Original Press Release:

Computer Modules, Inc. Launches Cockpit Audio Recorder for Accident Investigations Aboard Mass Transit Vehicles

CockpitRecorder 6™ Designed for OEMs Who Build Data Systems for Use Aboard Trains, Buses, Ferries, Mass Transit, Military Vehicles, and Other Moving Vehicles Subject to Accidents Caused by Operator Errors, etc.

San Diego, California – Computer Modules, Inc. (CMI), a trusted supplier to systems integrators for over 25 years, is pleased to introduce their innovative audio recorder specifically designed for capturing the last six minutes of audio prior to a trigger event. The new CockpitRecorder 6™ unit can withstand an impact of high G’s and a wide range of operating temperatures.

The recorder was designed to back up audio interactions within mass transit systems and is designed to operate in harsh environments.  Since the recorder has no moving parts, setup is simple.  

It is an "Always On" device requiring audio input and a trigger button connection.  Even after a sudden loss of power the unit will back up the last six minutes of audio to nonvolatile memory.

The unit is designed for post crash or post event examination purposes.

"The CockpitRecorder 6 is capable of continuously recording over a period of years.  When a trigger event happens or power is removed, the unit stops recording and retains the last six minutes of recorded sound with excellent audio quality," commented Laszlo Zoltan, Vice President of Computer Modules, Inc. "This recorder is ideal for transportation, military, and aviation systems, or as a radio communications recorder. We have also implemented many functions to meet our customers' special needs."
