Master / Expansion Different -Batt

Kevin 4 weeks ago in Master modules / MC4x updated by Gustav Widén (System support) yesterday at 6:09 a.m. 2

We have a requirement to have multiple XC43 modules remotely to the master MC43FS module. Its likely they will all be powered from separate power supplies and they wont supply the same 0V for batt -ve.

Is this likely to be a problem in terms of interference etc?

Is anyone able to comment on this please?

When connecting CAN bus modules, you want the ground levels to be roughly the same. 

CAN tolerates some voltage potential difference between modules, but if the voltage potential difference is to large you can have problems.
