Setting up a connection
There are two ways to connect your roast machine to the network:
Via the network router

- Connect your roaster with an ethernet cable to your network router.
The router assigns an IP address to your roaster. - Make sure that your computer is connected to the local network.
- Proceed with the Roasting Intelligence (RI) Setup.
Via the computer
- Connect the network cable to your roaster's Ethernet port
- Connect the other end to the computer's Ethernet port.
- Proceed with the Network settings.
Network settings
When the roaster is connected to the computer directly, you need to set up a Static IP address.
Identifying IP address
Once the Probat PIII is connected to the network, an IP address will be assigned to your roaster. You will find the IP address from your Probat's display under Preferences > General.
💡The IP address of your Probat differs from this screenshot.
Static IP address configuration - Windows 7, 8, 10
- Navigate to the Control Panel > Network and Sharing Center or Network and Internet > Network Sharing Center.

💡Set a roast with recorded Drum speed data as the Reference and begin replaying your recorded Drum speed changes.
Troubleshooting
If the RI indicates No source connected and/or you cannot see any measurements, please check the following:
- Is the IP address correct?
When using Replay Assist, do not use the Probat Pilot roaster shop or any other temperature-controlling software in parallel.
Any gas/airflow/drum speed changes from a concurrent client disable Replay Assist for the remainder of the roast.
