Dynon OAT Installation and Usage Guide

Dynon Avionics

Revised August 30, 2005

Thank you for your purchase of the Dynon Avionics True Airspeed/Density Altitude

OAT probe. The following instructions will give you the information you need to install

and use the probe. Keep in mind that this probe is designed specifically to work with the

EFIS-D10. Do not expect it to work properly with another OAT or TAS/Density Altitude


Tools and Materials Required

• Dynon Avionics OAT probe/cable with nylon nut and washer.

• Drill with 3/8” bit

• Dynon Avionics EDC-D10 remote compass module.

• 2 machined D-sub pins

• D-sub pin crimp tool

• Loctite

Software Required

The Dynon Avionics OAT probe requires you to have EFIS-D10 software version 01.09

(or later) loaded onto your EFIS-D10. Load this version of the software onto your EFIS-

D10 with EDC-D10 connected before you attempt to use your OAT probe. Instructions

for loading new software onto your EFIS-D10 can be found at




Mount Location

It is important that the OAT probe be mounted somewhere on the skin of the airplane

where it will not be affected by heat sources (sun, engine, airplane interior, etc). The

OAT probe must also be mounted at a distance such that you do not have to extend the

supplied cabling to reach the EDC-D10 remote compass module. The ideal location

would receive no heat from the aircraft engine or any other source in the airplane body.

While this may be impractical, it is a good idea to mount the probe as far away from heat

sources as possible.

Mounting Instructions

After the mounting location has been determined, drill a 3/8” hole in the skin at the

desired location. Clip the zip-tie off the coil of cable attached to the OAT probe. String

the nylon washer down the cable and over the threaded end of the OAT probe. From

outside the skin of the airplane, insert the cable first and then the threaded end of the

OAT probe. From within the skin of the airplane, gently pull the cable until the threaded
