Aha - The BioStore / Non-Bio relates to who is the source of data to Impact, ID Manager or something else. You are running a BioStore 1 link (another wrinkle )which is why you are using the non-BioStore link software. Your data flow would be
MIS -> Our Link (ImpactSIMSProcessor) -> Impact -> Bio
A BioStore 2 link is driven by ID Manager, so the flow would be
MIS -> MIS Link (GroupCall or our own) -> ID Manager -> BioStoreUpdate -> Impact
We try and fit in with however the site wants to work, which is why we can have quite a few variations . Hope this helps, any more questions let me know.
Cheers
