How to display battery voltage from two BMV-700s on Raymarine Axiom 7?

I have two BMV-700s hooked up via VE.direct to a Cerbo GX. I have the Cerbo GX integrated with a Raymarine Axiom 7 via the network port AND VE.can. I can access both BMV-700s via the Victron App on the Axiom. I can get only one of the BMV-700s to populate the Battery 1 data box on the Axiom. I can't get either BMV-700 to populate the Battery 2 data box on the Axiom. I read the instructions and can change the data instance of each BMV-700, but I can't change the instance to 1. I can change the instance to 2,3,9, or 0, but I can't change it to 1. I used Actisence NMEA Reader and a NGT-1 to change data instances. All equipment and software has been updated to the latest rev.

@merkemarine, I have managed to get this working. I am remote from my boat at present so cant check. This thread I kicked off when I had problems might help.

I left the main shunt (24v system) as data instance 0 and 1. The additional shunt (12v system) I set to data instance 2 and 3. This is the inverse of what I put in the thread, as I reverted it to this model so that any other VE.Can based devices (Solar charge controllers) worked correctly as my system is 24v based and expects the data instance to be 0.

Hope you get it sorted...

Thanks for the response. My problem is the Axiom wants instance 0 for Battery 1 and instance 1 for Battery 2.
