I just bought one of these 2nd hand from a CN member, and can't determine if the unit will function correctly if it is NOT connected to a PC via the USB cable. Is it capable of standalone operation with reduced functionality, like not being able to switch the power ports on or off? This does not seem to be covered in the manual.
I don't have a spare USB port at my OTA and currently only need it to be supplying power to my cameras and mount. Thanks for your feedback.
