Default Stratux Serial Output for GRT HXr

I downloaded the latest image (ver 1.2 ) which provides a serial output.

Q1: Is the serial output through the GPIO pins or does it require a USB/Serial converter ?

Q2: I have a Keyspan USA-19HS USB/Serial converter that did work with an image provided by a VAF member, it does not work with the latest image.

Do I need a converter with the CP2102 chipset., I dont think the Keyspan has that chipset.

I read that certain software commands may be required to make things work, I thought such commands would be part of the image.


Additional thoughts about USB devices, does it matter which USB ports a device is connected to, what happens if you move the devices around. Is a device logged into the EEPROM and will only work on a specific port until the EEPROM is reset ?

Peter

Just a little bump, surely Vern knows the answer

Peter,

I'll try. I have Stratux on a GRT Sport HS and it works fine.

1. You need a converter using a CP2102 chipset. They are about $10.

You should not need any special commands. However be sure you have the latest HXr software loaded. GRT has some Stratux specific updates.

My understanding is that it doesn't matter what port a device is plugged into. I've switched my devices around and when next powered up it works properly.

Hope this helps.

Thanks Jim, I did download the pi3 zip from GRT, after the download I had two files, the zip file showed 0 Kb and there was a .part file with data, does the .zip self unzip into the .part file ?

Default My thoughts

I have a FlightBox ads-b wired to my Horizon WS and it works great. "Open Source Solutions" who sell the FlightBox (Stratux) also sell a USB to RS-232 conversion kit for $45. I put my FlightBox above the storage area and ran a 12 foot USB cable that I cut off one end to access the orange wire in the cable. The orange wire is the only wire you need to hookup to your HRx.

If you go to the GRT website and download the Stratux Open Source ADS-B Supplement document (http://grtavionics.com/Stratux%20Rev%20D.pdf) it will give you specific instructions on how to connect the Stratux to your GRT equipment. Section 3.1 of that supplement will describe the program changes you need to make to your "General Setup."

Good luck. I love my FlightBox. The FlightBox feeds my iPad through wifi and my WS through the USB setup. The USB setup always comes on line faster than my iPad wifi setup.

Peter,

I am using the image from the original GRT supplement. It is something like v0.8 It requires the USB to TTL conversion dongle etc. I got my Stratux operational back in March 2016 and haven't changed it since.

If you have the CP2101 chip set serial converter, you should be able to use the latest image from Stratux.me. I think it is v1.3b3. With that you should also be able to use 115200 baud.

There have been some changes by GRT. Note that HXr v5.0 has "Add special handling for data from Stratux ADS-B receiver"

Chris Young is putting on several workshops at OSH. I'm hoping to get some upgrade questions answered there!

Sorry I really can't answer your question.

You don't want to use the older Stratux versions if you can avoid it. Many fixes and improvements. I posted the details of my installation on Github and included the amazon links for the parts. I used USB (FTDI chipset) on the GRT side($5 adapter). You will need to make one configuration change to get the CP2101 (the only adapter chipset that the std Stratux build supports) adapter to work. This connects to the Pi via USB. The details are on that post as well.

Good luck,

Larry

Larry, just getting started with a Stratux/GRT setup, and found this thread while looking for info on the subject.

Any chance you could copy the info you mention above onto a post here at VAF??

Or, at least the Amazon parts links?

How are you dealing with the fact the Stratux wants a shut down command from some wifi device instead of simply being connected to a power switch like the rest of the avionics? I really do not want to have to deal with anything other than simply a power switch to turn it on or off.

Try searching for my post on Github. If you can't find it, I will look at my amazon order history. I also will try to find the post and copy it here.

I didn't have any wifi shutdown problems. However, I finally gave up on the stratux a year or so ago. I just had too many problems. I also struggled with tx speed. The planes on the screen lagged well behind what I saw out the window. I replaced it with a Pathfinder ADS-b receiver and it was a big difference. Targets now match reality and no wierd problems and intermittent shut downs.

Mike,

The Stratux serial adapter is not available. You can try contacting Chris directly from the Github page to see if he is getting more.

You can use the one from Open Source Solutions or one from Amazon such as KNACRO CP2102 module. With these you use the latest Stratux software, v1.4r5.

I think you have a GRT Horizon WS. You need to update to the latest software on it too. I think that is WS36.00. If you read the notes, at the bottom one of the last statements is support ADSB receivers.

Let me know if you need help.
