Are you trying to run the Auterra Dyno-Scan software for Palm (Auterra part number S-100) with an Elm327 device such as the ElmScan 5 or the OBD2 All-In-One scan tools?
Auterra states that their software is designed for use only on their products, such as the A-300, A-301, or A302.
The Auterra hardware is different from the ElmScan and All-In-One unit and is not based on the Elm327 IC. Therefore I do not believe you'll be able to get Auterra software to work with an Elm device.
We usually recommend PCMSCAN software as the best OBD2 scan tool and data logging software and it runs very well on the ElmScan and All-In-One units.
I hope this has been helpful, but please keep posting if we can assist in any way.
