Phidget USB Has No COM Port
Summary
Phidget USB setups do not use a COM port in Rostoc. Rostoc talks to the Phidget USB device directly, so check the Phidgets driver or control panel instead.
Steps
- Connect the Phidget interface and probes by USB.
- Install the Phidgets OS package/driver if needed.
- Confirm the Phidgets Control Panel or driver can see the device.
- In Rostoc, choose the Phidget machine/module entry. There is no COM port to choose for Phidget USB.
- Check that probes are connected to the expected channels.
- If no Phidget appears at all, the roaster may be the version sold with the maker's own controller rather than a Phidget board. Mill City Roasters, Diedrich, and VNT models are in the catalog both ways; choose the non-Phidget entry.
- If a serial number is saved in the machine settings, it must be the 5-6 digit serial on the device label, not the four-digit model number on the board. Leave it blank to use whichever Phidget is attached.
