Amprobe TMD-56 - Roasting Intelligence (RI) Setup (alpha)

In this article, you will learn how to configure an Amprobe TMD-56 digital thermometer, with Cropster's Roasting Intelligence.

This integration is currently in alpha stages at Cropster. If you haven’t been invited to participate in testing this integration, but you are interested, please sign up here.

Alpha means that, at Cropster, we have had minimal experience with the Amprobe TMD-56. Therefore, contact with the machine's manufacturer may be required to clarify, and commence the beta program for the Amprobe TMD-56. Once we have achieved a connection with your machine, using the Amprobe TMD-56, you may come across some flaws under everyday conditions. Hence, it will be necessary that you share feedback with us, and let us know whenever you come across any unexpected behavior.

The setup instructions, below, have yet to be confirmed by the roast machine's manufacturer. Cropster does not explicitly recommend the procedure outlined in this manual. Your Cropster support person will gladly recommend you different connection options for such machines.

Note: We recommend reviewing the Amprobe's User Manual, before proceeding with the steps provided in this article.
