    Does this have a RoHs certification ?
    A shopper on Sep 27, 2018
    I'm not sure if this is what I need. I have a connecting cable to connect my cash register to my laptop. But it ends in a female 9pin serial connector - which is what my laptop is too. Do I need this null modem adapter or a "gender changer" to connect the cable to the laptop and have the pin assignments right?
    David B on Jun 12, 2017
    BEST ANSWER: Thank you for your question. Null modem will have a crossover of the 2 and 3 pin where the gender changer will be wired straight. I would recommend reaching out to the manufacturer of your cash register or referencing the user manual regarding the type of connection it will require.

    These are great! After using these it is hard to use the bulky null modem connectors that I have.

    Excellent adapter at a good price
    I use these adapters as part of a receiver control package. They are a very good quality adapter, small in size and I have used many without any problems.

    Perfect for converting a null-modem cable back to a straight-through

    Short ans sweet
    I prefer to us null-modem adaptor female-female but sometimes with cables already in place, it's practical to have such a null-modem adaptor male-male.

    Here is the pinout of it, that I've just probed prior to do this review:
    1 goes to 4
    2 goes to 3
    3 goes to 2
    4 goes to 1 and 6
    5 goes to 5
    6 goes to 4
    7 goes to 8
    8 goes to 7
    9 is not there, on both sides

    Excellent null modem
    These work great, use them for work they are nice and compact and well made.

    Also great that they are male to male, also great on the end of a standard serial cable to make it a null modem cable for programming equipment

    Tiny cable converter
    This simple and small device reverses the necessary pins to convert DB9 into a null modem cable. Does the job as expected and required.

    PROS: Small and solid construction

    CONS: none observed
