7 Data transmission to the server from connected sensors
7.1 Description of ADM31 sensors parameters transmitted to the server
Data from ADM31/32 sensors is transmitted in CAN data packet together with other data in
each message. There are 5 CAN fields for each sensor. The correspondence of CAN fields to the
transmitted data type is given in table 3. The sensor number given in the table corresponds to the
number of the added sensors list.

7.1.1 Conversion of incoming data at the server side
Since CAN data packet is universal, calculation formulas are not applied to these fields on
the servers.
To convert values to a readable format, the following calculation formulas described below
should be applied to the incoming values.
To prevent values jumps when there is no communication with the sensors, it is
recommended to set a range of permissible values on the software side. Or apply other filters
supported by the software you use.
