I have a Dynon D100 EFIS and use it to send altitude data to my GTX327 Xpndr. The Dynon is configured for Format 4 per Dynon instructions and this normally works fine. However, over the past year there have been 2 or 3 incidents when during flight I notice the Xpndr is displaying dashes instead of the typical altitude being sent it by the EFIS (displaying the altitude is a configuration option of the GTX327). Both times when this has occurred I corrected the situation in flight by entering setup on the Dynon and I then go to the Altitude encoding configuration option. I verify it is set to Format 4, then I set it to Format 3, exit setup mode, then back to setup and set the Format back to 4, exit setup and the altitude then appears on the GTX327 again and all is well. If it happens again I will just try power cycling the EFIS to see if the unit recovers or if I have to mess with the Format configuration again.
Was wondering if anyone else has experienced this problem, if so it may be firmware related otherwise it could be something unique to my EFIS / installation.
