General Settings Table 3 Baud Rate 9600 Data Bits 8 Stop Bits 1 Check Bits Null 2. Communication Commands There are two kinds of communication, initiative upload mode and question & answer mode. We take initiative upload mode as the default settings. The module upload a gas concentration value every 1S, and the command line format is as follows: Table 4 Gas concentration value = (High Byte*256+Low Byte) x 0.1 Please note that in the above calculation formula, the byte4 and byte5 means the decimalism value changed from hexadecimal. For example: Original byte4 is 1B and original byte5 is 2C. 1B is hexadecimal and it is 27 after changing to decimalism. 2C is hexadecimal and it is 44 after changing to decimalism. So, concentration= (27x256+44)x0.1 Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte6 Byte 7 Byte 8 Start Byte Gas Type Unit No. of decimal Concentration (High Byte) Concentration (Low Byte) Full Range (High Byte) Full Range (Low Byte) Check sum 0xFF CO=0x04 ppm=0x03 1= 0x01 0x00 0x25 0x13 0x88 0x25
