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.

Matrix Switch Communication Protocol
The RS-232/RS-485 communications are half-duplex with variable byte
count packets. For RS-232, the matrix switch operates as a DCE device
and therefore can be connected using a straight cable to a DTE device
such as a computer. The RS-232 connector is a DB-9 female. For RS-485, a
discrete wiring connector is provided for custom connection to any
RS-485 equipment. For full details on connecting to the matrix switch refer
to the User Manual.

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.
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
1. The matrix front panel switching keys not responsive?
Answer: The matrix front panel keys employ scanning testing and require longer
response time. Press the keys for 2 seconds and then release. This way, key switching
will be responsive in operation.
2. The matrix does not display or color display is abnormal after hot plug?
Answer: Switching of the signals goes through the matrix ICs. If the voltage difference
between the input signal equipment and the matrix equipment is too large, hot plug
could easily cause damage to the matrix switches. Turn off power to the system before
plugging or unplugging.
3. Ghosting happens when YPbPr signals output to display?
Answer: Ghosting is often caused either by the projector, inferior cable quality or
long transmission distance. Adjust the projector or replace with better quality cable.
4. Loss of color reproduction happens or no video signal output?
Answer: Check if connectors at both ends of the YPbPr signal cable are correctly
connected.
5. The serial port fails to control the matrix?
Answer: Check that the communication port set by the control software is correctly
connected to the corresponding serial port of the equipment. Verify the serial control
parameters (9600, 8, N, 1).
6. The corresponding graphics fail to output during matrix switching?
Answer:
(1) Check for a signal on the input end. If there is no input signal, it could be that
the input connection cable is broken or the connector is loose. Repair or
replace the connecting cable.
(2) Check if there is signal on the output end. If there is no output signal, the cable
could be broken or the connector is loose. Reseat or replace the connecting cable.
((3) Check if the output port number is the same as the controlled port number.
((4) If none of the above circumstances happen, it could be internal failure of the
product itself. Call 469-429 9200 for technical support.
7. The power LED is not on, LCD has no display and no response in operation?
Answer: Check if the equipment power input is good. Check the power at the AC
outlet and that the power cord is firmly connected at both ends.
8. Power leakage sensed during plugging or unplugging of the audio/video ports?
Answer: It could be that the equipment power is not properly grounded. Properly
ground the equipment, otherwise product life may be shortened.
9. The LCD displays normally, the communication port shows good return codes, but
displays no graphics or audio output?
Answer: (1) It could be that the audio/video connectors are loose. Replace the
connectors.
(2) It could be the connection cable short-circuited. Replace the cable.
(3) It could be the connection cable is broken. Replace the cable.
10. The matrix panel keys and communication ports are out of order?
Answer: Check if the equipment power input is good and the computer
communication ports are good. If the connections are good, it could be failure of
the product. Call 469-429-9200 for technical support.
11. Operation and function failure occurred?
Answer: Check if the equipment and the matrix system are properly connected. If the
problem persists, Call 469-429 9200 for technical support.
COMMON PROBLEMS & SOLUTIONS
YPbPr-RCA Connecting Cables
Audio Connecting Cables

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 corre-
spond 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.
