It is not uncommon to see the abbreviation Rx/Tx when looking at network card configuration in ifconfig or embedded development.
Or you can see these two characters on large printers and many network devices.
RX==receive (Downlink) RX==receive (Downlink) TX==Transmit, in which case a packet is transmitted from being switched on to the present, it is Uplink.
It’s also pretty straightforward. R is the beginning of the word receive and T is the beginning of the word Transmit.
This is for the device you are currently on, and the corresponding device is the other way around.
