The LDM35 signal powered RS-232 line driver is designed to allow video display terminals (VDTs) and other RS-232 devices to be connected over distances sufficient to cover any industrial or institutional complex of buildings. These limited distance modems feature a rugged enclosure small enough to mount on the back panel of VDT units, saving valuable desk and floor space. The LDM35 RS-232 line driver does not require a power supply for operation. The use of low power circuits and a sensitive optical receiver allows the devices to derive all necessary power from the RS-232 data and control signal. They are designed for full-duplex, asynchronous operation over two, DC-continuity, non-loaded, twisted-wire pairs. Two-wire simplex operation may be accomplished over two wires. The modem circuits and, consequently, the host device are protected from electrical transients due to lightning strikes or operation of heavy industrial equipment.

Our customer was looking for ways to improve efficiency and reliability, and reduce operation costs and overheads for their manufacturing facility. The initial step in this transformation was to add additional monitoring and measurements to several areas of their facility to allow the collection of usage data from older machinery for analysis. The machinery to be analysed would be located in many areas of the complex, with some sitting in concrete outbuildings far from the source of the main network.
