There are two ways to pin-up the RJ45 connector: T-568A and T-568B, the pin-up type has no effect on the data rate, so choose the one you like best. We use the T-568B.
We need a crimper, an RJ45 connector and a twisted pair, and scissors.
Step 1: Cut the upper sheath at the end of the cable about 2.5 cm from the edge. Next, unwind the twisted wires and take out the excess
Step 2: Clamp the wires between your fingers and line them up. Sort them out as shown in the pictures above
Step 3: Shorten the wires so that the wires peek out about 1.5 cm from the edge of the insulation. Use scissors to make a straight cut across all the wires.
Step 4: Carefully insert all 8 wires into the RJ45 connector as far as possible, and make sure they stay aligned and each color goes into the appropriate channel
Step 5: Insert the wires all the way into the RJ45 connector, checking the wire sequence. Then insert the connector into the “P8” socket in the crimper and crimp the connector until you hear it click into place
