FEATURES

DESCRIPTION

IDM 50B is a frequency shift keyed (FSK) and quadrature amplitude modulation (QAM) modem for asynchronous and synchronous data transmission in 300-3400 Hz voice band. It is highly immune to interference and noise and permit extensive voice-band communication link utilization.
The modem supports several international standards ITU V.21, V.23, R.35, R.37, R.38A, R.38B, V.29, Bell 103, Bell 202 and proprietary Cegelec 1200/600Bd and Indactic 33 communication standards.
The modem can operate in half or full-duplex, point-to-point or point-to-multipoint mode. When using FSK modulation receive and transmit channels may be independently set.
The modem employs advanced DSP 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 ITU CCITT V.24 & V.28 (EIA RS-232C) communication interface. Additionally, for easy firmware upgrade a bootstrap loader is provided.

APPLICATION

IDM 50B is designed for use in SCADA systems mainly based upon power utility communication networks. Depending of modulation standard it can communicate through specialized, private or leased lines, radio links and power lines (PLC).

MOUNTING TYPES

IDM 50B is available as a desktop modem or in two different types of standard 19 inch rack:

  • 1U rack with 1, 2 or 3 modems per rack;
  • 3U rack with 10,12 or 14 modems per rack, and additional blank front plates covering unused slots.

All connectors at the rear side are accessible at the back openings.
