I suppose that is good news in that it looks like a software thing then.

I have been pondering changing it for a.n.other 2 or 3 channel PSU to get 0-60v and a high current, might have a look around and see what will fit the bill.  Defeats the point of scripting tests if you have to keep stopping to reset the PSU to get the comms back.

I have never seen any issue with my DP832 resetting or getting on/off the network.

Several of us have scripted this PSU, e.g. to analyze the acuracy of the DAC and ADC and have had no issue. In one of my tests, I did a full 1mV sweep of the whole 30V range, which is almost 24hrs of runtime, with no issue.

Obviously, some people have issues with their DP832, but I wouldn't panic and automatically assume this is wide spread and broken on all units. I am not sure what alternative PSU there is that will give you more perceived stability and specs in this price range.

I haven't always had issues, but it may well be a symptom of something else going on internally, some days are better than others.  There is no panic, but a wider voltage range and higher current would also be handy for the things I get up to these days.  I've had it 2.5 years now and works perfectly with the exception of the ethernet issue, which is just getting really annoying.

Have you excluded all other possibilities? ie: swapped computers / routers etc to make sure it's not some other part of the setup that's causing the issue?

Yes, swapped leads and even switches around, the issue always remains with the DP832A.  It will drop out using DHCP or with a static IP assigned too.

Macbeth:
Have you tried it with USB instead of Ethernet? I'm ashamed to say I haven't even tried the Ethernet option myself, but haven't had issues with USB.
