Structural characteristics of J1939 to RP1226 cable

J1939 to RP1226 cable is a special cable used in the field of vehicle communication and diagnosis. The following is an introduction to it:

summary

Definition: J1939 to RP1226 cable is a type of cable that converts interfaces that comply with the J1939 protocol into RP1226 interfaces. It is mainly used to achieve communication connections and diagnostic functions between different vehicle electronic systems or devices.

J1939: SAE J1939 is a series of standards developed by the Society of Automotive Engineers (SAE) in the United States. Based on CAN bus technology, it is mainly used in commercial vehicles, heavy machinery equipment and other fields to achieve data exchange and collaboration of vehicles and equipment from different manufacturers on the same network.

RP1226： It is an interface standard commonly used for connecting automotive diagnostic equipment with vehicles, providing a unified physical connection and communication specification for vehicle diagnosis and data reading.

Structural characteristics

Interface type: One end is a connector that complies with the J1939 standard, commonly a 9-pin connector, used to connect vehicle electronic control units (ECUs) or other devices that support the J1939 protocol. The other end is the RP1226 interface, which usually has a specific number of pins for connecting with automotive diagnostic tools, programming devices, etc.

Cable material: High quality copper core wires are usually used to ensure good conductivity and signal transmission performance. In order to reduce electromagnetic interference and radio frequency interference, cables may have shielding layers such as braided shielding or aluminum foil shielding, and the outer layer may have wear-resistant, oil resistant, and corrosion-resistant sheath materials such as polyvinyl chloride (PVC), polyurethane (PU), etc.
