It costs less than $100, so unless your time is completely worthless, you are wasting your time, not to mention that your transponder installation would be totally illegal if you used homemade parts like that in your installation.
I see, but you misunderstood me. I'm looking only for programming cable and software for Becker. I'd like to program factory made address key for Becker so no home made part will participate in flight.
It's no problem but in Poland it's expensive. You have to buy cable for 100EUR, it's about 400-500zł and I'm sure that this cable is normal TTL converter...
Strange politic to make "magic address plug". In Garmin GTX for ex. you can re-program xpdr by special sequence of buttons.
What is there to "program" in a transponder? Surely you are not trying to change it's signals or behavior? Or are you just setting parameters, like the aircraft type?

pwood66889: In mode-s transponder you have to set (program) transponder ICAO code assigned to aeroplane, type of aeroplane, speed range, weight and several items.
If you'll buy used mode-s and install in your aeroplane ATC will see you with wrong callsign.
In for eg. garmin you can just set it in service menu for free. In becker you need special cable and software (why? ) .
So you are just changing internal settings, not behavior. I'm just an old code cutter and curious.
The special cable is probably a lock-in, so you'll keep paying Becker. And provide work for the instrument shops when one installs a used mode-S transponder!
About the only thing I can come up with, Mac, is to see if the plug to the Becker can be sourced any where in Eastern Europe, and get the pin-outs off the `Net. And the communication protocols and so on. Really sad you can't get it COTS. Wish you lots of luck

"Is this kind of thing something the local avionics shop could do?"
I suspect not, Jay. They are probably just board swappers, with maybe a little light souldering on the side. When it comes to bit shuffling, you'll need a lot of stuff that Becker has in their back pocket.
Starting with that cable and the pin definitions. Please do tell us what you find. "Curious Minds," and all that.

A kit from Becker is needed to program the address module on theBXP6403-1-(01) I just bought. There is a Becker dealer in Dallas nearby who quoted it as $233.35, comes with instructions, software on a disk and a USB cord. The upside to this is that the Mode S unit itself can be moved from one airplane to another with only the purchase of another address module (less than $100) that is specific to each airplane and remains in the airplane.
My O-470 powered BD-4 will be up and inspected soon so I then will get to start building my next one so the $$ saved on not buying another xpndr can go for other goodies, or so I will try to convince my better half.
