I was trying to connect my IFly unit to X-Planes 9.70. After getting the iFly serial cable, the serial expansion card with the serial ports, and the gender changer, I was still having difficulty getting the two to talk. I then noticed in the "About" menu on the iFly, there're a limited number of serial port numbers recognized. I looked in my PC hardware manager and noticed I had selected an expansion slot that did not show one of the recognized serial ports on the iFly. I relocated my serial expansion card to a slot that gave me COM7...COM2 and COM3 are not available on my PC for what ever reasons. I went back into the "About" menu and got a little "punchy" with the features of the COM ports. I thought I selected COM7 for "GPS Default" and deactivated the other ports. I then exited the Navigation mode. I fired up X-Planes, plugged the USB serial cable into the iFly, and then started up the Navigation. I'm assuming this is where I went wrong because after 2 hours, I still can not get the iFly Navigation mode to initialize successfully...it remains in the screen where it asks you to "Please Wait." I have tried to restart the unit several times, tried the GPS reset, and I've even tried reloading OS 7.5.20 with no luck. Any ideas/input will be greatly appreciated! Thanks!
