Andy Johnson converts engine, transmission and electrical system data to NMEA2000 and displays the numbers on his Moody 31 chartplotter.

Veethree EGM (Engine Gateway/monitor)

This unit has been included firstly because it also works with the automotive ‘J1939’ network used on larger engine instrumentation systems, converting the data into NMEA2000 format. Secondly, because it is probably the best-engineered product I have seen in a long time, and for that alone it deserves a mention.

Simply scroll through the pre-configured senders.

Each dial position in the display has different options, and there are several different ‘pages’ for display.

A massive capability is packed into this small unit and, if you read the manual from the beginning, you are guided through both the wiring and set-up details.

Data input sources
J1939-derived data
NMEA2000-derived data
Seven pre-allocated sender signal inputs
One tacho input
One NMEA0183 input – for GPS data

Data output

All the above can be displayed on the EGM itself and converted in format for pushing out onto the NMEA2000 network and displaying elsewhere. Fuel management ‘page’ performs a number of consumption calculations.

Setting up

Set-up is done directly into the EGM and very straightforward. As with the Actisense device there are industry-standard senders pre-configured, and you also have the ability to set your own calibration for new senders which will activate the current source. There are pre-set alarm levels for oil pressure, coolant temperature and fuel level; but again, retain the original engine alarms as well.
