Please stop detecting UPS serial number
I have a Tripp Lite SMART1500LCD UPS attached to my RN2120 via USB. Since day 1, the 2120 has given me hourly warnings that it cannot communicate with the UPS. This happens with OS 6.5, 6.6 and 6.7.5.
With extensive online research, I found another user who temporarily fixed the same problem by editing /etc/nut/ups.conf and commenting out the line:
serial = xxxxxx
then restarting nut.
I used SSH to examine my own ups.conf and tried the same. I shut down nut and restarted it - it recognzed my UPS perfectly. I noticed that nut started on its own saw the Tripp Lite serial number as "FW-2473 A" with a space. Front View always saw it as "FW-2473_A".
Of course my edit was wiped out on every reboot. I tried making /etc/nut/ups.conf read only and even immutable, but Front View found somewhere else to put the configuration and still shows an "unknown" UPS with the serial number "FW-2473_A".
If ReadyNAS would just stop detecting the Tripp Lite serial number, I would be fine. If ReadyNAS detected it properly with the space and escaped it correctly in ups.conf, I would be fine.

Just curious, did you try putting " " around your serial number with the space rather than putting the _ in leiu of the space? You could then try to restart NUT instead of restarting the whole NAS and see if ReadyNAS handles it better.
