Hi freaks

I want to find the 16-bit generetor polynomial used to compute the crc of some data. I tried a few common ones (correctly I hope) but dont seem to get anything.

Sample data is:

header + data crc ?!?

7D7523210408206CF0F1390A 61AD

7D7523220408206CF0F1390A 57B6

7D7523230408206CF0F1390A 4DBF

7D7523240408206CF0F1390A 43C8

7D7523250408206CF0F1390A 39D1

7D7523260408206CF0F1390A 2FDA

7D7523270408206CF0F1390A 25E3

7D7523280408206CF0F1390A 1BEC

I chose very similar data packets of the same length in the hope that it will make it easier.

Its possible that a final XOR is performed on the data...

Are there any other types of "checksums" that are not CRC but have the same function?

Thanks for any help you can provide

Regards
