I am very happy with Stimtracker, and especially light sensor.
However I have a question.
my stimtracker is connected to responsebox (connected to Mac Pro via USB) via RJ45 TTL, and connected to same Mac Pro via USB.
when I turn on the Mac Pro, even without adaptor connected, the stimtracker’s light turns ON and it works.
maybe, the power from RJ45 make that phenomena.
Is it OK and natural?
I’m worry about connect adaptor and RJ45 power hurt the stimtracker.
