[Nut-upsuser] Differences between USB and serial on an MGE Pulsar Evolution 3000

[Neil A. Hillard]

Hi Arnaud,

Many thanks for your quick reply.

Many thanks for the pointer.  Don't know how I managed to miss that 
during my searching but that details my experiences, too.

I actually noticed newmge-shut just after I sent my original message so 
I've got the upsc output handy (listed below).  I've highlighted the 
values that differ from the USB output (with an asterisk) and I've 
spotted that there are a few parameters missing:

input.frequency.extended
input.frequency.nominal
input.voltage.extended
ups.beeper.status
ups.test.result

If there's anything I can do to help get these added or perform some 
more testing then please let me know.

Many thanks once again,


Neil.
