Connecting A Trig TT2x Transponder With FlightView

Pre-Made Harness
The TT2x transponder connects to FlightView using a FlightLink USB-to-RS485 adapter. That adapter connects the two TMAP lines (A & B) to the TMAP inputs on the Trig harness via the DB-9 connector that would ordinarily be used for the control head.


If you purchased the pre-made TT2x harness, it comes with the FlightView TT22 cable which is terminated in a DB-9. Simply plug that DB9 into the controller connector on the harness and connect the USB port to your FlightView system’s USB hub.

DIY Harness
If you opt to build your own harness rather than using the pre-built Trig harness, you will need to order a bare-wire FlightView TT22 connector. Connect the TMAP A […]

New Name, Same Guy, Same Stuff

Back in January of 2016 I launched Open Flight Solutions with a Kickstarter to fund the development of FlightBox, a kit for building a Stratux-based ADS-B receiver. At that point I was living in the Kansas City area, and I incorporated in Missouri. Since that time I’ve moved twice – first to California and later to Texas. I’ve also expanded the focus from a single kit product to a growing line of full featured avionics components. Throughout that journey I kept the original Missouri LLC (which was actually Ex Astris, LLC – with Open Flight as a DBA).

When I moved to Texas this past spring, I found out that it is much easier and less expensive to have a Texas-registered company, rather than an out-of-state registration. In an effort to simplify my life and save on administrative costs, I registered “Falken Avionics, LLC” as […]

FlightView Update – 11/23/20

I’m pleased to announce the release of v0.4 release 11 of the app and v2.2r0 of the firmware – a significant milestone on the way to 1.0. This update includes a large number fixes and a number of new features. However, it is very important to note the following:


That means everyone who has a FlightView system out there – installed or not – will need to do the update. The process is pretty easy and I have detailed instructions. Jump down to the section cleverly entitled Updating To v2.2r0 for details.

Changes And Enhancements


The system now includes a database of 500,000 […]

Firmware Hot-Fix 2.1r1 for FlightView

I’ve put together a “hot-fix” update that includes a number of fixes and a few small features. As a hot-fix, this update will need to be installed manually (rather than from the FlightView app). As none of the fixes are critical, feel free to skip this unless you need one of the two new features. These include:

  • Trig transponder configuration – required only if you have a Trig TT21 or TT22 transponder connected to your FlightView system.
  • Gear deploy reminder – posts an audio and display alert reminding the pilot to verify gear deployment.

You can download the hot-fix here. You will need to install it manually. The process is fairly simple:

  1. Power on your FlightView system (or at least your FlightBox Pro EXP).
  2. Connect to your FlightBox’s Wifi network (starts with “FlightBox-“) from your computer*.
  3. Open your web browser and direct it to – the IP address for […]

Alive And Well In Austin

Just a quick note to let everyone know that the move is complete and we are now located at Breakaway Airpark in Cedar Park, a suburb of Austin Texas. Our new address is:

Falken Avionics
2901 Kenai Drive
Cedar Park, TX 78613

Production has resumed on the FlightBox and FlightView lines. We’re currently running about 10 days on a FlightView Core Kit or FlightBox Pro. FlightBox portables are expected to be back in stock the week of June 15. Apologies for the delay. It seems that there has been a bit of a run on Raspberry Pi computers as a result of the pandemic.

Falken Avionics Moving To Austin, Texas

So if you’ve been following this blog for the past several years you might recall that we moved from Liberty, Missouri (a suburb of Kansas City) to Cupertino, California in 2018. That move was the result of a fantastic career opportunity for my wife Amy. Well, two years later she has been offered a promotion with a relocation to Austin. There are few things worse than moving, but in this case I’m looking forward to it. The Bay Area is beautiful, and the weather is fantastic, and it’s so absurdly expensive that growing a small “bootstrap” (i.e. self-funded) business is a significant challenge. The move to Texas will reduce costs (like my $630 / month T-hangar) and make it much easier to grow.

The down-side to the move is that it will disrupt things for a couple of weeks while everything is in transit. Orders for FlightView systems, FlightBox Pro systems and […]
