Hello AVRfreaks, hello native English speakers,
first I must excuse me, because my question has nothing to do with AVR (though an AVR is used with my application).
But because I know here are very wise guys (maybe also wise girls), I put this question at this place:
On a label I want to tell the user that he/she can do an online service by connecting the signals RxD, TxD and GND.
So, what do I have to write on the label for the connector:
For RS232 service use only RxD, TxD and GND on connector XY. or
For RS232 service use only RxD, TxD and GND at connector XY.
Thank you very much for an answer. In the Internet I found both, but I'm wondering if both is correct...
