Hello experts,
Just a simple question in front: In case I connect two interface that both have the RxD signal on pin 2 and the TxD signal on pin 3 this to my understanding requires a "crossed" cable. When do you use a "straight" cable? - IMHO this prerequisites a swapped pin assignment on one side. Are there interfaces that work that way?
And the second question: How can I upload a file in this Forum? This would make it easier to explain for what I like to request your help...

Could this signaling work?
