Mill City Roasters Phidget setup with Rostoc.

Direct Answer

Rostoc can be tested with selected Mill City Roasters Phidget USB entries, including MCR Phidget, MCR Phidget Delta Controls Port on the Back, and MCR Phidget Shihlin Controls Port on the Back.

Mill City support is exact-setup specific. Some Mill City catalog entries use supported Modbus RTU, while the Phidget entries use an experimental USB sensor path.

• Use a Phidget entry only when the machine really exposes the Phidget USB setup.
• Check the control panel and port location before adding the machine.
• Do not treat Modbus RTU Mill City entries and Phidget USB entries as interchangeable.
• Validate live readings and saved labels before production use.

Covered Mill City entries

The Mill City model name is not enough. The important details are the control panel, connection port, and whether the computer sees a Phidget device or a serial/RS-485 Modbus path.

If you have existing setup screenshots or a `.aset` file, keep them available as evidence. The imported setup still needs to match the Rostoc catalog entry.

• MCR Phidget - experimental Phidget USB logging.
• MCR Phidget Delta Controls Port on the Back - experimental Phidget USB logging.
• MCR Phidget Shihlin Controls Port on the Back - experimental Phidget USB logging.
• Mill City Modbus RTU entries - separate serial or RS-485-style setup paths where the catalog marks them available.

Validation checklist

Start by proving the physical connection. A wrong port or wrong catalog entry can look like a software bug even when Rostoc is behaving correctly.

Rostoc should be validated as a logging workflow first. Continue operating the roaster through normal Mill City controls unless a specific release states otherwise.

• Confirm whether the machine is a Phidget/back-port setup or a Modbus RTU setup.
• Install the Phidgets driver for Phidget entries.
• Close other roasting applications before testing the USB device.
• Compare BT, ET, and any extra channels against the roaster display or expected probe order.
• Save and reopen a test batch to confirm stream labels and chart routing.

Support boundaries

Contact support when the control panel, port location, or connection type is uncertain. A photo of the panel and connection port can be more useful than the roaster size alone.

Start with the machine compatibility guide, the Mill City Roasters catalog page, and the Phidget USB setup docs.
