The listed values are valid for shielded cables.
4.4.6
Communication without Insulation: RS-232
The communication via RS-232 is designed only for distances
≤
2.5 m. Therefore this inter-
face does not need to show an immunity. The immunity and the galvanic insulation is as-
sumed by the external data communications equipment.
You can find the electrical ambient conditions of data transmission equipment in the related
data sheets.
