Hello,



I’m experiencing a MC2 VREF error high 6.60v show up on a MD4 display unfortunately the product is not currently here to troubleshoot but I would like to know if this may or may not be an already known Bug with master to master communication/hardware monitoring. In the MC2 I am not using the module diagnostics for VREF, however assuming it still reports that information to the headmaster.



This is on a 12v system and the only place the 5 volts is used is 7 switches (on/off) as a checksum/and direction change sense to high impedance analog inputs. I have done this before without issue however it was 2.6 software, this is the first one with 3.0 software.



I thought seeing as I can’t troubleshoot it at the moment I would ask and possibly save time if this already a known issue.
