Need help hacking DP832 for multicolour option.

I partitioned a 16GB drive to 4096MB, full formatted it with FAT32 and then copied the keyfile.bin

Most probably, your USB drive is not set up properly. Make sure you insert the drive after the PSU has booted. If you prepared the drive using the old method Vaiti described, try using the disk image I made later: https://www.eevblog.com/forum/testgear/need-help-hacking-dp832-for-multicolour-option/msg2475702/#msg2475702

Thanks Tossu. the disk image method worked and I am greeted with a color display !!

FAT32 worked as well in my case :)

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 ?

Read again tossu's message, "You can format a drive as FAT "..

Anyway, the trick is to have the 'magic' sector written with the proper value, give it a try with some other usb sticks.

/PS
LoL for the time it took me to write this, it was already answered and done.. :-))

TurboTom:
Yes, and for the DG800 / DG900 with a slightly different "Magic Stick"  ;)

Cheers,
Thomas
