using a standard USB cable, only. Of course, for any motor movement main supply via supply input
connector is required.
NOTICE
Due to hardware ressource sharing USB and CAN communication interfaces are
not available at the same time. As soon as USB is physically attached to a host or
hub the CAN interface will be switched off.

4.5 I/O Connector
The PD42-x-1241 offers several inputs (two of them optically isolated) and one digital (open-drain) output.
The inputs include support for stop switches (left and right), home switch, step/direction, incremental A/B
channel encoder and analog (0. . . +10V) input. All this functionality is available via one 8pin JST PH series
I/O connector.
