1.1.1 Data Processing Unit (DPU)
The
Data Processing Unit
(DPU) receives and processes information provided from the various Audio,
Video, and NMEA Input Modules. This information is processed in the Data Management Module (DMM)
for archiving on the DMM’s internal hard drive, the Final Recording Medium (FRM), USB Memory Stick,
and the optional Remote Storage Module (RSM).
The VDR-100G2 power system is housed in the DPU, and accepts universal AC or 24VDC from the
ship’s emergency power while providing 24VDC to the VDR-100G2 modules. The power system includes
batteries to provide uninterrupted power to the audio recording system in the event of a blackout.
The DPU also contains an Ethernet switch (hub) which provides the ability to combine video and NMEA
data into a single Ethernet link.

1.1.1.1 Data Management Module
The
Data Management Module
(DMM) is a rugged, small form factor Pentium computer. It is equipped
with four (4) Ethernet input ports, two (2) serial ports, two (2) USB ports, a high capacity hard disk drive,
and a compact flash card containing an embedded Windows XP operating system.
The module compresses and stores data received from the acquisition modules and, simultaneously,
outputs processed data to the FRM, USB Memory Stick, optional Remote Storage Module (RSM), and
optional Download/Playback PC (as described below).
Communication with the Operation and Alarm Unit (OAU) and Power Control Module (PCM) occurs via
the serial ports. Additionally, the DMM can be configured to provide data for real-time display via an
Ethernet connection.
In addition to the most current data set, the base model DMM can store numerous previously recorded
full data sets in a secure location. This secure location prevents previously recorded data sets from being
overwritten.
