I hooked up the VE.Can to NMEA 2000 cable between my Cerbo and my boat's bridged N2K-STNG network - and cross-over devices immediately appeared on both systems - but I'm having trouble configuring them on the Victron side.
I'll start with the incoming (to Victron) tank devices - they immediately showed up on VRM:
And when I look in Devices on the Cerbo, they are there - but I am unable to change the parameters. Fuel (2) above is actually Water - when I try to change the type in the Cerbo UX it doesn't take the change and immediately goes back to the device configuration screen. I am able to change the capacity type to gallons and that persists, but if I try to change the capacity (in this case to 60 gallons) and hit the checkmark...it does NOT persist. I also looked at possibly changing the device IDs of the Cerbo pre-defined tanks but they are read only. This isn't the end of the world but it's bugging me and I'd like to get the configurations correct. How can I change the configuration?
On the Victron N2K outbound...I cannot find a way to get the Devices that the documentation shows. Section 11.3 starts with a UI shot and zero context about how that screen was accessed:
My screen (whether I use the Lynx or CAN-Bus profile) is different - it doesn't have "Devices"
The Cerbo manual points to this blog post, which has the same screen as I have:
....and says "In the coming days we’ll be updating the Marine NMEA 2000 and MFD integration documentation; taking out the now deprecated interfaces as well as adding the earlier released MFD App Integration."
So...reading this now at home...I'm thinking that my UX is "correct" and the Cerbo manual did NOT get updated with the current UX. And that the "Devices" isn't to configure just the devices on that interface, but is a redirection to the Devices submenu on Setup.
My Victron devices are showing up on my Raymarine network - the Cerbo looks reasonable:
But the MultiPlus and the SmartShunt need configuring:
I'll try to get to my boat today to verify, but has anyone been able to configure Victron-based N2K devices successfully?
Cerbo can send NMEA data to Raymarine, but is it possible to display data from Raymarine NMEA2000 network on Cerbo GX and from there further to VRM? Eg. wind, gps or other data.
I am struggling with the following: on my motoryacht I recently replaced a Czone 3.5 inch display with a Czone Touch 5 display. On the 3.5 inch display I can show the AC in and AC out of my Victron Quattro. The Czone display is part of a larger NMEA2000 network with various Czone modules (for digital switching) and several navigation equipment. My Victron GX is connected to the same NMEA2000 network. On the Simrad NSS 7 (and 12) chartplotter I can show the AC in (not the AC out). With software tools from Maretron and Actisense, I can see that the AC in and out information is available on the network and is published by the GX in PGN 65013, 65014 and 65016.
According to a Czone specialist Czone does not support PGN 65013-65016 and the information of AC in and AC out should be published through PGN 127503 and 127504.
It is strange that the Czone 3.5 inch display does show both AC in and AC out and that the Czone Touch 5 does not. Both are from the same brand Czone (by Bep Marine).
This has already cost me more then a week studying all manuals, websites and other available information, but I have not found a solution to show the AC in and AC out on the new display.
Is there a way to transfer or convert the AC in and AC out information from the PGN 65013, 65014 and 65016 to the PGN 127503 and 127504 so that possibly the Touch 5 will display the desired information.
Any help is appreciated!
Hi there, i have just found that Victron outputs Ac status on PGN 65013-65016 , is there a way to get the unit to output 127053 and 127054,
Trying to integrate a full Victron Lithium and power system with Czone,
Two 800ah Victron battery banks with Quattro, VE.Bus.BMS, CCGX control on N2K. We are having an issue setting the device Instance for the CCGX. We contacted Maretron and we are both in agreement that because the CCGX acts as a gate way to the N2K unless we can change the Device instance only one battery bank will show information to the N2K network. We have tried with N2K analyzer and with Actisence Software to change the Device Instance with no avail. When selecting the device instance on network page the number changes but soon as you hit enter it reverts back to 0. We have a large system and maybe this is cause a problem. We have tried several configurations to change the Device Instance but nothing has worked.
I connected my 2 BMV712 as well as my MultiPlus Compact 12/2000 via VE.Can to NMEA 2000 cable to my CERBO GX. I read the instruction on https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-nmea2000.html but I'm still not sure how to configure each device in the VE.CAN setup. Accessing my NMEA network via a WIFI gateway (Yacht devices) and playing around with the instances does not seem to work to get access to each monitor separately.
Initially I had all inputs on instance #0 but the NMEA interface seem to read two inputs at the same port.
Are there any instructions / guidance beside the above where I can read up how to configure the CERBO GX?
