Isolated Limited Distance Modem
and Modem Systems
Data communications in industrial and institutional environments can present special problems. Lines must be run over long distances, often ranging from thousands of feet to several miles, indoors and outdoors, and between buildings. Such data communications systems must be able to function in the presence of electrical transients and noise, ground loops, and surges from nearby lightning strikes.

Dataforth Corporation's rugged modems, rack-mounted modem systems, and new DCP485 series of DIN-mount, fully isolated RS-232/RS-485 converters are designed to "harden", protect, and extend the operating ranges of these data communications networks while providing additional benefits in reduced installation and maintenance costs.
RS232 / RS485 / Fiber Converters
RS232 / RS485 converters are designed to "harden", protect and extend operating ranges using standard RS232 / RS485 protocol and specifications. Dataforth's rugged modems, rack mounted systems and new DCP485 series of DIN mounted, fully isolated RS232 / RS485 converters extend the operating ranges of data communications networks while providing additional benefits in reduced installation and maintenance costs.
Limited Distance Modems
The LDM series of heavy duty communications modems greatly extends the distances over which computers, terminals, and other devices can communicate within hazardous industrial and institutional environments. Six models communicate over continuous dedicated wire pairs and distances up to 12 miles using standard RS-232 or -485 protocols. Two additional models feature fiber optic data links for total electrical isolation and operation up to two miles. Dataforth delivers the complete limited distance modem solutions.
