Converting OBDII data to J1939 requires more than just a simple cable; it necessitates a device capable of processing and translating the data due to significant differences in protocols, data points, and calculation methods. J1939 and J1708, while both used in heavy-duty vehicles, also have distinct data structures.
Several solutions exist for accessing and converting this data. For instance, SilverLeaf Electronics offers the VMSpc, a device that reads J1708 data and displays it on a Windows tablet. While a useful tool priced around $400, it may lack certain desired parameters. Alternatively, the ScanGauge D provides a more budget-friendly option for basic data retrieval and display.
For those with programming skills, a J1708 to serial converter coupled with a Raspberry Pi and a touchscreen offers a customizable solution. Using languages like Python or PHP, users can create tailored software for displaying the converted data. This allows for a highly personalized setup, displaying precisely the information needed. The complexity of this approach depends on the user’s technical proficiency.
Ultimately, choosing the right Obdii To J1939 Converter depends on individual needs and technical capabilities. From pre-built devices to DIY solutions, various options cater to different budgets and levels of expertise.
