MIU9.6FPD Installation, Operation & Diagnostics April 25, 1998 Page 3
2. PRODUCT OVERVIEW
The MIU9.6FPD is an industrial grade Digital Fast Poll modem designed
for multidropping applications over unconditioned metallic lines (eg;
pilot wires). Available as single channel device (MIU9.6FPD), 2-channel
device (MIU9.6FPD/D) or repeater (MIU9.6FPD/R)
The MIU9.6FPD 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 MIU9.6FPD 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™ PE9.6FPD Modem Module.
The MIU9.6FPD is packaged specifically for the harsh environments
found in utility substations and industrial facilities. Though functionally
similar to commercial modems, the MIU9.6FPD includes special features
that make it particularly well suited for utility and industrial applications:
Environment: The MIU9.6FPD has been designed specifically for use
in harsh environments. In addition to an extended
temperature range (-40 to +85º C), the MIU9.6FPD
includes surge, shock, vibration, and safety features
superior to those of conventional commercial modems.
Power Supply: The MIU9.6FPD 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 MIU9.6FPD 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.
