Full duplex communication runs transmit and receive on separate conductors, thus autosense is not
required. The AIB modules support full duplex transmission as either RS-422 or TTL data.
Connector pin designations for the front panel WAGO connectors are given in the table below with default
configuration shaded.

Switch settings for the various configurations are given in Table 5.6-4. When using the module in RS-422
or TTL input configuration, the autosense mode (SW3, SW4) should be set for full-duplex operation.
Autosense baud rate settings (SW5) are ignored when the module is in full-duplex or simplex modes.
