Rutter Data Management Module, RUT-02590-DA DMM G2

The Rutter Data Management Module (DMM) G2, part number RUT-02590-DA, is a core component of the Rutter 100G2 Voyage Data Recorder (VDR) system. Its primary function is to collect, process, and manage various critical data streams from a vessel’s sensors and systems (e.g., radar, ECDIS, GPS, audio) for continuous recording by the VDR. Essentially, it acts as the central intelligence unit for the VDR, ensuring compliant and reliable storage of maritime operational data for accident investigation and analysis.

Technical Specification

General Role & Compatibility:

Product Type: Data Management Module (DMM) for Voyage Data Recorder (VDR) systems.
System Compatibility: Specifically designed for Rutter 100G2 and 100G2S VDR systems. It is the successor to the RUT-00412-DA DMM.
Function: Processes, manages, and records various data inputs from ship systems (audio, video, serial data like NMEA), and interfaces with the Final Recording Medium (FRM/SFRM) and other VDR components.

Power Requirements:

Input Voltage: The RUT-02590-DA DMM G2 typically operates on 12V DC. It’s important to note that when replacing older DMM models (like RUT-00412-DA which required 24V DC), a 24VDC to 12VDC line conditioner/power converter (e.g., RUT-07001) is required and often included in replacement kits. This converter ensures compatibility with the existing 24VDC power infrastructure of the VDR system.

Interfaces & Data Handling (as part of the VDR system):

Audio Inputs: Capable of handling multiple audio channels from microphones (e.g., bridge, VHF Tx/Rx).
Video Inputs: Designed to capture video data from radar, ECDIS, and CCTV displays at defined intervals.
Serial Data Inputs (NMEA): Processes ASCII serial data from various ship sensors (GPS, gyro, speed log, etc.) via NMEA modules (e.g., RUT-01029-AA NMEA Module for RS422/232).
Ethernet: Utilizes Ethernet for internal communication within the VDR system (e.g., with Data Acquisition Units, Data Processing Units, and for data download).
USB: Supports USB memory sticks for data download and transfer.
Internal Storage: Likely contains internal storage (e.g., solid-state drive or hard disk drive) for temporary data buffering and processing before it’s transferred to the long-term protected recording medium (FRM/SFRM).
Communication: Communicates with the Operation and Alarm Unit (OAU) and other VDR modules.

Physical & Environmental Specifications:

Form Factor: Designed to fit within the Rutter 100G2 VDR Data Processing Unit (DPU) housing. Specific dimensions and weight are not readily available for the DMM module itself but are constrained by the DPU’s enclosure.
Cooling: Equipped with a fan (e.g., RUT-02147 for the DPU) for internal cooling.
Environmental Standards: As a marine electronic component, it is designed to meet international maritime standards for shipborne equipment, primarily IEC 60945 (Maritime navigation and radio communication equipment and systems – General requirements – methods of testing and required results) and IEC 61996 (Shipborne Voyage Data Recorder – Performance requirements – methods of testing and required test results). This implies:
- Operating Temperature: Typically -15°C to +55°C (though specific component ratings might be tighter).
- Storage Temperature: Typically -25°C to +70°C.
- Humidity: Operating humidity ranges (e.g., up to 95% non-condensing).
- Vibration and Shock: Designed to withstand shipboard vibration and shock levels.
- EMC (Electromagnetic Compatibility): Complies with relevant EMC standards to prevent interference with other ship systems.

Software:

Operating System: Often runs on a Windows operating system (a Windows license key is included in replacement kits).
Firmware/Software: Runs Rutter’s proprietary VDR recording and management software.
