Dear All

Need help in understanding the wiring diagram in a simpler way that I can understand. The project is already done by HerrRiebmann and is posted on github however i cant understand his wiring diagram(https://github.com/HerrRiebmann/KDS2Bluetooth).

The Schematic L9637D is the diagram by him. However a simpler explanation in a typical wiring diagram would be helpful.

 

Take a look at datasheet functional description -

Hi,
Dana

can you help interpret in the format I have uploaded (IMG_20180508_144141.jpg)

 

If you look at 9137 datasheet shows a typical wired application.

In short you wire the Tx and Rx pins being assigned on Arduino to the
9637, the buss side on 9637 then gets connected of vehicle ISO9141 buss.
