Can one just get a BNC to USB cable adapter and connect it to the output of the EVM? If so, what software would be required to view the data?

    Hi Lauren,

    Thanks for reaching out.

    ISOW7741 is a simple digital isolator which isolates logic signals and doesn't involve any software or intelligence. To read USB interface from a PC and convert to SPI, you would require a USB to SPI converter tool. I am not familiar with any such tools but a quick internet search shows many such tools available. You might want to ask customer to use one of such tools to convert the USB signals to SPI and then SPI signals can be passed through the digital channels of ISOW7741 to achieve isolation.

    Let me know if you have any further questions, thanks.
