Dataforth SCM9B-A2000 RS-232C/RS-485 Converter/Repeater Overview
Features:
- No External Flow Control Signals Required
- Optically-Isolated Bidirectional Data Flow
- Standard Data Rates: 300 to 115kbps
- Networking up to 4,000 Feet
The Dataforth SCM9B-A1000/A2000 Series RS-232C/RS-485 Converter/Repeater boxes convert RS-232
communication signal levels to the correct electrical signals required by
RS-485. The RS-485 communications standard is recommended when
many SCM9B modules, or other addressable devices, must be connected
to a host computer over long distances. The A1000 and A2000 converters
allow communications bus lengths up to 4,000 feet and data rates up to
115kbps using one twisted pair of wires.
The RS-485 standard allows for bidirectional data on the same pair of wires. Therefore, some means of arbitrating the data direction is required. The A1000 and A2000 automatically control the bus direction without external handshaking signals from the host. Host software written for half duplex RS-232 may be used without modification, RS-485 bus control is completely transparent to the user.
The A1000 and A2000 can also operate as repeaters for RS-485. Repeaters are required to extend communications bus lengths or to allow more than 32 RS-485 devices to be connected to a communications bus. A repeater simply reamplifies, or boosts, existing RS-485 signals transmitted over long distances.

What Customers Are Saying

Contacted Artisan for hard to find that has been out of circulation for nearly a decade. Their rapid response and availability exceeded all other suppliers. They supplied the part overnight to an out of state facility which allowed us to repair our equipment successfully. Well packed electronics. Well stated and professional documentation. I work with a hundred different suppliers any day of the week in my profession. Artisan remains at the very top of the bookmark tab. Thanks so much.
- Young L.
Artisan isn’t just a supplier with inventory. Their engineers helped diagnose a problem over the phone that would have taken us weeks to figure out!
- Brian S.
Artisan saved us headaches and money by helping us find a replacement Tektronix VXI module. Finding quality replacement parts is difficult and I'm glad they had what I needed.
- Tia W.
Quick process from getting a quote to getting the items we ordered.
