@mvader (Victron Energy) Hi Matthijs,
I hope you will find few minutes to answer my question.
Is there a plan to implement reading of more NMEA2000 PGNs to be able to better interface Cerbo GX or Venus OS to vessels' electronics?
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 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!
Full system includes 4-25.6V LiFePo4 smart batteries, 3-24V-5000 Quattro in 3phase, VE BUS BMS, CCGX, BlueSolar 150/85 chargers, 2-Skylla iP44 chargers
Other than using bluetooth, (the batteries are too far away in a steel boat to reach via BT) is there a way to access the individual cell data on a network? The CCGX is connected via VEBUS and is on the ships ethernet network. An HTML page similar to the Remote Console page from the CCGX with all the battery data on it would be very useful to have on the ships bridge. Another way might be through NMEA 2000 data broadcast by the CCGX in PGN format and displayed by Maretron N2K View software. Has anyone been able to access battery data other than through bluetooth? I am aware there are BT extenders, but the process of connecting to each battery for one page of data is not useful, having all the data on one page or HTML screen would be what I am after.
Is there a way I can connect both a BMV-712 and a MultiPlus 2000 to NMEA to view from my MFD but without buying a CX device?
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?
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?
Can you get the ET112 to show on NMEA 2000 device list via Cerbo so you can show on glass bridge display ac loads/ shore power without out using a Multiplus or similar in the system.
I'm having a problem with marine instrumentation on my N2K network. The entire network is single manufacturer, and after looking at the network with a multimeter, the Cerbo GX does not seem to be conforming to specification. Specifically, when the N2K network is powered down (Cerbo is still connected to the LiFePo bank, and powered), there is no resistance between the two data lines on the N2K bus. When the Cerbo is removed from the bus, there is the appropriate 60Ω resistance. When the Cerbo is powered down too, ie., BMS is shut down, then the 60Ω resistance is present as well.
The other manufacturer wants to see N2K certification for the Cerbo — does anyone know if this has been passed?
Does anyone know if the N2K adapter cable is trying to power the N2K bus? There is a fuse hacked into the N2K end of the cable, but I'm unsure if the device is trying to draw power or provide it.
Any advice appreciated.
I have a network with a Multiplus conected to a Cerbo, which is connected to an NMEA network. NMEA is turned on.
I'm not seeing the MultiPlus AC data on the network. I have interrogated the network and it appears the Multiplus outputs AC data on PGNs 65013, 65014 and 65016. However, the network requires AC data on PGNs 127503 and 127504, which are teh normal AC Input and Output PGNs.
Has anyone seen this before and know of a resolution?
On a ship, I run a BMV-702 for monitoring state-of-charge, and a CCGX for data logging. Both of these are co-located with the battery bank. Is there no (simple) means to gain access to the state-of-charge information for a remote display of some type? By simple, I mean something like a serial output.
I have found the details surrounding the the CCGX to N2K cable, MFD solution, and references to an earlier cable which connected a BMV to N2K. However, I then need to run an N2K (CanBus) network between the two locations, and a CanBus transceiver at the remote end (and deal with the more complicated protocol). That is all doable, I was just hoping for something simpler...
Hi, we have recently integrated our B&G system with a CerboGX using the NMEA integration cable. We had two existing freshwater tank monitors on CanBus that worked as expected for about 2 years. They have VRM instances 1 and 2 with no notifications. When we integrated a few of the electrical KPIs to the helm chart plotter a weird byproduct arose. The tank sensors are only visible when the chart plotter is powered up. We do not display tank information on the plotter just Volts, Amps, SOC. The speed of the vessel in kts we show on the cerbo touch50 it disappears as well but I guess that is to be expected given its sender is off. Turning on the second chartplotter that does not have this data integrated had no effect. The NMEA-N2K network is always powered on from each of the 2 trunks having their own 12v inputs and generally the boat is always on unless undergoing electrical maintenance. We have updated all components on the network (except the tank sensors, cannot figure that out and they are not Victron) to the latest firmware. TIA for any insight on this.
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
I recently installed the SeeLevel II n2k system and am now connecting the Cerbo GX and Touch 50. One question I have is do I really need to use the 120 ohm resistor I just read about on here? Used the 3m connector everyone recommends and a ethernet cable to the VE.Can port. Seem to have tanks working on there. Didnt use the Rj45 termination plug either. Is that necessary?
Lastly I do not have the tank levels showing up on the main screen on the touch 50. I can access but only thru menu options and not always displayed on the main screen.
.(15) - BMS-Can port is a port dedicated to be used for connecting managed batteries
.Second CAN-bus port (also features BMS-Can (18)) 1.(18) The secondary CAN port,
available on some GX devices as per table above, can be configured
to be used as a BMS-Can port, as well as other profiles
Thus it is suggested that the "BMS-Can" is a "Feature" added to the construct of CAN-bus port. However 1.(14) states "The hardware does not meet the requirements for a VE.Can port; and therefore is BMS-Can only. "
While states "The BMS-Can protocol doesn't use addressing". (I believe protocol should be port).
Furthermore it is inferred the BMS-Can port and CAN-bus port are really running the VE.Can / NMEA2000 Protocol but ignoring the addressing priority built into the protocol (maybe through some hardware omission in hardware or protocol stack).
Question 1. Thus, what is the difference between VE.CAN port, CAN-bus port and BMS-Can port?
Question 2. Some GX devices (Venus GX and Octo GX) have secondary ( non-isolated) CAN-port with active BMS-bus feature. [1.(18)]. Does then mean a second battery can be monitored and managed by the Venus or Octo with the active second port? If so, can the batteries have separate Shuts or system voltages?
