CAN Bus
The CAN bus is used for:
• Configuration, firmware upgrade and event download through ADR Manager.
• Transmission of ADR status.
• Receiving external channels to be stored in the event log.
Transmit Messaging
There are two status messages transmitted from the ADR at 50Hz on user configurable CAN Ids:
CAN Address Bytes Description Units
