Re: [Apcupsd-users] apcaccess does not provide correct data

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

If this model does modbus over serial, that is your best bet, it's 
probably not reporting anything useful over the standard USB link (and 
modbus over USB is broken in apcupsd - don't use that).
