The issue
Connecting the USB cable from one of the roast machine's barrels to a different port in the computer may reassign/rename the Serial port.
Because of the serial port reassignment, the Roasting Intelligence (RI) cannot load the serial port saved previously, because it has changed, leading to No sources connected.
To address the issue, and communicate with the serial port once more, select the serial port referring to the connection of the barrel, from the RI instance where you do not have temperatures.
If you are unsure which serial port refers to which barrel from the roast machine, we recommend identifying the serial port.
Identifying the serial port
USB-connected multi barrel roast machines, have a serial port for each barrel, that can connect to a computer.
If you would like to ensure that you have linked the machine's barrel(s) to the correct instances of the RI, we recommend identifying the serial port referring to each of the machine's barrels.
- Navigate to
Preferences > Machine tab. - Under Machine > Configuration, identify which barrel is selected (e.g., Carmomaq Laboratto Barrel 1).
- Switch to the Measurements tab. Verify that the option Generic Modbus over serial port is selected from the dropdown for all measurements.
- Navigate back to the Machine > Configuration tab.
- Select the Gear icon in the Connector setup.
-
Click on the Serial port dropdown. Take note of the serial port options that appear, e.g. COM3 and COM5.
The serial ports available from the above picture were taken on a Windows computer, and may differ on your computer. - Refer to the barrel selected from the Machine field (e.g., Carmomaq Laboratto Barrel 1) and disconnect the USB cable corresponding to the barrel. If you've selected Barrel 1, undo the physical USB connection for the Laboratto's Barrel 1.
- Click OK.
- Click Save to finalize the changes.
-
Continue with selecting the serial port.
The serial port referring to the disconnected barrel does not display anymore. e.g. if serial port COM3 disappears, then COM3 is the serial port referring to Arc Roaster Barrel 1.
Selecting the Serial port
- Reconnect the barrel's USB cable to the computer, and click the Update button.
- Select the Serial port option, referring to the barrel's connection. If you haven't already, identify the serial port.
- Click Save to confirm the changes. The RI instance requires a restart to apply the settings.
Repeat the steps from the top to identify the serial port for more of your machine's barrels.
