LoRaWAN US902-928 Pulse - Guide utilisateur / User guide version V1.0.0
In the example in grey this gives:
• Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 1 (second frame)
• Bytes 3 to 4 : Delta A0 : index variation of channel A during the time interval between 10 to 20 minutes after transmitting the previous
frame = 0x0012 so 18 additional pulses
• Bytes 5 to 6 : Delta B0 : index variation of channel B during the time interval between 10 to 20 minutes after transmitting the previous
frame = 0x0020 so 32 additional pulses
• Bytes 7 to 8 : Delta A1 : index variation of channel A during the time interval between 20 to 30 minutes after transmitting the previous
frame = 0x0007 so 7 additional pulses
• Bytes 9 to 10 : Delta B1 : index variation of channel B during the time interval between 20 to 30 minutes after transmitting the previous
frame = 0x0010 so 16 additional pulses

Description of the frame:
• Byte 2: frame index: index of this frame in a multi-message sequence
• Bytes 3 to 4 : Delta A2 : index variation of channel A during the time interval between 30 to 40 minutes after transmitting the previous
frame.
• Bytes 5 to 6 : Delta B2 : index variation of channel B during the time interval between 30 to 40 minutes after transmitting the previous
frame.
• Bytes 7 to 8 : Delta A3 : index variation of channel A during the time interval between 40 to 50 minutes after transmitting the previous
frame.
• Bytes 9 to 10 : Delta B3 : index variation of channel B during the time interval between 40 to 50 minutes after transmitting the previous
frame.
In the example in grey this gives:
• Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 2 (third frame)
• Bytes 3 to 4 : Delta A2 : index variation of channel A during the time interval between 30 to 40 minutes after transmitting the previous
frame = 0x0100 so 256 additional pulses
• Bytes 5 to 6 : Delta B2 : index variation of channel B during the time interval between 30 to 40 minutes after transmitting the previous
frame = 0x00F0 so 240 additional pulses
• Bytes 7 to 8 : Delta A3 : index variation of channel A during the time interval between 40 to 50 minutes after transmitting the previous
frame = 0x0000 so aucune pulses
• Bytes 9 to 10 : Delta B3 : index variation of channel B during the time interval between 40 to 50 minutes after transmitting the previous
frame = 0x0015 so 21 additional pulses
Frame 4/4 :

Description of the frame:
• Byte 2: frame index: index of this frame in a multi-message sequence
• Bytes 3 to 4 : Delta A4 : index variation of channel A during the time interval between 50 to 60 minutes after transmitting the previous frame.
• Bytes 5 to 6 : Delta B4 : index variation of channel B during the time interval between 50 to 60 minutes after transmitting the previous frame.
In the example in grey this gives:
• Byte 2: frame index: index of this frame in a multi-message sequence (always null in this configuration) = 3 (fourth frame)
• Bytes 3 to 4 : Delta A4 : index variation of channel A during the time interval between 50 to 60 minutes after transmitting the previous
frame = 0x074A so 1866 additional pulses
• Bytes 5 to 6 : Delta B4 : index variation of channel B during the time interval between 50 to 60 minutes after transmitting the previous
frame = 0x003B so 59 additional pulses
