The DynoSure OBD to DB9 Converter provides a universal and reliable connection between your vehicle’s OBD-II port and your USB-to-CAN tools (including the DynoSure SLCANv1, SLCAN GPIO, and LoggerV1). Built to industrial quality standards, it ensures robust communication and seamless power delivery.
💡 Why Did We Build the DynoSure OBD to DB9 Converter?
Many commercial OBD-II to DB9 cables are either prohibitively expensive or use non-standard, proprietary pinouts that do not match standard CAN bus analysis tools. This makes connection and power routing difficult and prone to errors.
We built the DynoSure OBD to DB9 Converter using the industry-standard wiring map. It routes the vehicle’s standard CAN lines and battery power directly to the correct pins on your diagnostic tool, allowing you to connect and power your devices directly from the vehicle’s diagnostic port without additional wiring.
Specifications & Pinout Mapping
The converter is designed for automotive environments, featuring low-resistance copper conductors for signal integrity and durable molded connectors for strain relief.
| DB9 Pin | OBD-II Pin | Signal | Description |
|---|---|---|---|
| Pin 2 | Pin 14 | CAN-L | CAN Low line |
| Pin 3 | Pin 4 & 5 | GND | Chassis and Signal Ground |
| Pin 7 | Pin 6 | CAN-H | CAN High line |
| Pin 9 | Pin 16 | +12V Battery | Power Input (routes vehicle power to LoggerV1) |
Key Features
- Universal Compatibility: Works out of the box with DynoSure SLCANv1, SLCAN GPIO, and LoggerV1, as well as other standard-compliant CAN interfaces.
- Power Delivery: Directly routes OBD Pin 16 (+12V Battery) to DB9 Pin 9 to supply required power to the LoggerV1 in standalone logging mode.
