Hello joku;

At the very least, make the effort of pinpointing the 3 comm links for which you would like technical info; we don't want to do all your homework for you...

Look up Ethernet, Modbus, Modem, radio etc. Come back with evidence that you have done some research and you will get some sensible answers.

Thanfully, you unlike others have joined the forum. Congratulations.
