Thanks Walter - Yup I'm using your USB to serial cable with (per our prior thread) pin 2 removed. The ifly is set to Extended which I think means 9600 baud and the Dynon D10 Efis is simply set on 'Auto-detect'. The Efis is also the autopilot. Everything works great. Weather would just be the icing on the cake.
I have one of these (http://www.ebay.com/itm/280718314894?...) cheap USB hubs that I use on an old PC but I haven't bought anything to use with the ifly yet. Figured I'd try what I have however would be more than happy to get whichever brand you recommend. I liked the idea of the something similar to the one shown since I could velcro it to the back of the Ify which would give three ports pointing back for 'devices' and one on the side to replace the Ify port to use for memory stick updates.
Thanks in advance for your help. Your product and support is amazing.
