Hi All.
Ok, so I have taken the plunge and I have bought a Rosetta. All configured and working correctly. I wish to connect the Rosetta to my trig TT21.
I have ordered the FTDI USB lead to allow me to make the connection between the two devices.
I appear to have 2 spare USB ports on the Rosetta but only 3off show in the configuration page.
So, which port do I actually plug the lead into and and which port does that refer to on the configuration page to allow to me alter the settings?
Sorry if this is a stupid question.

On Mine it’s plugged into port one, you have to configure it to 9600 Baud in the set up menu,
it works really well,

Hi P1LTS,
On the Rosetta, I recommend connecting the data transfer cable to the lower left USB port (i.e. the one in the centre with the Ethernet port to the left). This allows the cable to come straight out through the existing cutout in the case. If using the recommended FTDI cable the strain relief should slip neatly into place in the hole, though you will have to open out the opening in the case lid to allow it to close.
This port is ‘Port 2’ on the Configure Screen and should be configured to ‘Transponder Trig’ and 9600 Baud. Don’t forget to ‘Save’ the settings.
I’m a bit concerned that you say your Configure Screen only lists 3 x USB ports. Can you post a screenshot please.
Come back if you aren’t sure of the correct settings for your Trig.
Regards
Peter

Definitely only 3off USB ports showing on home screen.(http://)

Those are three USB devices connected. If you click on the "Configure" button at the top of the screen you'll see the setup screen with the four ports listed.

Hi Paul.
What I don't understand is that, they are only 2off USB devices connected and 2off USB ports are free , so why do 3off show on the home page.
Also, is there any way that you can tell which port the info on the home page refers too?
-
Hi P1LTS,
Thanks for posting the screenshot. It confirms what I hoped you meant in your earlier post - that there were only 3 USB devices on the Home Screen. The Configure Screen should list 4 x USB Ports.
The 3rd ‘device’ listed in the Home Screen is the Linux USB Ccontroller (part of the Raspberry Pi setup). There is no ‘easy’ way to link the list on the Home Screen to the actual ports except by recognising the devices themselves. FYI the GPS is the one which doesn’t have any cable attached, and will be in Port 3 to keep its inbuilt antenna (the square bit you can see) in the clear up at the top of the unit. Frankly, being able to tell which device on the Home Screen is in which port generally doesn’t matter, except in the case of specialist kit like the USB/RS232 cable which requires the port to be programmed to suit. The rest should normally be left on their default ‘Auto’ settings.
With the Ethernet port on the left hand side, the USB ports themselves are numbered....
Ethernet. Port 1 Port 3
Port 2. Port 4
Hence the one in the ‘middle’ of the bottom row is ‘Port 2’.

Peter

Thanks Peter.
That’s all very clear.
You mentioned about some help with the configuration of the TT21. What exactly is required?
Again, any help gratefully received.

Hi P1LTS,
I take it you know you connect the Orange ‘Data Out’ wire from the FTDI to pin 5 on the Trig 25-way connector and the Black ‘Ground’ wire to Trig pin 4.
Once all setup, go into configure on the Trig and set GPS Input to NMEA-0831 and GPS Certification Level to ‘Uncertified’. Set 1090 Receiver Installed and UAT Receiver Installed to ‘NO’ - (PilotAware doesn’t count). The other Trig settings are self explanatory. Return the Trig to its normal settings by pressing ENT until it resets.
You should now be ‘good to go’. You can check that your TT21 is getting the correct data for Mode S-ES by pressing the FN button on the Trig control head twice - your GPS position should appear on the control screen. Your own aircraft should also appear at the top of the PilotAware Traffic Screen together with the ADSB Data fields. If this doesn’t happen, try to check it from a separate PilotAware as we have had a couple of reports of ‘own ship’ not appearing on the user’s own PAW Traffic Screen, though mine still works fine.
Let us know how you get on.
Regards
Peter

Thanks for that.
It will be next weekend before I get chance to have a play.
Thanks again.

Afternoon P1LTS
I was wondering how comes you have a very recent version of the kernel 4.14.37-v7+ as per your screenshot above.
I believe the latest version available in software 20180520 is 4.9.35-v7+.
Did you do an update yourself on this??

Alan,
My PAW is also running Kernel 4.14.37-v7, but only because I’m running a fresh ‘full install’ of development software. PAW ‘updates’ are just that - updates. They only update the PilotAware part via USB (.pgp), or Ethernet. They don’t update the Raspberry Pi Kernel.
To update your kernel, you need to download the latest ‘Full Version’ of PilotAware from www.pilotaware.lode.co.uk and do a fresh ‘Full Install’ onto a newly formatted/re-formatted microSD card - which includes reinserting your licence key and all your other Configuration settings. See detailed instructions on www.pilotaware.com

I think this was using a kernel to support 3B+ but we found other issues on the 3B+, and so decided to downgrade to the version used in 20180520
Thx

Hi Peter
Yes I done this just under two weeks ago, a full format and install :(

Hi Lee
Could you please send me a link for this software, it looks like many new owners of the Rosetta will be running this kernel.
I have a friend who bought one a couple of weeks ago, i'll see what kernel he is running too.

Hello...my comments are a little different than your question. The FTDI Friend is a changed out FTDI FT232RL chip connector. Of course, similar to the notable FTDI link, it can give capacity to your task and there are 4 sign lines for sending information to and fro. Be that as it may, the Friend can do considerably more! For instance, you can change the sign and electrical cables to be either 3.3V or 5V.

Hi LS,
Thanks for the info, but for our purposes we try to keep things as simple and straightforward as possible for our users, hence why we recommend the standard FTDI USB to RS232 Serial lead.
Whilst other methods and devices can work, we know by considerable experience that the recommended FTDI cable does exactly what we need it to do to supply position data to a transponder to generate ADSB Out, or to integrate RS232 data from FLARM units into PilotAware without any extra hassle or complication. We also know that it always works, reliably, without the need for any additional configuration, so let’s just Keep It Simple.
Regards
Peter
