New Rigol 16-bit function generators DG800/900 series

[Frex]

Hello,
Ok, thanks for clarifying.
(And my apologize about ECDSA misunderstanding).

So, now we must wait that someone explain how to get same "trick" as on the Ashdash device,
 or if firmware downgrade is possible to get it.  That's it ?
Best regards.

@Frex: Or you can offer to volunteer testing the experimental downgrade firmware file that TV84 may provide on your DG800. This will (most likely) result in an improved machine for you and a path for others to follow who are in the same situation as you are now.

[Frex]

@TurboTom: Yes of course, but i don't have own it yet,
i wait for the trick become available before deciding to buy it .

No it should be FAT32, I would recommend finding an older smaller USB key if you have one but that might work.
- Download HxD, run the program, select Tools -> Open Disk -> uncheck "open as readonly" at the bottom -> Select the USB drive (make sure it says Removable Disk as type) and click OK
- At the top where it says Sector, enter 2000000 and press enter
- Copy the magic bytes from tv84's sardinha bin file (0B0A3B2E5F4CECBE), on the top select Edit and then "Paste write"
- Click Save
- Eject USB key
- Plug USB key into back of instrument, it will show the USB symbol in the top right if its detected. You can see if the drive can be opened in the DG800 menu if you like as well, but it won't indicate if it is the magic key or not.

You can send SCPI commands with USB on the back port yes, or ethernet with adapter.

Thanks to tv84 for the original post and to you for posting this. 

I had some trouble with the original instructions (definitely PEBKAC, I am very out of practice with Linux) and your directions showed me where I was going wrong.

For non-Linux types: you can do this in windows 7 with rigol's ultrasigma SCPI control program over USB and, as noted above, make the key following these directions. No ethernet adapter necessary nor Linux expertise! 

BTW... I am using a Plugable USB to ethernet adapter (USB2-E100) with no problems. About ten bucks I think.

My two cents: I tried literally every possible way of preparing flash disk using windows. Did not fork for me. Solution was Linux (rPI) to prepare - format & write flash, then windows ultrasigma software.

I had exactly the opposite experience trying to format the drive in Linux. In my case, I am sure it involved a large PEBKAC factor so after three or four tries, I stuck the USB stick into a windows 7 box, formatted it to FAT32 using the standard format tool, opened HxD, inserted the key bytes, saved it and was good to go. 

Reality is very odd sometimes.

But downgrade can also be a easier way. All I need is a volunteer.

The volunteer has appeared and helped test the downgrade FW.

So, now there is a FW v1.08 that can be flashed over a v1.09. It has been successfully tested.

The following can also happen immediately:
Additional PRO: immediately converts the unit to DG992, with no more commands.   
Additional CON: resets the S/N. So, one must resend the S/N with the SCPI command :PROJ:SN.

nice piece of work! 

[bitseeker]

Agreed. Well done, tv84!

[Frex]

Hello,
indeed very nice TV84 !   
How to perform this then ?
Can you explain a procedure ?

Frex

[tv84]

Can you explain a procedure ?

Upgrade FW procedure as usual.

[Frex]

 
Ah ok ! 
I wasn't thinking that is so simple...
So as soon firmware is back to 00.01.08.00.01 , we can follow the procedure
in you post #147  , it is correct ?
Can i use the old (01.08) firmware here ?

I downloaded the firmware zip file I linked above, and it include
a GEL file and text file.

When i open the text file "DG800_DG900 Upgrade Instructions.txt" i can read :
"  - DG800/900 series digital oscilloscope does not support the downgrading
      operations. "

What about this , It's a lie ?

I crafted the downgradable version.

Frex, the patched firmware was never posted by TV84.

If you try to install the official firmware, of course it's not going to work since Rigol do not support downgrade.

[Frex]

OK I see.
Sorry once again for the misunderstanding.
So it isn't as simple and we need this new 01.08 "custom"  firmware
before to try downgrade.
Do you share it TV84 ?

Frex, now it's my turn: have you got the equipment? If not, then you don't need the file.

[Frex]

Not yet, well done. 
But i could ask you when done ?

Hello,

I received today my DG811 from Batronix !
Good news, it is arrived with the old firmware 00.01.08.00.01
I have made the special USB key.
To send the SCPI command, does the easiest way is to
install RIGOL UltraSigma software ?
Regards

Frex

[egonotto]

Hello,

no, Peter Dreisiebner Rigol Bildschirmkopie LAN/USB is much better. http://peter.dreisiebner.at/rigol-bildschirmkopie/index.htm

If you use lan you dont need a installation.

Best regards

Ok right.

I installed it, but when i tried to install the WinUSB driver (WinUSB (v6.1.7600.16385))
 with Zadig the install fail . I'm on win7-64.
Any idea ?

Frex

[Frex]

Hello,

After installing Rigol Bildschirmkopie LAN/USB and WinUSB drivers with Zadig,
the DG811 recognized but communication not work (error when scpi command send).
SO i finally install Rigol UltraSigma that is a nightmare on win7...
Anyway, now the DG811 is becomed a DG992 !
Very happy, and big thank to all ! (special for TV84).
Regards

A HUGE thanks to tv84 for helping me with my DG812->DG992 upgrade!

I've written up a set of instructions based on tv84's original instructions, but also added a few bits gleaned from other discussions and my own adventures and missteps while performing the upgrade. I have not tried the upgrade method for firmware 01.09, so the command I've listed for that upgrade is based only on what I've read in this forum. I would definitely appreciate any comments, suggestions, additions, or corrections to what I've written here.


HOW TO CHANGE RIGOL DG800/DG900 MODELS

1. Format a blank USB disk of at least 1GB capacity as a FAT32 drive

2. Write the special signature to the USB disk (assuming it is at /dev/sda1) with the following Linux command:

   sudo dd if=DG800_sardinha.bin of=/dev/sda1 bs=512 seek=2000000

Or use the HxD program in Windows to write the following 8 bytes at offset 2000000:

   0B0A3B2E5F4CECBE

3. With the special USB disk inserted, send the SCPI command via the DG USB interface (using Rigol Ultra Sigma, for example) to change the model to DG992:

   :PROJ:MODE DG992      (for firmware 00.01.08.00.01 or lower)

   :PROJ:MODIF DG992   (for firmware 00.01.09.00.00 or greater)

DO NOT use the "Send and Read" command. Attempting to read a response from the DG will invalidate the command.

Possible model types (as seen in the first 4 bytes of the sd.xx configuration file):

00 - DG811
01 - DG821
02 - DG831
03 - DG812
04 - DG822
05 - DG832
06 - DG952
07 - DG972
08 - DG992

4. Remove the special USB disk from the DG and restart the DG.

5. Enjoy!

[tv84]

:PROJ:MODIF DG992   (for firmware 00.01.09.00.00 or greater)

This is not correct! The rest is OK.

MODIF command is something like this:

PROJ:MODIF DG992,<---512 bytes block with encrypted signature of the model--->

[swperk]

Thanks for that correction!

Do you know if the purpose of the 01.09 release was only to close the window for the upgrade possible under 01.08, or were there additional features enabled? I notice that on www.rigolna.com, the latest firmware is still shown as 00.01.08.00.01.
