Compliance and Warranty

This TAA-compliant device is manufactured in the United States and meets RoHS environmental standards. Backed by a comprehensive 1-year limited warranty, ensuring reliable performance for your industrial communication needs.

BLACK BOX® Universal RS-232 til RS-422/485 Converter med opto-isolering isolerer og konverterer RS-232-signaler til RS-422/RS-485-signaler og omvendt. I motsetning til andre konvertere kreves ingen ekstern programvare for å kontrollere datagjennomstrømning. RS-232-inngangen er koblet for DCE gjennom en DB9 hunnkontakt, og RS-422/RS-485-signaler er koblet til gjennom en avtakbar terminalblokk. For å levere ekstern strøm til terminalblokken trenger du vår 120-VAC/12-VDC veggmontert strømforsyning (PS1003).

For RS-232 krever tilkoblingen RD, TD og Signaljord.

I RS-422-modus er driveren alltid aktivert for full-dupleks kommunikasjon. Et tvunnet par er nødvendig for sending, og et tvunnet par er også nødvendig for mottak. En jordreferanseledning er også nødvendig. Bryterinnstillinger er Bryter 1: RS-422; Bryter 2: Echo På; Brytere 3 og 4: 4 Wire.

I begge RS-485-modusene aktiveres RS-485-driveren automatisk under hver romtilstand ved tilstedeværelsen av et RS-232-signal. Når RS-232-data er i en markert eller inaktiv tilstand, er RS-485-driveren deaktivert, og RS-485-datalinjene holdes i en markert tilstand av biasen som tilbys av en 4,7-ohm resistor; verdien av denne resistoren kan måtte endres avhengig av termineringen du bruker.

For å koble til flere RS-485-enheter med minimal ledning, velg enhetens 2-tråds, halvdupleks RS-485-modus. Når data er forespurt, sender den adresserte enheten og går deretter tilbake til mottaksstatus. Bryterinnstillinger for denne modusen er Bryter 1: RS-485; Bryter 2: Echo Av; Brytere 3 og 4: 2 Wire.

For 4-tråds master/slave-kretser, velg enhetens 4-tråds, full-dupleks RS-485-modus. I denne modusen kan adresserte enheter motta data mens de sender data fra en tidligere forespørsel. Når den brukes som en master i et enkelt-master-system, kan Bryter 1 velges fordi enheten er den eneste senderen i systemet. Når den brukes som en RS-485-slave, må RS-232-enheten tilby adresserbarhet. Biasing i et master/slave-system tilbys av enden av linjen som er slave. Bryterinnstillinger for denne modusen er Bryter 1: RS-485; Bryter 2: Echo På; Brytere 3 og 4: 4 Wire.

FAQ

The Black Box Universal RS-232 to RS-422/485 Converter features 2000-VAC isolation, selectable RS-422 operation, RS-485 support for both 2-wire half-duplex and 4-wire full-duplex modes, and automatic RS-485 driver control. It doesn't require external software for data flow control and comes with a DB9 female connector for RS-232 input and a removable terminal block for RS-422/RS-485 signals.

The converter has compact dimensions measuring 1.7 inches in height, 0.9 inches in width, and 3.9 inches in depth. It features an external form factor design that makes it easily accessible and installable.

In RS-485 mode, the driver is automatically enabled during each space state by RS-232 signal presence. When RS-232 data is in mark or idle state, the RS-485 driver disables and data lines are held in mark state by a 4.7-ohm resistor. It supports both 2-wire half-duplex and 4-wire full-duplex operations, with specific switch settings for each mode.

The converter requires external power supplied through a terminal block connection. It specifically needs a 120-VAC/12-VDC Wallmount Power Supply (PS1003, sold separately) to function properly.

The converter is RoHS certified and TAA compliant. It's environmentally friendly and manufactured in the United States, meeting various regulatory standards for electronic equipment. The 2000-VAC isolation certification ensures robust protection between input and output circuits.

For RS-422 mode configuration, set Switch 1 to RS-422, Switch 2 to Echo On, and Switches 3 and 4 to 4 Wire. In this mode, the driver is always enabled for full-duplex communications, requiring a twisted pair for transmit, another for receive, and a ground reference wire.

The Black Box Universal RS-232 to RS-422/485 Converter comes with a 1 Year Limited Warranty, providing coverage against manufacturing defects and ensuring customer support during this period.

In 2-wire half-duplex RS-485 mode, the device allows connection to multiple RS-485 devices with minimal wiring. The configuration requires Switch 1 set to RS-485, Switch 2 to Echo Off, and Switches 3 and 4 to 2 Wire. In this mode, devices transmit data when requested and then return to receive status.
