Hi guys!
As this feature now have been improved in the later versions I was wondered how this can be accomplished when using the Raspberry Pi. As far as I understand this is supported in devices with VE.Can port together with the VE.Can -> NMEA2000 cable. Is there any easy way to configure this port on the Raspeberry? Can the ethernet port be used for this purpose?
Hi @kurtinge,
you'll need a CAN interface for that, either as a HAT or as a CAN-USB interface. Google is your good friend in looking up all the different devices. They are too many to be listed here.
Together with Venus OS large (incl. Signal K and Node-RED) they are more or less plug'n play.
The PI's ethernet port cannot be used for that.
In my understanding I guess the easiest way is to buy a CAN-USB to RJ45 together with Venus OS large with Signal K and Node-RED. Just plug the ethernet into the LAN where the MFD is hocked up?
I am correct?
I'm sorry, but I'm not sure what exactly you're trying to achieve.
Why do you want a CAN-USB to RJ45? The CAN-USB interface usually comes with a data cable or you need to make one yourself. One end goes to the Data-H and Data-L pins from your CAN-USB interface, the other end goes to a Micro-C M12 (or STNG in case you have a Raymarine STNG network) male or female connector, wires connecting to Data-L and Data-H pins, and will then connect directly to your N2K network. No RJ45 involved unless you need something specific.
Not without extra devices, like a NMEA 2000 to Ethernet gateway. Such a gateway connects to your N2K backbone and your boat's LAN.
Yacht Devices or Digital Yacht and ShipModul have such modules on offer.
kurtinge,
have a look at this wiki:
https://github.com/victronenergy/venus/wiki/RaspberryPi-CAN-Interfaces
has all the supported hats and a couple of usb solutions.
Then you install kwindrem excellent set of tools SetupHelper, GuiMods, VeCanSetup and you're done.
I'm using Waveshare (the cheapest hat I could find) as well as PEAK CAN usb.
Waveshare do a dual CAN HAT as well if you plan to expand with BMS etc.

Hi,
I’m also trying to get my GX device on the NMEA2000 network.
I tried installing a TouCAN Marine (by Rusoku) CAN-to-USB adapter but it did not work “plug ‘n play” on my Raspberry Pi 3b+ running Venus OS 3.50~13
I contacted the developers and they suggested building a new Venus OS (Large?) image with the suggested drivers, then running a command to operate the CAN interface at the 250kbits rate necessary for NMEA2000.
Has anybody else successfully linked a TouCAN to the Venus system? Is Signal K going to be necessary?
I recompiled 3.50 version with TouCAN kernel driver support."can0" interface appears now.

The problem is that it seems that all eth, wifi, bluetooth interfaces are disabled. How to enable them through the console?
I got "A security profile has not been selected..." when trying to connect via an ethernet.

Yes.
I added TouCAN ipk driver to Rusoku web download page.
For RaspberryPi4:
https://www.rusoku.com/storage/app/media/drivers/Linux/kernel-module-toucan-5.10.110-rpi-venus-4_5.10.110-rpi-venus-4-r0_raspberrypi4.ipk.tar
Done.
For Raspberrypi2 and Raspberrypi3:
https://www.rusoku.com/storage/app/media/drivers/Linux/kernel-module-toucan-5.10.110-rpi-venus-4_5.10.110-rpi-venus-4-r0_raspberrypi2.ipk.tar
I prepared the kernel module Venus OS ipk package for a Rusoku TouCAN can bus module.
https://www.rusoku.com/downloads/kernel-module-toucan-5.10.110-rpi-venus-4_5.10.110-rpi-venus-4-r0_raspberrypi4.ipk
Kernel driver source code:
https://github.com/rusoku/TouCAN-SocketCAN
Tested with Raspberrypi4 B and Venus OS v3.41, v4.50
SignalK finds the kernel driver and can0 interface and can work with it.
Installation from a console:
A can0 interface should appear.
