Troubleshooting

If Roasting Intelligence indicates No source connected and/or you cannot see any measurements, please check the following: 

  • Is the roast machine connected to the computer? 
  • Have you downloaded the driver for the USB serial converter?
  • Is the correct Serial port selected?

If you have selected a serial port from the Roasting Intelligence, and you receive Sources connected from the bottom-right corner of the roasting application, but you can't see live temperature readouts, you may not have selected the serial port referring to the roast machine's connection.

 

Driver for the USB serial converter

If you cannot select the correct serial port within Roasting Intelligence's Serial port field, your computer may not have the appropriate driver needed to recognize the serial converter's physical connection.

Please reach out to support.cropster.com, and attach the following information relevant to the USB serial converter used:

  • Brand and model
  • Serial number
  • Picture of the serial converter
  • Roasting Intelligence log files

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


Congratulations! You have successfully set up the Cropster Roasting Intelligence.

Your opinion matters. If you have further questions, feedback, or concerns, please submit a support ticket directly from support.cropster.com.
