1747-SN & 20-Comm-R

Is a 1747-SN Series B, Rev A, FRM 1.0b compatible with a 20-COMM-R, series A, firmware v1.007 Powerflex 70 adapter?

I remember reading somewhere that you need to keep the series versions the same, but I'm not sure.

I think those should work fine together.

The 1747-SN Series B is the important part; the original Series A's didn't support Block Transfers, and the 20-COMM-R almost always uses Block Transfers.
