If you are wondering why nobody replied to your post after 2 days it is because you have not provided enough information and you did not ask a specific question.

Explain exactly what you are trying to do. Describe the process or application. Provide background information that might be helpful such as the industry or location. If it's a school project then just say so.

If you want general information about a device then look the information up in books or search the internet before posting.
