Briefly introduce the structural characteristics and applications of J1939 splitter Y cable

J1939 splitter Y cable is a type of cable used in J1939 protocol networks, mainly for communication connections between electronic control units (ECUs) in commercial vehicles and engineering machinery.

Structural characteristics: J1939 splitter Y cable usually adopts shielded twisted pair structure to reduce electromagnetic interference and ensure the stability of signal transmission. It has a common terminal and two branch terminals, distributed in a Y-shape. The common terminal is generally used to connect to the main bus, while the two branch terminals can be connected to different devices or subnets.

Electrical characteristics: According to the J1939 standard, the bus impedance is 120 Ω.

Function and Function: The J1939 splitter Y cable is mainly used to achieve signal splitting and transmission in the J1939 network. It can distribute signals on the main bus to two different branch lines, or merge signals from two branch lines onto the main bus, facilitating the connection of multiple ECU devices, expanding network nodes, and achieving reliable communication between devices.

Application scenarios: Widely used in the field of commercial vehicles, such as trucks, buses, as well as engineering machinery, agricultural machinery and other equipment, used to connect various electronic control units such as engine controllers, transmission controllers, ABS controllers, instrument panels, etc., to achieve data exchange and communication control between them.
