External dimension


• Cable URG-C001(Option)


*During booting, 500mA current is required. If the sensor can not be started with a single USB port, please use 2 USB cables(not included) for power supply from 2 USB ports.
Please connect to 2 independent USB ports which can supply 500mA.

PC's motherboard could be broken if the sensor is connected to the USB ports which are not able to supply 500mA×2.

The GND lines connected to the USB are all shorted.
