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, according to the manufacturing year of the machine?
-
Is the correct serial port within Roasting Intelligence selected?
If you select a serial port in Roasting Intelligence and the application confirms "Sources connected" but still shows no live temperature readouts, the selected serial port is likely not the one corresponding to the roast machine.
