Troubleshooting

If RI 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, according to the manufacturing year of the machine?
  • Is the correct serial port within the RI selected?

If you have selected a serial port from the RI, 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.


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