4.4 EDID live erasing operation (unique for HDMI matrix)
Matrix address: 001
Baud rate: 9600
Prompt tone: enabled
Automatic switch: disenabled
Manual
21
EDID live erasing function can map the EDID information (i.e. displaying/receiving the EDID
information of device) of output terminal to input terminal of HDMI matrix.
4.4.1 When to perform EDID erasing
If the following situations happen during testing, perform EDID erasing to solve the problems;
1. Display screen is dark. The EDID of HDMI matrix input terminal may be incompatible with
screen’s resulting in the conflict between resolution of video source output and display screen, and
thereby failure of display. Erasing of EDID is required in this situation.
2. Display screen can support high resolution, for example, 1920×1200@60Hz, but if
1920×1200@60Hz is not available in video source terminal (for example, PC), erasing of EDID is
required in this situation.
3. When display screen cannot show the image in full screen, erasing of EDID is required in this
situation.

Chapter 6 instruction set
6.1 Preparation
Before use, please confirm carefully the following parameters are correctly set:
1) Baud rate is consistent with control device;
2) Confirm both ends of serial port line are straight-through, namely, pin-2 to hole 2, pin-3 to hole 3
and pin-5 to hole 5. Please refer to the instructions in previous chapters for details.
6.2 RS-232 serial communication protocol
Data bits: 8 Stop bit: 1 Check bit: none
1) Hexadecimal communication protocol:
Baud rate: 2400, 4800, 9600, 19200
2）ASCII communication protocol:
Baud rate: 2400, 4800, 9600, 19200
Data: ASCII
Baud rate: 2400, 4800, 9600, 19200
Data: ASCII
6.3 Control code
6.3.1 Hexadecimal control code
1. Control code is composed by 8 bytes:
Byte 1 is fixed to 0XA5 and “source address” is the number of control device. When matrix host is
controlled by multiple computers or devices, source address is used to distinguish. “Target address” is
the address of controlled devices and should be consistent with the internal setting of matrix host.
“Instruction” byte is used to distinguish different control instructions. Data 1, data 2 and data 3 is the
additional parameters of instructions. “Check” is the sum of byte 1 ~ 7 (when exceeding 1 byte, lower
byte part prevails). Device checks and verifies all the data. Only the right data will be interpreted and
executed; otherwise, wrong data will be abandoned and tips be shown on LCD screen.
Target address code: 01─FFH, FFH is broadcast code; default address of matrix host is 01H.
Note: the 8 bytes in control code are HEX format.
2. Example
Note: address code is 1.

1) Switch appointed input image and audio to appointed output.
For example: synchronously switch audio and video of input No.4 to output No.7.
A5 00 01 01 07 04 01 B3
2) Switch the input of one channel to all output channels.
For example: switch input No.4 to all outputs: A5 00 01 03 04 00 00 AD
3) Input and output one-to-one switch (CH 1 input is switched to CH1 output, CH2 input switched to
CH2 output)
A5 00 01 02 AA BB CC D9
6.3.2 ASCII Control Code
1. ASCII control code is composed by following
parts:
XX V XX .
Note: XX is the number of channels and the “.” at the
back cannot be neglected!
2. Example
Switch appointed input image and audio to appointed
output channel.
For example: synchronously switch audio and video
from input No.4 to output No.7.

The manual introduces the operation and parameters of system.
Chapter 8 Cautions and Trouble Shooting
8.1 Cautions
1) Power source: single-phase three-wire AC system (with PGND) is required. Make sure the
power source shares the same PGND and keep grounding pin in good conditions;
2）Hot plugging: hot plugging is forbidden lest circuit would be broken down (note: the damage
caused by hot plugging is excluded from warranty coverage);
3) Environment: prevent dust, moisture, heat accumulation and fall;
4) Maintenance: all maintenances should be handed over to professional personnel. Do not attempt
to do the maintenance on your own. To prevent electric shock, do not open the housing without
permission.
8.2 Trouble shooting
In the following cases, please make corresponding examinations first:
1) Ghosting can be seen in the images received. If the ghosting is created by projector, it is probable
that projector is not well-adjusted or bad quality of wires causes unmatched impedance which creates
Manual
29
secondary or multiple reflections. It is feasible to adjust the projector or replace wires.
2) When remote controller cannot control matrix:
A. An obstacle is in the way of controlled device;
B. Low battery. Please replace the battery. It should be noted that there is a protective film on the
battery of new remote controller. Please remove it before use;
C. Remote controller may be broken. Please contact our after-sale service;
3) When serial port RS-232 (usually refer to the serial port of computer) cannot control matrix,
check if the communication ports of software correspond to the serial port of device; if
communication port of computer is in good conditions.
4) If there is no beep sound during switching of input/output signal, it is probable that the software
has disenabled buzzer or buzzer goes wrong. Please call on professional personnel.
5) During matrix switch, buzzer, LCD display and serial port is normal, but there is no image
output;
A. Check the input terminals of row and field with oscilloscope or universal meter. If there is no
signal input, input cable may be broken or have a loose connector. Replace the connection wire;
B. Check the input terminals of row and field with oscilloscope or universal meter. If there is no
signal output, output cable may be broken or have a loose connector. Replace the connection wire;
C. If problem still remains after replacement, inside of machine may go wrong. Please hand over
to professional personnel.
6) Overlapping curve, ripple, shaking low-frequency interference can be seen in some channel. It
may be caused by bad contact of ground wire.
7) If static is obvious when releasing and plugging HDMI connector, ground wire of power source
may have bad contact with ground. Please ground the wire reliably; otherwise, it would be likely to
damage equipment or shorten the service life of host.
8) Panel keys, RS-232 and infrared remote controller don’t work. Inside of device may be broken.
Please hand over to professional personnel.
