Dataforth Corporation's high performance DCP485 fully isolated DIN rail RS-232/RS-485 converter/line driver provides a unique combination of protection, speed, and versatility for DIN rail mount industrial data communication applications.

The DCP485 converter allows computers, controllers, terminals, and other industrial I/O devices with RS-232 and/or RS-485 ports to communicate with each other over extended distances while protecting valuable equipment and signals from damage or degradation due to ground loops, power surges, lightning strikes, and other electrical hazards commonly found in industrial environments.

The DCP485 uses heavy-duty optical couplers and a transformer isolated DC-to-DC converter to provide very high electrical isolation of 6000VDC surge (1 minute) and 1500Vrms continuous. For added safety, ANSI/IEEE C37.90.1 surge protection is provided on all RS-232 and RS-485 inputs and outputs as well as on DC input.

The DCP485 is designed for full duplex operation over 2-wire pairs, and can also be operated in asynchronous 2-wire half-duplex or 2-wire simplex modes. Tri-state outputs permit multidropping of up to 32 data I/O devices. It is relatively fast for industrial applications, with a baud rate range of 0-115.2kbps over distances up to 7 miles.

For easy setup, markings on the exterior of the compact, DIN rail mount package (4.3" x 3.3" x 0.89", 109mm x 84mm x 22.5mm) provide all necessary information to quickly wire and set up the device. Four diagnostic LED indicators further simplify installation and troubleshooting.

The RS-232 interface includes Request To Send (RTS) and Data Terminal Ready (DTR) control lines, either of which can be used to enable the RS-485 transmitter. The DCP485 also offers automatic line switching in which the RS-485 transmitter is enabled automatically by each character sent on the RS-232 Transmit Data (TD) channel. In addition, the RS-485 transmitter and receiver can be enabled independently, either continuously or under RS-232 control. A useful null modem switch allows convenient DCE or DTE mode selection.

RS-232 connections can be made through male or female EIA 9-pin D-sub connectors, or a 3-wire RS-232 connection can be made using easily accessible, pluggable screw terminals. The device is powered from wide range voltages of +10V to +30VDC at 150mA max over an operating temperature range of -40°C to +60°C.

The DCP485 is part of Dataforth's extensive line of high performance industrial data communication products and systems, including stand-alone and rack-mounted limited distance modems and modem systems.
