Impostazioni di terminazione RS-422A/RS-485

SW 501

Come illustrato nella mappa della struttura, quando il Controller e il modulo RS 422A/RS-485 sono connessi, le operazioni di terminazione debbono essere effettuate in base all’impedenza opposta dal cavo in ognuna delle uscite della linea di trasmissione, al fine di trasferire i segnali a lunga distanza controllando però la riflessione del segnale a bassa distanza.
