Need help hacking DP832 for multicolour option.

[Trident900fi]

hi folks,

I've just calibrate the channel 1 without problem.
Than I try to calibrate channel 2, but there is no more voltage going out from channel 2 and 3 now !
You can ask whatever you wont, you always get 0V...
Any idea !?

If we are talking about DP832, simply select the desired channel with the select button ("1", "2" or "3"), turn it on and enter the calibration mode.

Since I've calibrate the channel 1, there is no more any voltage going out of channel 2 and 3...
So when you run the calibration, it always mesure near 0V.
That's my problem.

Good day, Experts.
Please help me with the following questions
I have an Power Supply Rigol DP832 converted to an Power SupplyRigol DP832A using the method mentioned in this topic
After the modification, I got the available options LAN, RS232, color display
Communication with the device on the network through the LAN interface is successful using software ULTRA SIGMA from the manufacturer

Communication of the device with the computer through PC232 is not established (Reaction is absent)
The scheme of connection is used: Computer with RS232 port-Cable RS232 (9 pins) - Power Supply Rigol DP832(A)

The RS232 cable has the following scheme of contact pins 1-1, 2-2, 3-3, ..., 9-9

Communication of computer <-> other measuring device (not Rigol) using this RS232 cable is normal

Questions:
1) What type of RS232 cable should I have (1- ?, 2- ?, 3 -?, ... 9-?)
2) What RS232 cable lines are really needed to control the Rigol DP832A) and receive/transmit data from/to it ?
3) Do I need to make any settings directly on the device?
4) Does the device have any specific parameters of communication with the computer on RS232 ?

P.S. Sorry for typo: Oscilloscope - Power Supply. Post corrected

[RoGeorge]

DP832 is not an oscilloscope, and whoever orders one most probably will know the difference.  It can be hardly be mistaken that way.

Are you a bot?  Yes or no?
Prove it.

User manual page2-56 explains pinout and settings including flow cotroll.

Sorry for typo: Oscilloscope - Power Supply. Post corrected. I am now very focused on oscilloscope programming and therefore all thoughts about oscilloscope

[RoGeorge]

Without opening the manual, I will first try pin 2 to 3 and 3 to 2, aka Tx to Rx and Rx to Tx (and GND, of course).  So only 3 wires.

Usually the settings would be 9600, 8, N, 1, the most common default RS232 setting (but I don't have the manual right now, so better look up the DP832 user guide/manual).

To update your Rigol DL3021 to DL3021A, here is the complete procedure, without the need of buying the LAN option...
You need:
-Computer with RS232 port
-USB stick formatted in FAT32 with the file keyfile.bin from Tossu (many thanks for the hack !)
-Cross cabel RS232 female-female (2->3; 3->2; 5->5)
-Free software Termite from Compuphase (https://www.compuphase.com/software_termite.htm)

Connect everything together. Start the computer first and launch Termite.
Termite Serial port settings:
-Port COM1 (depend on your computer)
-Baud rate 9600
-Data bits 8
-Stop bits 1
-Parity none
-Flow control none
-Forward none
-Transmitted text Append CR-LF

Turn on the DL3021
To check the connection, you can try to type *IDN? in the Termite command line.
He will return the model of your device.
Type in Termite :PROJ:SET MODEL,DL3021A
That all 

Hello friends

In 2021 I tried this on my new DL3021, with no success.  SW version is 00.01.05.00.01. RS232 works well. Command "*IDN?" returns product name, serial number and SW version. Command ":PROJ:SET MODEL,DL3021A" does nothing.
Any idea is welcome.
Thanks

I think you need a space after the comma: ":PROJ:SET MODEL, DL3021A"

[natman69]

Hi,

the command is correct! And it is normal you don't get any reply after you send it. Only after a reboot you can see the model has changed.

Are you sure you build correctly the usb thumb drive? I used win32diskimager and all was smooth...

BTW: I used USB connection to instrument not RS232 and key sight connection expert to send SCPI commands.

Hope this can help!

Hello natman69

Thank you for your response. I installed a keysight connection expert and connected to DL3021 via USB, but the result is the same:

-> *IDN?
<- RIGOL TECHNOLOGIES,DL3021,DL3AXXXXXXXXX,00.01.05.00.01

-> :PROJ:SET MODEL,DL3021A
 ! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)
<-

The same result is for command":PROJ:SET MODEL, DL3021A"
When command had been used, I tried "turn off and on" DL3021 and also tried make intial Reset DL3021, but no change version model to A.

