[TowerTalk] Alfa spid and Green Heron controller

[Gary Smith]

I just connected the Alfa spid I have up 
in the shack, today. All in it seems to 
work fine. The instructions do have the CW 
& CCW terminals reversed and it definitely 
is turning properly.

On this page are the links to the manuals 
for the different models, perhaps the 
older and newer connect differently.

ocumentation.php

Appendix A.8 is for the SPID and has it 
listed as to what is proper.  At the upper 
part of the manual they have the jumpers 
located, you might try looking at those & 
be sure your controller is set up for the 
right rotor.
