I've acquired and installed NUT 2.4.1 on a D-Link DNS323 NAS. With 
exception of Load and Battery Temp readings all works well. A upsc 
ups at localhost command returns;

My ups.conf is;
[APC_UPS]
    driver = usbhid-ups
    port = USB
    desc = "Back-UPS RS 900"

The DNS323 has the following attributes;
- 500 Mhz Marvell 88F5181 proprietary Feroceon ARM CPU architecture

- U-Boot 1.7.3-5182 Bootloader 
<ftp://ftp.dlink.com/GPL/DNS-323/u-boot_1_7_3_5182.tgz>




The systems message.log contains several lines with;

Can anyone offer any suggestions as to why the readings are weird and 
how to fix this issue?
