  • Have you downloaded the driver for the USB serial converter?
  • Is the correct serial port within the RI selected?

Driver for the USB serial converter

Please reach out to, and attach the following information in relevance to the USB serial converter used:

  • Brand, and model

  • Serial number

  • Picture of the serial converter

A Cropster representative will assess the information, and assist in providing the required driver for the USB serial converter used.
