Hallo Greg,
Yes, we did exactly the same and followed the instructions from "A73501860 Issue B" on page 5.
We have now checked several times that this is really the case.
Unfortunately, the system does not behave as described :-(

Danke Heinz

For RS-485, you also need to pull pin 6 low.  Caveat: I haven't tried this yet, but I did have this in my notes as part of the next project.
