TP Cable Termination for Ethernet Communication

It is vital that your Ethernet cable be the correct cable type and that it be properly terminated with the correct
pinout. Ethernet links use Category (CAT) 3, 5e, or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of 328 feet (100 meters).
The cable can be terminated as either a patch cable or a crossover cable (see figure 10) and must be properly
terminated for the application:
•
Patch (straight-through) cable — Connection of the device to an Ethernet hub, router, or switch that also
hosts a controlling computer.
•
Crossover cable — Direct connection between the processor and a controlling computer
