Legal Note

Please read this installation and configuration guide carefully, as any mishandling could lead to permanent device damage.

By connecting a Phidget device or temperature probe to any computer or by installing Cropster’s Roasting Intelligence (RI) software, the user agrees to release Cropster from any liability and assumes any possible risk related to using this measuring device and/or software. Cropster's terms of service apply.

Cropster cannot advise on the installation of the hardware. To ensure safety when installing any hardware on your machine. We recommend consulting with a technician who can help with the installation. 

 


Specifications

Requirements

 

Learn how to identify the Thermocouple type. 

 

 

  • Ungrounded Digital Thermocouples Type K, J, T, or E
  • Cropster Connector (Phidget 1048)
  • Splicing wire (ad-hoc)

Setup options
 

Direct connection
 

  • A direct connection applies when adding new probes independently from the roaster's readout. 
  • The newly added probe can be connected directly to the Cropster Connector. 
     


Dual connection
 

  • A dual connection applies when the roaster is equipped with a dual probe. 
  • A dual probe is a probe with two sensors inside the hull and two pairs of wires that allow a simultaneous connection to Cropster and the roaster's readout.


Splicing connection

 

⚠️ Hardware splicing is strongly discouraged. We do not recommend hardware connection via splicing due to significant safety and equipment risks. If you proceed against this recommendation, you must power off and unplug your roasting machine before attempting the connection. 

 
 


Cropster Connector installation

 

⚠️  Disconnect the USB cable from the Cropster Connector and turn off your roast machine during the hardware installation.

 

 

  1. Follow the probe cable from the tip of the probe to its end, where the two wires appear.
    In the case of dual probes, take the free end that is not connected to the roast machine.
  2. Connect the two wires to any port of the Cropster Connector (e.g., 0/G, 1/G, 2/G, 3/G) with the provided screwdriver, as shown in the table below.
  3. Connect the Cropster Connector via the provided USB cable.
  4. Proceed with the Roasting Intelligence setup.

  1. SelectPreferences > Machine > Configuration
  2. To choose the Roast machine, click on the dropdown menu in the Machine section.
  3. Click the + Add connector option to choose your connector from the dropdown list.
  4. Select Temperature sensor (Ungrounded K/J/E/T-Type Thermocouples) from the dropdown. 
  5. Click Select to add the connector.
  6. Navigate to the Machine > Measurements tab. All supported measurements will be displayed.
  7. To activate the measurements, simply click the green toggle button.
  8. Enable the desired measurements and choose the Temperature sensor (Ungrounded K/J/E/T-type Thermocouples) as the connector type. (Optional) Click the toggle button to turn on (or off) the Rate of Rise (RoR) curve for your measurements.
  9. Select the Channel.
    The channel refers to the ports on the Cropster Connector. If the probe wires are connected to port 1/G, select 1 under the channel. 
  10. Select the Type of thermocouple.
  11. (Optional) Click the toggle button to turn on (or off) the Rate of Rise (RoR) curve for your measurements.
  12. (Optional) Change the order of the measurements by using theDrag and Drop icon and move it into position.

  14. Restart Roasting Intelligence. If the setup was successful, you will see the temperature values displayed on the right-hand side of the screen following the restart.

     

Learn more about the Roasting Intelligence Preferences. 

 


Troubleshooting

If Roasting Intelligence indicates No source connected and/or you cannot see any measurements, please check the following: 

  • Is the Cropster Connector connected to the computer? 
  • Is the Phidget driver installed?
  • Mac only: Has the Phidget driver been enabled on the Mac's Security & Privacy settings?

 

If Roasting Intelligence shows negative temperature readings, you will have to swap the wires on the board from “G” to “0” (or 1, 2, 3) and the other way round.
