end of the OAT probe pokes through the hole. Thread the nylon nut down the cable and
up to the threaded end of the OAT probe. Spread some loctite around the threads of the
OAT probe. Twist the nut onto the threads of the OAT probe and tighten.
Wiring Instructions.
Once you have physically mounted the OAT
probe, route its attached cable to the EDC-
D10 remote magnetic compass module. Crimp
female pins onto the yellow and red wires, but
leave the blue wire/shield combination bare.
Plug the yellow wire into pin 2 on the female
D9 connector which mates with the EDC-D10.
Plug the red wire into pin 7. Connect the blue
wire/shield combination to the same ground
which feeds the EDC-D10 through pin 1. The
front of the female connector is pictured at right. You will be pushing the pins into the
back of this connector.
WARNING: DO NOT CONNECT WHILE THE EFIS IS
POWERED!
OAT/TAS/DA Display
Once you have uploaded the latest version of software onto your EFIS-D10 and installed
the OAT sensor, you can view data obtained from it. To display the data from the OAT
probe, bring up the menu system and navigate to the INFO menu (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 should display in the format seen below. Temperature is
displayed in degrees Celsius, density altitude in feet, and true airspeed in knots.
Example:
OAT 25C
09960FT
090 KTS
Calibration and Adjustment
With no calibration or adjustment, it is possible for the OAT sensor to read as much as 5
degrees Celsius off the actual value. Therefore, it may be necessary to adjust the
displayed air temperature value to compensate for this. To make this adjustment, you
must enter the menu system and proceed through the following set of button presses:
