Safety Operation Guide:

1.0 Safety Operation Guide

**************************************************************************
In order to ensure the credibility and the user’s safety, please comply with the following
items during installation, maintenance and operation of the switch.

1) The switch must be in stable position. Use only the power supply that
comes with unit. Do not use an alternate as it may damage it.

2) Do not place the switcher near hot or cold surfaces or sources.

3) To avoid any damage by over heating, please keep the environment in good
ventilation to radiate the heat when running the switcher.

4) The switcher should be turned off when it is not used.

5) Please do not attempt to take cover off the switcher for there is a high-volt
age component inside that could cause electric shock.

6) Do not splash any liquid or chemical on or near the equipment.

7) Please make sure all the wiring are in working condition and are not cut or
damaged.

1.1 About the DVI Matrix Switch

DVI series Matrix switcher is a high-performance professional computer and audio signal
switcher that can be used for cross switching of multi computer and audio signals. Inde­pendent DVI component and balance/unbalance I/O terminals make each component sig­nal transmit and switch separately; this design can reduce signal transmission to minimum
and output the image and audio signal in high-fidelity quality.

DVI series switcher mostly apply in broadcasting TV engineering, multi-media meeting
room, big screen display engineering, television education, command control center or
other fields. It provides power-fail locale protection function, LCD displaying, A/V timing
or separate switching function. It also has a adaptable compensation to extend the input
distance to 70 feet. With RS232 interface, it can be worked with PC, remote control
system and any other 3rd party control system devices. The user manual takes DVI0808-A
as an example, other models can take reference from it too.

3. Installation

DVI matrix switchers adopt metal shell and can be stacked with other devices. They are
rack-mountable and can be installed on a standdard 19 inches rack. It is recommended to
leave a 1U space between the units to have easy access for installation of the cables.

5. Operation and Control

5.1 RS232, LAN and 3rd Party Control

The Switchers can be controlled by front controls or PC, CRESTRON control system,
AMX control system, ) or through the Ethernet control via the RS-232 communication port.
The RS232 is female 9-pin D connector. It can be switched b y several control systems.
When the switcher connects to the COM1 or COM2 of the computer with control software,
users can control it by that computer. To control the switcher, users may use the application
SWITCHER 2.0 in the supplied CD or develop their own control software.

Atlona Technologies www.atlona.com 6

5.2 Connecting using Input and Output Terminals

The DVI matrix switch may take DVD players, computers, graphic workstations
and other digital NON HDCP SIGNALS as their input signal source. The switch
can out to projectors, video recorders, displays and other DVI NON HDCP displays
depending on the application.

5.3 Connecting and Setting up Audio

“AUDIO INPUTS”, “AUDIO OUTPUTS” audio network interface in DVI matrix switch­ers can be connected to the audio signal and amplify sources. Audio connection is little
more complicated than video. It has two types of connection: balanced and unbalanced. The
balanced connection transmits a pair of balanced signals with two cables. Because Inter­ferences will have the same intensity and the opposite phases on the two cables; it will be
counteracted in the end. For the low frequency extent of the audio signal, it would be easily
interfered under long distance transmission. Therefore as an anti-interference connection, it
is mostly used in Audio connection of special high end devices.

Atlona Technologies www.atlona.com 7

The unbalanced connection transmits signals only with one cable. Without counteraction,
it can be interfered more easily. Accordingly, it is adopted for household appliance or some
cases with low technical demand. Take the audio signal line for example: 1.Unbalanced: pin
“G” connect to SLEEVE, pin “+” connect to TIP, pin “–” connect to pin “G”; 2.Balanced:
pin “G” connect to SLEEVE, pin “–” connect to RING, pin “+” Connect to TIP.
To select which connection is up to the interface of the device. When available, the balanced
Connection is the first choice.

Before connecting, please read the command or relevant demand in the user manual care­fully. In some cases, there is balanced in source signal end but unbalanced in the destination
end. If in a nonstandard case, it is done to connect balanced for the balanced end and unbal­anced for unbalanced end. But if in a standard one, the converter must be used to switch the
signals as the same, balanced or unbalanced.
