a high-speed multimedia interface Multifunction Vehicle Bus – part of the Train Communication Network IEC 61375. SMARTwireX SPI VAN – (Vehicle Area Network) UAVCAN – (Uncomplicated Application-level Vehicular Communication And Networking) mostly used in electric aircraft, drones, satellites, and robotics. Physical transmission media Some examples of physical transmission media use in vehicle networks: Single wire Twisted Pair Fibre optic IEEE 1394 MIL-STD-1553, developed for use in military avionics, it is now widely used in spacecraft too. Adopted for the MiG-35. MIL-STD-1773, roughly MIL-STD-1553 with optic cabling Power-line communication Connectors OBD-2 (16 pin) Additionally, many major car manufacturers use their own proprietary vehicle bus standards, or overlay proprietary messages over open protocols such as CAN. J1939 (9 pin) Commercial class vehicles have Type-I or Type-II connectors that support CAN based communication per the SAE J1939 protocol.
