For my home, I bought a Back-UPS Pro 1100 that was inexpensive. It came
with a 940-0020C serial cable. Unfortunately, this only supports simple
signalling, so you can't monitor the UPS for its vital statistics
regarding percentage battery life left, etc. I guess that's why it was
inexpensive. But, it does work with apcupsd, and you do get
notification of power loss and even a critical power low warning signal
you can use to trigger shutdown of your machines. It has worked well
I don't know if your statement about the "entire Back-UPS model line"
also encompassed the Back-UPS Pro models. I just wanted to say there
was at least one Back-UPS Pro UPS that did support monitoring/shutdown
capabilities, albeit the restricted simple signalling type.
I agree that if the OPs UPS doesn't have any type of data connection to
a host computer then it won't be possible to get it to interface with
apcupsd. However, I haven't heard of an APC UPS that didn't come with
some kind of data cable, so it would be useful if the OP posted the
precise model: there are several in the Back-UPS 500 line, such as the
Back-UPS 500; Back-UPS CS 500; Back-UPS ES 500; etc. All of them
support either a serial or USB cable. (The CS supports both.)
