We are often asked what the current SkyDemon Bluetooth “GENERIC” adapter thought is.
After receiving a lot of feedback, we realized that the name “GENERIC” was not the best choice. Therefore, we decided to rename the adapter to SD-Link Universal Bluetooth-to-RS232 Adapter for SkyDemon to rename.
The new name better describes what the adapter can do: a universal solution for various applications – flexible, compact and reliable.

Comparison of the SD-Link Universal Bluetooth-to-RS232 Adapter
The SD-UNIVERSAL-E is comparable in functionality to the IRXON BT578 (or derivatives) – but with a more compact design and an extended operating voltage range.

You can use the adapter for all supported SkyDemon radios and autopilots – with manual wiring.
Attention: For the Becker AR620X is the adapter not suitable!
For this purpose we have developed the specially SD-AR620X-E.
The best for last:
The Pin assignment of the SD-UNIVERSAL-E corresponds to that Remote connector of the funke ATR833S, ATR833-II and ATR833A-II.
Even the old ATR833 with +12 V on the remote connector works.
This means: Plug-and-Play-Solution for these devices!
The remote connector is available in the following Funke wiring harnesses include:
- BSKS833S-S
- BSKS833D-S
- BSKS833OE-S
- BSKS833GLS-S
- BSKS833GLD-S
