AccessXpert V2 configured MR52 Interface with inputs and outputs showing as Not attached (See snapshot)
At one point, the MR52 interface was configured with elevator controls.
Remove the configured elevator references on each input and output individually and resave the point.
Delete and re-add the points and configure the I/O as needed.
V3 works differently then V2. V3 allows for a more granular configuration so that the I/O selection just allows for the specific elevator other I/O selections. In V3 the assignments doesn't need to be released, only reselected.
