Good morning.
First of all, thank you very much for your response.
Sure enough, the FS2 disconnects immediately after connecting. In addition, when I am actually connected, the AsiAir does not control the mount. If I'm in "preview" mode and I want to move the mount with the arrows, nothing happens.
As for the connection, I have a cable that I plug into USB on the AsiAir and which has a male RS232 port on the FS2 side.
As you requested, I am attaching a diagram representing the RS 232 port of the FS2.
Thank you again for your help.
