Hello,
I don't know if anyone has already referred this, but I was getting some trouble communicating with my DP832A with RS-232.
If I send *IDN? several times, some did not get the replay, others got an error bip on the PSU, and next I would receive the answer twice, or not the complete string.
My version was 00.01.06.00.00, analog 01.01.07.01.01.07, then I updated to 00.01.09.00.01 analog 01.02.00.01.02.00, and now it seams a lot better on answer.
I used the update in the forum.
Looks stable so far, and I think the new classic layout is way better than the pie one.
I hope this helps others.
Regards,
ZJS
