Customers are saying

Customers have good things to say about the USB to serial functionality, compatibility with various operating systems and devices, and the ease of use of this adapter cable. Many appreciate its quality and durable construction. However, some customers point out that the cable length is short, and that the lack of included drivers may pose a challenge for some users. Overall, the positive feedback on functionality and ease of use outweighs the concerns about cable length and driver support.

    Stick to true R2-232 card, not emulation

    While this could work in minor COM port applications, i was using it with a device that expects native RS232 voltages. This emulator cable did not provide identical emulation, and so data transmission was intermittent.

    Using to convert serial data from a sensor (eg, weighing scale) into USB format to feed it to Microsoft Excel. The device produced giberish. Several hours with the equipment and software engineers for my system confirmed that this device was not performing.

      Hi.

      I'm really sorry that this device causes such a mess on your data. We sincerely hope that this situation was corrected with a easygoing exchange directly at the store and that everything got to work as expected.

    I give it one star because it will not work with Windows 10 and the box says PC but does mention Windows 7 or older. I found this out after contacting Insignia while looking for the driver online.

    This device will not work for pushing a display from a laptop to a monitor. It requires the same type adapter but with different capabilities so i had to return this item and get a different adapter. It would be helpful if the specs for this item were more specific.

    The cord was returned due to wrong prong configuration. The local store is the worst! Even during pandemic, limited hours if they’re even open and still enforces 14 day return policy! Buyer beware!

    It works but too expensive. This Insignia™ NS-PU99501 cable allows you to connect a device with an RS-232 (DB9) serial port to a USB hub or USB-equipped PC or Mac and supports data transfer rates of more than 115 Kbps for rapid performance.

    This was my second USB to serial cable that failed. Reason I know it is bad is because I replaced it with a different brand and that one works good. Have had several people tell me that they wont use this brand.