I am using an Cerbo GX 2,4V and have an REC BMS connected to the BMS-CAN port and then i have connected an VE-CAN to NMEA2000 cable to the VE-CAN port.
All data from the REC BMS is displayed correctly in the Cerbo, inkluding the SOC.
And Volt, Ampere, Temp is also transmitted correctly in the NMEA2000 network, but the SOC remains 0%. How to make it send SOC correctly? (26% in this case).
I just added on a couple temp senders to the Cerbo unit and have it reporting on VRM. I have other data from the Cerbo reporting on my NMEA 2000 network such as inverter power, battery voltages and such. I have not been able to see the temp sensors on my N2k network. In the cerbo device menu the temp sensor shows it has an instance number assigned of 25 but from my maretron screen there is no temp data available other than known other devices. Any one else been able to get this to work?
Hi, my 8kVA quatrro has very noticeable hum when on mains power. I can not yet find a pattern, but if I isolate mains, no noise add mains in = noise.
It sounds like a torroid or transformer hum, the frequency is stable at 50Hz, the voltage around 253 VAC.
To me the slightly high mains voltage should not make anything hum, any thoughts out there or similar experiences?
I am working with a NMEA2000 Network with multiple GX devices. To each of the GX is one Smart Shunt connected. I am able to read the Data given out from the Shunts on the Network with my Micro-controller (Tiny Tiger 2 from Wilke Technology). My Problem that I can't seam to solve is that I do not receive the same amount of Data or NMEA2000 Packages from each Shunt. Which should be every 1.5 sec resulting in ca. 40 Packages every minute. I do not know if this Problem is due to the Hardware from Victron (Cerbo GX or Smart Shunt) or if it is a problem with my Micro-controller. Maybe someone in this Community could help me.
I would deeply appreciate it.
Can I add datafields from Victron GX to the infobar on right side? I would like to have voltage value and solar PV charger value. Other NMEA2000 equipment can be implemented in the sidebars.
I have an NMEA2000 network with a lot of Maretron items, Cerbo GX with NMEA out, and a REC BMS master-slave setup. The REC Bms is connected to the BMS Can on the Cerbo GX with 500kbps, Ve-can has 2x MPPT smart solar, and Skylla running on 250 kbps. Ve-bus has 2x Quattro in paralell. As soon as I connect the Ve-Can to NMEA cable every device after the Cerbo GX on the NMEA network disappears from the n2kanalyser software( greys out). I have used the original Ve-Can to NMEA cable and have made 2 new ones myself with all the same results. The Victron network on its own works great and the "maretron" network including all the navigation items runs great too. The NMEA network is rather big and consists of 2 networks bridged by an NBE100 from Maretron. Has anybody seen this before?
Seems strange this isn't available on the Victron website (at least as far as I have been able to find), but can someone tell me how long the Victron VE.Can to NMEA 2000 cable is? Is more than one length available?
Thanks in advance.
Are there any plans to add 3rd party n2k temp sensors to Venus OS?
I have a number of Maretron sensors monitoring fridges and freezers that would be fantastic to monitor via VRM to prevent warm beer or worse, defrosted bait!
Operation would be similar to how the tank monitoring works now.
I have the digital input on my venus GX configured to measure water consumption. I now have connected the venus via the VE-Can to N2k and miss the option to monitor the water consumption on my MFD. It would be nice to be able to configure it as water tank. Did I miss something or is this currently not possible ?
I've been lurking here for a while and find the idea of running Venus OS (large) on a Pi an attractive option. However, my reading of the history (and documentation) of this impressive project has left me a little bewildered since there are so many options, some of which may now be obsolete.
I have N2K on my boat and have decided to replace some of my ageing electrical installation (from another dutch company :/ ) with the following: Multiplus II (12/3000), 2 x smartsolar MPPT, Smartshunt. My existing LiFePO4 is already protected by my own design BMS which speaks N2k.
It seems that I need to buy a bunch of Ve.direct to USB adapters and a Ve.Bus adapter. For the N2K, its unclear, I assume an available Pi hat - is data flow bi-directional? Will Venus OS pick up my BMS N2K messages and use them or will it prefer the Smartshunt values? Will the smartshunt values make it to the N2K bus so I can use them in my BMS (for comparison and backup)?
Sorry for the variety of questions :) Looking forward to a positive discussion.
