I do remember that it used to work in the past. but recently I tried to connect asiair plus to ioptron az mount pro and it wont connect. I am using the latest asi air firmware and mount is set to "ioptron az mount pro & nnn handset" with connection set to serial and baudrate set to 115200. The asiair tries to connect and then an error shows up saying failed to operate mount and disconnects.
I have checked the cable. It works fine from a pc using ioptron commander, connects to the mount and slews the mount. The cable also works with stellarmate but I dont like stellarmate, its very slow.
