4.2.3 Information frame on configuration of Digital Input(s)
The 0x1F frame is sent when the device starts up.

Description of the frame:
Bytes 2: register 380, configuration of the button alarm (Digital Input 1)
Bytes 3 and 4: register 381, configuration of the threshold of the alarm button (Digital Input 1)
Byte 5: register 382, configuration of the alarm of the terminal block (Digital Input 2)
Bytes 6 and 7: S383 register, configuration of the terminal alarm threshold (Digital Input 2)
In the example in grey, this results in:
Byte 2: S380 = 0x41, the device will wait for a buffer period of 100 ms before sending an high change of state detection
Bytes 3 and 4: S381 = 0x0001, i.e. 1 in decimal, the device will send an alarm each time a button is detected
Byte 5: S382 = 0x41, the device will wait for a buffer period of 100 ms before sending an high change of state detection
Bytes 6 and 7: S383 = 0x0001, i.e. 1 in decimal, the device will therefore send an alarm for each detection on the terminal block
In the example, as soon as a button press (Digital Input 1) is detected (pressure longer than 100ms), an alarm frame linked to the button will
be sent. Same for the terminal block input (Digital Input 2).
4.2.4 Information frames on Network configuration
When switching to operating mode (PARK or COMMAND mode output), the following frame (0x20) representing the application configuration
of the device is transmitted:

Its size is 4 bytes.
Description of the frame:
Byte 2: S220 register: Enabling the Adaptive Data Rate
Byte 3: S221 register: Connection mode
In the example in grey, this results in:
Byte 2 = 0x18: Adaptive Data Rate is enabled
Byte 3 = 0x01: OTAA connection mode
4.2.5 Keep alive frame
This frame (0x30) is transmitted at the frequency defined by the register 300 only if no periodic data is defined or in alarm mode on a threshold
overflow (S301 = 0).
