G'day Folks, --( yes we really do say that in OZ!!) Our group has just completed an RV7a, first flight last week. We have installed a D120 & D100, they are connected via the DSAB. Everything is going well with the exception that our Garmin 495 is not communicating with the Dynons. The blue data out wire from the GPS is connected to pin 19 on the EMS, -the auxiliary serial receive pin, & the GPS interface is set to NMEA out. We have had the briefest of flashes of a Magenta message saying something like "awaiting data" or a similar message in the top right hand corner of each Dynon unit, but these messages disappeared & have not been seen again.. -- any suggestions will be gratefully received! Cheers, thanks, Dino......
