[Nut-upsuser] beginner questions about AEC Star T4110

[Gémes Géza]

Hi,

I've got an AEC Star T4110 connected with an RS232 port by a megatec cable.
On the list of supported devices
(http://www.networkupstools.org/stable-hcl.html) there is only one AEC
device, so I tried genericups with upstype=21. The problem is, that the
UPS (while being on-line) reports constantly being on battery.
# upsc aec ups.status
OB
My question is:
What is the recommended procedure to debug this (what parameters try to
change in what order)?
About the system:
Ubuntu 10.04 (kernel 2.6.32-33-generic)
NUT: 2.4.3-1ubuntu3.1

Thank you for any idea!

Cheers

Geza
