What is needed to configure the EMU-1

← Back

The Actisense Toolkit configures the EMU-1 – please see the Toolkit Manual for further details of how to use this software.

To change the default settings in the EMU-1 to match your installation the Actisense NGT-1 Or an NGX-1 is required.  It would be advantageous to leave the NGT/NGX-1 on-board as it is a great NMEA 2000 diagnostic tool when working with our freely available software NMEA Reader.  As your NMEA 2000/SeaTalkNG network grows, being able to see what messages and devices are on your network will become vital to help you understand any issues.

The Actisense NGT/NGX-1 is a very versatile PC Interface that works with a wide range of Windows software.  Please look at the software compatibility page for a list of the software that can be used.

NGT/NGX-1’s use a baud rate of 115200, which is ideal for use on an NMEA 2000 network with a peak bus load below 50%. NMEA Reader displays the current “NMEA 2000 Bus Load” to help the user understand if the peak bus load is above 50%, and if so allow the user to change the NGT/NGX-1 baud rate to 230400 baud rate.
