Unable to operate Orbbec

Just rec’d my orbbec and does not seem to register being powered when plugged in. Remote doesn’t seem to work. Not sure if I’m missing a basic thing or if I have a broken machine.

Is there a newbie walk thru on setting up on a mac? Tried the OpenNI and not able to get it to work.

Just comes w/ hdmi & power. Do I need to additionally connect via usb or LAN or no?

Beginner here-- any step by steps for beginners out there? Thank you-k
