Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a device arrangement to derive unknown portions of a communication data scheme. A proxy node is established in a communication path between two nodes configured to transmit communications according to a communication bus standard. The communication data included in the communications transmitted between the nodes conforms to a communication data scheme. The proxy node logs communications transmitted between the nodes via the communication path, resulting in a communication log. The communication log can then be used to derive unknown portion of the communication data scheme, such as commands for requesting specified data types and the data format for transmitting data of specified data types.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a variable multiplexer for vehicle communication bus compatibility. A device includes a variable multiplexer that can be electronically configured to a desired pinout configuration to provide compatibility with multiple vehicles. For example, the variable multiplexer may be electronically configured based on a pinout configuration used by the vehicle to connect pins in the device to the corresponding pins on the data link connector that provide the same specified function. The device may therefore use a single standardized cable with vehicles using a variety of pinout configurations.
