GPS With GX Devices

We have an installation on an Itama 75 the main components are an 8KW Quattro, and a Cerbo GX. The Cerbo is connected to the NMEA2000 system and displays tanks etc perfectly, it also displays the vessels position speed etc and also works perfectly. The GPS is a Raymarine Raystar 150 GPS as well as inbuilt GPS in all three Axiom screens.

Our test boat also has a Cerbo GX, a Multiplus and links to the NMEA2000 system and whilst tanks etc are all displayed well the GPS position is not available on the VRM portal. In terms of GPS the only difference is that the position currently comes from the Axioms built in GPS.

Can any one help explain this? The GPS function on the VRM portal is excellent when it works, the vessel in question is now in Egyt and is working fine, we are also monitoring a wheel chair built be Mercedes AMG F1 (to whihc we have fitted Victron Lithium batteries, and we need to track a Golden Globe vessel which we are fitting out with Victron equipment so reliable GPS fnctionality on the VRM portal is important.

Best way to setup alarm for low battery and feed GPS location into VRM?

Hi there,

I am using a Cerbo GX, MutiPlus, BMV-712 and SmartSolar charger combination and was wondering what the best method would be to setup those two things:

- Create an alarm, that notifies me, when the battery runs low (e.g. we have 200Ah, receive a notification when like 70Ah are reached)

- Is it possible to feed the GPS position into the VRM from a different source somehow? We have a separate GPS solution already in place and I want to avoid installing the USB GPS dongle for the Cerbo

Thank you,

Geofence - GPS / no GPS notifications


Does anyone know the parameters for information update to VRM?

I have a new instillation on my boat.

(3x 315w panels / MPPT 100 |50 / BMV 712 smart / Color GX / 2x 300ah Relion LifePo4 )

Geofence looks very useful to me to know where the boat is or if it has moved.

I was trying different USB GPS modules and unplugged one that was working and fell asleep before I received notification of no GPS signal. When I plugged in a new GPS it was only a matter of minutes to come back online.

It would be interesting to know how the geofence parameters are set

Venus GX GPS Sampling rate

I'm using the Venus GX device in my Expedition mobile. A GPS antenna is connected via USB to the device. Everything is working fine. Is it possible to change the sampling rate from 60sec to a higher rate like 1sec? For tracking use this would be much better and accurate. As well the export function to KML is just an export including Lat, Lon, Alt, but no speed. The general *csv export shows all other channels but the csv has to get modified to convert it to a proper track file. As well the speed is set to km/h, but the exportis m/s.

Does anybody know what to do, or wether it is possible?

Venus GX - GPS Speed Units


I have changed the units used for GPS speed to mph from m/s using Remote Console. It still shows as m/s when viewing from the VRM dashboard and the ModbusTCP states that the units are m/s in the spreadsheet. Does this unit change not transmit through to VRM and ModbusTCP?

CANVU doesn't see USB GPS


I have tried three different usb GPS devices and none of them is identified.

The root of the problem that there is no tty device created.

Did anyone manage to connect any GPS that works under canvu?

I have tested these:

P: Vendor=1546 ProdID=01a8 Rev=03.01

P: Vendor=1546 ProdID=01a7 Rev=01.00
