What is the typical specification of RS485 port in MiCOM P127 relay ?

Connections to RS485 are made using ring terminals. It is recommended that a two core screened cable, is used with a maximum total length of 1000 m or a 200nF total cable
capacitance.
Typical specification:
-> Each core: 16/0.2 mm copper conductor, PVC insulated
-> Nominal conductor area: 0.5 mm² per core
-> Screen: Overall braid, PVC sheathed
-> Linear capacitance between conductor and earth: 100pF/m.
