No remote sense? :-//
No remote sense? :-//
Hello it seems Rigol hasn't added the remote sense since this power supply is intended to be used on a lab or desk, where the distance to the DUT is not far away.
Any question, please ask. We have some DP711 to test in case of special request.
I'm in doubt between DP832 and DP711, mostly because i prefer 30V/5A more then 30V/3A.
Hello! We are working on that video.
We will publish it soon. I will post here the link.
Thanks

If you parallel channels 1 and 2 on the DP832 you can do 30V/6A or in series 60V/3A.
Don't seem to find an international dealer for it though...

Hey Beard, thanks. I guess if I understand well, you could simply connect both output 1 & 2 on the same circuit, and manually calculate value, or Rigol do that for you?
Yes, thanks, http://www.batronix.com/pdf/Rigol/UserGuide/DP800_UserGuide_EN.pdf (http://www.batronix.com/pdf/Rigol/UserGuide/DP800_UserGuide_EN.pdf) on 58 Adobe PDF page, or 2-8, as in manual.
There is explanation, but as i'm not had oportunity to work with Bench PS, i'm not sure in reality, how all that looks like...
I really don't know why Stupid Beard, even as a joke... :)
You save me of buying DP711... at least for now... Photos are really great. If i see well, that small link, like infinity sign, actually represent connection between two adjacent channels?
Actually, procedure you are talking about is this one:

Thanks again for your effort! Really appreciated a ton!

Looks nice ... but ...
RS232 ? without USB at 2016 ?

Looks like quite a nice device. I do like the classic RS232 interface - I've done several test beds that use the RS232 interface from a simple microcontroller or a bit of VBA in Excel.

Hi Steve. I rarely hear about folks using the RS232 in instruments. Your setup might make for a nice vid.

Has anybody tested this device yet?

046fI opened my DP711 but could not find the FRAM chip. Is it located at the bottom side of the board?
I did see that a smal cap (47 uF / 50V) had vented its electrolite :(, so I will have to replace it.

i2cdump -y 1 83 cAlso replaced the bad cap. It was mounted in the wrong polarity!
Not confidence inspiring that a backwards cap made it through QA though...

So looking at photos, I noticed the safety info beside the plug on the DP711 states a max of 300W/400VA. Does that mean its actually capable of 60V 5A?
I did have to break the "Warranty void if removed"-sticker to find the bad cap. :PAmericans can just remove them since they violate federal law.
I've done some playing around with my DP712. Slurped the main firmware image off the SPI flash chip inside before and after the trial ran out. Unfortunately the license data is actually stored on an FRAM chip that I missed the first time I took it apart.
You should read back through this thread. I figured it out and the details are there.
This is not an ideal solution as it requires opening it up and leeching onto the FRAM chip with a device that talks i2c, but it works :)
They don't use ECC as riglol/rigup. It's a cascade of CRC16 calculations giving a 28-char license.
The only parameter that is needed for the calculations is the S/N.
The DP700 keygen is identical to the DL3000 keygen (with a different char_map). See here (https://www.eevblog.com/forum/testgear/new-rigol-dc-load-d3000-series/msg2710330/#msg2710330).

I've successfully licensed a DP711 (attached).
Example of licenses for someone curious:
Rigol DP700 S/N: DP7A123456789
Official License
DP7-TRIGER 22W5NBYPM6GUP27A68RY4VWQWH5L
DP7-TIMER T9ZKK8GPH7GUTA2BUDDYWJX8PKJ5
DP7-HIRES AES6FY3KV6GUV4ENR6QCBK8HH2CK
Need help to complete the entire procedure for generating serial numbers for HI-RES unlocking on DP711/712?
The question is to generate withount the hardware dissasembling and FRAM modification.
