Operating Instructions
Thanks for purchasing our product.
Please be sure to read this instruction manual
carefully before using our product.

Introduction
Grandbeing’s MX0808-31F is an 8-by-8 HDMI in HDMI out matrix. It allows any
of the eight Inputs to be routed to any of the eight Outputs simultaneously, no
matter the source is HDCP or not. When sources’ video formats are same,
outputs can switch between sources seamlessly. If sources’ formats are
different, switch time will be very fast.
Users can choose several different ways to control the matrix: by using infrared
extension receiver, RS232, RS485, and LAN and supplied remote control. IR
emitters in the matrix are for controlling the sources; the IR control signal could
be from remote locations when work with EX0101-H01 and EX0101-H02.
Also provide Optical SPIDF out for every HDMI OUT.
MX0808-31F offers solutions for digital entertainment center, HDTV retail and
show site, HDTV, STB, DVD and projector factory, noise, space and security
concerns, data center control, information distribution, conference room
presentation, school and corporate training environments.

4) Control command format.
If user want to write his own control software, below are data format and baud rate setting.
Com port setting:
Baud Rate: 9600 bps
Data bits: 8 bits
Parity: None
Stop bits: 1 bit
Flow control: None
The command format as follow:
Cir + ‘_’ + code + ‘ ’↙
“Cir” is the key word, ‘_’ is Space, “Code” is the Control code, and ‘↙’ is carriage return. For
example:
“Cir 39↙” (hex: 63 69 72 20 33 39 0D 0A), when the MX0808 received this command, it will
change the Outport4 status to the next input port. (“c”-0x63,”I”-0x69,”r”-0x72,”
“-0x20,”3”-0x33,”9”-0x39, ‘↙’-0x0d0a)

When you send a control command to the MX0808, if succeed, it will feedback current output
port status to show which input port is selected. The return status format is as follows:
For example, if you send “cir 44↙” to MX0808,if succeeds, it will feedback “s55\r\n”, meanings
Output5 selects Input5.
6) Read Status Command
The command length is 4 bytes.
bc + ‘_’ + ‘ ’↙
“bc” is the key word, ‘_’ is Space, ‘ ’ is carriage return.↙
When you send the read status command to MX0808, if succeeds, it will feedback the status of
all outputs. When you send “bc” to MX0808, if succeed, it will feedback the current status of
MX0808.
For example, if you send "bc ↙"to MX0808,if succeeds, it will feedback
"s11\r\n" ,"s22\r\n" ,"s33\r\n" ,"s44\r\n" ,"s55\r\n" ,"s66\r\n" ,"s77\r\n" ,"s88\r\n". it means that
the output 1 select the input 1, the output 2 selects the input 2, output 3 selects the input3,
output 4 selects the input 4, output 5 selects input 5, the output 6 selects the input 6, the output
7 selects the input 7, the output 8 selects the input 8.
7) Web password reset
The command length is 4 bytes.
rpw+ ‘↙’
“rpw” is the key word , ‘↙’is carriage return.
When you send the Web password reset command to MX0808, if succeed, it will feedback
"rpw", and the web password will be set as "0000000000".
