If the setup was successful, you will be able to see temperature values on the right-hand side of the RI screen, after the restart.
Learn more about how to:
- Customize your RI user preferences
- Use Gas control and Replay assist
When using Replay assist, do not use any other temperature controlling software in parallel. Any gas changes from a concurrent client, may disable Replay assist for the remainder of the roast.
If the 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?
- Is the correct serial port within the RI selected?
- On MacOS: try installing the beta VCP driver. MacOS X10.15 to MacOS 11 (this is a Beta driver release and the installer should be run from the /Applications folder on your machine)
For further assistance, please create a support ticket by clicking the Support button in the left lower corner of the app. A Cropster support rep will get in touch with you.
