1.Introduction
1.1 About DVI Matrix Switcher System
MDV 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 signal. Independent
DVI component and balance/unbalance I/O terminals make each component signal transmit and
switch separately; this design can reduce attenuation of 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. A/V
timing or separating switching function. It also has an adaptable compensation to extend the input
distance to 36 meters. With RS232 interface, it can be worked with PC, remote control system
and any other far-end control system devices. The user manual takes MDV88Apro as example,
other models can take reference from it too.

5.1 Introduction of the Input and Output Connectors
According to different type of matrix, computer signal I/O interface are made up of 8-channel
BNC ports and DVI-D female ports respectively. audio signal I/O terminals are make
up of 8-channel BNC ports and Captive screw connectors ports respectively. Please refer to
shell silk-screen figure about other types of interface.
5.2 Connection of RS-232 Communication Port
Besides the front control panel, the DVI matrix switcher can be controlled by far-end control
system or through the Ethernet control via the RS-232 communication port.
5.2.1 Connection with Control System
With the RS-232 port, the DVI matrix switchers can be controlled by several kinds of control

Audio signal connection:
“AUDIO INPUT”, “AUDIO OUTPUTS” audio network interface in DVI matrix switchers (MDV) can be
connected to the audio signal and amplify of the DVD player.
Audio connection is little complicated than video. It has two kinds of connection: balanced and
unbalanced.
The balanced connection transmits a pair of balanced signals with two signal cords. Because
interferences will have the same intensity and the opposite phases on the two signal cords, 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 device.
The unbalanced connection transmits signals only with a signal cord. 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. As shown in the F 5-3:

F5-3 5 bit 3.8mm Balanced/unbalanced connection on captive screw connector. To select which
connection is up to the interface of the device. When available, the balanced connection is the first
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 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.
