Connection troubleshooting

Steps when roaster connect fails or temperatures look wrong

Machine settings are stored on that PC. On a new computer:

  • Sign in with the same account
  • Reinstall USB drivers / Phidget Network Server
  • Re-add machine: serial port, IP, slave ID
  • Re-enter capacity and other machine metadata
  1. Settings → Roasting machines → select machine → Connect
  2. Confirm serial port (COM can change after replug)
  3. Baud, slave ID, register addresses match the manual
  4. Empty port list → Serial drivers
  5. Still failing → test on another PC
  6. Fails everywhere → cable, hub, roaster hardware → maker support
  1. Same network for roaster and PC
  2. Did the roaster IP change? Update the app
  3. ping <roaster IP> if allowed by policy
  4. Port 502 blocked by firewall/router?
  5. Giesen/Probat need maker network setup first
  6. Fails on other PCs → roaster, switch, cables
  1. Phidget Control Panel → Network Server Running
  2. Devices tab shows live temperature
  3. App channel map matches Control Panel
  4. Re-read Phidget setup
