Even the most basic marine electronics system has some form of data network to enable devices to communicate with each other. During the course you will learn about all the various network protocols in great detail from the basic voltages and pulses to the bits and bytes that make up the data. Old, new, and future planned standards are included such as NMEA 0183 V1, V2, NMEA 2000, Sea Talk, OneNET and more.
Many marine engines and outboards now have Engine Control Units, making the process of interfacing this data with the vessels data easier. However even basic engines with no electronics can still be rigged up to join the party. During the course you will learn how to display engine parameters from any engine, including onboard tank levels, in fact virtually anything that can be measured can be displayed on a Multi Function Display, tablet, or phone.
Learn about all the radio systems you could find onboard including VHF, MF, HF, SSB, Radar, AIS, GNSS, Navtex, Satellite, and GSM - in great detail. You will learn about cabling and connector requirements between these devices and their antennas, calculating line losses, and testing signal loss. This is a complex area of marine electronics and requires many more considerations than traditional cabling.
Gain a detailed insight into how all the onboard transducers transform one type of energy into an analogue, and then onto a digital NMEA signal. There are a number of various ways information can be gathered, distributed and centralised within a marine electronics system, and during your course you will learn how each system accomplishes its objectives within a myriad protocols dating from the 1980s to the latest cutting edge technology.
There is a huge choice of Multifunction devices available to display the vessels data - but very few can display every parameter available. Ensuring any devices you buy actually do what you want at the planning stage can save a lot of money and disappointment down the line. During the course you will learn specifically what to look for and how to identify potential compatibility issues at the planning stage, and how to avoid both over and under 'spec' equipment for your needs.
Radar & CCTV
In conjunction with the low speed networks such as NMEA 0183 and NMEA 2000 a marine electronics system would not be complete without the high speed network. Devices such as Radar, Sonar, CCTV and night vision require an Ethernet based network, and the MET 3 course covers how the high speed devices can be networked to be robust and reliable in the harsh marine environment. This is an area where providing scope for expandability, and redundancy can save a lot of time and effort down the line.
CAN Bus Technology
Build a thorough understanding as to how each electronic device is interconnected, from the cables, connectors, voltages, pulses, signals, bits, bytes, binary, hex to how the software displays the information. A detailed study of how each parameter is measured and converted to data - such as wind, depth, speed, oil pressure, engine temp, tank levels, and much more, and how electronics devices from different manufactures organise themselves into a polite conversation.
For Both Professionals & Leisure boaters.
The course is aimed at anyone who wishes to learn everything there is to know about marine electronics. Many or our level 3 learners are hands-on boat owners, skippers, and yacht crew, and more recently MECO courses are used in universities, and technical colleges around the world.
