Product Information

NMEA and Digital Switching

NMEA is a communication protocol used in marine electronics. Digital switching is a new alternative to traditional electromechanical switching that provides improved safety and reliability while reducing vessels down time, operator’s workload, overall vessel weight and wiring complexity.

CLMD12 Digital Switching Module

The CLMD12 is a digital switching module that can be used to switch breaker states or as inputs for other data such as bilge alarms or hatch positions. It provides low loss solid state On/Off functions, accurate current measurement, short circuit protection, and pulse width modulation (PWM). It has a product specification of 1A increments and can be wired easily.

CBMD12 Manual Bypass Module

The CBMD12 is a manual bypass module that can be used in conjunction with the CLMD12. It provides manual control of the loads in case of system failures.

Electromechanical vs Digital Switching

Digital switching provides less wiring distance by centralizing power distribution, space-saving, reduced cost, service provided via real-time cloud service, timers, and paralleled channels.

Before You Start Your Design

Before starting your design, it is recommended to map an NMEA2000 network, create a Bill of Materials (BOM), and understand the limitations that lead to common errors.

Product Usage Instructions

Follow the instructions in the user manual to install and wire the digital switching modules, manual bypass module, rocker multiplexed switch module, and button keypad. Use the product specifications to ensure appropriate usage of each module, ensuring accurate current measurement, short circuit protection, and pulse width modulation (PWM). Consider using digital switching instead of traditional electromechanical switching for improved safety, reliability, reduced downtime, and overall ease of use. Before starting your design, map an NMEA2000 network, create a Bill of Materials (BOM), and understand the limitations that lead to common errors.

NMEA2000® INTRODUCTION

What is NMEA?

• NMEA: Which stands for National Marine Electronics Association, is an organization committed to enhancing the technology and safety of marine electronics through installer training and interface standards.
• NMEA2000®: A plug-and-play communications standard used for connecting marine sensors and display units within ships and boats
• Plug and Play: Intended to work perfectly when first connected, without reconfiguration or adjustment by the user (pretty much)
• Communication runs at 250 kilobits-per-second and allows any sensor to talk to any display unit or other device compatible with NMEA2000® protocols

DIGITAL SWITCHING

A New Alternative

• Digital Switching Systems can replace traditional mechanical switches and circuit breakers on board a boat with Digitally Controlled Power Distribution Modules
• Power Distribution Module: Power Distribution Modules are customised to meet the exact needs of the system being controlled, and communicate using NMEA2000® networks. An example of a Power Distribution Module is our CLMD12 or CLMD16.
• All hardware in a Digital Switching System is given a unique number called a Device Instance, which allows a Power Distribution Module or Digital Switching Module to be identifiable over an NMEA2000® network. Using this Device Instance, all the devices can communicate and be used to perform user defined tasks
