Installation Instructions
Chapter7. Installation instructions
7.1. Signal connection
The matrix interface is divided into signal input and output
interface,please use the corresponding cable to connect the input and
output devices, the signal source (such as DVD, computer etc.) output
terminal matrix input device (INPUT), the matrix output (OUTPUT)
connected to the Input interface of signal equipment (such as
projector, TV etc).
7.2. RS232 Communication interface connection
Matrix switch provides a standard RS-232 serial communication
port and RJ45 communication port, users can use a variety of remote
control equipment remote control. The RS-232 port of the matrix is a
D shaped 9 pin male connector (the same as the serial port of the
computer)Pin descriptions are as follows:

Attention: matrix RS-232 port and the computer or the central control,
should pay attention to the TXD and RXD line sequence,specifically to
consider the other device pin definition.
7.3. RJ45 for TCP/IP control
The network matrix is supported by the TCP/IP protocol. When the
matrix is connected to a switch or router or PC directly, the matrix
can communicate. The premise is to keep the IP address of the matrix
and the LAN to be the same segment, otherwise the IP address of the
set matrix should be entered first.

Installation Instructions
7.4. RJ45 for RS232 control

The diagram below is a schematic diagram of the connection with
the computer：
7.5. Power connection
Please connect one end of the power cord to the back of the
matrix with a power supply interface of AC100-240V 50/60HZ, which
connects to the 100-240V 50/60HZ AC power supply. Note that in
order to ensure the safety and normal operation of the equipment,
a single-phase three wire AC power supply.

8.2. RS232 serial control parameter
The baud rate is set to 9600, 8 bit data bits, 1 bit stop bits, no parity bits, and communication
mode: asynchronous half duplex serial communication.
8.3. Communication control protocol
The following protocols support all types of matrices, including VGA series, DVI series and HDMI
series Matrix:
For example:
1D1V1,2,3.
When ID is 0, you can use all the matrix. ID value 0~99.The matrix ID is 1 and the input channel 1
is switched to the output 1,2,3 channel sequentially.
16X16 matrix. 2D12V12,2,14,1.
The matrix ID is 12, and the input channel 12 is switched to the 12,2,15,1 channel of the output
channel once.

◆ Standby Image (LCD Screen)
Any state press "ESC" to return to the screen (different models, slightly
different).
◆ "AV button" audio and video switch Press the AV button to enter the audio and
video synchronization switch menu, as shown below; in this state, with the number
keys to select the input channel number and output channel number, and then press
the OK key to switch. Select the "ALL" key instead of all output channels. For
example, to switch the 1 input channel to all output channels, press "AV" - "01" -
"ALL" -"OK".
◆ "FUN" function key In standby mode, press "fun" button to enter the system
operation menu,the menu can be stored in the scene and call function, and restore

Common faults and maintenance
Chapter11. Common faults and maintenance
◆ When the matrix peripheral image display device has ghosting, such as ghosting
when the projector is not the main problem, in general, may be adjusted without the
right projector or wire quality standards, with the corresponding projector button
to adjust or replace the wire.
◆ When the color loss or no video signal output, audio and video interface may
be bad contact.
◆ When the remote control can not control the matrix:
1.may be the battery is dead, please replace the battery.
2.may be the remote control is broken, please repair.
◆ When the serial port can not control the matrix, check whether the communication
port of the control software is corresponding to the serial port of the connected
device.
◆ There is no corresponding image output when the matrix is switched:
1.check whether the corresponding input signal. (can be used oscilloscope or
multimeter for testing) if there is no signal input, it is possible that the input
line broken or loose joints, try to replace the wire.
2.check the corresponding output signal. (can be used oscilloscope or multimeter
for testing) if there is no signal output, it is possible that the output line is
broken or loose joints, try to replace the wire.
3.check whether the output port number is consistent with the controlled port
number.
4.does not belong to the above three kinds of situations, may host internal fault,
please send professional maintenance.
◆ If the POWER lamp does not light, and the LCD is not displayed, the operation is
not responding, please check whether the power input is good.
◆ The output image is disturbed, it is possible that the input and output devices
do not have good grounding.
◆ When pulling, inserting audio video interface, if you feel there is a clear
static,
it is possible that the equipment power supply ground wire is not a good grounding,
according to the correct method of grounding, otherwise easy to damage the host,
shorten the life of the mainframe.
◆ LCD display normal, the communication port has a return code, but no image
output or no audio output
1.audio and video interface may be loose, can be replaced.
2.short circuit may be connected, try to replace the wire.
3.possible wiring break, try to replace the wire.
◆ When buttons, communications, remote control can not be controlled, the host may
have been damaged inside, please send for professional maintenance.
