Telemetry devices provide power to each of the attached sensors, acquire, process and transmit sensor data to
CIS. As soon as a message is received in CIS, it is decoded by the message decoder and stored in our database.
There are several message decoders to choose from when creating a new Device Type in CIS. A maximum of 32 Use Cases are associated with each message decoder. A Use Case is a combination of sensors connected to 1 telemetry device. Some Use Cases are reserved for special type of messages and do not necessarily contain sensor data. For example:
