Industrial Grade Bell 202T  and or V.23 Modem

The IG-202T and IG-V23 modems are designed and manufactured for rugged industrial communication networks. Both modems deliver cost-effective and reliable 1200 bps asynchronous solutions for point-to-point and multipoint connectivity. The IG202T/V23 modems are ideal for industrial communication applications including SCADA systems, RTUs, traffic monitor and control, and industrial automation networks. The IG202T/V23 supports RTUs with a user-selectable EIA RS-232 or RS-485 serial port at speeds up to 1200 bps. The IG202T/V23 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 202T and ITU-V23 standards, which can communicate over a variety of transmission lines. The IG202T/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 IG202T/V23 is ideal for point-to-point and point-to-multipoint polling networks, where reliability and low-network latency are critical for system performance.

Chassis ground and signal ground of the modem are not connected. 

Chassis ground is only connected through the shell case of the DB-9F connector to the DTE.

This ground is used only for surge voltage returns. 

The AC neutral is not connected to the modem’s chassis ground.
