    DB9, M/M, Null Modem Mini Type

    RS-232, DB 9 pin male to male null modem.

    Null modems are used to connect two computers or other devices together to achieve file transfer. Null modem connectors are different from straight through connectors because the receive and transmit conductors are crossed.

    This is a miniature null modem with male connectors on each side.

    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.

    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.

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