Power, Com and I/O Connector
Product Reference Guide 159
* 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 "RS422 Full Duplex Interface" on page 57 for connection
details.
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.
