RS 450 200 no ve.can

Came in the other day and there was no communication between the mppt and the cerbo.

The rs shows up in app on Bluetooth.

Updated to latest firmware.

Plugged ve.direct cable between rs and cerbo and got the 4 screen shots. (Bottom right was when ve.direct was unplugged)

Plugged in rj45 port (both ports on rs, both ve.can ports on cerbo, 3 different cables)

@65nw

Did you put a can terminator in?

no! i did not. it was working but something seems to have changed.

good thinking. so an rj45 cable and a resistor soldered in? I'll look for a recipe.

Your Cerbo had a bag in the box that includes 2 of the correct VE.Can terminators; I'd expect the MPPT RS also included them, but not sure about that.

Found them and came back to say that was the issue.

Thanks and sorry for taking up server space with this.
