherals that are connected to the computers (for example, printers, external
hard drives, and so on).
2. Connect a male-to-male DisplayPort cable to the computer’s DisplayPort port and
to one of the numbered PC connection ports on the KVM switch.
3. Connect a USB A to B cable to the computer’s USB port and to the same numbered
PC USB port on the KVM switch that you connected the DisplayPort cable to in
step 2.
4. If you’re using audio, connect a set of audio cables to the speaker port on your
computer and to the same numbered PC audio port on the KVM switch that you
connected the DisplayPort cable to in step 2.

You should now be able to switch between the connected computers or devices. If
you’re experiencing issues with this KVM switch, see the “Troubleshooting” topic.
About drivers
You don’t need to install any drivers for this KVM switch, as the keyboard and mouse
use generic USB drivers that are already installed on any operating system that
supports USB technology.
Troubleshooting
If you experience issues using this KVM switch and you’re using a PC, you might want
to make the following changes to the BIOS settings on your computer:
1. Set HALT ON ERROR to All but keyboard.
2. In PNP AND PCI SETUP, do the following:
• Set PNP OS INSTALLED to YES.
• Set USB IRQ to ENABLED.
About video adapters
If you use a video adapter with this KVM switch, you must use an active video adapter.
If you use a passive video adapter, you might encounter performance issues.
Check with the manufacturer to determine if the video adapter that you want to use is
an active adapter.

dierent port.
Start AutoScan
When you start the AutoScan feature, the system automatically scans through the
computers that are turned on and connected to the KVM switch in sequence for a xed
interval of time.
If any keyboard or mouse activity is detected during the AutoScan, the scanning is
suspended until the activity stops. AutoScan then resumes with the next computer in
the sequence.
• To start AutoScan, press Port selection button 3 and Port selection button 4
simultaneously.
• To end AutoScan, press any of the numbered Port selection buttons on the front of
the KVM switch.

Change the AutoScan interval time
You can set the AutoScan interval time to one of four options: 3, 8, 15, or 30 seconds.
By default, the AutoScan interval time is set to 3 seconds after a blackout or restart.
When you set the AutoScan interval time, the KVM switch beeps a specic number of
times to indicate the duration of time that you’re setting:
Number of beeps Corresponding AutoScan interval
1 3 seconds
2 8 seconds
3 15 seconds
4 30 seconds
• To change the AutoScan interval time, press and hold Port selection button 1 and
Port selection button 2 simultaneously until you hear the number of beeps that
corresponds to the duration of time that you want to set.
About the virtual USB HID function
The virtual USB HID function can simulate the USB Human Input Device (for example,
keyboard or mouse) on all of the computers connected to the KVM switch. This can
save you time when you switch ports.
• To use this function, do one of the following:
• Connect the USB device to the Console USB keyboard and mouse port on the
front of the KVM switch.
• Connect the USB device to any of the three Console USB keyboard and
mouse ports on the back of the switch.
