Autodata Link

The Autodata Link is a product designed, manufactured and distributed by Photo-Tron Corporation. The Autodata Link was developed in response to our automotive customers' requests for a simple and robust device that would allow various test and automotive analyzers to monitor and log data that is available from a vehicles on-board computer. Prior solutions required special hardware interface modules, a laptop computer and special software requiring significant set-up and training. The other solutions were bulky, cumbersome and sensitive. Frequent lock ups require test to be repeated and cause project delays.

Our Autodata Link OBD2 interface is a compact, robust, plug and play solution. The Autodata Link continuously communicates with the vehicle computer via the OBD2 protocol to track various parameters such as engine temperature, RPM, vehicle speed, throttle position, intake air temperature and more. The Autodata Link then converts the parameters to an analog voltage and variable frequency that is made available on a pluggable terminal block. Up to 4 different parameters can be simultaneously tracked and connected to various types of monitoring equipment.

Key Benefits

  • No set-up: Simply plug in the OBD2 connector to the vehicle computer and the power plug to the cigarette lighter and connect the analyzer equipment to the pluggable terminal block. No operating system to boot up, application start up or configuration.
  • Pre programmed: 4 factory configured outputs can be ordered from a list of over 25 functions that are available from the vehicle on-board computer. Each unit comes pre-configured and ready for your application.
  • Multiple outputs: Each output function is available in an analog (0-5v) voltage or (0-500hz) variable frequency signal format for compatibility with most test/analyzer equipment.
  • Reliability: Embedded micro controller operates reliably and automatically in field environments without the problems inherent with PC hard drives, operating systems and ram based software.
  • Compact: The compact unit is about the size of a cigarette pack and is easily positioned out of the way so you can focus on the monitoring equipment and task at hand.
  • Economy: The is an economical alternative to the other PC, software and special hardware systems.
