2. PRODUCT OVERVIEW
The MIUPowerPortX.X Series are industrial grade dial and leased line
modems for connection to the Public Switched Telephone Network.. They
can be powered from a wide range of AC and DC power supplies, they are
internally surge protected on both the power and analog lines, and they will
operate in temperatures from -40 to +85 deg C.
Internally, each unit 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™ Dial Modem Module.
The MIU PowerPort is packaged specifically for the harsh environments
found in utility substations, industrial facilities and remote sites. Though
functionally similar to commercial modems, the MIU PowerPort includes
special features that make it particularly well suited for utility and
industrial applications:
Environment: The MIU PowerPort has been designed specifically
for use in harsh environments. In addition to an
extended temperature range (-40 to +85º C), the MIU
includes surge, shock, vibration, and safety features
superior to those of conventional commercial
modems.
Power Supply: The MIU PowerPort can be powered from a range of
AC and DC power sources: +5 VDC, 12 VDC Battery,
7 to 16 VAC or 8 to 16 VDC. An optional 120 VAC
wall transformer is available from Telenetics.
Low Power: The MIU PowerPort dial modems can be configured
to enter into a “power down” mode. In this mode, an
MIU PowerPort will consume only a small fraction of
its active power while waiting for either controller or
telephone line activity.
