All models of APC from the Back-UPS Pro to the Matrix-UPS have the same
interface and will work with the custom "apc-advanced" (which I designed)
or the "apc-pnp" (standard cable from APC) cables. Both cables have the
same dumb-signalling abilities but obviously the "apc-pnp" cable also
supports the smart-signalling modes.
One further note: The APC UPSs default to dumb-signalling on power-up
but retain whatever state they were last put in until they are next
power cycled. Thus, if you have a dual-boot system with windows and
use the standard APC software, when you boot back to linux, genpower
won't be able to talk dumb-signal to the UPS. If you write an "R"
to the serial port it will go back to dumb-signalling, but my quick
attempts to write a program to do such failed.
I believe "apcd" require the older black smart-signalling cable to work,
but could be wrong. APC units used to come with both cables, but newer
ones may only come with the Plug'n'Play cable.
