Is it better to use USB A or USB B or RS232 to communicate over long distances?
The solutions is not that many. But first, is it a option to move the &quot;ALR-F800&quot; closer to the RF reader since it is a Ethernet and PoE device?
Otherwise is the solution only RS232 and at low bit rate. And what bitrate ? It depends mainly on two factors, distance and electrical interference (EMC) from electrical and electronic devices in the proximity to the cable, thus it could be reduced with a god shielded cable.
