Using this Ethernet RJ45 Male Connector Terminal Block is a breeze. First, if you want to connect an RJ45 cable to a board with an Ethernet Jack, grab this adapter. You don't need to do any soldering. Just get a thin screwdriver, open up the terminal blocks, then slide your stranded or solid - core wire into the slots. After that, re - tighten the blocks. Remember, this product is great for basic power and data distribution, but it's not the best choice for long - term actual Ethernet traffic. As for maintenance, keep it in a dry place to prevent rusting of the screw terminal block. Also, make sure to check the connections from time to time to ensure they are tight and working properly.
