Golden Roasters (with touchscreen) - Roasting Intelligence (RI) Setup (Alpha)
This manual covers the connection of a Golden Coffee Roasters (Nazar Kahve) roast machine with touchscreen to Cropster's Roasting Intelligence.
Table of Contents
This roast machine is currently in the Alpha stage of development at Cropster.
Alpha means that we have limited experience with this particular roast machine. The setup instructions below have yet to be confirmed by the manufacturer. Therefore, the configuration in this article may not work across the entire model range.
If you have not received an invitation to join the beta program for this integration, but are keen on participating and testing out this new feature, please sign up here.
Once the connection is established, you may encounter some daily use flaws. It will be necessary to share such feedback with us, so please let us know if you encounter any unexpected behaviour.
We will be happy to assist in resolving any issues you may encounter or propose alternative connection options.

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?
-
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.
