Thread: Getting avt852 box working with dhp

I do know that unlocking other Vinson was software related

It seems DHP must have done something with these units once they received them from AVT to give the ability to register in the application.

Did you mess with the baud rate settings in DHP to make sure that's not the problem? If the baud rate is wrong in DHP, it won't communicate. The baud rate that works in the hex editor will be the one that works with the AVT adapter (I'm basing this on how every other serial device I've ever worked with has behaved).

Yes i equalled out my baud rates running in both of dhps available settings in multiple com ports all matched up. Im trying something different. Will keep updated.

Ok AVT boxes had to be setup to match DHP software. Kind of like a password checksum or some such crap. Thus making AVT sold boxes in operative with DHP software unless configured as such. Guy who ran DHP has said not to do it anymore. I he doesn't have permission to make new boxes just repair old ones. I'm sure if tech savvy person out there had two side by side it would be easy but possibly not exactly legal. And considering the software is barely supported/accessible, who should care, as the serviceability of working on these cars is waning as numbers dwindle. I picked up used serial box and am hoping for some luck. But repair is only $40+shipping. So I am hopeful mine is good to go. Someone somewhere was familiar with drones or rc stuff and figured out how to add usb to a serial box. But good luck to all who venture forth.
