 Transducer Installation 
FlightDEK-D180. These fusible links are a simple and cost-effective way to protect against 
short-circuits. 
Next, crimp the two supplied #8 ring terminals onto the wires using the fusing method chosen 
above. Connect the other ends of the fuses to the Amps High and Amps Low leads (pins 24 and 
25) on the 37 pin harness. Unscrew the two smaller screws on the ammeter shunt. Slide the ring 
terminals onto them and screw them back into the base. Connect the “Amps High” lead to the 
side of the shunt marked by “H” in the diagram above; connect the “Amps Low” lead to the side 
marked by “L”. 
If you find that the current reading on the FlightDEK-D180 is the opposite polarity of what you 
want, swap the two signal inputs (Amps High and Amps Low) to obtain the desired result. 
  It is extremely important that you secure all loose wires and ensure that exposed 
terminals cannot touch or short out to other objects in the plane. All metal on the shunt is 
at the same voltage as – and carries the same risks as – the positive terminal on the 
battery. Improperly installing the ammeter shunt can result in high current flow, electrical 
system failure, or fire. 
If you are using GRT’s Hall effect amps transducer (P/N CS-01), route its output to pin 24, the 
Amps High input, on the 37-pin EMS connector. 
General Purpose Inputs 
Dynon Avionics supports many sensors for which the 
FlightDEK-D180 does not have dedicated inputs. The 
instrument has 3 GP (general-purpose) inputs which 
can be used for a variety of sources.

OUTSIDE AIR TEMPERATURE SENSOR 
Note that this section only applies to the OAT with 2 
wires (both colored black/white), for 
connection to the EMS DB37 connector. If 
you have the 3-wire OAT, see Dynon EFIS 
OAT Probe Installation and Usage on page 9-
7. Alternatively, you may still use the 3-wire 
OAT on the EMS DB37 connector by ignoring 
the red wire and connecting the yellow and 
blue wires (irrespective of polarity)
 in the 
same way as the black/white wires described 
here.

Mount Location 
It is important that the OAT probe be mounted somewhere on the skin of the aircraft where it 
will not be affected by heat sources (sun, engine, aircraft interior, etc). The ideal location would 
receive no heat from the aircraft engine or any other source in the aircraft body. While this may 
be impractical, it is a good idea to mount the probe as far away from heat sources as possible. On
