    DB9/RJ-45 Review

    Pros: Once I figured out the pin configuration between ethernet and DB9, these adapters were easy to use.

    I have a 32-port serial hub that has ethernet connections on the front of the hub. I needed DB9/RJ-45 adapters to connect bluetooth wireless serial port adapters to this hub using ethernet cables. These DB9/RJ-45 adapters are just what I needed. I control my tv, blu-ray player and dvd players with my laptop using bluetooth wireless. I recommend these adapters.

    Better off buying one preassembled.

    I rechecked all of the wires, none of them were broken and all of them are in the correct holes. Tried connecting to a router and a switch with both a straight though and a crossover cable. Product still doesn't work. I will find another product that has been tested before delivery. My CCNA exam is next week and I don't have time to play return and retry.

    Cons: You have to put it together your self.

    I was happy when I found the wiring diagram linked to this item. I inserted the pins in order. One of the wires must have pinched/broke when I was pressing the parts together. Doesn't work. Back to getting up every time I need to change the console cable between devices.

    Pros: works, standard parts

    Cons: no wiring diagram with product or on website.

    The adapter and price (less than 1/10th of C2G) are excellent! Unfortunately I had to use my time to meter the pins to determine the pinout. found that the colors match C2G pinouts. here is what I found on mine
    RJPIN color
    1 blue
    2 orange
    3 black
    4 red
    5 black
    6 yellow
    7 brown
    8 white
