Becker bxp6401 and adsb out
« on: October 23, 2019, 08:04:56 pm »
I’ve seen some post for connecting paw to the Becker but I think most have used a serial encoder and ground pin 2 in the p9 plug I have a parallel encoder plugged into p9 and pin 2 is a encoder line for me anyone got this working yet with the output results to show it working

Hi Mathew,

Take a look at this thread...

http://forum.pilotaware.com/index.php/topic,1209.msg14234.html#msg14234

Chris (Moffrestorer) managed to do this successfully, though it seems to be subject to how old (in both hardware and firmware terms) your transponder is. There are also several other posts about this on the Forum - you can find the full list by searching ‘Becker’ (without the inverted commas) from the Forum Home Screen. (Searching from anywhere else won’t bring up the full list).

Hope this helps.

Regards

Peter

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

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.

@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

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

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?

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

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.

sorry this is the schematic other one is for a serial encoder attached to j8

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

But the second diagram shows gps connected to p9 and pin 2 on j8 grounded to enable the gps

Hi Matthew,

I think I see your confusion here.

If you are using a parallel encoding altimeter Plug 9 pin 2 isn’t available for “GPS Enable” function as it’s used as a data line. So you must ground Jack 8 pin 2 instead.

In Section 2.6 “Settings after Installation” of the Becker Manual, you must select, through the menu function, the type of Encoding altimeter being used. If you select “Parallel”, which is the default, the data line P9 pin2 is presumably reconfigured away from its use as GPS enable to altimeter data functionality. It would probably be a good idea to confirm this with Becker Support, first!

NB. I used Issue 4 of the manual dated June 2016, I see you have issue 5.

Thx,

Chris

Yes I’m using issue 5 and I’m sure I have to select parallel in the ins on the Becker with the 232 connected to pin 8and 9 if I configure the usb to gps I get failure on the Becker but if I select trig it’s fine but I haven’t been able to test if this is working correctly as I don’t have another spare pilot aware to check while I’m out Flying I am speaking to gerhard from Becker tomorrow so hope he shines more light on this thanks for your input
