Here’s what they look like when I am on shore power. The Actisense NMEA Reader displays what the two MultiPlus devices are and shows that one is utility/shore, and the other is the output. The data being sent out for the MultiPlus is a bit different. This was the primary info I wanted so that when I was elsewhere on the boat I could see the state of the house bank at a glance.

I now have battery voltage, battery current, state of charge and time remaining for my house bank, battery voltage for my generator battery all on the NMEA 2000 network. I have two batteries being monitored by my BMV-712 – my house bank is connected to the shunt and is considered battery instance 0 above, and the generator battery is connected to the second monitoring point only for voltage and shows up as instance 1. The other values do not appear to change or have data in them. PGN 127506 – DC Detailed Status includes the state of charge (SOC) and time remaining.

The BMV-712 is sending two useful PGNs – 127508. The Color Control GX shows up as a device but doesn’t send any electrical PGNs as it is just the device facilitating the communication for the other devices. You can see four devices listed above – the MultiPlus is listed twice. These devices provide all of their wealth of data to the Color Control GX, and it now is sending out data to my NMEA 2000 network. I also have several MPPT solar controllers but they aren’t installed yet.

When you install the VE.Can cable, you’ll need to make sure your VE.Can network has a terminator (should have been provided with the GX product you have) and if you have an existing, powered NMEA 2000 network, remove the fuse from the cable so you don’t create a short circuit. You will also need a VE.Can to NMEA 2000 cable, available through Victron resellers for about $95 US. I’m using a Color Control GX for these examples, but it also works for other GX products like the Venus, etc.

You’ll need to be running v2.40 or later of Victron’s GX software – they released v2.41 recently that addressed some initial bugs in the NMEA 2000 support. Enabling NMEA 2000 Victron VE.Can to NMEA 2000 cable However, using these had drawbacks – some features weren’t available unless you used native Victron busses. I had the VE.Direct to NMEA 2000 interface, commonly used between a battery meter or solar charge controller, and I also had the VE.Bus to NMEA 2000 interface, used between an inverter/charger and other devices. There were various other NMEA 2000 interfaces you could get from Victron, but those were specifically for controlling devices, and as a side effect, you got some info from those devices on NMEA 2000. It was nice to be able to see tank levels on their devices, like the Color Control GX, but most people with NMEA 2000 tank level stuff already have ways of displaying that.

In particular, their GX-series of devices has had very limited capabilities – in fact, they have only been able to receive information from the NMEA 2000 network, and only tank information. One of the glaring holes in Victron’s communication has been with NMEA 2000. Earlier this year, I finished the conversion on Rendezvous to a mostly-Victron system which I wrote about in Victron + Wakespeed + Battle Born power system. On my last three boats, I’ve had Victron bits that have helped provide visibility into the power system. It’s no secret that I love Victron’s control ecosystem.
