Pos. 2 = ON: RS422 mode
Pos. 3 = ON/OFF: four−wire conductor/two−wire conductor (only relevant for RS485 mode)
Pos. 4 = ON/OFF: echo function activated/deactivated (only relevant for RS485 mode +
two−wire conductor)
MC−ISI_004
Set the mode:
Mode DIP switch setting
RS485 mode, two−wire conductor, deactivated echo function (default)
RS485 mode, two−wire conductor, activated echo function
RS485 mode, four−wire conductor

Pos. 1 = ON
Pos. 1+4 = ON
Pos. 1+3 = ON
Pos. 2 = ON
