Interface characteristics of right angle OBD2 to J1939 cable
The interface of the right angle OBD2 to J1939 cable has the following characteristics:
OBD2 interface features
Standardization: The OBD2 interface follows international standards and has unified physical dimensions, pin definitions, and communication protocols. Generally, it has a 16 pin trapezoidal interface, which enables it to be compatible with various vehicles that comply with OBD2 standards, making it convenient for users to diagnose and read data.
Easy to connect: The interface is designed with a right angle and has anti misoperation function. Users can easily connect the OBD2 plug of the cable to the OBD2 port of the vehicle, and the connection is relatively stable and not easy to loosen.
Multifunctionality: Through the OBD2 interface, not only can vehicle fault information be obtained, but real-time data such as engine speed, vehicle speed, coolant temperature, etc. can also be read. It also supports basic diagnosis and configuration functions for some vehicle systems.
J1939 interface features
Suitable for commercial vehicle networks: J1939 interface is mainly used for communication between electronic control units (ECUs) of commercial vehicles (such as trucks, buses, etc.). It adopts CAN (Controller Area Network) bus technology, which can achieve high-speed and reliable data transmission between multiple ECUs to meet the complex control system requirements of commercial vehicles.
Multi pin configuration: J1939 interfaces typically have multiple pins, typically 9 pins. This multi pin configuration can support rich communication functions and device connections, such as connecting multiple sensors, actuators, and other in vehicle electronic devices.
Support for hot plugging: The J1939 interface supports hot plugging function, which means that devices can be safely connected or disconnected during vehicle operation without causing damage to the vehicle's electronic system. This feature facilitates the installation, maintenance, and upgrading of equipment, improving the scalability and flexibility of vehicle electronic systems.
Electrical characteristic matching: The electrical characteristics of J1939 interface match the CAN bus standard, with strong anti-interference ability and signal transmission capability. It can work stably in complex electromagnetic environments, ensuring the accuracy and reliability of data transmission, and adapting to the operational needs of commercial vehicles in various harsh environments.
