The KD031 features a unified design integrating power, data, and signal. It directly supplies B+ (constant power), GND (ground), and ACC (ignition signal) to peripherals, reducing installation time significantly. Its precise ACC signal syncs device operation with ignition status, preventing errors like DVR recording after engine shutdown—functionality often missing in similar devices.
The KD031 is one of the few in-vehicle data devices that supports both SAE J1939 (for heavy trucks) and OBDII (for passenger/light commercial vehicles) protocols. This dual-protocol capability eliminates the need for additional converters and simplifies wiring, making it perfect for mixed fleets like logistics companies with both heavy-duty trucks and light vehicles.
Reads CAN data for commercial vehicles supporting both J1939 and OBDII protocols.
Provides power and accurate ACC signals to peripherals (such as DVRs, trackers, etc.), simplifying peripheral installation.
Two serial ports (TTL) are reserved to provide CAN data to peripherals via the serial port or to connect to RFID, sensors, etc.
Supports FOTA and local serial port upgrades.
