    What you need? You have RS232 device and want to connect that device to PC without RS232 port, PC have only USB?

    If yes, you can use provided or similar circuit.



    If PC have RS232 port and you want to make RS232 to USB you need different circuit. Additional to this USB ports can be implemented with installation of PCI-PCIe cards with USB ports.

    In DIY project you can add and implement RS232 to USB support in device itself.
