sigfox ANALOG PWR - Guide utilisateur / User guide version V1.2.0
In the example in grey this gives:
• Byte 2=0x02: register 302, channel A configured for a 4-20mA sensor
• Bytes 3 to 5=0x0C3500=800,000 in decimal i.e. A value measured on channel A of: 800,000,x10=8,000,000nA i.e. 8mA
• Byte 6=0x01: register 304, channel B configured for a 0-10V sensor
• Bytes 7 to 9=0x4C4B40=5,000,000 in decimal i.e. a value measured on channel B of: 5,000,000 µV i.e. 5V

Description de la trame :
• Byte 2: Type of the sensor on channel A. Configured by the user (register 302).
• Bytes 3 to 5: Value measured on channel A.
• If the type of sensor is 0-10V: The value is expressed in µV
• If the type of sensor is 4-20mA: The value is expressed in nA
• Byte 6: Type of the sensor on channel B. Configured by the user (register 304).
• Bytes 7 to 9: Value measured on channel B.
• If the type of sensor is 0-10V: The value is expressed in µV
• If the type of sensor is 4-20mA: The value is expressed in nA
