Instruction Set Description:
1 , sensor readings word
2, set the module number
3 , the module zeroed
4, the full value of the module calibration
5, the module returns data
-------- 1-5 command all compatible command protocol compatible with the DL100
6 , baud rate setting
7 , any weight load calibration
8, AD sampling rate settings
9, AD filter depth settings
10 , set the module continuous transmission
11 , set the module sends the data delay
12 , set the scale value and zero tracking
13 , set the boot set to zero and the decimal point
14 . Module initialization
-- -- -- -- 6 to 13 instructions for the new instruction set
-- -- new instruction analysis:
9, the baud rate setting: the new command will make the model of arbitrary set an appropriate rate in support of the baud rate, to suit different applications;
10, setting module continuous transmission: in a one to one correspondence, only the upper machine sent once this command, AD module can automatically results automatically sent to the host computer, convenient PC operation (this command to shut down after the invalid);
11, setting module sends the data delay: delay parameter set free, can satisfy some slow PC contradiction in speed, ensure the return data will not be lost;
12, 13, set the index value and zero followed, set the zero and decimal point: can make the module has a simple instrument function, realize the basic weighing function, and not just as a AD conversion module.
14, the module initialization: recovery module all parameters to factory value.
