In order to meet EMC requirements:
Connect the reader chassis to the plant earth ground by means of a flat copper braid shorter
than 100 mm; Connect your cable shield to the locking ring nut of the connector.
 When using the USB interface without Datalogic accessory cables, EMC compliance
requires the USB data and power signals originate from the same source (i.e. computer).
Max USB cable length from M12 17-pin connector is 2 meters. Incorrect disconnection
can result in damage to the USB hub.
 Do not leave floating, see par. 4.2.2 for connection details.
