[dsg-hallb_rich] [EXTERNAL] USB extender for raspberries - installation position in RICH sector I

[Marco Contalbrigo]

Hi Tyler,
to check the Raspberry funcionality is a good suggestion.

They are powered via the CAEN LV and activate the internal
camera. The same CAEN LV activate LED lights internal to
the RICH. Due to this, I would say the test should be
done carefully (PMT must be off) and by experts. The
proper LV channels are not mapped in the slow control panel
for safety (avoid accidental power by users).

Ciao, Marco.
