This class implements the NIPB::IProtocol interface. It handles a
|
||
|
|
proprietary signal protocol for the Vector Conecept Car Ethernet
|
||
|
|
Network.
|
||
|
|
|
||
|
|
The protocol is located within a UDP protocol and uses the UDP
|
||
|
|
ports 40001. The first 32bit of the UDP payload are the content ID.
|
||
|
|
The 32-bit content ID represents the header of this Signal protocol.
|
||
|
|
The payload of this protocol is interpreted by the DBC.
