<p>I can confirm there was a protocol change somewhat recently for this model.</p>
<p>It should still be HID-PDC compliant, so I believe it is possible to get it working. Others on the mailing list probably have some useful ideas.</p>

</p>
<p>I'm still remote so my ability to run tests for non-networked devices is somewhat limited.
<br>

<p>If there's any info I can provide from the Tripp Lite side that we don't already have, feel free to ping me.
