[amsat-bb] Yaesu Rotor G5400B

Picked up a like new Yaesu G5400B Az/El rotor and controller tonight from a friend. I'm thrilled to add to the station, but need some advice on how to best interface this rotor for computer control working with SATPC32.

Any quirks, tricks, or other issues I should be aware of before installing? It's going inside the attic, so weatherproofing is a non-issue. As always, grateful for the advice. The satellite community is one of the most generous with sharing information, and as a newcomer I'm thankful.
