IDM50 is a
frequency shift keyed modem for asynchronous data
transmission in 300-3400 Hz voice band. It uses binary
frequency modulation techniques which make it highly immune
to interference and noise and permit extensive voice-band
communication link utilization. The modem supports CCITT R.38A, R.38B and V.23 communication standards. Table of programmable channels depicts possible utilization of audio band. The modem can operate in half or full-duplex, point-to-point or point-to-multipoint mode, with receive and transmit channels independently set. The modem employs advanced microprocessor technology, thus offering high service flexibility through programmable features. Software configuration is performed via Hayes AT command set. AT commands can be initiated from any terminal application using RS-232 communication interface. Additionally, for easy firmware upgrade a bootstrap loader is provided. ApplicationIDM50 is designed for use in SCADA systems mainly based upon power utility communication networks. It can communicate through specialized, private or leased lines, radio links and power lines (PLC).Mounting TypesIDM50 is available as a desktop modem or in two different types of standard 19'' rack:*All connectors at the rear side are accessible at the back openings.
