Technoton Crocodile Contactless CAN J1939 Reader – Safe Bus Data

Technoton Crocodile Contactless CAN J1939 Reader (CANCrocodile) is a specialized interface designed for the safe and reliable acquisition of data from a vehicle’s CAN bus. Engineered for seamless integration into vehicle telematics and GPS tracking systems, this device enables the reception of critical operational parameters—such as speed, RPM, oil pressure, and fuel consumption—without requiring direct physical connection to the wires.

Description

Technoton Crocodile Contactless CAN J1939 Reader addresses the critical challenge of accessing vehicle data without compromising the integrity of onboard electronics. Unlike traditional methods that require wire splicing, this device employs contactless technology to read data without any electrical connection. This ensures that the CAN wires remain undamaged and the vehicle’s warranty is preserved.

Passive “Listen-Only” Technology

Safety is the core design principle of the CANCrocodile. It operates strictly in a “listen” mode, meaning it passively captures data streams without transmitting any signals back to the CANbus. It does not alter original J1939 messages, ensuring that the vehicle’s control units operate without interference while the telematics system receives accurate, real-time data.
