Industrial Grade 202T Modem

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.

Reasons to Buy the IG202T Modems

The IG202T Industrial Grade Bell 202 Modem
IG202T Industrial Grade Modem is the most dependable and easy to install Bell 202 compatible leased line modem available today

The IG202T modem was designed to be compatible with the Bell 202T standards which was established in the 1970s by the Bell Laboratory. The modem standards has been adapted by many modem manufacturers and has not been changed in the last 30 years. The IG202T was designed to meet the highly dependable and reliability demand by the utility and industrial applications.

The IG202T modem is 100% compatible with the Bell 202T standard modems.

The IG202T is implemented with the latest VLSI technology to replace the old designs that were 20 years or older products. By using VLSI, component count of the IG202T is much lower, which lowers the failure rate and increase the modem’s mean time between failure (MTBF)

The IG202T modems are built with industrial grade components and will operate over the temperature range of -40 to +85 degree C. The UDS/MOT202T were build with general commercial grade components and is guarantee to operate from 0 to +50 C only.

The IG202T has additional features (i.e. auto RTS) to support SCADA equipment that does not provide the full RS-232 or RS-485 control signals.

The IG202T equipped with 3 different types of surge protection devices to guard against its power supply input and leased line interface.  The surge protection for the MOT202T has been minimum to non-existence.

The new modem has a much smaller foot-print than the MOT202T modems.  The IG202T is about 30% the size of the MOT202T, and consumes less power. Because of its low power consumption, it is now possible to operate the modem in battery or solar powered environment

The new modem will support 10 to 60 volts DC power supply, or can be powered by a factory provided AC to DC converter from 100 to 240 VAC or 100-400VDC.  This will reduce customer’s inventory of modems and saving cost by stocking only one model instead of two models.

The IG202T modems support both RS-232 and RS-485 interface.

The IG202T is designed with a microprocessor controller on-board, it minimized the use of DIP switch or jumpers settings, which simplify installation and cut down potential errors.

The IG202T modems can be rack-mount (IG202T-RM), panel or wall-mounted, or DIN rail mounting with the optional DIN rail mounting kit.

The rack-mount version will fit into the original Motorola RM16 chassis or the new RM16 chassis.


The engineers who designed the original MOT202T modem no longer support or enhance the modem.  They have changed companies and have designed the IG202T modems.  The engineers who designed the IG202T modem are available to support applications and technical issues only for the IG202T modems.  They will stand behind the product and support of the IG202T modems for any future applications, update and enhancement.  No update or enhancement is expected to be provided by the old 202T products.  Problem solving and the ability to support new applications will be found only in the new IG202T products. 

Support will be provided for repair, to diagnose and analyze your installation, network connections and equipment.

Technical support will be provided to ensure optimum performance with your network and potentially save time and cost in your operation.

Customize the product hardware and firmware to meet your specific applications or enhance your system performance.

The Bottom Line

Why buy an old product that was designed over 20 years ago that might face the possibility of obsolete components with questionable reliability which might affect the integrity of your network performance? The IG202T is specifically built for harsh environment and is most reliable for industrial applications that will be saving cost in the long run.
