EFIS-D100 Installation Guide - Dynon Avionics

Appendix
Wiring Instructions.
Once you have physically mounted the OAT probe, route its
attached cable to the EDC-D10A remote magnetic compass
module. Your OAT comes with pins crimped on the 3 wires.
Insert these 3 wires’ pins to the following pin numbers on the D9
which plugs into the EDC-D10A. The front of the female
connector is pictured at right. You will be inserting the pins into
the back of this connector.
Pin 2: Yellow wire
Pin 7: Red wire
Pin 8: Blue wire
The exposed shield wires are not strictly required, but may help OAT performance in noisy
environments. If you wish to connect the shield to ground, you may splice it into the blue wire or
connect it to the EDC-D10A chassis.
You may lengthen or shorten the connections between the OAT and EDC-D10A. Use the
provided crimp connectors on the new wire leads.
Do not make connections while the EFIS-D100 is powered!
OAT/TAS/DA DISPLAY
You must set up the EFIS-D100 to
recognize the OAT. The EFIS-D100
supports two different types of OATs as
well as a manual input of the outside
temperature. To set this up, enter the
menu system by pressing any button
beneath an EFIS page, and press MORE
> SETUP > MORE > OAT. Push the
INSTALLED button (either button 1 or

2) to toggle between N, 1 and 2. All OATs sold by Dynon since 2005 are P/N 100433-001, so
you most likely need to select sensor type 2.
Note: Set the OAT INSTALLED parameter to N when you either: a) do not have an OAT at all
or b) have an OAT connected to EMS D37 connector. If you do not have an OAT in the system
at all, the OAT info item will be surrounded by a box denoting that its value can be adjusted
manually.
To display the data from the OAT probe, press any button below an EFIS page to bring up the
EFIS menu and press MORE > INFO. Select the side of the screen that you wish to display
TAS/DA information on (LEFT or RIGHT). Push the button labeled OAT. The values for
outside air temperature, density altitude and true airspeed will be shown.
