SD-Link Bluetooth adapter for f.u.n.k.e ATR833
f.u.n.k.e ATR833 Bluetooth adapter - with the SD-Link-solutions allow you to seamlessly connect your radio to your navigation app, compatible with SkyDemon, Sky-Map, VFRnav, EasyVFR and XCSoarWhether standard, angled, dual-source or pigtail: we'll show you which variant suits your cockpit.

SD-ATR833-E
Plug-and-play adapter between the radio and the D-Sub connector – without additional cabling or mechanical work. Set standby/active frequencies directly from the app via BLE.
SD-Link ATR833-E
Bluetooth adapter (BLE) for f.u.n.k.e ATR833 VHF radios — transmit frequencies SkyDemon and Sky-Map Directly to the radio. Plug & Play, operates via the data interface (12–24 V). For experimental use only.
Add to CartSD-ATR833-A (Angled)
For tight installation spaces behind the panel. Identical functions as SD-ATR833-E, but in angled Design – optionally UP or DOWN.
SD-Link ATR833-A (Angled)
Angled Bluetooth Low Energy (BLE) adapter for f.u.n.k.e ATR833 VHF radios — for installations with limited space behind the radio. Transmits frequencies from SkyDemon and Sky-MapPlug & Play, 12–24 V. For experimental use only.
Choose OptionSD-ATR833-DS (Dual Source)
For cockpits with an existing EFIS connection to the radio (e.g. Garmin G3X, Dynon, Nesis).
Navigation app & EFIS in parallel use – simply plug in the adapter – done.
SD-Link ATR833-DS
Bluetooth adapter (BLE, Dual Source) for f.u.n.k.e ATR833 VHF radios — transmit frequencies SkyDemon and Sky-Map, even with existing EFIS. Plug & Play, 12–28 V. For experimental use only.
Add to CartSD-Link Universal Dual Source
The SD-Link Universal The adapter is extremely compact. Bluetooth to RS232 adapter (BLE 5.0) for f.u.n.k.e Wiring harnesses and runs in parallel to an existing EFIS thanks to dual-source technology.
Direct plug-and-play solution for f.u.n.k.e Wiring harnesses 9-pin remote socketThe pin assignment corresponds exactly to the remote connector of the models. ATR833S, ATR833-II and ATR833A-II.
SD-Link Universal Dual Source
Universal-Bluetooth adapter (BLE 5.0, Dual Source, Bluetooth-to-RS232) for supported RS-232 devices — transmits frequencies from SkyDemon and Sky-MapEven with an existing EFIS. Compact fixed installation, 5–28 V, some technical skill required. For experimental use only.
Choose OptionPigTail PT-GENERIC-BSK833-1
Some ATR833-Wiring harnesses have a 9-pin remote socket instead of a 9-pin socket 5-pin Binder socket. So that these installations also meet the SD-Link Universal (DS) can be used, the PigTail PT-GENERIC-BSK833-1 is available as a perfectly fitting adapter solution.
- Adapter function: connects a 5-pin Binder socket to the SD-Link Universal
- Compatible wiring harnesses (Binder 5-pin): BSKS833S, BSKS833D, BSKS833OE, BSKS833GLS, BSKS833GLD
- Plug and Play: pre-assembled; secure fixation with Conec Latch & Binder Lock
PigTail SD-GENERIC for f.u.n.k.e-Wiring harness with Binder socket
Connection solution to connect an SD-GENERIC adapter to a f.u.n.k.e Wiring harness with 5-pin Binder connector. Plug & Play. For experimental use only.

Frequently asked questions
Devices supported from SW 5.8First supported serial number: 40131610 (Production year 2010).
Older versions (≤ 5.7) are not compatible and may require a software update from the manufacturer.
Tip: The last two digits of the serial number indicate the year of production.
Both adapters are technically identical and can be used plug-and-play.
The Angled variant is designed for installations with limited space behind the radio and is angled either upwards (UP) or downwards (DOWN).
Note: The connector orientation varies depending on the radio model – please check the orientation before ordering.
Dual-source technology can you Navigation app & EFIS in parallel use.
Existing EFIS data lines (e.g. Garmin G3X, Dynon, Nesis) remain intact – the adapter is simply plugged in between.
This way you also benefit from the frequency transmission from your navigation app without losing your existing avionics wiring.
If your ATR833-wiring harness 5-pin Binder socket instead of a 9-pin remote socket.
In this case, the PigTail is placed between the wiring harness and SD-Link Universal Adapter plugged.
This means that the plug-and-play function is retained even with older wiring harness variants.
