1.STANDARDS

Meets FCC Rules Part J, Subpart 15, Class A for radiated emissions.

2.PRODUCT OVERVIEW

The MIU202T is an industrial grade Bell202T modem for connection to unconditioned and conditioned, voice grade, type 3002 two or four-wire leased lines and metallic lines (eg; pilot wires). It can be powered from a wide range of AC and DC power supplies, it is internally surge protected on both the power and analog lines, and it will operate in temperatures from -40 to +85 deg C.

Internally, the MIU202T consists of a baseboard and a communication module. The baseboard includes the power supply regulation and surge protection. The communication module is a Telenetics™ Pony ExpressPE202T Modem Module.

The MIU202T is packaged specifically for the harsh environments found in utility substations and industrial facilities. Though functionally similar to commercial modems, the MIU202T includes special features that make it particularly well suited for utility and industrial applications:

Environment: The MIU202T has been designed specifically for use in harsh environments. In addition to an extended temperature range (-40 to +85º C), the MIU202T includes surge, shock, vibration, and safety features superior to those of conventional commercial modems.

Power Supply: The MIU202T can be powered from a broad range of AC and DC power supplies, such as an auxiliary supply (eg; 12VDC) from another piece of equipment, 125VDC from a station battery or a standard 120VAC.

Industrial: The MIU is packaged in a rugged, compact, non- metallic (ABS) enclosure. Designed for unmanned locations, the MIUs do not include the array of pushbuttons and LEDs normally associated with consumer-type modems. Configuration is by dip switches. Standard industrial connectors for data, analog and power interfaces allow reliable interconnection to other industrial components.

This flexibility ensures that it can be seamlessly integrated into existing systems, facilitating both legacy and modern installations.

The MIU202T also boasts advanced modulation techniques, utilizing Frequency Shift Keying (FSK) and Phase Shift Keying (PSK) to enhance data integrity over long distances. This means that whether operating in urban, suburban, or remote areas, the modem maintains a stable connection, ensuring that data transmission is reliable under diverse conditions.

In terms of operational range, the Telenetics MIU202T modem excels, offering capabilities to transmit data over several miles. This is particularly beneficial for industries such as water management, oil and gas, and environmental monitoring, where assets are often located far from central control systems. The modem’s high sensitivity receiver and power management features contribute to its outstanding performance in distant communication scenarios.

Another key characteristic of the MIU202T is its durability. Constructed to withstand harsh environmental conditions, this modem is designed with rugged enclosures and operates effectively across a wide temperature range. This resilience makes it suitable for outdoor installations where temperature fluctuations, moisture, and dust could compromise other equipment.

Power efficiency is yet another highlight of the MIU202T. With low power consumption, it is ideal for battery-operated systems and remote installations, reducing the need for frequent maintenance and battery replacement. Additionally, its built-in intelligence allows for automatic power management, ensuring optimal operation while conserving energy.

In conclusion, the Telenetics MIU202T modem stands out for its robust communication capabilities, advanced modulation technologies, operational range, durability, and power efficiency. These features make it a prime choice for industries requiring reliable remote data transmission and telemetry solutions. Whether for monitoring environmental parameters or managing utility services, the MIU202T is equipped to handle the demands of modern industrial communication.
