Specifications

Requirements

• RTD sensors type PT-100 or PT-1000
• Cropster Connector (=Phidget 1046)
  

Setup options

Depending on your setup and the type of probes, there are two connection options: 

1. Direct connection
2. Dual probe connection

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 allows a simultaneous connection to Cropster and the roaster's readout.

Cropster Connector installation

 

1. Follow the probe cable from the tip of the probe to its end where the wires appear.
   In case of dual probes, take the free end that is not connected to the roaster.
2. Connect two leads of the temperature wires to any Cropster Connector channel with the provided screwdriver.
   On the Connector there are four channels for 4 temperature readouts: 0, 1, 2, 3. Each channel has four terminals. To connect the probe, always use the inner two terminals, marked with + and -.
3. Confirm your PT-100/PT-1000 RTD probe has more than two wires, please use only one red and one white wire. Leave all other cables disconnected and isolate them. 
4. Connect the Cropster Connector via provided USB cable to your computer and proceed with the software setup.

Roasting Intelligence (RI) Setup

Installing the Roasting Intelligence (RI) software

Establishing a connection to the machine

1. If you are setting up RI for the first time, click the Select machine button in the banner at the top or click Preferences > Machine > Configuration bottom left to access the Preferences screen. 
   📚 Learn how to use the keyboard shortcuts in RI.
2. To choose the Roast machine, click on the dropdown menu in the Machine section. 
   

   💡 After selecting the machine from the dropdown menu, the roast machine settings may automatically be filled in. You have the flexibility to edit these settings at any time to ensure they align with the specifications of your roasting machine. 

   📚 Learn how to add a new roast machine. 
3. After selecting the machine all supported measurements will load.
   Change the order of the measurements by using the  Drag and Drop icon and moving it into position.
4. Switch on the measurements you would like to enable and select Resistance temperature detectors (Pt100/Pt1000 RTDs) from the dropdown for the measurements.
   💡 Make your measurement readouts more compact. Choose the size of your measurement readouts by selecting either the Small or Large view for display.
5. Select the Channel.
   💡The channel refers to the port on the Cropster Connector. If the probe wires are connected to port 1, select 1 under channel. 
6. Select the Type of RTD sensors. 
   
7. Click Save to finalize the changes. 

After saving the changes, RI will automatically restart. If the setup was successful, you will see the temperature values displayed on the right-hand side of the RI screen following the restart.

Troubleshooting

If the RI 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 Phidgets driver installed?
• Mac only: has the Phidgets driver been enabled in the Mac's Security & Privacy settings?
