7. VAN Protocol
7.1. Line Interface
There are three line inputs and one line output available on the TSS461C. Which of the three inputs to use is either
programmable by software or automatically selected by a diagnosis system.
The diagnosis system continuously monitors the data received through the three inputs, and compares it with each other
and the selected bitrate. It then chooses the most reliable input according to the results.
The data on the line is encoded according to the VAN standard ISO/11519-3. This means that the TSS461C is using
a two level signal having a recessive (1) and a dominant (0) state. Furthermore, due to the simple medium used, all
data transmitted on the bus is also received simultaneously.
The VAN protocol is hence a CSMA/CD (Carrier Sense Multiple Access/Collision Detection) protocol, allowing for
continuous bitwise arbitration of the bus, and non-destructive (for the higher priority message) collision detection.
Node a: TxD
Node a loses the arbitration
Node a releases the bus
Node b wins the arbitration
Node c loses the arbitration
Node c releases the bus
