What are the product features of J1939 to OBD2 cable?

J1939 to OBD2 cable is a key tool for commercial vehicle diagnosis and data acquisition. Its product features are designed around four core requirements: protocol compatibility, structural reliability, functional scalability, and environmental adaptability. The specific characteristics are as follows:

Protocol compatibility: achieving seamless integration between J1939 and OBD2

J1939 protocol support: J1939 is the mainstream communication protocol for commercial vehicles such as trucks, buses, and construction machinery. The cable needs to be fully compatible with the physical layer (such as twisted pair shielding design) and data link layer (such as PGN parameter group number, multi packet transmission protocol) of J1939, ensuring the ability to resolve key parameters such as engine speed, vehicle speed, fuel consumption, and fault codes.

OBD2 protocol adaptation: OBD2 is the standard diagnostic interface for passenger cars and some commercial vehicles. The cable needs to achieve protocol conversion through pin mapping, so that the diagnostic equipment can read J1939 vehicle data through the OBD2 interface.

Certification and Compliance: Ensuring Safety and Compatibility

SAE standard compliance: Strictly follow SAE J1939-11 (physical layer), SAE J1939-21 (data link layer) and other standards to ensure compatibility with mainstream commercial vehicles.

Installation convenience: Simplify maintenance process

Plug and play design: Standard connectors are used at both ends of the cable, eliminating the need for welding or modification, allowing maintenance personnel to quickly deploy.

Cable length customization: Provides multiple length options to meet different installation space requirements.
