Rigol DP832 - Firmware list and bugs

[TurboTom]

There seems to be a new firmware for the DP800 series of PSUs available on Rigol's Chinese web site. Apparently, it's a 00.01.18.00.00 version, released in october 2021. I tried to install it on my DP832 but my PSU refused to work afterwards (initialization appears to work but instrument gets stuck after entry into "operation mode"). Attempting to flash the analog boards didn't show any reaction. Since the file name is "DP800(ARM)update_tcm4-4006.zip", maybe it's meant for a later H/W version of the PSU? Does anybody know what's going on here? Unfortunately, a changelog isn't included in the archive...

I just bought an 832A, and the firmware version from the factory is 00.01.19.00.00.  I couldn't find any release notes as to what this version includes/fixes.  Does anyone have any idea?

I just tried downloading the firmware from the official website (link in post 1). I still got 1.16. What happens if you go to the website and download, will they send you 1.16 or >=1.19? That would indicate some new hardware?

Hi,
new DP832 is also delivered with version 1.19. There is issue with Display settings ... menu items "Contrast", "RGBLum" and "Theme" are missing ...
All other features seem to be OK.

I updated my device from 1.16.0 to 1.19.0 (for what??? ). The update was successful. But after that, all calibration was completely reset.
It was not possible to manually calibrate the device because all the calibrate points values (voltages and currents) were reset. There were just zeros everywhere.

Fortunately, the device was brought back to life and calibrated using SCPI-commands. First, I recorded all the calibration points for all channels according to VDAC, IDAC, VADC, IADC, then  manually calibrated all the channels.

Do not update old devices to 1.19.0. Provide yourself with an activity for a couple of hours (restoring calibration), there will be no further benefit from this

The automatic translation of the chinese changelog looks like this:

Code: [Select]

v00.01.19.00.00 2022-07-20

     - The software increases compatibility with new and old screens;

v00.01.16.00.01
2017-12-18
     
     - The simulation board software is changed to version 02.04

v00.01.16.00.00
2017-01-06
     
     - Fixed the problem that GPIB cannot communicate
     - Modified the problem of command *OPT? returning wrong result

v00.01.15.00.02
2016-05-25
     
     - Modified the storage location of calibration points to solve the problem of missing calibration points. If you directly upgrade this version from the previous version, you need to recalibrate.
     - Added interval monitoring function in the monitor
     - Solved the problem that when the OCP is turned on when the current is small, the current is within the normal range, but the 'over-current protection' prompt will appear
     - Added DP812 model support
     - Modify the OUTP:TRAC? command timeout problem reported by the front end

v00.01.14.00.03
2015-03-10

     - Modify the BUG where OVP and OCP lower limits are displayed incorrectly
     - Added support for DP831, DP811, DP811
     - Added OVP Trip function for new version of DP811A hardware
     - Added series and parallel help information to the main help

v00.01.13.00.01
2014-11-18

     - When modifying the dial display, the pointer is always displayed on the 0 scale BUG
     - Replace the USB Device library: Solve the problem of unstable USB Device communication (picking the line, picking the computer)

v00.01.12.00.00
2014-9-27

     - Added Russian menu
     - Added support for DP812A
     - Modified the display mode of the readback value on the main interface when the DP821A Timer is turned on.

v00.01.11.00.00
2014-11-03

     - Added Traditional Chinese menu
     - The maximum number of recording points for the extended recorder is 614400
So, apparently, Rigol had to change the screens during the production period (probably due to availability issues) and adapted the software for compatibility. There's no indication towards calibration problems, this is mentioned for F/V 01.15.00.02, but that's long past. So your findings are somewhat peculiar. But thanks for mentioning and good you've been able to sort your PSU calibration again...

Having translated the update instructions from Chinese, I realized that most likely I myself was to blame for what happened.
After installing the new firmware, I did not press HELP-HELP-M4-M2-M1  and HELP-HELP-M4-M2-M2 for the analog boards update and immediately rebooted the device with the power button.
Perhaps this was the reason for the calibration reset

My Rigol dp832 now runs digital version 1.14.00.3 analog version 02.02.04 and boot version 1.09.
Here on the forum I see several people with more modern versions but when I look at rigol Europe they only have my current version.
Where can I get a more advanced version? Would it be an idea to make a repository of these firmwares somewhere?

With the current version I have problems communicating over LAN, after a while it locks up and LAN gives no more response, until reboot. While communicating with Labview over USB some response does not work and the example does not work. The Labview example works partly over lan.
So I hope these problems are solved in a newer version.

edit: Ohh stupid me, I looked at the eu store for the update. at rigol.eu there is 1.19 update. Still it would be nice to have a repository of the different firmwares.

I live by the motto "If it's not broken, don't fix it". If your DP832 is doing everything you want as you want, then why upgrade the firmware? It might fix a bug for a situation that you never need, but might also change or break something you do need.
