Is it possible to just reinstall v1.14 after upgrading to this semi-official v1.16 beta firmware?

We're using the PSUs in a production environment, therefore I can't install a not really officially released firmware on all units. If downgrades back to v1.14 are possible, I might give it a try on the unit I'm using on a daily basis, though. As I'm unable to reproduce the reboots in any known way and they seem to occur pretty randomly and sometimes not at all for weeks, it might take quite some time to get some results.

I'm not sure about downgrade from 1.16 to 1.14.  As you have some concerns for your production environment, perhaps you can ask Rigol about downgrade option and also to confirm with them that v1.16 is designed to address the reboot issue.  Other people here already confirmed that but you can always check.  Maybe Rigol will eventually release v1.16 if they realize the reboot issue is more widespread.  So, doesn't hurt to check things with them before giving it a shot.

Unfortunately I don't have any contacts at Rigol. Just regular bug-reports via their website and it seems several guys here on the forum tried this already without getting more information?!

I guess I just give the v1.16-beta a shot on my PSU. It is one of our oldest units (about 5 years, now) and if v1.16-beta has some really bad issues and can't be downgraded back to v1.14 I guess it just broke down... ;-)

Due to the random nature of the resets I guess I won't really be able to tell, whether v1.16 fixes the resets or not, unless I still get resets even with the newer firmware. If I don't see resets, it might also be just a lucky run, like I also seem to have with v1.14 some times (sometimes not a single reset in several weeks of daily use).

thn788:
Ok, some information on the v1.16-beta upgrade:

* Probably most important: my unit didn't catch fire (your mileage may vary, though)
* Upgrade to v1.16-beta is done exactly like previous releases; for the mainboard as well as for the two analog boards
* Downgrade back to v1.14 can be done without problems just the same way
* Quite a lot of the configuration seems to get reset to factory(?) defaults,

* e.g. "Display Mode" returns to the "normal" setting, OVP and OCP are disabled, Limits get reset to maximum, Language gets reset to Chinese
* yes, it feels a little disturbing when you install a mysterious beta-release and immediately after the upgrade you are greeted by a warning dialog, which you can't read because it is in Chinese... - guess it was just the "USB device detected" dialog.
* Files saved on the internal storage of the PSU didn't get erased during the update, though.
* Voltage output and current measurements don't seem to have changed after the update either, so I suppose the calibration data seems to have been retained, as well.
* For DP8xx (non-A) users: no, unfortunately I have no idea if your installed options will be reset or retained.Version information before update

If I still notice any more sudden resets with v1.16-beta, I'll let you know immediately.

TurboTom:
My DP811 still resets itself once in a while, even after I updated it to F/W 1.16 beta. AFAIK F/W 1.16 was meant to solve the problem of the frequent network dropoffs.

Since the analog hardware of the DP811 is considerable different from the DP832 (which I've also got but didn't notice a single reset event on that one...), I guess the problem is related only to the front panel board. It's quite interesting to see the problem really appears to be more wide-spread than anticipated. And apparently Rigol hasn't got a solution for it yet.
