1. Introduction
Thank you for purchasing LevelOne KVM-0831/1631 Combo KVM Switch. The KVM
Switches offer the most reliable and efficient way of managing multiple computers in server
rooms where space is at a premium. On Screen Display (OSD) features computer naming,
computer selection, status indication, auto scan and much more. Up to 128 servers can be
easily managed by cascading multiple KVM switches to expand the capacity.
Revolutionized video enhancement technology ensures superb quality up to 1920 x 1440.
KVM-0831/1631 supports host PC with PS/2 and USB interface. The convenient HDDB-15
to VGA+PS/2+USB cable allows user to connect to different kinds of PC interfaces by the
same cable. Users no longer need to prepare two kinds of cables for their PCs or servers
with different kinds of interfaces. Users can save their time and cost when building their
system.
Besides the USB console port, KVM-0831/1631 support an optional module which provide
Cat.5 remote console for users to access KVM switch remotely with the KVM-9007 Cat.5
Receiver. After making connection between KVM switch and Cat.5 receiver by Cat.5/5e/6
cable, users can control their system remotely and the distance can be up to 300 meters.
Users can use their existing LAN cables to do the remote control, this also saves their cost
and reduce the complexity. Some server room environments are too noisy for people or
unsuitable to work there for a long time, this remote control feature is an ideal solution for
these situations.

NOTE:
1. Local console and Remote console of the KVM switch have the same priority to control computers
connected to the KVM switch. The display output is the same at the local and remote console
monitors. The priority mechanism is: the first move port has the priority and will release the priority if
it did not keep input for 2 seconds.
2. If the video signal is foggy or un-cleared on the screen, please check if the VGAconnector
3. For the best display result, it is highly recommended to use Cat.6 cable when the connection distance
is longer than 150 meters.
Step 5 PC Port Connection
The PC port connector is HDDB-15 pin type. Plug the HDDB-15 end of the KVM cable
(HDDB-15 to VGA+PS/2+USB type) into PC port on the rear of KVM switch unit.
(ACC-2101/ACC-2102/ACC-2103).
(a) For PS/2 computers - Plug the PS/2 connector into the PS/2 mouse port of PC. And to
use the USB to PS2 adaptor to convert the USB connector into PS/2 interface, then
connect it to the keyboard port of PC.
The Rear Side of PC
(b) For USB computers - Plug the USB connector into the USB port of PC and no need to
connect the PS/2 connector to the PC.
Step 6 Double Check
Double-check all of the connections. You can check the color of keyboard and mouse
connector to make sure the keyboard and mouse connectors are plugged to the correct
ports.
Step 7 Power On
Attach the power supply to the KVM unit and plug the other end into a receptacle. The Port
1 LED will be lit up, and you will hear a beep. Please switch on your monitor.
Note: Please remember to plug the power adapter. Although the PCs connected to KVM
Switch are able to support enough power to the stand alone switch, KVM switch still needs
a power adapter for daisy chain more banks. Unexpected status may occur If you try to
daisy chain more KVM switches without plugging the power adapter.
