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  :D

Can hack the DC Load DL3021 to DL3031A?  Like the DG811 to DG992?

Does not the DL3021 hack can be done when connected via USB ? like the same way DP832 ?

I just tested with USB. Though the command was successful, I saw OK message, it does not work and my load model remains the same i.e. DL3021.

Perhaps I have to use the serial /RS232 interface.

Flash the rigol-key.img from the attached zipfile to a USB drive using your prefered disk imaging software. (dd/Win32 Disk Imager)

Power on the device, and insert the thumbdrive

Send the SCPI command to change the model number:

For the DP800 series

--- Code: ---:PROJ:SET MODEL,DP832A
--- End code ---

For the DG1000Z series

--- Code: ---:PROJ:STAT MODEL,DG1062Z
--- End code ---

For the DL3000 series

--- Code: ---:PROJ:SET MODEL,DL3021A
--- End code ---

Reboot the device and you should be done.

Rigol's Ultra Sigma and the IVI drivers it provides have always been very flaky for me, so I used Messinstrumente with Zadig USB drivers

http://peter.dreisiebner.at/messinstrumente/Messinstrumente_2019-06-14.zip
https://zadig.akeo.ie/downloads/

I wanted to make a quick recap as this thread has gotten pretty long and it actually took me awhile to sort out some of the details and find the original posts that had the relevant information.
I also had trouble with Rigol's Ultra Sigma when trying to issue the SCPI commands, and ted572 (Thank you!) had made a suggestion to use Messinstrumente, and that worked immediately with no issue after installing the Zadig USB driver for the device.

I'm including the rigol-key.zip with this post for ease of download, but credit must go to tossu

A huge thank you to volkimel, tv84, tossu for making this hack happen.

Followed Vaiti's quick guide, after connecting my DP832 with the PC via USB cable I installed the zadic driver on my PC, started Messinstrumente and shot the command over - BAM - it worked like a charm for me  :clap: :clap: :clap:

 :-+ :-+ :-+ Biggest thanks to volkimel, tv84, tossu and Vaiti for the hack and posting a quick guide that not everybody has to dig through the whole thread  :-+ :-+ :-+

0806 denotes 0.8x0.6 millimeters correct? If so, are you sure they aren't 0805's? Those are more readily available on eBay and Aliexpress, the 0806's seem to be non-existent.

I'd guess from below it's a typo of an imperial size:

Here is a Digikey search of 0806 LED's:
https://www.digikey.com/products/en/optoelectronics/led-lighting-white/124?k=led+0806&k=&pkeyword=led+0806&sv=0&pv16=3364&pv16=3790&sf=1&FV=ffe0007c&quantity=&ColumnSort=0&page=1&pageSize=25

They are 0806 imperial sized SMD packages -- 0.080" L x 0.065" W (2.04mm x 1.64mm)
