EFIS SERIAL HARNESS 
On the EFIS 25-pin wiring harness 
available from Dynon, there are three 
wires bundled together, terminating in a 
standard DB9-pin female connector. This 
cable is 6’ long and pre-assembled for 
connection to a PC-based laptop. Route 
this cable to a convenient location that can 
be accessed whenever you need to update 
your product’s firmware or checklists. 
If you did not purchase a harness from 
Dynon, obtain a 9-pin D-sub connector and make the three connections shown in the table. 
To verify proper communication between the FlightDEK-D180 and the PC, use the Dynon 
Avionics Product Support Program’s “Detect Firmware Version” function. Download the latest 
version of the Support Program from the Dynon Web Site at downloads.dynonavionics.com. 
EMS SERIAL HARNESS 
On the EMS 37-pin wiring harness available 
from Dynon, there are three wires bundled 
together, colored orange, yellow, and black, and 
terminating in a standard D-sub 9-pin female 
connector. If you did not purchase a harness 
from Dynon, obtain a 9-pin D-sub connector 
and make the three connections shown in the 
table.
