Is this what you're looking for? A simple wired USB to OBD2 interface cable with no Bluetooth or WiFi? I have one I purchased at the same time as Scan XL Pro for Windows. Not sure if it is Elm327 or not. I'm thinking not, because of size of plug would eliminate the necessary electronics you always seem to see.

Wish I knew what all the Acronyms met.
Think I'll get as it looks exactly the same as the one listed in the article and will get here before I start classes. Gonna look over the others tonight and see which looks the best.
Thanks.
Just needed something to convert voltage into bytes and vice versa. I want to do the programming of the software myself.

FYI I have previously typed Hexadecimal code (I found in another forum) into a terminal in Scan XL Pro and effectively communicated with my TCCM on the data bus using the OBDLink-SX. There is a thread on this site about it. This (and the apparent absence of internal electronics) is why I wonder if the OBDLink-SX is different. I could never get a terminal on Android to work with a Bluetooth Elm device for the exact same commands. I always assumed it was because the ELM device didn't understand what I was sending it.
But I admit I really only know enough about this to be dangerous.
In any case good luck

My very limited understanding was that the pins were analog and your hexadecimal stream was digital therefore the elm327 acted as a translator and nothing more. Shouldn't you be able to send any hexadecimal code to the OBD2 through the elm327 and receive the corresponding response?
I could very well have this wrong as programming is my expertise, not hardware or cars.
