Need to change back UPS firmware version string (PROG)!

[Anonymous user]

I have an SUA750XLI (and an SUA1000I).
I discovered that the actual battery float voltage was higher than indicated by the UPS, and bit to high to be good for the batteries. After some Googling I found instructions on how to enter PROG-mode and recalibrate the battery voltage gain. It worked perfect.

BUT. At some point during PROG mode I accidently turned of caps lock and sent the command "b" for version string instead of "B" for battery. Before I realised caps lock was off I pressed at least + or -, r, R and B.

I know this for sure because my reported UPS firmware is now rRB.18.I instead of 680.18.I as it should be!
This means that my AP9617 NMC-card wont recognize the UPS anymore. Crap!

Can someone please help me to change it back?

(PS. Yes, I know all to well now why PROG mode is nothing for the end user because it can wreck the UPS).
I realize this information is sensitive, so a PM would also be really appreciated.

Problem was solved by entering PROG mode and inputting the correct data.

YES!
Solved it.
My UPS firmware revision is now reported as 680.18.I.

I'm happy. 🙂
