Find Your Machine Connection Settings In Rostoc

Computer SetupReviewed 2026-10-19

Summary

Every setting Rostoc uses to reach your roaster is on one screen. Open Machines from the sidebar (or press G then M) and click Configure on the machine. Its settings open on Connection. The left side holds the connection itself — the address or port and its parameters — and the right side, Stream Configuration, holds each reading Rostoc expects and how it is read. You can read these values off the screen at any time, and a screenshot of that one screen is the fastest way to show support exactly how the machine is set up. A machine's USB serial port and its Bluetooth device are kept on each computer: the roastery PC and a laptop can each use their own port for the same machine without changing the other's. Everything else on the screen is the same on every computer.

Steps

  1. Open Machines from the sidebar, or press G then M. The list shows each machine with its manufacturer, model, and current connection status.
  2. Click Configure on the machine to open its settings. They open on Connection. The sections are listed down the left: Connection, Controls, Style & Colors, and Machine Details.
  3. In Connection, the connection type is shown first, and the fields below it depend on that type.
  4. Network machines using Modbus TCP or UDP show Host, Port, Timeout (ms), and Word Order under Data Encoding.
  5. Serial and RS-485 machines using Modbus RTU or ASCII show, under Serial Port: Port (the COM port on Windows, the serial device on macOS and Linux), Baud Rate, Data Bits, Stop Bits, Parity, and Timeout (ms).
  6. On a second computer, the port list marks the port the machine already uses elsewhere as Recommended when this computer is set to a different one. Pick it to use the same port here. If this computer has no such port, it is listed as Not on this computer and cannot be picked. Choosing a port on one computer never moves another computer off its own. A new serial machine starts with no port ("None selected"); if Rostoc says it "has no port on this computer yet", click Choose its port.
  7. S7 machines show Host, Port, Rack, and Slot. USB, Bluetooth, and manufacturer network machines show their own fields, such as the Bluetooth device or the machine's own port and timeouts.
  8. Look at Stream Configuration on the right for the readings. Each row carries the Label shown on your charts, its Sensor Role, and the Unit the machine sends.
  9. Machines read over Modbus also show Device ID, Register Address, Function Code, Data Type, and Divider — the values a machine manual usually lists for each reading.
  10. To share the setup with support, screenshot the Connection section with both columns visible. Please send a screenshot rather than the diagnostics export: the diagnostics ZIP carries logs and system information, not your machine connection settings.
  11. Click Test Connection to check the settings as they stand. Renaming a machine or changing its settings does not affect roasts you already recorded.
  12. You can save while a roast is recording; the roast keeps recording. If Rostoc says "This change can't be saved while a roast is recording. Stop the roast, then save again.", your edits are still in the form. Stop the roast, then click Save again.
  13. Changing the connection type removes the controls the new connection can't run, and a note under the connection type says what was removed. Switching back restores them. Nothing changes until you click Save.
