Transducer Installation
should find a 1kΩ resistor (color bands: brown, black, black, brown, brown; connect in either
direction) in the package. Connect one end of this resistor to the +5V Excitation Circuit (pin 18)
and the other end to the GP input you’ve connected the sensor to. If you received a sensor with
black/white wires (Dynon P/N 100468), there will be no resistor in the package and you do not
need to make any additional connections.
Be sure to configure the FlightDEK-D180 to recognize the carburetor temperature sensor on the
general-purpose input you’ve chosen as described in the General Purpose Inputs section on page
6-16.
FUEL LEVEL (RESISTIVE) SENSORS
You may connect up to two resistive fuel level sensors to the GP inputs. Generally, this should
only be done if the plane has more than two tanks and the dedicated fuel level inputs are already
used. Connect the output of the fuel level sensor to the desired GP input. Also, connect this same
node to a 200Ω resistor (color bands: Red, black, black, black, brown; connect in either
direction); the other end of which should be attached to the +5V Excitation Circuit. (Resistor
values between 150Ω and 300Ω can be used if 200Ω is not readily available.)
Be sure to configure the firmware to recognize the fuel level sensor on the general-purpose
input(s) you’ve chosen as described in the General Purpose Inputs section on page 6-16.
ROTAX CHT SENSORS
Crimp bare ¼” female Faston terminals
(6.3x0.8 according to DIN 46247) onto the
ends of the wires connected to GP 1 (pin 4)
and GP 2 (pin 22) on the FlightDEK-D180.
Locate the left-side CHT sensor screwed into
the bottom side cylinder head 2; slide the Faston
connected to GP1 input onto it. Locate the left-side
CHT sensor screwed into the bottom side cylinder head
3; slide the Faston connected to GP2 input onto it.

You will find two 1.21kΩ resistors (color bands: brown,
red, brown, brown, brown; connect in either direction)
in the accessories package (Dynon P/N 100446-000)
included with the FlightDEK-D180. Connect either end
of one of the resistors to the +5V Excitation Circuit (pin
18) and the other end to the wire connecting the left
CHT sensor to pin 4. Repeat this with the right CHT sensor.