P.S. I'm switching my purchasing decision towards Victron due to the open sourcing of Venus. I'm very grateful and find it very freeing to know that I can integrate whatever I want into my system now rather than being stuck with the straighjacket of closed systems offered by competitors
I'm looking to connect a Maretron TLM100 tank sender to my VenusGX system (3ph Quattro and Lynx Shunt setup).
Can i just buy the "VE.Can to NMEA 2000 micro-c male" adapter and connect it to the TLM100? That would be the only NMEA 2000 device i would use.
I have my VE.Can bus terminated in both ends now, and since there is only one RJ45 connector on the adapter, does it work like a terminator aswell, or how do i terminate the VE.Can bus?
I have 3 Quattros in prallel, does removing the VE.Can bus terminator from the Venus GX have any impact on the Quattros, will they continue to work or will they shutdown?
Hi. I have a BMV-700 monitoring my amptron 100ah lithium battery which is charged from a redarc bcdc1225d with vehicle input whilst the vehicle is running, and solar input usually. For the purposes of testing the accuracy of the SOC I disconnected the solar and haven’t turned the vehicle on. If I run a load such as 6 amps until the SOC on the BMV is around 90% and I then leave it, it slowly trickles up to 100% even though the voltage stays within 0.1 of a volt. I end up with the SOC being 100% but the voltage being 13.25, for example.
My settings on the BMV are:
Battery capacity: 100ah
Charged Voltage: 14.1V
Tail Current: 3%
Charged Detection Time: 5 minutes
Peukert Exponent: 1.05
Charge Efficiency Factor: 98%
Current Threshold: 0.02A
When I recharge the battery I’ve tried synchronising manually but it doesn’t change anything.
I have a fridge which draws approx 4A when the compressor is running, but other than that there is no other load or input into the system at the moment, but the SOC still gradually returns to 100% over the course of a few hours or so.
Any clues as to why the SOC might be slowly trickling back to 100%? Thanks very much.
I currently have a system with a MultiPlus 12/800 with Venus GX, I would like to control the ON and OFF activation of the Multiplus via the CAN bus / NMEA2000 interface of the Venus GX.
I know the CAN bus protocol well but much less the NMEA2000, from what I understood it is possible to activate the MultiPlus via the NMEA2000 standard.
Which frame should I send to activate the MultiPlus?
Thanks for your help.
J'ai actuellement un système avec un MultiPlus 12/800 avec Venus GX, je voudrais commander l'activation ON et OFF du Multiplus via l'interface CAN bus / NMEA2000 du Venus GX.
Je connais bien le protocole CAN bus mais beaucoup moins le NMEA2000, d'après ce que j'ai compris il est possible d'activer le MultiPlus via la norme NMEA2000.
Quelle trame dois-je envoyer pour activer le MultiPlus ?
Merci pour votre aide.
I have a Colour GX connected to NMEA system alongside an Empirbus on a Narrowboat and the water tank level was successfully shown on the colour display using the NMEA CAN adaptor. The water tank sender I believe is the Oceanic System/offshore dynamcis 3281 (Volumetric Tank Sender). This has been working successfully for 4 years and I noticed with recent update this has stopped appearing coinciding with a rewiring job.
I have checked on the Empirbus logs and the tank level sender is transmitting with the FluidLevel PGN and tank sender id. However, the source address is now 255, which seems strange.
Given that there is more NMEA integration with the ColourGX, I am wondering if this has had an impact.
Do you have any suggestions?
I apologize if I missed something already posted, but I’m trying to connect an N2K SeeLevel Tank monitor to a CCGX.
I am a bit confused as to what I physically need to facilitate this connection.
I have no other N2K “network” or system in place, and only have the CCGX and the SeeLevel (N2K enabled) controller head.
Is there a cable I can buy (or pinouts for a cable I can make myself) to connect these devices directly to each other?
There was a reference made by @mvader (Victron Energy)
For clarity, the “Victron N2K adapter to which @ben refers is just a plug converter goes from micro-c n2k style to RJ-45 Victron VE.Can style.
No electrical components or software in there.
Your help is greatly appreciated
I read in the v2.6 release notes that:
the ability to read GPS (location, height, speed) from the N2K network has been added.
I can't get this working with my CCGX running v2.66. It can see the other devices on my n2k network. I unplugged my USB GPS and rebooted.
Any tips on where to look or if there are any configuration options that need to be set? I couldn't find any.
I want to connect my Cerbo GX to the NMEA2000 network using the VE.CAN->NMEA2000 cable (ASS030520200). Would it then be possible to control the relays of the CerboGX via the NMEA2000 network (i.e. via CZone) ?
Would it also be possible to read out the binary-inputs of the Cerbo GX via the NMEA2000 network?
