  • Convertitore da RS232 a RS485 passivo passivo di livello industriale per comunicazioni a lunga distanza tra dispositivi industriali (commerciali).
  • Il circuito I/O controlla automaticamente il flusso di dati, eliminando la necessità di un segnale di handshake, assicurando che il programma scritto in modalità half-duplex RS232 possa essere eseguito in modalità RS485 senza modifiche.
  • Il soppressore di tensione transitoria (TVS) integrato supporta una protezione da sovratensione da 600 W e una protezione statica da 15 KV, proteggendo efficacemente i dispositivi dai danni.
  • Non è richiesta alimentazione esterna, utilizza una "pompa di carica RS232" per far funzionare il convertitore e può ricevere alimentazione senza inizializzare la porta seriale 232.
  • Adatto per sistemi di controllo accessi, apparecchiature di sorveglianza, apparecchiature terminali, controllo industriale, acquisizione strumenti digitali, microcontrollori, ecc.

  • Il convertitore seriale consente la comunicazione tra computer con interfaccia seriale RS-232 e dispositivi che supportano lo standard di interfaccia seriale RS-485.
  • La conversione del segnale da RS-232 a RS-485 si traduce in un campo di trasmissione più elevato da 5 m (lato RS-232) a 1200 m (lato RS-485).
  • Il ricetrasmettitore integrato consente un funzionamento senza ritardi e il riconoscimento automatico della direzione di trasferimento dati delle porte I/O - il riconoscimento non richiede segnali di handshake RTS/DTR.
  • L'adattatore può essere utilizzato tra due computer host (punto-punto) o un computer host e uno o più dispositivi pereferici (punto-multipunto).
  • Le applicazioni spaziano dai sistemi industriali ai sistemi di lettura delle carte, sistemi di accesso e pagamento (pedaggio, trasporti pubblici, parcheggi multipiano), punti di ricarica elettrica in rete e applicazioni di ingegneria meccanica.
