[Nut-upsuser] PowerWare 9120 via USB?

[Tobias Balle-Petersen]

Hello all.

I have now connected the UPS via a serial-cable to a PC running Debian Etch and Nut 2.0.4.

When running "upsdrvctl -u root start" I get:
Communications with UPS lost: Error executing command
Communications with UPS lost: Error executing command
Communications with UPS lost: Error executing command
Communications with UPS re-established
Connect to UPS on /dev/ttyS0 baudrate 9600
Model = PW9120 3000VA
Firmware = 02.60
Shutdown delay = 120 seconds


Is this the OK? Can I ignore the first errors?

"The thing is that if you have run it on the serial before you go to use the bcmxcp_usb driver it
should be set to 'request_only_mode'."


How do I set my UPS to "request_only_mode"?


Thanks,
Tobias
