Na mgbakwunye na wiwi ziri ezi nke ahịrị RS485, achọrọ modul interface akọwapụtara nke onye nrụpụta maka ntinye n'ime sistemụ akpaaka dị iche iche: maka sistemụ dabere na KNX, ndọtị RS485 (dịka ọnụ ụzọ KNX-TP/RS485) dị, nke na-agbanwe ọkwa na usoro n'etiti bọs KNX na ngwaọrụ RS485. Na sistemụ Loxone, a na-eji ndọtị Loxone RS485 gọọmentị kama, nke etinyere ozugbo na gburugburu Loxone Miniserver.
Mgbe ị na-ahọrọ interface kwesịrị ekwesị, ọ dị mkpa karịsịa ijide n'aka na ọ bụghị ọnụ ụzọ ámá Modbus RS485, kama ọ bụ ọnụ ụzọ ámá RS485 doro anya. Südwind na-eji protocol nwe nke na-adakọghị na ọkọlọtọ Modbus.
Ntọala mgbanwe DIP

Parametrization
A ga-ahazi usoro nzikọrịta ozi serial na ndọtị RS485:
