Transponder module and access module for activating and configuring such transponder module over a CAN bus
First Claim
1. A method for establishing a data link between an access module and a transponder module;
- comprising;
the access module connected to a CAN bus sending one or more announce CAN messages over the CAN bus to one or more transponder modules connected to the CAN bus, each of the one or more announce CAN messages comprising a payload, the payload comprising an answer CAN address for dynamically assigning the answer CAN address to one of the one or more transponder modules;
the access module receiving one or more request CAN messages from the one or more transponder modules wherein each of the one or more transponder modules is associated with a transponder ID, each of the one or more request CAN messages comprising an answer CAN address and a transponder ID of one of the one or more transponder modules; and
the access module selecting a transponder module based on the one or more request CAN messages for establishing the data link.
