As I mentioned in my April 1 post, CyberPower indicated to me in an
email when I contacted them that battery voltage is not supported.in
this model of UPS. I am rather disappointed in that but there is not
much we can do about it.

I looked around the site for firmware upgrades and found none.  There
are also no instructions in the manual on accomplishing a firmware

Just for grins I looked for firmware upgrades for a couple of other
models in a different series of UPS units and found no firmware
upgrades for any of those as well.  It would appear that they either
do not believe in firmware upgrades or I am looking in the wrong spot.
  I suspect the former as there is nothing in the sales literature as
well and normally when it is possible for a piece of equipment to
accept firmware upgrades, the manufacturer lists it as a feature.

 As an aside, is it possible that using the RS-232  port would produce
different results?  I would think both drivers would expect the data
to be in the same format so the results would be the same as well but
thought I would ask to be sure.
