Re: Freematics Emulator signal only when OBDLink EX attached

The voltage supply detail is useful information, but not relevant to my other feedback / questions, which remain pending moderator approval. I also had previously sent private messages and have received no response.

Re: Freematics Emulator signal only when OBDLink EX attached

It is only when connected to an OBD diagnostic scanner that is actively scanning, and not when connected to an OBD monitoring device that the Freematics Emulator generates a CAN signal. This is not realistic for most cars, where we should expect to see signal activity on CAN when passively listening...

Hi Freematics, I've found that my Freematics Emulator has no detectable signal on CAN, unless it is connected to an OBDLink EX, and then only when the OBDLink EX is in 'connected' mode with its OBDWiz GUI application. When this is the case, I measure 20mV between CAN_H and CAN_L, and can read CAN tr...
