Electromagnetic compatibility (EMC) is the ability of an electrical device to
function satisfactorily in its electromagnetic environment without affecting
this environment.
The bus connectors and the RS 485 repeaters described in this manual
comply with the statutory requirements for EMC.
The details of interference immunity and RFI suppression are listed below.
Table A-1 lists the details of electromagnetic compatibility with regard to
pulse interference.
