Need help hacking DP832 for multicolour option.

<< < (50/91) > >>

1anX:
Can you please detail how to use the C program to hack the DG1022Z.
I have a DG1022Z unit that I would love to run at 60MHz.
Just need a sequence of (simple) steps I can follow to get there. Any help much appreciated!

Long time listener, first time caller. Massive thanks to tossu for sharing his efforts here and helping the rest of us. I bought myself a DP832 some time ago and while it's been a fantastic bench supply, I was annoyed that it lacked the multi-colour display abilities of it's big brother. Your discovery is exactly what I was hoping for! I was able to apply the change quickly and easily. It's a relatively minor quality of life improvement, but it has made the power supply feel complete!

I wanted to share a few notes for others just in case anyone gets snagged up:


* The USB drive must be formatted as FAT, not FAT32 or exFAT. On Windows, USB sticks with a partition size over 4GB in size will not show "FAT" in the possible format options. To get around this, you can use Window's Disk Management utility (Run "diskmgmt.msc" from a Run dialog or type it in the Start menu) to delete the single large partition, and then create a new one 3.5GB or smaller. This will let you format it as FAT. I have no small USB sticks kicking around and was forced to do this, and I can confirm it works just fine.
* I could not get the Windows telnet client to work... it would sit on the "Connecting to..." stage forever. The DP832 was pingable on the network, and the IP address + port was correct, so I am not sure what the issue was. I ended up using PuTTy to connect via telnet and issue the SCPI command, which worked perfectly.
* All of the licenses that I applied before this modification were still there afterwards.
Thank you again!

What forms of computer do you own?  There are only 2 'challenges':

1. Get an (old) USB stick formatted correctly
2. Get some form of telnet communicating with your DG1022Z via LAN (or maybe USB).

You can Google telnet and find all sorts of options - windows 10 command prompt worked for me after adding telnet to windows but it's sort of clunky as there are no success messages after typing telnet <IP_address> 5555 (e.g. 10.0.0.123 5555) you just see a blank screen but, once you have telneted to your DG1022Z, try the *IDN? command and you should see a line of information returned like...

Rigol Technologies,DG1022Z,DG1ZAxxxxxxxxx,03.01.12

If you get this far, all you have to do is create and plug in the correctly formatted USB stick to the front of your DG1022Z and issue the command...

:PROJ:STAT MODEL,DG1062Z

If you're successful, you will get no response over telnet and there will be no messages on the screen of the DG1022Z.
If you see an "error generated by remote interface command" briefly popping up on the DG1022Z screen, then you probably have an issue with your USB drive.

How to create the USB stick and how to telnet are covered in multiple places in this thread.

One thing I've noticed is that saved configurations through the store>browser menu won't load after upgrade with an 'incorrect format' message.  You have to recreate and resave over the old stored info and then it works so some may want to take pictures of your saved configs.

I have win 10 PCs but could run Linux of a USB mem stick if needed.
Thanks for the info, I will give it a try!

I tried Windows and Ubuntu but, in the end, the issue was the thumb drive and I eventually made it all work using telnet from a command prompt in Win 10 with telnet service added.  As I already said; if you can telnet and get a response to *IDN? but then see "error generated by remote interface command" popping up briefly when you try to send the :PROJ:STAT MODEL,DG1062Z command, then the issue is with the USB drive - a recent comment says the drive has to be formatted in FAT but mine was FAT32.

Good luck
