What are the deets on the low serial number F50EX DEECS?

 

A  !non-embedded! Falcon 50EX below serial number ____ has 9 pin DEEC download ports.  Not the same as a F50…Not the same as a 900…not the same as a F50EX with embedded interface.  and no, yo cannot just take the upper cowl off and download directly from the DEEC.

 

A decade ago, Honeywell was able to provide the 9 – pin adapter . for $1800.00 and 6 months lead.  Good luck even getting the part number now.

Here is what we worked out after much trial and tribulation! Thanks Marcus!

 

CAUTION: pin 1 orientation on the RJ12 end is to the left when the tab is held down.  You may have a similar !!!! or !!!! reverse cable end.  WIre to the pin positions, not the colors.

Not for the faint harted, I had probably 100 hours and $600.00 in this by the time it was done.  If you just need a Heater/AC control, this is WAY TOO MUCH trouble for that.  I recommend the many websites that explain how to modify a Accord Heater/AC control panel. I approached it as a learning experience to push my knowledge of the Arduino farther along.

Auto reconnect after keyswitch is turned on.

1.The trick was to send data all the time from the arduino.

2. in AI, test the incoming data field to see if it is empty.

3.DISCONNECT the BT, even though it is already disconnected.

4. reconnect to same connection.

5. I error trapped the screen so that the nuisance errors would not take over the display.

Thanks Marty

The elevator servo is also used in the stall warning system as a stick pusher (Chapter 27-31-00, STALL WARNING).

How does the radar graphics/ EGPWS switching work in Astra N900DL sn030?

 

After it all settled out, the actual problem was a Radar Graphics Adapter that failed with heat:
