Detailed description

The B&G H5000 CPU Hydra processor (reference 000-11545-001) is the central unit of the H5000 navigation instrument system. Designed to centralize and process data from onboard sensors, it is equipped with dual ARM processors offering up to 50 times faster computing speed than the previous generation. This module ensures the distribution of accurate, real-time information to displays, the autopilot, and external applications.

Positioning within the H5000 range

Within the B&G processor series, the Hydra version differs from the Hercules and Performance models. While the Hercules and Performance CPUs target high-level regattas and complex offshore racing sailboats (with advanced 3D motion sensor management and polar tables), the H5000 Hydra is specifically calibrated for offshore cruising sailboats and cruiser-racer vessels. It delivers B&G’s reliability and calculation algorithms without the complexity of extreme racing configurations, positioning itself against competitors like the NKE Regatta with its simplified configuration interface directly integrated via a web server.

Connectivity and hardware interfaces

The Hydra CPU integrates comprehensive connectivity to adapt to modern and existing marine networks. It features one NMEA 2000 Micro-C port (1 LEN) and two bidirectional NMEA 0183 ports with selectable message configuration. Local network connection is provided by an Ethernet RJ45 port (100 Mbit) enabling access to the web server for setup, calibration, and diagnostics from a PC, tablet, or smartphone. The housing also includes a dedicated USB port for software updates. For sensors, it offers a direct interface for B&G wind sensors, a speed-through-water input (0-5V TTL), four configurable analog inputs (0-5V), a dedicated input for a man-overboard (MOB) button, and a digital alarm output. Front-panel LEDs provide at-a-glance system status.

Computing performance and navigation features

This processor integrates a high-performance wind filter ensuring stable data transmission to displays and the autopilot computer. Embedded algorithms manage wind correction based on heel and trim angles, true wind correction, and calculations for leeway and current. AutoCal routines simplify sensor calibration. The advanced MOB function calculates the estimated relative position by integrating tide data, with dynamic updates possible via AIS SART beacons. The system supports composite SailSteer displays, Startline tools, and wireless data broadcasting via GoFree by adding an optional router.

Physical and electrical specifications

The central unit measures 211 mm in width, 196 mm in height, and 66 mm in depth, weighing 0.7 kg. Designed for below-deck installation in a dry environment, the housing meets IPX5 waterproofing standards. It operates on a nominal 12V DC power supply (operational voltage range 9 to 16V DC) with a recommended 5A fuse. Its operating temperature range is -10°C to +55°C.

« The H5000 Hydra central processing unit: the core of your B&G navigation system »

The B&G H5000 CPU Hydra is the cornerstone of the H5000 instrument system, essential for any cruising or racing sailboat requiring reliable and precise navigation data. With its dual ARM processors, this central unit ensures real-time data acquisition and processing, critical for rapid decision-making at sea. Its ability to integrate a wide range of sensors via NMEA 2000, NMEA 0183, and Ethernet makes it a versatile and robust data hub.

The strategic advantage of the CPU Hydra lies in its balance between advanced features and accessibility. It provides the necessary wind corrections for sail trimming and starting line tools, key functions without the complexity of 3D polar calculations found in Hercules or Performance versions. Access to the integrated web server via Ethernet greatly simplifies installation, calibration, and diagnostics, enabling fine-tuning of the system from any browser. While certified to IPX4 and designed for below-deck installation, its compact design and low weight (0.7 kg) facilitate integration into tight technical spaces. It is a wise choice for a high-performance and scalable H5000 system base.

What is the primary function of the H5000 CPU Hydra processor?

The H5000 CPU Hydra is the central processing unit, the brain of the B&G H5000 instrument system. Its function is to centralize, process, and compute in real time all data from the connected sensors (wind, speed, depth, heading, etc.) to provide accurate and responsive navigation information.

Which data networks is the H5000 CPU Hydra compatible with?

The H5000 CPU Hydra processor is compatible with multiple networks for full integration:

NMEA 2000 (via a Micro-C port) for connection to the boat's main network.NMEA 0183 with two bidirectional and configurable ports.Ethernet (via an RJ45 port) for access to the configuration web server and connection to other systems.

Where should I install the H5000 CPU Hydra processor aboard?

The H5000 CPU Hydra must be installed in a protected and dry location below deck. Its housing has an IPX5 protection rating, shielding it from low-pressure water jets, making it suitable for installation in a bilge or locker, away from direct weather exposure.

What is the difference between the Hydra CPU and the Hercules or Performance versions?

The H5000 Hydra CPU is the entry-level processor in the H5000 range. It provides all essential functions for cruising and regattas.
