Introduction
Thank you for purchasing Data Connect IG202T and IGV23 leased line modem,
the finest industrial-grade modem available. This manual will cover both the standalone
IG202T, a Bell 202 compatible, and the standalone IGV23, an ITU-V23 compatible modems.
The Data Connect
wire, full-du
The modem is designed utilizing the stand FSK modulation technology to achieve high
performance and low cost.
The IG202T/V23 modem is ideally suited for multi-point communication systems that require
fast response time, short training time, and low throughput delay.
This User’s Guide describes the IG202T/V23 (AC-powered) and IG202T-DC/V23-DC (DCpowered) stand-alone modems, as well as the rack-mount IG202T-RM plug-in module for
the Motorola/UDS RM16M. This manual is designed to get your modem “up and running” as
quickly as possible. It contains all the information you need to configure and install your
modem. It also contains troubleshooting information in the unlikely event you encounter a
problem with your modem.

Introduction
Features
The IG202T/V23 modem is specifically designed for harsh environments typically associated
in utility substations and industrial facilities. Though functionally similar to commercial
modems, the IG202T/V23 provides the following unique features that make it well suited for
utility and industrial applications.
y Packaged in a rugged, compact enclosure for industrial applications.
y Leased-line interface protected with heavy-duty surge protection devices.
y Built-in hardware watchdog timer for software lock-up prevention without
requiring human intervention, making it ideal for unmanned locations.
y Works within an extended temperature range of -40ºC to +85ºC.
y Designed with coupling transformers for high-voltage isolation and common
mode noise rejection in industrial and commercial environments.
y Operate over voice-band conditioned or unconditioned leased-line and pilot
wires.
y Accepts power from a wide range of AC and DC power supplies:
– IG202T/V23: 90 to 265 VAC or 100 to 400 VDC
– IG202T/V23-DC: 10 to 60 VDC
– IG202T/V23-RM: Plug-in module for the Motorola/UDS RM16M modem nest
y Standard industrial connectors for data, analog, and power interfaces allow
reliable interconnection to other industrial equipment.
y Asynchronous data rates 0-1200 bps.
y Easily accessible DIP switches for user configuration and option selection.
y DB9-F connector for RS-232/V.24 interface, and RJ-11 for RS-485.
y Local analog, local digital, and remote digital loopback diagnostics.

There are a number of factors that can affect the modem’s operation and performance.
These include:
y Modem speed (i.e. bit error rate, transmission line distance)
y 2-wire or 4-wire configuration
y Transmission line characteristics, noise, and line impairments
y Transmission cable length (pilot wire)
y Network configuration (point-to-point or multipoint)
