    Nice unit, nice price!
    I was hoping I could use the parallel port on this for an old software license dongle, but it wouldn't see it when I had it mounted. That is not the fault of this unit, but the old software just couldn't see the dongle on my newer computer. The unit installed easily, and drivers were loaded without problems. I had a little confusion when I tried to distinguish which ports were which in Device manager, but finally sorted that out. Unit works well, and the price was great!

    PROS: Easy setup, drivers available both online and on disc. Unit works well. Easy setup.

    Works great, easy to install
    Using an old printer on Win 10 machine without any parallel or serial ports. Plugged this card in, installed driver, works great! No issues at all.

    PROS: Works

    CONS: None

    Excellent add-on card.

    PROS: This replaced, one of another manufacture, that I had purchased about a year earlier. This one worked, no trouble! The earlier one did unpleasant things to my computer: most notably, when turned off, you waited about 30 min before the machine would boot.

    CONS: None

    Works Great Low Cost PCI-E 2 RS-232, 1LPT1
    The base address of your parallel port is changed so do not expect 0x378. You will need to configure any software that uses parallel port to use the assigned address by the Multi I/O Card but this is expected.

    PROS: Low cost as usual from monoprice, PCI-E card, and WORKS! New PCs no longer have serial or parallel ports and if you need to interface with older equipment that requires serial, parallel port and you only have PCI-E slots open in your PC like I did this is the way to go.

    CONS: None
