The Data Connect low speed IG-202T/V23 modem is designed and manufactured for rugged industrial communication networks. It is the most industrial grade 202T & V23 modem on the market operating from -40C to 85C (185F). The IG-202T/V23 modem delivers cost effective and reliable 1200bps asynchronous solutions for point to point and multipoint connectivity. For optimum performance, the modem employs FSK modulations to be compatible with Bell-202T and ITU-V23 standards and communicates over a variety of transmission lines.
The IG-202T/V23 modem is ideal for industrial communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial and automation networks. The
IG-202T/V23 modem supports RTUs with switch selectable settings and no software code commands. The IG-202T/V23 modem is designed to operate 4-wire full duplex or 2-wire half duplex over, Special Access Service VG6 that is a 4-wire channel suitable for the access segment of most voice grade data circuits, unconditioned leased lines, or private metallic circuits.
The IG-202T/V23 modem can operate over a wide range of AC or DC power supply voltages and temperatures. With proven reliability and ease of installation the IG-202T/V23 is ideal for point-to-point and point-to-multipoint polling networks, where reliability and low-network latency are critical for system performance. The IG-202T/V23 modem has internally Flow Control options of "Constant On" and "Controlled by RTS". The Flow Control options are Dip-Switch selectable and the options performs the same functionality as DataSense or other flow control and buffering schemes. 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/V23 industrial grade Bell 202/V23 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/V23 is provided by DIP switches and jumpers,
eliminating the need for an AT command set. Unlike any other 202T/V23 modem you can buy, the IG202T/V23 has heavy-duty surge protection at the power supply and leased line inputs. IG202T/V23 also uses an isolated DC to DC power converter for protecting critical DC or battery power systems.
