Yacht Devices YDNB-07 NMEA 2000 Bridge

Yacht Devices YDNB-07 NMEA 2000 Bridge

The Yacht Devices YDNB-07 NMEA 2000 Bridge seamlessly unifies two physical NMEA 2000 networks into a single logical network, ensuring smooth message exchange between them. It also supports filtering and processing of transmitted messages, providing robust network management capabilities.

Extend and Manage Your Network

The YDNB-07 Bridge helps you bypass the physical limits of NMEA 2000 networks, such as the maximum length (100 meters for regular cable, 250 meters for heavy or mid-type cable) and the maximum number of physical devices (50). With an address capacity of 252, multiple bridges can be used to expand the network to accommodate up to around 250 physical devices. It also allows for isolating devices from each other by blocking transmission of selected messages from a given device in a separate subnet.

Compatibility and Functionality

This device ensures the proper functioning of equipment by correcting the transducer offset of the depth sounder or "deleting" invalid data from partially operational equipment using a simple 2- or 3-line script. It also facilitates compatibility between equipment from different generations, enabling the creation and transmission of any type of NMEA 2000 message using data from other network messages.

Advanced Diagnostics and Programming

The Bridge can diagnose network malfunctions by recording messages and debugging data from custom programs onto a MicroSD card in a text file format. These files can be viewed on a smartphone or tablet with a MicroSD slot, eliminating the need for a computer. Additionally, you can create and edit programs for the Bridge directly on your phone. Free diagnostic software is available for Microsoft Windows, Mac OS X, and Linux, allowing you to play, view, and convert binary log files with NMEA 2000 messages from both CAN interfaces.

Safe and Flexible Connections

One of the CAN interfaces on the device offers high-voltage galvanic isolation and can operate at higher supply voltages, allowing safe connections for devices that do not meet NMEA 2000 standards. The Bridge can also create gateways for networks based on the CAN protocol operating at speeds of 50, 125, 250, 500, and 1000 kbps, although the programming language of the device is not intended for full-fledged applications.

Technical Specifications

• Two connectors (CAN1 and CAN2) compatible with Raymarine SeaTalk NG or NMEA 2000 Micro Male
• Expandable network capacity up to around 250 physical devices
• High-voltage galvanic isolation on one CAN interface
• Power consumption: 38 mA (CAN1), 13 mA (CAN2)
• Cable length between interfaces: 0.5 m (20 in.)

Programming and Diagnostics

The Bridge contains a built-in compiler for a simple programming language, allowing you to create programs on any device with a MicroSD socket and text editor. Programs can be uploaded to the Bridge using a MicroSD card. The device can log all NMEA 2000 messages and program variables to a text file on the MicroSD card and save messages from both interfaces to binary log files (.CAN format), which can be viewed and converted with the free CAN Log Viewer tool.
