Passiver bidirektionaler RS232-zu-RS485-Konverter in Industriequalität für die Kommunikation über große Entfernungen zwischen industriellen (kommerziellen) Geräten.
Die E/A-Schaltung steuert automatisch den Datenfluss, sodass kein Handshake-Signal erforderlich ist, wodurch sichergestellt wird, dass das im RS232-Halbduplexmodus geschriebene Programm ohne Änderung im RS485-Modus ausgeführt werden kann.
Der eingebaute Transient Voltage Suppressor (TVS) unterstützt einen 600-W-Überspannungsschutz und einen 15-kV-Statikschutz, der Geräte effektiv vor Beschädigungen schützt.
Es ist keine externe Stromversorgung erforderlich, es verwendet eine "RS232-Ladepumpe", um den Konverter zum Laufen zu bringen, und es kann Strom erhalten, ohne den seriellen 232-Port zu initialisieren.
Geeignet für Zugangskontrollsysteme, Überwachungsgeräte, Endgeräte, Industriesteuerungen, Erfassung digitaler Instrumente, Mikrocontroller usw.

Der Seriell-Konverter ermöglicht die Kommunikation zwischen Computern mit serieller RS-232 Schnittstelle und Geräten, die den seriellen Schnittstellen-Standard RS-485 unterstützen.
Aufgrung der Signal-Umwandlung von RS-232- zu RS-485 ergibt sich eine höhere Übertragungs-Reichweite von 5 m (RS-232 Seite) auf 1200 m (RS-485 Seite).
Der integrierte Transceiver ermöglicht den verzögerungsfreien Einsatz und die automatische Erkennung der Daten-Transferrichtung der I/O-Ports - Die Erkennung benötigt keine RTS/DTR Handshake-Signale.
Der Adapter kann zwischen zwei Host-Computern (Punkt-zu-Punkt) oder einem Host-Computer und einem/mehreren Perepherie-Gerät(en) (Punkt-zu-Multi-Punkt) verwendet werden.
Einsatzgebiete erstrecken sich von industriellen Systemen über Kartenlesesysteme, Zugangs- & Bezahlsysteme (Maut, ÖPNV, Parkhäuser), vernetzte Elektro-Ladesäulen bis hin zu Maschinenbau-Anwendungen.
