Description

The Data Connect low speed IG202T Industrial Grade Bell 202 modem is designed and manufactured for rugged industrial communication networks. The IG202T delivers cost effective and reliable 1200bps asynchronous solutions for point to point and multipoint connectivity. 

The IG202T Industrial Grade Bell 202 modem is ideal for industrial communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial and automation networks. The IG202T supports RTUs with switch selectable settings and no AT command set required. The IG202T modem is designed to operate over 4-wire full duplex or 2-wire half duplex over unconditioned leased lines
or private metallic circuits. For optimum performance, the modem employs FSK modulations to be compatible with Bell 202 standards, which can communicate over a variety of transmission lines. The IG202T Industrial Grade Bell 202 modem can operate over a wide range of AC or DC power supply voltages and temperatures. With proven reliability and ease of installation the IG202T is ideal for point-to-point and point-to-multipoint polling networks, where reliability and low-network latency are critical for system performance. With its Auto-RTS mode, the modem can support DTE/RTUs with 3-wire serial interface (TD, RD, SG) in point-to-point and multi-point polling applications.

The IG202T industrial grade Bell 202 modem has selectable EIA RS-232/V.24 and RS-485 DTE support. It also features built-in diagnostics for local and remote testing. The configuration and options on the IG202T is provided by DIP switches and jumpers, eliminating the need for an AT command set. The IG202T has heavy-duty surge protection at the power supply and leased line inputs. IG202T also uses an isolated DC to DC power converter for protecting critical DC or battery power systems.
