Product overview
The OBDII Odometer is a smart interface cable that communicates with a vehicle’s onboard computer to provide vehicle speed as external aiding for Advanced Navigation INS solutions. The device outputs real-time vehicle speed over an RS232 serial data interface and, when connected to an INS product, allows for improved navigation accuracy when GPS is not available.

Features

• ABS Speed and Reverse Detection: Retrieves very accurate, high resolution vehicle speed from the ABS system on some vehicles. On other vehicles the transmission provides an accurate speed. Some vehicles also offer reversing detection via gearbox position.
• Miniature Durable Design: Miniature in-line design that is easy to fit into any vehicle; features a strong ABS plastic shell and tough strain-relieved cabling.
• Reliability: Built on a safety-based real time operating system with software designed and tested to safety standards. Hardware is designed to MIL specs and has fully galvanically isolated power and communications.
