<div class="PlainText">Hi Tyler,<br>
to check the Raspberry funcionality is a good suggestion.<br>
<br>
They are powered via the CAEN LV and activate the internal<br>
camera. The same CAEN LV activate LED lights internal to<br>
the RICH. Due to this, I would say the test should be<br>
done carefully (PMT must be off) and by experts. The<br>
proper LV channels are not mapped in the slow control panel<br>
for safety (avoid accidental power by users).<br>
<br>
Ciao, Marco.<br>
