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
system.
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

Installation
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
