Sniffing the Rigol's internal I2C bus

If you had read the topic you would know. They use the same FW and neslekkim has already successfully hacked his DS2202A-S.

I substituted "0x1C0C7" for "NS8H" and got the identical invalid license. However, I have used the same command with the NSEQ argument to generate a license for "200 MHz, all options" and that key works as it should. Can anyone help me to figure out the problem?
Thanks,

I have the same problem,You solve the problem?
the rigup license keyfile.txt 0x1C0C7(NS8H) key that was generated was rejected by the scope with the message "License is unavailable!".
the rigup license keyfile.txt 0x1C097(NSEQ) argument to generate a license for "200 MHz, all options" is OK.
I was DS2102A

I'm guessing you used the firmware that uses the non-A version key algorithm? There are two versions of keying that can be used. They both work, but I focused on the "A" version so the rigup command I used was different.
I also had to modify the rigup source to have it display the NS8H key. The information on that is on page 195 I believe.

I use the new version of the A firmware,the Rigup license keyfile.txt 0x1C097 (NSEQ) is normal work of the.
I have reference corax articles change the NSFH code to NS8H on line 21 of luxury.c.But no effect under my Windows 7 64 bit
NYG:
That's interesting. I'm using the "A" code, but I ran ./rigup ds2072a mykeyfile .
After doing that it just listed the keys for me. The NS8H key installed without a problem.
BTW I used Linux to modify/run rigup but I would expect the same results in windows.
