USB to RS232

s1buell

Does anyone here have any experience with this topic?

 

I`m going from a TUSB2077APTRTUSB2077APTR controller to two FT232RL-REELFT232RL-REEL IC`s just to test this prototype idea.

  • Hi,

     

    I'm not sure those two together will meet your requirement.

    You've posted in the Arduino space, are you looking to attach the Arduino serial pins to a PC via USB?

    If so, then the functionality you need is just a USB-to-UART chip.

     

    If you're looking to attach the Arduino serial pins to a RS232 device, then USB is not required, just a 'RS232 transceiver' chip.

     

    If it is completely unrelated to Arduino and you're looking to create some adapter to connect a PC to a RS232 device then the functionality you need is a USB to UART chip, and a RS232 transceiver chip.

    If you want two RS232 interfaces, a dual UART USB chip can be used (no need for a USB hub chip). and the RS232 transceiver chip(s).

    I have the same doubt of you Shabaz. Then it is not a USB chip but a USB HUB chip, that makes the difference. As far as I know, from the hub you connect USB devices. To at least one piece is missing in the design idea.
