* Do not leave floating, see par. 5.3.2 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;

 for direct connections, connect the main interface cable shield to pin 1 of the 25-pin

connector.
