Structure and Characteristics of 9 Pin J1939 Green Type 2 Male to J1939 Type 1 Female Cable

Interface conversion

Input end: Green Type 2 9 pin male connector, commonly used for high-speed CAN bus in commercial vehicles such as trucks and buses.

Output end: Type 1 9 pin female head, commonly found in some commercial vehicles or diagnostic equipment.

Function: To achieve physical connection between Green Type 2 interface and Black Type 1 interface, and solve interface compatibility issues between devices or vehicles.

protocol compatibility

Supports SAE J1939 protocol (commercial vehicle standard) without the need for additional protocol conversion, ensuring consistency in data transmission.

structure and characteristics

Physical specifications

Color identification: Green represents Type 2 interface (high-speed CAN), black represents Type 1 interface (low-speed/fault-tolerant CAN).

Connector type: The mating design of male (pin) and female (socket) ensures a stable connection.

Cable material: shielded twisted pair, resistant to electromagnetic interference (EMI); The connector material is high-strength plastic or metal, resistant to vibration and corrosion.

Pin Definition

The 9-pin pin includes power supply (12V/24V), CAN-H/CAN_L, signal ground, etc. (must comply with J1939-11 or J1939-13 standards).
