[Nut-upsuser] [Nut-upsdev] CyberPower 550SL reports LB and OB when on line power

[Chris Gatcombe]

Hi,

If it helps, I have a Cyberpower CP485SL/AE485, which may be 
similar enough to yours.

I'm using a straight-through serial cable (no twists or jumpers 
anywhere) and I'm using the genericups driver (type 7, though I 
think the type 22 works the same). I have not had to redfine any of 
the serial control signals in ups.conf.

Just running the driver (genericups -a MyUps -DDDDD) shows me 
sensible looking status values as the UPS goes first to battery, then 
to low battery, then shutting off.
