2.2.3 Transmission of a daily Keep Alive frame
In the event (threshold) mode only, it is possible that the product would never send data frames. So to be sure that it is working properly a Keep
Alive frame is transmitted regularly according to the following diagram:
2.2.4 TEST mode
This mode allows the user to perform tests of the product more quickly by reducing the time scales of the production mode and modifying the
behavior of the LEDs.
It is obtained by positioning register S306 at the value 2 in the COMMAND mode. Once out of the command mode, the product returns to the
previously defined application behavior but with the following changes:
- register S300: the periodicity of the Keep Alive is expressed in groups of twenty seconds instead of tens of minutes. Hence in test mode when
register 300 = 144, the Keep Alive is no longer sent every 144x10min=1440 minutes or 24h but every 144x20s=2880 seconds or 48 minutes.
- register S301: the periodicity of the sending of data (periodic mode) is expressed in groups of twenty seconds instead of tens of minutes.
Hence in test mode when register 301 = 1, the Keep Alive frame is no longer sent every 10min but every 20 seconds.
- register S332: the periodicity of the data acquisition (event mode) is expressed in tens of seconds instead of minutes.
Hence in test mode when register 332 = 1, the Keep Alive frame is no longer sent every minute but every 10 seconds.
-The LEDS also have a different behavior, allowing a visual feedback to the user in the event of transmission and reception of frames (see para-
graph 2.3 for more details).
A complete list of the registers can be found in paragraph 3.4.

In event mode the acquisition period is: 10x10=100 seconds
In periodic mode (register 301 different from 0), there is no Keep
Alive frame transmission.
The settings associated with this mode of operation are:
• The setting of the period of transmission of the Keep Alive frame
(once per hour to once per day) (register 300).
