The Dynon D100 EFIS was waiting for me when I got home tonight so I went to town on Bench testing it. Like a kid at Christmas I just had to see it in aciton. The screen was better then expected. The resolution is fantastic. In about 2 minutes I had familiarized myself with the functionality. Since I had done the same thing with the D10A, this was a snap. Not much different other than size. SIZE DOES MATTER! So that's what they meen... I couldn't remember if the EMS firmware version alowed the EMS to display the EFIS information so I hooked up DSAB A and B to the appropriate ends on the EFIS Harness. No worky! So I built a NULL modem cable (Installation manual says this is how to do it for now) which is a cross over serial cable. It crosses 2-3 and contects 5-5 on each end, thats all it is. Plugged it in to the Serial ends and it worked as advertized. When the #6 button on the EMS is pushed it swapped the Engine moitor to the EFIS. It's just a Slave display for most (Not all) of the EFIS information. As I was messing around with the display screens I did find something that was unusual. The EFIS showed "Remote Compass not detected" at the top of the screen. This was fine since it wasn't installed. What I found unusual was that the EMS (In EFIS mode) was showing a HDG indication at the top where it should be. It even followed the movement of the EFIS when I turned it in my hand. I remembered that the D10A had a remote compass but I wasn't sure about the D100. If it has one, then why would it only show on the EMS display. Made a call to Dynon (Ron) and he was stumped by this. After he talked to his Engineers he called me back and told me that there indeed was a Software Bug and this should not be happening. It will be fixed in the next Firmware release. The people at Dynon are Great to work with.

Puch button 6 on the EMS and up it came. Notice the HDG indicator at the top of the screen on the EMS.
Back to the Engine monitor. This is going to be nice in the Panel.