Maybe I am missing something, but I can't seem to be able to output the temperature sensors connected to my Venus GX to NMEA2000.
I can see every other detail from my Victron System on NMEA2000 but not the GX Temperature sensors.
What am I doing wrong?
I have read several posts and the manual but I still can't make sense of how to get the Cerbo data to display on either my Raymarine I70 or Axiom display!
i have the app working through the Raynet cable which is nice but I also have the NMEA cable wired from Cerbo to the Seatalk NG network (NMEA2000).
I am looking to get tanks and battery data out.
I can see everything listed on the under the NMEA listings on the Axiom but can find them when i tr to add to a new page.
I have read several posts on here regarding changing Device instances on the Cerbo or having to telnet into the Cerbo and change the Data instances i find the manual rather ambiguous!
has anyone done it and can give me an idiots guide please?
My Victron setup is 2x Quattro in parallel to VE Bus, 2x smart solar mppt and the Skylla-1 in parallel connected to a Cerbo GX via VE-Can also a REC BMS is connected to VE BMS everything works well. As soon as I connect the VE-can to NMEA 2000 cable the Skylla-i goes into error mode. All the cables have been replaced with the exception of the ve-can to nmea2000 cable. When I remove the VE-Can to Nmea cable the Skylla-i comes back to life. When the Skylla-i is removed from the parallel string the VE-Can to nmea 2000 cable doesn't cause any problems. When the Skylla-i is running stand-alone (just with the control panel ) it works fine also, I also have swopped the ve can ports on the Skylla-i and the Cerbo GX but it makes no difference. I haven't got the fuse installed in the VE-Can to nmea2000 cable as my Maretron network is already powered. I also tested my new spare Cerbo GX same results. Any ideas???
When I try to connect to the Cerbo GX using the Victron app on the Raymarine Axiom MFD I get a connection error "no hardware found" and the application does not start.
The Cerbo GX is connected to the NMEA2000 network using a Victron VE.Can to NMEA2000 cable and the Raymarine Axiom MFD is connected to the same NMEA2000 network. The NMEA2000 network works fine and is properly terminated. Since the Axiom is connected to an Quantum 2 rader with cable the Axiom must connect to the Cerbo GX through the NMEA2000 network.
The NMEA network diagnostic screen on the Axion shows not only the Cerbo GX. But also all the devices connected to the Cerbo GX with VE.CAN, VE.Bus or VE.Direct. Attached is the NMEA2000 network diagnostics from the Axiom listing all the NMEA2000 devices as well as the Victron devices that the Axiom can find on the NMEA2000 network.
- The Raymarine Axiom is running the latest lighthouse operating system (v3.13.103 Edgartown)
- The NMEA2000 network is powered separately and the fuse in the VE.Can to NMEA2000 cable is removed
- The Raymarine Axiom can see the Cerbo GX on the NMEA2000 network (and all devices connected to the Cerbo GX, including tanks)
- The Cerbo GX and all connected Victron devices are all running the latest firmware
- All data from the Cerbo GX are visible on the NMEA2000 netowork and can be displayed in other ways such as webguages with yachtdevices wifi gateway
- On the Cerbo GX: one VE.Can port has a VE.Can terminator and the other VE.Can port is connected to the NMEA2000 network using the VE.Can to NMEA2000 cable
- The NMEA2000 network is a Raymarine SeaTalkNG network
- The VE.Can to NMEA2000 cable is connected to a SeaTalkNG<->NMEA2000 cable that is connected to a "white" device port on a Raymarine 5-way
Cerbo VE.Can port settings:
- CAN-bus profile: VE.Can & Lynx Ion BMS 250 kbit/s,
- NMEA2000-out: Enabled

since I could not find anything about this.
Is it possible to have several GX in one NMEA2000 Network as shown in the Picture ?
Have a VE Direct to NMEA 2000 converter connected to a BMV702 and the NMEA2000 network and I can see the battery voltage and Amps on the NMEA2000 network all is well
Now we have installed a CCGX Fw2.23 and connected the BMV702 via the VE direct port to the CCGX and the correct battery details apear.
Now comes the issue
I then plug the VE direct to NMEA 2000 converter into the CCGX and no data is seen on the NMEA 2000 network
on the CCGX the VE direct to NMEA2000 unit is not seen in the device list
I have tied a secound ve direct to nmea2000 unit just in case I have a faulty one still the same
The targeted result is to see volts and amps on the NMEA 2000 network
has anyone got any suggestions
