The Data Connect IG202T-R38 is a Bell 202 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 permits 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 the 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 an RS-232 communication interface. Additionally, for easy firmware upgrade a bootstrap loader is provided.
The modem features programmable modem capability for SCADA or power utility communication networks. It can support a range of standards including ITUR.35, R.37, R.38A, R.38B, V.21, V.23, Bell 103, and Bell 202. It is Fully programmable via Hayes AT command set. The modem also features Specialized Line, Power Line Carrier, or radio communication, as well as half or full-duplex operating modes.

The IG202T-R38 is designed for use in SCADA systems mainly based upon power utility communication networks. Depending on modulation standards it can communicate through specialized, private or leased lines, radio links and power lines (PLC) The IG202T-R38 is available as a desktop modem or in two different types of standard 19" rack, including: 1U rack with 1, 2, or 3, modems per rack; 3U rack with 10, 23, or 14 modems per rack, with additional blank front plates covering unused slots.

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