Note the computer recognizes the camera only if it is also powered. Camera

point of view.

When the camera is powered and connected to the computer (with

appropriate drivers installed), it starts to initialize filter wheel. The internal

filter wheel starts to rotate and the camera control unit searches for the filter

wheel home position. This operation takes a few seconds, during which the

camera does not respond to computer commands. Camera indicates this

state by flashing the orange LED. See the “Camera LED state indicator”

chapter for details.

The camera is fully powered by the external power supply, it does not use

USB cable power lines. This means it does not draw laptop batteries and

long USB cables with thin power lines (which can cause voltage drops and

power-related problems for USB-powered devices) does not affect the G3

camera operation.
