This roast machine is currently in the Alpha stage of development at Cropster.

Alpha means that we have limited experience with the Amprobe TMD-56 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 behavior.

We will be happy to assist in resolving any issues you may encounter or propose alternative connection options.

 

 

We recommend reviewing Amprobe's user manual before proceeding with the steps provided in this article.

Troubleshooting

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

  • Is the Amprobe meter connected to the computer?
  • Is the correct serial port within 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.

 

Driver for the USB serial converter

If you cannot select the correct serial port within the RI's Serial port field, your computer may not have the appropriate driver needed to recognize the serial converter's physical connection.

Please reach out to support.cropster.com and attach the following information relevant to the USB serial converter used:

  • Brand and model
  • Serial number
  • Picture of the serial converter
  • RI log files

A Cropster representative will assess the information and assist in providing the required driver for the USB serial converter used.


Congratulations! You have successfully set up the Cropster Roasting Intelligence.

Your opinion matters. If you have further questions, feedback, or concerns, please submit a support ticket directly from support.cropster.com.
