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.

2.0 Introduction
The VGA series switcher is a high-performance professional computer and audio signal switcher that
can be used for cross switching multiple computer and audio signals. The VGA series switcher mostly ap-
ply in broadcasting TV engineering, multi-media meeting room, big screen display engineering, television
education, command control center or for other like applications. It provides power-fail locale protection
function, LCD displaying, shortcut selecting and saving function. With RS232 interface, it can be controlled
with PC, remote control system and any other 3rd party control systems. This user manual takes VGA0808
as the example; other models can take reference from it too.

2.1 Installation
The VGA Switchers can be easily rack mounted using the rack mount ears located in the front of the
unit. Secure the Switch with standard rack-hole screws. It is recommended to leave a 1U space be-
tween the units to have easy access for installation of the cables. When connecting the cables make
sure all cables are connected correctly if not it could cause color loss or will not output a display signal.

3.0 Connecting the Swticher
The VGA matrix switchers connect using female 15-pin HD connectors for the video signal I/O interface,
and captive screw connectors for the audio signal I/O interface. The swticher has front control panel, infra-
red remote controller (Optional) and the Ethernet control (Optional), The VGA switcher can also be control-
led via the RS-232 communication port. This RS-232 communication port is a female 9-pin D connector.
The denition of its pins is shown in the table below.
Pin RS-232 Description
1 N/u Not used
2 Tx Transmit data
3 Rx Receive data
4 N/u Not used
5 Gnd Signal ground
6 N/u Not used
7 N/u Not used
8 N/u Not used
9 N/u Not used
The switcher can also be controlled through COM1 or COM2 ports on the computer, To control the switch-
er, users may use the application SWITCHER 2.0 in the supplied CD or develop their own control software
with the protocol and control codes.

3.1 Connecting with inputs and output terminals
The VGA matrix switchers may take laptops, desktop computers, graphic workstations and document
cameras as their input signal source. Projectors, RP TVs, displayers and ampliers can be connected on the
output signal .
VGA Connection: The VGA matrix switchers support all kinds of the RGB and VGA signal sources with 15-
PIN HD VGA connectors.

If the RGB source does not have VGA output terminals, please convert the signals with an RGB to VGA
converter for getting high quality VGA output. Please use the special VGA cable to connect the input and
output devices. Connect the 15-Pin HD connectors carefully.
3.2 Audio signal connection:
“AUDIO INPUTS”, “AUDIO OUTPUTS” audio network interface in RGB matrix switchers can be con-
nected 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 bal-
anced 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

Page 10
The unbalanced connection transmits signals only with one cable. Without counteraction, it can be inter-
fered more easily. Accordingly, it is adopted for household appliance or some cases with low technical de-
mand. 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 rst choice. Before connection, please read the command or relevant demand in the user
manual carefully. In some cases, maybe there is balanced in source signal end but unbalanced in the destina-
tion end. If in a nonstandard case, it is done to connect balanced for the balanced end and unbalanced
4.0 Stacking The Switcher
When stacking the vga matrix switchers the slave matrix inputs 1-32 become inputs 33-64, that also goes for
the 3rd matrix slave making inputs 1-32 to 65-96. If all 3 matrix swtichers are stacked it would make the
unit 96x1.

6.1 Keyboard Tab
Because the function buttons on this tab are the same with the ones on the front control
panel, it shares the same control operation and command format with the control panel.
Please refer the details in Chapter 7 Operation of the Control Panel
6.2 Auto Tab
This tab is used to test the switcher after connecting it to all the input and outputs device. For example, to
test the function of an RGB64X32 matrix switcher, the Auto Tab is set as below after nishing all the con-
nection.
Switch Mode: “AV”
INPUT: From 1 to 64
OUTPUT: From 1 to 32
Delay: 1000ms (1 second)
Click on the button “START” to perform the test, the matrix switcher will:
Transfer the signals from input channel No.1 to output channel No.1-32;
Transfer the signals from input channel No.2 to output channel No.1-32;
Transfer the signals from the input channel No.64 to the output channel No.1-32;
This switching test will perform this way one by one every second until the test is over.
