 Posted: Thu Apr 17, 2008 4:56 am Post subject: Encoder / Transponder question |
 |
|
I'm in the process of connecting up some avionics HW and need some assistance. I have the Ameri-King AK-350 encoder and the Garmin GTX-320A transponder. My question is where do I hook up pin #18 on the Garmin ? Its listed as Altitude D4.
The AK-350 doesn't have an altitude D4 pin and I can't find a reference as to what D4 actually is. Is my AK-350 outdated?
The AK-350 has a DB-15 pin connector and the Garmin has a DB-25 pin connector
Anyone have a schematic laying around that includes the Garmin. My AK-350 is new in the box but about 7 years old.
A google search did not provide any worth while results

I have not searched for the 320A manual I have for the Glastar but I believe you do not need to hook up that wire. I believe that the encoding is binary and the D4 provides an altitude that you encoder does not support; Your encoder may be limited to 20000 but the Garmin may be able to report 30000 to ATC. Additionally Garmin can supply a pdf of their old tech manual.

IIRC the first nine pins provide 8 bit binary to indicate altitude and one bit for sign. This will provide altitudes from -1000 to +25600. The D4 would be the tenth binary digit and provide encoding from -1000 to the +63000 that the 320A is capable. Short story you do not need to hook it anywhere..
