Technical Support / Re: Becker bxp6401 and adsb out
« Last Post by exfirepro on October 24, 2019, 05:01:30 pm »
Hi Guys,

Looking at the two diagrams, it appears to me that the GPS source is connected to the same pins on P9, whether you are using a serial or a parallel altimeter encoder with your transponder. If I am correct, I would expect it to work using the FTDI USB to serial RS232 converter cable connected as per Chris’s earlier thread which I linked to above - even with a parallel altitude encoder connected to P9.

Caveat - I’m not at home at present, just looking at this on my iPad without the benefit of the full Becker manuals and my knowledge here is limited. If in any doubt I would advise checking with Becker’s technical people first. Transponders are very expensive to repair if you damage them!

Please keep us informed on progress.

Best Regards

Peter

n.b. edited to correct connector reference from J8 to P9

Ok, a quick look shows the Becker Blind encoder connects to connector J8, not J9. Will need to look up the Ameri King.
I assume mode C altitude did work before?

Will look later. Bit difficult on phone.

My blind encoder connected to the Becker bxp6401 is an ak 350 ameri king I tried to upload the schematic but file to big from my phone in the Becker manual 03 issue 05 page 40

Pete, you are not confused, as I have it arse about face.  :-[

I don’t have the Becker manual to hand and will need to look it up before I understand. What is the encoder model?

According to Becker schematic I just connect the 232 to pins 8 and 9 in the p9 connector

@IanMelville,

I’m confused  ???

The data to the Transponder goes from the PAW USB to serial RS232 via the converter, not the other way round. So does Mathew need to convert USB to parallel - and is this even possible? Sorry Mathew, this isn’t something I’ve ever looked into before, so guess I’d need to read up on it. Unless someone else on here can help.

Regards

Peter

If the output from your encoder is parallel only then, you will need to convert parallel to serial before sending it to the USB lead.

I’ve seen the posts thanks my transponder is new this year serial number good and software good I think the ones that have posted are using a serial encoder looking at the wiring pin outs they are saying to use I’m using a parallel encoder I will contact Becker tomorrow when there technical is back in thanks
