This is on version 2.3 / 11.56. Ioptron HAE43 works with ASIAir Plus, but not with ASIAir Pro. Error message on ASIAir Pro is Connect Failed. Please make sure the mount is connected with the serial cable and the baud are correct. Not sure at which release the AA Pro stopped working with the HAE43. Both the Pro and the Plus work with my Ioptron CEM40. Same cabling in both setups, tried with and without usb hub. I reloaded from scratch on the Pro, and then it updated to current release. Still no joy.
I do vaguely recall something about changing the baud rate eons ago, but there seems to be no way to do it now, and why would it work on the Plus, but not the Pro. Any ideas?
