Connect CCGX to SeeLevel N2K tank monitor interface

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)


as follows:

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.

which makes me wonder if I can connect them directly??

Your help is greatly appreciated

Two different Lynx Shunt, one bus, one Cerbo

I have two different battery banks and two Lynx Shunt.

Both are visible with the Cerbo GX with ID 0 and 1, and also seen in VRM

But for the moment only one bank/shunt can be monitored.

How to get the two Lynx Shunt be monitored ?

I also have a VE.Can/NMEA cable and it is unusable. Data from both shunts are seen under Battery Bank 0 by different NMEA displays, instead of Battery Bank 0 and Battery Bank 1.

Any help will be welcome.

CerboGX NMEA 2000 integration and older Raymarine hardware

I am on a Lagoon 2013 catamaran and was wondering if anybody has configured NMEA2000 integration between a Cerbo GX and an older Raymarine system running Lighthouse II (ie., no Glassbridge software)? If so was it worth the cost and effort? #LighthouseII

VE.Can to NMEA 2000 cable bad?

I just bought a new VE.Can to NMEA 2000 cable as I didn't have one on my current boat. I wanted it so I could leverage the CCGX 2.40 feature of sending data out on my NMEA 2000 network.

I've spent the last 45 minutes troubleshooting and can't get it to work. I've installed these several times before, and have a very documented and extensive NMEA 2000 network. I've tried both VE.Can ports on the CCGX, rebooting, power cycling, upgrading to v2.40 via SD card from the beta, moving the VE.Can to NMEA 2000 cable to four different NMEA 2000 ports on my network, and have validated everything else on the network is working correctly.

Either this brand new cable or my CCGX are faulty, or there is another setting I am missing. At the minimum, even without v2.40, the CCGX should be showing tank levels (I have multiple Maretron TLAs for tanks) as it has in the past, but I see nothing.

I've turned on the new CAN-Bus feature including Send Data to VE.Can, but something more basic is not working.

I also have Actisense and Maretron software and can see the devices on the network, and Victron has never shown up in any of the testing.

Is there a pin out diagram for the cable so I can test it, or another way to test the VE.Can ports?

Color Control GX NMEA out via WI-FI?


Have the Victron Color Control GX and it’s working perfectly in standalone mode with Quattro, MPPTs, etc. Firmware version v2.87.

I have connected the GX to the onboard WI-FI network and it is visible and has an IP address assigned by my router.

I have a Windows machine running Signal K server on the WI-FI network and I would like to input NMEA data from the GX into the Signal K server. However, I’m not able to see any NMEA output from the GX IP address on ports 1883 or 8883. I have tried TCP and UDP.

The Signal K server is able to receive NMEA data from B&G MFD and YD WI-FI gateway which are also connected via WI-FI

I have also tried using the NMEARemote app (iOS) to connect to the GX and also have no NMEA data being received. NMEARemote is able to receive B&G and YD NMEA data

Is it possible to receive GX NMEA data via WI-FI? If so, what am I missing?

Thanks in advance,

CCGX crashes the NMEA bus

I have installed a LiFePo4 system in my boat (see diagram). When I insert the VE Can -> N2K cable in the CCGX the whole N2K system is wiped out. It happened before, when I had connected the CCGX after the MultiPlus Remote Panel. Having changed it to the present set up it worked well. That was last season. This season, after having installed Load Disconnect and Charge Disconnect it doesn't work. Any clues? 120097 LiFePo4 inst incl Alt & Gen v10.pdf

Connecting Smartsolar 150/70 ve.can to N2K network kills the network

Hi all!

I have a fully functineing NMEA 2000 network on my boat. I am trying to add a Smartsolar 150/70 using a Victron ve.can-NMEA 2000 cable. The fuse is removed. A soon as i attach the cable to the N2K network i start getting network form error. I get over 200 errors/second. Removing the cable its back to normal.

An Error 20 is a “Form Error” which is….

CAN Form Errors

In CAN, the End of Frame, ACK Delimiter, and CRC Delimiter are all fixed format fields that are always recessive. If a node detects a dominant bit in any of these, a form error will be flagged.

Any suggestions?

Can the VE.direct port on the smart shunt be connected to the NMEA 2K bus via the Ve.direct to N2K cable converter?

A stupid question: the VE.direct port on the smart shunt can be connected to the NMEA 2K bus via the Ve.direct to N2K cable converter?

if not, why?

Unable to connect to Cerbo GX from Raymarine Axiom using the Victron App

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

Raymarine integration in nk2 network with several Victron devices that send battery data.

I have several devices in nk2 networks that send battery data such as Multiplus, MPPT, rec-bms and smart shunnt. Without modifications, only two batteries will appear on Raymarine instruments. (I have 3 battery banks) Based on testing to display battery data correctly on Raymarine, we have used a programmable interface and changed "device instance" and "data instance" to see how data is presented on Raymarine display. Changing the device instance as described in the Victron GX manual chapter 11.5.4 does not change anything on Raymarine instruments! (Tried this from the venus os menu as well) When we change the data instance, the battery is presented correctly. This was also the case on thread eg posted about 1 year ago about data instance. The question is why device instance is made available in menu on Venus os and manual describe that change of data instance is not recommended?

Anyone have experiences to share that can confirm this? Do other manufacturers use device instance for numbering batteries?

Battery SOC data from NMEA

I have battery state of charge, temp, voltage (and lot's of other battery data) available on my N2K network coming from 3rd party sensors. Can I read this data from NMEA via Ve.Can into Cerbo GX and use this data to control Victron equipment (MPPT and Multiplus) attached via the Victron network (VE.Bus / VE.Direct)?

VE.CAN + NMEA 2000 + Fischer Panda Generator

I'm planning on an install with the following VE.Can devcies: Cerbo GX and Lynx Smart BMS. I am also planning on installing a Fischer Panda generator, and would like to use the J1939 connection method so I can log data from the generator as well as do automatic start/stop. Last, but not least I would like to have the Victron data on the N2K network to display on the chartplotter.

What would the best way to accomplish this? Reading the VE.CAN to NMEA2000 documentation, it appears that it would be best to have a VE.CAN to N2K cable for each device, but should I do that with the generator as well?

Alternatively, maybe it would be easier to keep a separate VE.Can network with just Cerbo GX, Lynx Smart Shunt, and FP generator and then install a Raspberry Pi w/ N2K and SignalK and pull the Victron data over MQQT?

VE.Can to NMEA2000 - What data?

I bought a VE.Can to NMEA2000 cable. thinking it would show me lots of data, now I'm not so sure, and as Cerbo GX is limited to 2 Can connections only, I'm tempted to dispense with it.

I currently have a Multiplus and a REC BMS, connected, what data would these provide over NMEA2000 that I can not see already?

Connecting 2 GX Devices, separate systems, 1 x Multiplus & Battery

Reposting from a comment to an older answer by @wkirby as a new question....

Further to your answer, where you say you can connect a 2nd GX device, but not share between the 2 GX's:

I already have a Multiplus with CCGX plus a separate existing extensive N2K network on a boat & want to expand monitoring to include several tanks, wireless temp monitors & share some data from each of the CCGX & Cerbo with the exisiting N2K network.

I am happy to keep the the 2 GX devices as separate systems (but effectively sitting on the same N2K network), and would prefer not to replace the CCGX with Cerbo+Touch 50/70 for the existing "House" Electrical system which has been working well for 3+ years:

Would it be possible to add Cerbo via VE CAN to CCGX and then connect the Cerbo to the N2K network via a single VE Can to NMEA 2000 cable?

Many thanks
