<br>
I have a Saclicru SPS One 900VA. This is a warranty replacement for an <br>
earlier SPS One 900, except the first was a model with UK plugs, and <br>
this one is with IEC.<br>
<br>
The first one used to work perfectly with the existing NUT <br>
configuration. With the new unit, although NUT starts and works for a <br>
while, eventually it stops working with a "stale data" message. I have <br>
checked the FAQ and I can't quite figure out if the section on stale <br>
data applies.<br>
<br>
I isolated the driver to get cleaner debug messages, and have provided <br>
them below. Once the stale message occurs, the only way to fix things is <br>
by rebooting the host running NUT (and connected to the UPS via USB).<br>
<br>
Unfortunately I haven't yet been able to see the output at the time the <br>
data becomes stale (terminal buffer not big enough). I can try piping it <br>
to a file.<br>
<br>
The output using -DD:<br>

<br>
I think this points to a change in the software in the UPS, but is there <br>
a way to work around this?<br>
<br>
Many thanks<br>
<br>
