Description
TRIG TY91/TY92 Bluetooth adapter for SkyDemon, Sky-Map and other navigation apps — SD-TY9X-E.
The SD-TY9X-E is a compact Bluetooth adapter that connects between the TC90 control unit and the Sub-D connector of a TRIG TY91/TY92 VHF transceiver without any additional wiring or mechanical modifications. You can then transmit standby and active frequencies directly from the app via Bluetooth Low Energy (BLE).
The adapter also works when an EFIS (Dynon, G3X etc.) is already connected to the radio — we call this feature Dual Source.
Key Features
- Compatibility: Designed for TRIG TC90 control panels, compatible with TY91 and TY92. Works with TC90 control panel firmware version 1.5 and higher. An existing EFIS (Dynon, G3X, etc.) can still be used.
- Simple installation: The adapter is plugged in between the existing wiring and is held securely to the housing thanks to two Sub-D knurled screws.
- Power supply: No additional power supply required; handles on-board voltages up to 28 V. An integrated fuse provides additional protection.
- Requirements: Works on the 12V bus (TY91) and 24V bus (TY92).
- Compact design: Dimensions 48 × 45 × 17 mm, Weight 50 gr.
Important note: This product is intended for experimental purposes only. Our page " Bluetooth adapters in aircraft: what is allowed?" explains what this means for UL, experimental, and certified aircraft.

Excellent device. Seamless connection to trig Radio, no need for an external power supply or any changes to the existing wiring loom. Just connect it in, power the radio on and configure sky demon and the magic happens!

The installation went very smoothly thanks to the excellent documentation. Connecting it to SkyDemon was very easy and straightforward. The slim design even allowed for easy installation in the very narrow panel of my FK12. I'm thrilled and will definitely recommend your products.

The adapter installation went very smoothly thanks to the excellent documentation. Connecting it to SkyDemon was also very easy and straightforward. The adapter's slim design made installation in the FK 12, which has a very narrow instrument panel, quite feasible. I'm thrilled and will definitely recommend your products.

I ended up using it in a Piper Cub J3 with excellent results. The solution is quite useful in the J3 as the position of the radio is very awkward. For this setup, it would be better if the unit were 2 mm thinner, but this is just a detail. I want to order an additional unit.