Are you sure the USB stick is recognized by the DL3021? Can you store a file on it using the DL3021?

I remember having an issue with a "space" in the command when I upgraded my signal generator, but natman69 could be correct, that maybe I added the space as per some posts in this forum, and it should be removed, so your initial command was indeed correct.

Thank you very much for your help. It really was my fault - a badly prepared USB key. Now I can confirm the hack is also possible with this latest firmware.
Everything is OK. The Keysight connection expert immediately set new product name to A and switched ON colour displey.

Status from The Keysight connection expert:

-> :PROJ:SET MODEL,DL3021A
<- OK

Now it's a really great device 
 
Thanks again for big support, I wish you all good health in this post covid time and have a nice day.

Hello friends ， need help…

Using this method, success.  (FW:00.01.05.00.01)

However, about one minute after power on, the high-resolution disappears automatically.

The option function also disappears   （color UI is still there）

What model number does your unit return when you send -> *IDN?

I do not have a Rigol load, but if I am not mistaken, the color display is always enabled and there is no change when upgrading from a DL3021 to an DL3021A. Did you see the increased readback resolution on the display briefly? Can you make a picture of that? My best guess currently is the patch was not applied correctly and nothing was changed and it did not disappear automatically...

Wow, that is indeed strange! Maybe try to manually set the model number to the original first (:PROJ:SET MODEL,DL3021), power the unit completely down an up again and start over from the beginning? Probably will not make a difference, but I cannot think of anything else (maybe downgrade the firmware, but that could maybe be risky on its own).

Does your unit maintain other settings like for example its IP address, or is everything reset to default values when it happens?

[ee2000]

Hi

I just wanted to ask if there are any update on the matter, did you succeed in turning the DL3021 into and DL3021A,
with a permanent solution longer than 1 minute ?

Thanks in advance.

I can confirm this worked on a DL-3021 FW:00.01.05.00.01 with a unit just purchased.

Hello all,

Hoping this isn't the wrong place to ask, as this seems to be discussion around the model change hack, but I just bought and received a secondhand DP832, and immediately updated to the latest firmware.  I then tried to apply the riglol hack (entered my serial number on the page, left the AAAA default options, and it generated a licence key.

However, when i try to install the key at the "licence" prompt, after entering all the characters, I press OK, and it says "Invalid Serial" number.  I have tried twice without success, and even tried regenerating the key on the site several times - it creates the same key every time.  Double checked that my serial number was accurate too...

Am I doing this wrong?  Or is the latest firmware different and no longer allows the licence hack to work?

UPDATE:  I got it to work.  Had to do each option separately - skipped the RS232 since I had read that one doesn't work anymore (which is fine by me, and I didn't plan to use it)...

Now on the the model upgrade! :-)

Hi Mate.
Can you please point me in the right direction for the download link of keyfile.bin from Tossu for the Rigol DL3021A Mod

For those of you using Windows for Magic USB creation, I wrote a simple step-by-step guide for it.
I personally don't own a DP832 yet, but planning on it.

Windows Magic Drive creation

1. Open up your diskpart.exe in Administrative mode
2. Select the disk number of your USB drive.
3. Type clean all and wait.
    - This should take some time, since it is writing zeroes to the blocks.
4. Make partition by typing create partition primary size=1024.
    - The smaller the size, faster the image dump and writing.
    - But keep in mind that the sector 0x58E0 should be included.
5. Finally format the partition by format fs=FAT32 QUICK
6. Dump the USB using any kind of tools, output is binary file.
7. Using HxD or other editor, change the data.
    - If you are not sure which offset should have the *Magic* numbers, the offset should be 0xB1C000 for FAT32.
    - The sector is 0x58E0, which in decimals 22,752th sector.
8. Save the image file to a certain location.
9. Now write the image to the disk using Rufus or BalenaEtcher, etc.
10. Done!
11. https://www.eevblog.com/forum/testgear/need-help-hacking-dp832-for-multicolour-option/msg2320485/#msg2320485

Side note - I added a 100MB Partitioned Dump binary. This should make things easier by skipping the format and partition creation process.
