Matrix System Overview
Matrix System
The Matrix Switch is a high performance system used to switch audio/video
frequencies. It will cross switch multiple input/output audio/video signals through
independent Y/Pb/Pr component and audio input/output terminals. Each Y/Pb/Pr component
signal and audio signal is transmitted separately and switched separately, thereby minimizing
signal attenuation and ensuring high definition graphics and high fidelity audio signal output.
The primary use is; TV broadcasting projects, multi-media conference halls, large display
projects, TV teaching, and command control centers. It features power interruption
protection during power surge, LCD display, and synchronous and separate audio/video
switching functions. The RS-232 and RS-485 communication ports enable convenient
communication with remote control equipment. This manual describes the SW404HD and
SW808HD models.

Input/Output Jacks
Dependent on the matrix model installed, the video signal input/output jacks are arranged in
either 4 or 8 columns of RCA female connectors. The connector rows from top to bottom are:
Y video (green), Pb/Cb video (blue), Pr/Cr video (red), right audio signal (red), and left audio
signal (white). The input and output jack channels are numbered from left to right as 1 to 8
(or 1 to 4). Refer to the drawing above for other types of connectors. The model numbers of the
matrix systems describe the number of input/output connectors. Example: Model SW404HD
has 4 input sets and 4 output sets.
Connecting Audio/Video Cable
The matrix supports various AV video signal sources. Users can connect inputs and outputs to
different audio/visual equipment such as: CD/DVD players, graphics workstations and number
displays, projectors, video recorders, displays, multiplexers, and etc.
Audio/Video Ports
The RCA Jack used is a standardized audio/video connector. It uses coaxial signal connections
in the center conductor and the outer ring for grounding. It will transmit digital audio signals and
video signals.
Video I/O (3-RCA) Connectors
The Y/Pb/Pr connector is a high definition digital TV
connector (color contour Y/Pb/Pr) capable of
connecting with high definition digital set-top box,
satellite receiver and various high definition
monitors and TV equipment. There are separate
connectors for the Y, Pb, and Pr signals. YPbPr-RCA Connecting Cables
Audio I/O (2-RCA) Connectors
Connection of the RCA audio cables is as shown below:
Normally RCA audio connectors are in pairs separately
indicated by red for the right audio channel (R for right)
and black or white for the left audio channel (L for left).
The RCA stereo cable is in one set for both left and right
audio channels with each channel in one cable. Audio Connecting Cables

Video

Matrix Switching System—Instruction Manual Page 5
Connection Method
The audio inputs and outputs can be separately connected to audio signal connectors of video
recorders and multiplexers.
Use the RCA cables for connecting AV equipment to the matrix. Connect the video and audio
connectors of the signal source equipment output terminals to the same channel connector of
the matrix input terminals. Connect the output of the matrix switch to the input connectors of the
interfaced equipment.
NOTE: The colors at both ends of the various signal cables must correspond to each
other, otherwise loss of color reproduction or even no signal output could
occur.
Control Computer Connection
Use the RS-232 cable (supplied) to connect the computer serial port to the RS-232
communication port of the matrix host. The computer can then be used to control the
matrix after installation of application software.
Matrix and Computer Connection
Remote Control Methods and Settings
The matrix provides standard RS-232 and RS-485 serial communication ports. The matrix
switching operation may be controlled locally using the front panel keys or remotely
through the RS-232 or RS-485 serial communication.

RS-485 Communication Port Connection Methods
The RS-485 port will control more than one product. The RS-485 Port is shown below.
A. DIP switch 8:(RS-232/RS-485 on/off)
ON:RS-232 enables single system or RS-485 serial master
OFF:RS-485 enables RS-485 serial slave B.
B. DIP switches 6 and 7 (RS-485 - terminator on/off)
ON enables Terminator
OFF disables Terminator
C. DIP switches 1 to 5 (ID address setting)
The ID address determines the position of a matrix within a system. When multiple Matrix
units are connected to one PC or when the Matrix units are serially connected, the ID
address decides which Matrix is controlled. The chart below describes the ID addresses.

signal transmission.

Page 16 Matrix Switching System—Instruction Manual
Examples for Selecting Matrix Switching Functions:
Example 1 (Audio and Video Switching): Using a SW808HD matrix having all the
input/output ports properly connected to the equipment. There are two methods to
set channel 1 audio/video to channels 2, 3 and 5 as output and channel 3 audio/video to
channel 6 for output:
First method: In the lower right corner of the blue area, enable the Video and
Audio functions (check the white boxes). To complete the switching operation,
directly click on the corresponding icons on the matrix to turn them into .
Second method:.
The following 3 steps sets the switching operation of Audio/Video input channel 1 to
output channels 2, 3 and 5 while at the same time switch Audio/Video input channel
3 to output channel 6.
Step 1: In the lower right corner of the blue area, enable the Video and Audio
