SD-Link Bluetooth adapter for funke ATR833

Funke ATR833 Bluetooth adapter – with the SD-Link solutions you can seamlessly connect your radio with SkyDemon, Sky-Map, VFRnav or XCSoar.
Whether standard, angled, dual-source or pigtail: we show you which variant suits your cockpit.

Important: ATR833-S, ATR833-A, ATR833-II-OLED are supported from software SW 5.8.
Older versions (≤ 5.7) are not compatible. First supported serial number: 40131610 (2010)
Tip:: The last two digits of the serial number = year of production.

The standard solution: 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.

Space-saving angled: SD-ATR833-A (Angled)

For tight installation spaces behind the panel. Identical functions as SD-ATR833-E, but in angled Design – optional UP or  DOWN.

For EFIS integration: SD-ATR833-DS (Dual Source)

For cockpits with existing EFIS connection to the radio (e.g. Garmin G3X, Dynon, Nesis). 
SkyDemon & EFIS parallel use – simply plug in the adapter – done.

For the wiring harness: SD-Link Universal (E / DS)

The SD-Link Universal Adapter is an extremely compact Bluetooth to RS232 adapter (BLE 5.0) for wireless wiring harnesses.
In the dual-source (DS) variant, it can also be operated in parallel with an existing EFIS.

He offers one direct plug-and-play solution for funke cable harnesses with 9-pin remote socket:
The pin assignment corresponds exactly to the remote connector of the models ATR833S, ATR833-II and ATR833A-II.

Special case binder socket: PigTail PT-GENERIC-BSK833-1

Some ATR833 wiring harnesses have a 9-pin remote socket instead of a 5-pin Binder socket. So that these installations also meet the SD-Link Universal (E/DS) can use, there is the PigTail PT-GENERIC-BSK833-1 as a tailor-made adapter solution.

• Adapter function: connects 5-pin Binder socket with 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

FAQ

• How do I know if my ATR833 is compatible?

  Devices supported from SW 5.8.
  
  First 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.

• SD-ATR833-E or SD-ATR833-A (Angled)?

  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 (see overview table in the product gallery).

• What are the benefits of “Dual Source” (DS)?

  Dual-source technology You can SkyDemon & EFIS parallel use.
  
  Existing EFIS data cables (e.g. Garmin G3X, Dynon, Nesis) remain intact – the adapter is simply plugged in between.
  
  This allows you to benefit from SkyDemon integration without losing your existing avionics cabling.

• When do I need the PigTail PT-GENERIC-BSK833-1?

  If your ATR833 wiring harness has a 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.

• Which apps are the adapters compatible with?

  All SD-Link TRIG adapters are tested and compatible with the following navigation apps:
  
  - SkyDemon
  - Sky Map
  - VFRnav
  - XCSoar
  
  💡 Tip: In SkyDemon for TY91/TY92 select the device type “Garmin GTR225 Compatible”.

• Do you also support other radio devices?

  Yes, in addition to the funke ATR833 there are SD-Link adapters for other devices:
  
  - uAvionix AV-30
  - Becker AR620X (NG version)
  - TQ KRT2 (also angled)
  - TRIG TY91/92
  
  In addition, the SD-Link Universal Adapter for hobbyists and special setups.
  
  Note: Becker AR6201 is not supported.

• Note

  Our adapters are experimental prototypes and intended exclusively for use under test conditions.
