Cerbo 3 x Ve.Can Connections?

I have 3 things I need to connect via Ve.Can:

REC BMS
WakeSpeed WS500
VE.Can to NMEA2000 connection

But 3 Cerbo only has 2 VE.Can ports.

Is there a solution whereby I can connect all 3?

Hi @Jokani,

afaik REC BMS should go to the BMS Can-port and using a different speed rate (500kbit/s vs 250kbit/s). WS500 and VE.Can to NMEA 2000: it should be possible to daisy chain them as the WS500 has two ports.

And a reminder: the VE.Can port of the Cerbo GX is not isolated. So maybe you should think of a bridge device to isolate VE.Can from N2K like with this device: https://www.yachtd.com/products/nmea_bridge.html

Certified NMEA 2000 device ports are always isolated.

WS500 uses a different pin out than the standard VE.Can and VE.Can to NMEA 2000 cable. Make sure you get the pin out right. Should be in the manual of the WS500.

And I found this interesting thread in the WS500 forums, which more or less describes how to wire what you want: https://www.offgridsoftwaresolutions.com/ws500-user-forum/topic/victron-ve-can-and-canbus-to-ws500/

Good luck with that and please let us know how it works.

I just edited my post above with a small note.
