I'm well aware I can activate all the features with your FRAM changes, but that only unlocks it for me - generating serials solves it for everyone. |

The DP700 keygen is identical to the DL3000 keygen (with a different char_map). See here. They don't use ECC as riglol/rigup. It's a cascade of CRC16 calculations giving a 28-char license. The only parameter that is needed for the calculations is the S/N. I've successfully licensed a DP711 (attached). Example of licenses for someone curious: Rigol DP700 S/N: DP7A123456789 Official License DP7-TRIGER 22W5NBYPM6GUP27A68RY4VWQWH5L DP7-TIMER T9ZKK8GPH7GUTA2BUDDYWJX8PKJ5 DP7-HIRES AES6FY3KV6GUV4ENR6QCBK8HH2CK |

Good afternoon! Tell me, how exactly did you generate the keys for dp700? Did you do it with riglol? What keys should I use? |

Hi, I would also be interested to know and understand how the calculation using this cascaded CRC-16s works. If I understand this procedure correctly, a CRC-16 is applied to each character of the S/N and converted back to characters via a mapping table? |

I will not make the method public. But it's easily visible in the DL3000 FW for those who know how to see. |
