apcupsd doesn't show voltage with "SmartUPS 1000 LCD"

I’m trying to config apcupsd on my Ubuntu 10.04 Server, I’ve got an "APC Smart UPS 1000 LCD" connected via USB ( Bus 003 Device 003: ID 051d:0003 American Power Conversion UPS ).

My apcupsd.conf file highlights:

UPSCABLE usb
UPSTYPE usb
DEVICE

And the apcaccess outputs is:

How can I read others data that I can see on my UPS display?
Such as voltage in / out, load capacity and other stuff.

Thanks!
