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.
