  1. Add or change predefined CAN response ids. The default parameter for the response id is “0x7E8”, which is the standard response identi-fication of a standard CAN OBD communication (11 bit). Different ECU’s can communicate with another response id. For a CAN extended communication port use a valid CAN ex-tended response id (e.g. “0x18DAF110”). OBD 2 allows the communication with multiple ECU’s to the same OBD 2 request. For this multiple response ids are allowed (“0x7E8 0x7E9”). A mix of CAN standard and extended re-sponse ids is illegal

  2. Change the request timeout if necessary. This specifies the minimum time span in millisec-onds for requesting different OBD 2 Parameters.

  3. Change the preset frequency if necessary. With this item you can set the frequency of se-lected OBD 2 parameters without a valid frequency attribute loaded from xml file.

  4. Press OK.
