Summary Of The Conditions Of The Transmission Of The Uplink Frames; Downlink Frames; Product Configuration Request Frame - ADEUNIS ARF8190BA Guide Utilisateur

LoRaWAN 863-870 ANALOG - Guide utilisateur / User guide version V2.0.1
Frame description:
• Byte 2: Type of the sensor on channel A. Configured by the user (register 320).
• 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 322).
• 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
In the example in grey this gives:
• Byte 2=0x02: register 320, 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 322, 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

4.1.7 Summary of the conditions of the transmission of the uplink frames

4.2. Downlink frames

LoRaWAN technology makes it possible to transmit information to the product from the network (downlink frame).
The class A of the LoRaWAN specification allows the product to receive information from the network by proposing two listening windows after
each uplink communication (uplink frame).

4.2.1 Product configuration request frame

This frame allows us to inform the product via the network that it must resend the product configuration uplink frame (0x10).
