LCM100 Power Line Carrier Modem Features
The LCM100 Line Carrier Modem sends and receives digital data over power lines in a facility. It permits full-duplex asynchronous data transmission over 120V or 240V power lines at data rates from 0 to 9600 baud. The LCM eliminates costly cable installations and, without the need for other modems or special equipment, achieves efficient data rates with significant savings. Versatile. The LCM is portable and easy to install. The LCM lets you take a PC, PLC or terminal throughout the office or plant and provides instant access to other equipment by simply plugging it into any wall outlet or line connection. For example: Terminal to computer, Computer to plotter, Phone modem to computer Configuration. The LCM100 supports three-wire RS232C (other RS232 control signals are simulated under jumper control) communications. Two distinct units make up a pair for a complete communications link— one is attached to the Data Communication Equipment (computer and the other to the Data Terminal Equipment (CRT, printer or other peripheral). Each unit is plugged into an AC receptacle near the communications equipment and the associated digital data cable plugged into the LCM100 unit. Range. The LCM100 provides a communication range of up to 5,000 feet (1.52 km). This range is measured through the building’s electrical wiring. Applications. Applications include automated materials handling equipment, stacker cranes, rotating casting tables, electronic sign control, conveyor belt monitoring and general industrial data communications.
