Communication command
The communication for MP3 is 2-wire or 4-wire Half-Duplex type by RS485. It is possible to
connect up to 31 units by using the prepared protocol for communication with PC.
The communication command of MP3 is R (Read), W (Write)
The communication parameters are for setting the communication conditions. Please refer to
the content below.
Communication protocol
Data structure
The MP3 communication uses ASCII strings, it possible to read and use the defined register.
There are 2 protocols that are selected due to the parameters. The standard protocol is STD,
the starting text is STX (0X02), and the ending text is ETX (0X03)
In the frame, the data are expressed with 10 decimals
Command
R
W
Discription
Read
Write
The R command sets the register number and the code to be read on the frame,
as a command that can read the register value
The W command sets the write data, register number and the code to be written on the
frame as a command that can write the register value
Ex. 1) Set value when reading the present value of code(01)
