IC821A

BLACK BOX® Universal RS-232 til RS-422/485 Konverter med Opto-Isolering isolerer og konverterer RS-232 signaler til RS-422/RS-485 signaler og vice versa. I modsætning til andre konvertere kræves der ikke ekstern software for at kontrollere databehandling. RS-232 indgangen er ledet til DCE gennem en DB9 hunstik, og RS-422/RS-485 signaler er forbundet gennem en aftagelig terminalblok. For at levere ekstern strøm til terminalblokken skal du bruge vores 120-VAC/12-VDC Vægmonterede Strømadapter (PS1003).

For RS-232 kræver forbindelsen RD, TD og Signaljord.

I RS-422 tilstand er driveren altid aktiveret for fuld duplex kommunikation. Et snoet par er påkrævet til transmission, og et snoet par er også påkrævet til modtagelse. En jordreferenceledning er også nødvendig. Switch indstillinger er Switch 1: RS-422; Switch 2: Echo On; Switches 3 og 4: 4 Wire.

I begge RS-485 tilstande aktiveres RS-485 driveren automatisk under hver space state ved tilstedeværelsen af et RS-232 signal. Når RS-232 data er i en mark eller idle tilstand, deaktiveres RS-485 driveren, og RS-485 datalinjer holdes i en mark tilstand af biasen leveret af en 4,7-ohm modstand; værdien af denne modstand kan have brug for at blive ændret, afhængigt af den termination du bruger.

For at forbinde til flere RS-485 enheder med minimal ledning, vælg enhedens 2-wire, halv duplex RS-485 tilstand. Når data efterspørges, transmitterer den adresserede enhed og går derefter tilbage til modtagestatus. Switch indstillinger for denne tilstand er Switch 1: RS-485; Switch 2: Echo Off; Switches 3 og 4: 2 Wire.

For 4-wire master/slave kredsløb, vælg enhedens 4-wire, fuld duplex RS-485 tilstand. I denne tilstand kan adresserede enheder modtage data, mens de transmitterer data fra en tidligere anmodning. Når den bruges som master i et enkelt-master system, kan Switch 1 vælges, fordi enheden er den eneste transmitter i systemet. Når den bruges som RS-485 slave, skal RS-232 enheden levere adresserbarhed. Biasing i et master/slave system leveres af end-of-line slaven. Switch indstillinger for denne tilstand er Switch 1: RS-485; Switch 2: Echo On; Switches 3 og 4: 4 Wire.
