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
Express™ PE202T 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.
