The main diagnostic tool is not capable of auto-selecting the OBD lines. This box allows you to manually select the proper communication lines. In other words - a manual hand operated multiplexer.
Even though the exterior case, buttons, and display look the same as the RR tool, I have been told that there is not enough memory to convert it to RR. This is what I have been told. Please inform us otherwise.
Yep, I thought that it might be some sort of break out box. The scanner works fine. I expect that the hardware is used by different manufacturers and the programming is different. I don't buy that OTC or any other hardware mfg will make something unique in small #'s for RR and Bentley.
