CZone NMEA 2000 Network Bridge Interface Module

Advanced Network Isolation and Seamless CAN Bus Bridging

Managing complex marine and mobile electrical architectures requires precise control over both data flow and power consumption. The CZone NMEA 2000 Network Bridge Interface Module is a dedicated system communication gateway engineered to optimise how your digital switching and navigation systems interact. By acting as an intelligent barrier between different segments of your network, this module allows system designers to isolate sections of an NMEA 2000 backbone or seamlessly bridge two independent Controller Area Network (CAN) systems, such as connecting a CZone digital switching setup to a Simrad SimNet navigation network.

Reduce Standby Current Draw and Preserve Battery Banks

One of the primary challenges in modern marine and off-grid RV installations is managing parasitic power drain when the vessel or vehicle is not in active use. Standard NMEA 2000 networks often keep all connected devices powered simultaneously, which can rapidly deplete house battery banks. This Network Bridge Interface Module solves this issue by physically and electrically isolating specific segments of the network.

For example, you can power down high-draw navigation instruments, radar arrays, and helm displays when anchored or parked, while keeping essential CZone monitoring, bilge controls, and security circuits active on the primary network. This targeted isolation significantly decreases standby current draw without sacrificing critical system functionality or requiring complex manual switching.

Overcome NMEA 2000 Node Limitations

As onboard technology expands, larger vessels and custom recreational vehicles frequently hit the physical limits of standard network architectures. A typical NMEA 2000 backbone has strict limitations on the number of devices (nodes) it can support before signal degradation and voltage drop occur. When an existing network reaches its maximum node limit, installing this bridge module immediately expands your system capacity, allowing up to 40 additional nodes to be integrated safely.

• Dual 5-Pin Connectors: Features dedicated ports for Network 1 and Network 2, enabling straightforward plug-and-play integration between separate CAN or NMEA 2000 backbones.
• 40-Node Expansion Capacity: Effectively doubles the capability of a maxed-out network section by supporting up to 40 extra connected devices.
• Intelligent Power Isolation: Separates network power buses to significantly lower parasitic standby drain during storage or standby modes.
• Cross-Platform CAN Bridging: Facilitates reliable data communication between distinct protocols, such as bridging CZone and Simrad SimNet architectures.
• Onboard Diagnostic LED: Includes a clear status indicator displaying real-time network health and activity across both connected CAN segments.
• Robust Marine Construction: Built with integrated corner mounting points for secure, vibration-resistant installation in demanding marine and mobile environments.

Engineered for System Reliability and Risk Reduction

Relying on improper splices or unverified third-party adapters to join two CAN networks introduces significant risks, including data collisions, ground loops, and complete communication blackouts at sea or off-grid. The CZone Network Bridge utilizes internal isolation circuitry to protect both sides of the network. While allowing essential operational data and PGNs to pass through seamlessly, it prevents electrical faults or power drops on one backbone from compromising the stability of the connected network. The integrated diagnostic status LED provides immediate visual confirmation that both segments are communicating properly, simplifying commissioning and fault-finding for marine electricians and system integrators.
