This OBD2 to DB9 serial cable provides a simple and reliable interface between a vehicle’s OBD2 diagnostic port and legacy serial communication equipment. Designed for automotive diagnostics, data logging, and firmware updates, it enables direct RS232 communication with PCs, industrial terminals, and diagnostic tools that use a standard 9-pin serial port.
Key Features:
- OBD2 16-Pin Male Connector – Plugs directly into the vehicle’s standardized OBD2 diagnostic socket (compliant with SAE J1962).
- DB9 Female Connector – Connects to RS232 serial ports on computers, data loggers, or diagnostic devices.
- RS232 Level Output – Supports standard serial communication protocols for direct connection to serial interfaces (no built-in level shifting – use with proper interface circuitry or USB-to-serial adapters as needed).
- Durable Construction – Molded connectors and strain-relief boots for extended durability in workshop and field environments.
- Color-Coded or Labeled Wires – Clear identification of OBD2 pins (e.g., +12V, GND, CAN, K‑Line, L‑Line) for custom wiring or troubleshooting when required.
- Compact and Flexible – Cable length is ideally suited for bench testing, in-vehicle diagnostics, and mobile applications.
Typical Applications:
- Vehicle ECU scanning and reprogramming
- OBD2 data acquisition and telemetry
- Legacy diagnostic tool integration
- Automotive research and development
- Education and prototyping
Note:
This cable provides a direct pin-to-pin connection for signal lines. Please verify your device’s serial voltage levels and communication protocol (e.g., ISO 9141, KWP2000, CAN) before use. For certain applications, an external level shifter or interface adapter may be required to match RS232 voltage levels.
