Hi Andy,



((("No, this data sheet is for checksum."

Which one?)))

You are right to ask this question.
I wanted to replay to Chris Brooks that posted this mail with an attached web address:

///*
well, ok, I'll believe you :-)
Here is how to do a CRC, if you need to implement a specific type of CRC the datasheet should be able to tell you how to do it.

As I usually read carefully the daily mail, kindly sent to me by the moderator of this forum, I accessed this page and I sow it was a misunderstanding so I replayed to Chris.
The page is for checksum not for CRC.
Please try it you self and tell me if I was right or wrong.

It was my mistake to replay to a mail without mentioning the addressee.
As my Internet connection is not very good I use to click to the mail address in the Message Link sinking it works like the replay function in Outlook Express.
I was wrong.
In the future I promises to pay attention to this.

Regards,
Cristian
