14.3. NMEA 2000 Configuration
Setting Default Description
CAN-bus Profile VE.Can Defines the type & baudrate of the CAN-bus network. To use in combination
with NMEA 2000, make sure to choose one of the profiles that include
VE.Can and is at 250kbit/s
NMEA2000-out Off Enables and disables the NMEA2000-out function
Unique identity number selector 1 Selects the block of numbers to use for the NAME Unique Identity Numbers
in the PGN 60928 NAME field. For the GX device itself, and when
NMEA2000-out is enabled, also for the virtual-devices. Change it only when
installing multiple GX devices in the same VE.Can network. There are no
other reasons to change this number. For more details regarding the Unique
Identity Number, read the last section in this chapter.
Check unique id numbers Searches for other devices that use the same unique number. When the
search is completed, it will respond with either an OK, or the text :
There is another device connected with this unique number, please select
another one.
Note that there is normally no reason to use this function: the GX device
automatically and continuously checks uniqueness of the numbers in use
and will warn in case there is a conflict. This setting is made available to
quickly confirm that everything is OK after changing the setting.
14.4. Configuration of multiple tank level measurements via NMEA2000-out for
Raymarine MFDs
Modern Raymarine Axiom MFDs are capable of displaying up to 16 tank levels and smaller MFDs such as the i70 or i70s can
display up to 5 tanks.
The following restrictions apply:
1. Currently, the Axiom can only display Fuel (default), Fresh Water, Waste Water aka Grey Water, Live Well, Black Water and
Gasoline fluid types. The other fluid types such as LNG, LPG, Hydraulic oil and Diesel are not displayed. This is a Raymarine
limitation, which may change with a future firmware update.
However, it is possible to configure a specific tank sender's fluid type in the GX device menu to one of the supported ones,
and then rename the tank in the Axiom tank settings (Boat Details > Configure Tanks > Tank Settings) to whatever you like,
e.g. LPG, which is then displayed as LPG tank on the dashboard.
2. The i70 and i70s will display up to 5 tanks where the fluid type must be Fuel. All other fluid types are not displayed.
3. For instancing requirements, see the Instancing requirements when using Raymarine [76] section further below.
4. All tank senders as mentioned in the chapter Connecting Victron products [8] and Connecting supported non-Victron
products [13] are supported.
Configuration step-by-step
Before proceeding with the following steps, you must connect the GX device to the NMEA 2000 network to which the MFD is
connected. Use our VE.Can to NMEA 2000 micro-C male cable to connect the GX device to the NMEA 2000 network and ensure
NMEA2000-out of the VE.Can port is enabled in the GX device.
The procedure below does not replace the Raymarine manual; Be sure to read the Raymarine documentation that accompanies
your Raymarine MFD. Visit the Raymarine Manuals and Documents website for the latest version
