Is there some standard how the RX and TX cable pairs in a device are connected to a RJ45 ethernet jack?
Clearly I cannot just connect the TX pair of device A with the TX pair of device B. That would only work with a cross cable.
If a ordinary network cable is used, there must be some place where the meaning of RX and TX is swapped. Where is that usually done? Inside the network hub or in the device?
In my case, I'm working on a measurement device that I want to give ethernet access. It should connect to an ethernet hub just like any PC would be connected.
So, should I swap RX and TX pairs inside my device or is that done within the hub?
