Characteristics and applications of DB15 to 9-pin J1939 and 6-pin J1708 splitter Y cables

DB15 to 9-pin J1939 and 6-pin J1708 splitter Y cables are cables used to connect different interfaces for specific communication functions. The following is a detailed introduction for you:

Interface Configuration

DB15 public connector: used as the main connection terminal to connect devices with DB15 interfaces, such as certain diagnostic tools or main control devices.

9-pin J1939 interface: J1939 is a commonly used CAN bus communication protocol standard in the commercial vehicle field. This interface is used to connect devices that support the J1939 protocol, such as commercial vehicle engine control units (ECUs), transmission control units, etc., to achieve vehicle data transmission and communication.

6-pin J1708 interface: J1708 is another communication protocol interface used in commercial vehicles, which can connect devices that support the J1708 protocol, such as some old vehicle diagnostic equipment or specific onboard sensors.

Specific application:

Commercial vehicle diagnosis and data collection: During the maintenance and diagnosis process of commercial vehicles, technicians need to simultaneously connect devices that support J1939 and J1708 protocols. The DB15 male connector diagnostic tool of this cable is connected to the vehicle's J1939 network through a 9-pin J1939 interface, and to devices that support the J1708 protocol through a 6-pin J1708 interface, achieving multi protocol communication.

Vehicle communication and data transmission: In the vehicle communication system, this cable can be used to divert the J1939 and J1708 signals of the vehicle ECU to different monitoring or recording devices, facilitating real-time monitoring of the vehicle's operating status and data collection.

Industrial equipment compatibility extension: In the industrial field, some older devices may only support J1708 protocol, while new devices typically use J1939 protocol. This cable can be used to connect old and new devices, achieve protocol conversion and data sharing, and improve system compatibility and scalability.
