I bought this DAS smart calculator from uobdii.com for some days, when I use 2014.12 software, it always appeared the error message: The entered code number is incorrect.
I have searched on the net and forum for solution but nothing found, finally I asked uobdii engineer for help, they offer me the solution, it work fine then, I would like to share with you, hope to help you.
Solution:
If the DAS is after 2013, you should Copy the [csdsmart.dll] file to F:\Programme\DAS\smar
Download [csdsmart.dll] in the following link:
