Cascade Low Power Data Modem (CDM) for extreme temperatures

The Cascade Modem is designed to operate reliably in harsh conditions. It serially connects (RS-232) with any data-collecting or electronic device that is battery, solar or AC powered.

Unlike the average “off the shelf” modem, the Cascade Modem is designed to work in high heat and humidity and in freezing cold temperatures alongside the road in dusty cabinets. It will dependably transmit data and control commands and has a temperature range of –40 to +85 C (-40 to +185 F).

Powering down to 170 micro amps (.001 watts) while awaiting the next call, the Cascade Modem uses far less power than most other modems, which draw as much as 35 milliamperes, or over 200 times as much power. In practical terms, this means a standard “off the shelf” modem requires a 10-watt solar panel while the CDM needs less than one watt of solar power.

The CDM can be interfaced with traffic classifiers, weigh-in-motion sites, weather stations, variable message signs, oil wells, pipelines etc. It is also hardened against lighting and has an external earth grounding to aid in static electricity suppression.

Features
Low power (uses 200 times less than the average modem)
Wide temperature operating range (-40°f to 185°f)
Automatic power-up and power-down
Lighting and ESD protection with static electricity suppression
LED status indicator
One Blink every fifteen seconds indicates unit is operational and is in power save mode.
Continuous blinking indicated ring signal or RS232 activity detected.
Continuous on indicates carrier detected and data being transmitted.
Optional ring activated relay
an optional ring delay can be added to the modem circuitry that actuates a normally open or closed contact for 1 second each time the modem is called. This isolated contact may be used to trip or activate any secondary device.
