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.
