Hello all!

I have a kt76A (Bendix King) Transponder that I am wiring up to a Dynon Avionics Blind Encoder Converter that then goes to an Efis-d100. Anyway I am having trouble with the wire placement on the KT76A I have been to all the sites, including http://www.aeroelectric.com/Installation_Data/ and http://www.aeroelectric.com/Installation_Data/KT76A-76C-78A.pdf to get the wiring guide, the problem is the numbering does not match up! Using their convention the bottom of the fitting would be (right to left) A B C D E F G H I J K L and the top would be (right to left again) 1 2 3 4 5 6 7 8 9 10 11 12 (top works out perfectly) but they say it goes to N (top part) what letters do I skip? OR am I even doing this correctly?

Thanks for you help

Has anyone figured this out yet? I too am wiring a KT76A to a Dynon D-100 and I am using Dynons Encoder Converter.

I don't understand the numbering/lettering on the King plug. On page 7-34 of the Dynon manual it tells me to connect the:

Yellow to A1 (on the King plug)
Green to A2
White/Blue to A4
Blue to B1
Orange to B2
etc...

Which pin is A1? or A2, A4, B1 etc...??

This may be simple but I'm just not getting it!! I can see what pin A could be. Or I can count and find pin 7. But how are they combining them to get something like A4?

Thanks

PM me with your email address and I'll email you the KT76 manual in PDF that I have. There is a drawing in there where King numbers the wires with A1 as they connect to a King encoder, etc and shows how those connect to the actual pins of the KT76 connector. The guys at Dynon must have used the wrong set of identifiers in their diagram.

I figured it out! okay...actually I didn't figure it out but someone told me how they are labeled. Dynon has it correct-I just didn't realize that B1 for example is really pin E.

Thanks!

I am wireing a kt76a to the dynon converter and am having the same problem numbering. Can someone give an example of the Dynon numbers to connect to the KT76A.

I realize this is an older thread but I just joined this forum and I need all the same info. I need a installation and operators manual for a Bendix/King KT76A TSO transponder and I am also installing the Dynon alt. encoder converter to be used with my Dynon EFIS D10A. I need wiring info for all this stuff. Thanks for any help.

What this manual doesn't tell you is the "missing letters" from the connector scheme - the G and I are missing. If you find a KT 76C manual it has a diagram with all of the pins labled.

Mollex connector pin part number 08-03-0304 - Available from Mouser.com - their number 538-08-03-0304 - order extras...

FYI
Pin-out letters G and I are not used in this plug because "G" may be mistaken for a "6" and "I" for a "1".

The lettered pin-outs on this 24 pin plug are: A B C D E F H J K L M N and the numbers are 1 through 12
Hope this helped.
