Well, I have Lady Heather (mostly) working with the OSA-4530. It will probably work with all the 453x units, but not handle all of their commands. The code needs some cleanup and I need to rework the handling of the satellite position and visibility messages (whoever thought spreading out the satellite info across multiple messages was a good idea needs to be spanked). Also, I'm getting occasional com timeouts.
The main issue of talking to these devices is they don't like to handle manually typed character-by-character commands. You need to store the command string in a buffer and sent it out as a unit.
I haven't yet fixed the first unit I received. It has a hard power-ground short on the 5V rail. No obvious faulty parts. The 5V (isolated) DC-DC seems to be good.
