1.0 Safety Operation Guide
***************************************************************
In order to ensure the credibility and the user’s safety, please comply with the fol-
lowing 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 AV 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 AV 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 VGASwitchers 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 between the units
to have easy access for installation of the cables. When connecting the cables make sure all cables are con-
nected correctly if not it could cause color loss or will not output a display signal.
Packaging Includes
• VGA Matrix Switcher
• RS-232 Communication Cord
• Power Supply Cord
• CD with Application SWITCHER 2.0
• User Manual and Quality Guarantee
• Remote Control

3.0 Connector Types
The AV matrix swticher uses 2 types of Video Connectors for 4 Channel and 8 Channel RCA terminals are
used. For 16 Channel, 24 Channel, 32 Channel, 48 Channel, 64 Channel, 96 Channel, 128 Channel BNC fe-
male terminals are use. Audio signal I/O terminals make up of 2 Channel, 4 Channel, 8 Channel, 16 Chan-
nel, 24 Channel, 32 Channel, 48 Channel, 64 Channel, 96 Channel 128 Channel with 3.8mm captive screw
connectors(or RCA terminals). The AV1616 switcher signal I/O terminals are form Channel 1 to Channel
8 and Channel 9 to Channel 16 (form left to right, display in two rows), The interfaces are video terminals
(BNC), audio left state terminals (white RCA), audio right state terminals (red RCA). The AV switcher can
also be controlled via the RS-232 communication port. This RS-232 communication port is a female 9-pin
D connector. The denition of its pins is shown in the table below.
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 the AV Switcher
The VGAmatrix switchers may take laptops, DVD players, video tape recorders, camcorders, cable TV
and video their input signal source. Projectors, RP TVs, displayers and ampliers can be connected on the
output signal .

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.
