Sniffing the Rigol's internal I2C bus

[H.O]

Hi,
Yes, I'm pretty sure you should be able to trig on a specific byte/char, both on the DS2000 (might be an option) and on the DS4000 but again, seeing how slow the decoder is I might have misunderstood it completely....

Take a look at page 5-35 in this DS2000 user guide.

Ah, I see. Must have skipped that part of the page. I think there's still hope, because the trigger and the decode are different functions.
The RS232 trigger is standard available, and to make it work it must be implemented in hardware. The RS232 decode is an option and by looking at the speed it is implemented in software.

anyone with a DSA around and willing to test some keys ? ... pm me

I have a DSA815-TG. What keys do you have for me?

[cybernet]

i dont know ;-) i dont have a DSA, but i believe the i have found the private key for it so i could generate keys, other than option 1 (which i was told is the TG) - pm me with serial if u are willing to try.

I'll message you with the serial number as soon as I get back to my desk. I'm assuming this shouldn't de-activate that option 1? I like my tracking generator

Is this a model change, or just activation of the add-ons?

[cybernet]

i dont know because i dont have a DSA - im working from a memory dump - no guarantees, it might blow up or whatever ;-)
no risc no fun.

somebody took the risk - and has now fun ;-) thanks to the tester !

Wow, you guys are great. I don't have a SA and I don't really have a need for one but never the less, I'm impressed! Is anyone looking further into the possibillity of unlocking the BW on the DS4000 series?

WOW 

[olsenn]

Cybernet: I sent you a PM with my serial number

[olsenn]

Son of a bitch! IT WORKS!!!! I have 10Hz RBW now. I haven't tested the others yet

Release your work cybernet... you are the man!

[dr.diesel]

Release your work cybernet... you are the man!

Agreed,

815 powered up and waiting!

[Marc M.]

Cybernet is the MAN


10 Hz RBW!!!     (10 Mhz Sine output from DG4162 @ 400 mVpp)


VSWR Enabled!!!


AMK Enabled !!!!


It's Official!!!!

And it sticks after power cycling.

enjoy

would not have happend without jtag firmware dump from DL5TOR, ecc help from some guy and testing by marc - thanks guys.


PS: the windows tool makers, might want to integrate that into their tool - only the length of the serial & private key differ, rest is the same ! (RILOL !)

It would not have happened without:
The jtag firmware dump from DL5TOR
ecc help from some guy
Coding by Cybernet
Testing by Marc M.

I find it very selfless to release all your work for everyone to freely use. Good on all of you 

[olsenn]

Now let's just see how long before Rigol is forced to release the 10Hz add-on for sale, haha

Since this option isn't available outside of China, I'm also wondering what their reaction is going to be.  They certainly won't be very happy about this  .

[tom66]

Is the method similar for DS2000? Has that been broken already?

[dr.diesel]

WooHoo!

Note, for whatever reason compiling this on my Fedora 19 box truncates one character on all 3 variables, not sure why.  Anyhow, Mint 15 worked great.

Thanks again to all involved.

Serves them right quite frankly

I wonder what impact the recent success in hacking the protection schema will have on hardware manufacturers deliberately crippling their products for residual sales. Will they strive to further harden their licensing schemes? Or will they abandon the "pay-for-addons" model realizing that the license scheme will be hacked at some point.

To be fair, most of the people (I imagine) who would have purchased any of these add-ons, still will even though there is an illegal crack available. I think this thread is mostly for us hobbyists who stick to the free-or-nothing model

Agreed, the number of people that find this thread, manage to get it compiled and working are not even a blip on the screen for Rigol.  In-fact, for me, it's a reason to keep buying Rigol equipment, which I'll do unless they get real cranky and mess up our fun.

^^ This. I would have just kept "saving" and ordered an Agilent or something if the DS2072 wasn't hackable. :-)
