Headway VDR Interface SPEED LOG 1 To 26 Log Interface

Headway VDR Interface SPEED LOG 1 To 26 Log Interface

The Headway VDR Interface for Speed Log is an essential data concentration and protocol conversion unit designed to ensure your Voyage Data Recorder (VDR) or Simplified Voyage Data Recorder (S-VDR) receives accurate and uninterrupted data from critical navigation sensors.

This robust interface acts as a central hub, specifically engineered to acquire, process, and convert speed log data—along with inputs from a wide array of other shipboard sensors—into the standardized IEC 61162-1/2 format required by your VDR system. It is the reliable bridge that guarantees compliance with stringent IMO performance standards.

Key Features & Benefits

• Comprehensive Data Acquisition: Connects and interfaces with up to 26 discrete data sources, including your primary and secondary Speed Logs, GPS, Gyrocompass, Anemometer, Echosounder, and more.

• Multi-Protocol Support: Features versatile input capabilities for both NMEA 0183 and NMEA 2000 networks, ensuring compatibility with virtually all modern and legacy navigation equipment onboard.

• Robust Protocol Conversion: Intelligently converts all incoming proprietary or standard NMEA sentences into clean, compliant IEC 61162-1 or IEC 61162-2 output signals, perfectly formatted for your VDR.

• Enhanced Data Integrity & Reliability: Built with marine-grade components and advanced processing to filter noise, validate data, and provide a stable signal, crucial for the accuracy of the VDR’s recorded data.

• Simplified Installation & Integration: A plug-and-play solution that drastically reduces the complexity and time required to integrate multiple sensors with your VDR system. Clear labeling and standard connectors facilitate easy setup.

• Fail-Safe Design: Engineered for continuous operation in the harsh marine environment, featuring high immunity to electromagnetic interference and stable performance in varying temperature and humidity conditions.

Primary Applications

This interface is indispensable for:

• New VDR/S-VDR Installations: As a core component of the data acquisition system.

• Retrofits and Upgrades: Modernizing existing bridge systems and ensuring legacy sensors can communicate with new VDR equipment.

• Compliance Assurance: Providing a certified and reliable method to meet IMO MSC.333(90) regulations regarding data recording from mandatory sources.

• System Troubleshooting: Acting a clear demarcation point for diagnosing communication issues between sensors and the VDR.
