I am trying to figure out the crc used in serial communication

I am trying to figure out the crc/ checksum used in the following data set. Any one any idea

1) 01 03 13 92 00 04 e1 59 0d

2) 01 03 13 93 00 04 61 4e 0d

3) 01 03 1b 68 00 04 5d 12 0d

4) 01 03 1b 5f 00 02 df ad 0d

5) 01 03 13 96开发者_开发技巧 00 04 61 0a 0d

6) 01 03 1f 4b 00 02 46 be 0d

Thanks in advance

You should have provided dataset -> corresponding crc at least. I can suggest to bruteforce all crc-16 polinomials and see if any of them match all your datacases. It's just 65k variants.
