As the screen on the Yamaha TF1 is currently broken, use the TF Editor app on the studio Mac instead. The app mirrors the TF1's screen, allowing you to load scenes, configure channels, or make other edits.
Open the TF Editor app.
Select "TF1" as the mixer type
Connect the TF1 mixing console
On the left pane, click on the "OFFLINE" button
Select "Yamaha TF" and click on "Connect" (fig 1.1). Leave administrator password blank.
If Yamaha TF doesn't appear as an available device, click on the "Direct IP" button
Enter 192.168.02 (fig 1.2) and click on "Connect".
See troubleshooting below if connection fails.
You should now be connected to the TF1 mixing console.
Fig 1.1 Yamaha TF should appear as a device
Fig 1.2 Connecting directly using IP
The Mac's IP settings should already be configured to find the mixer on the network. If the mixer isn't showing up or connecting via direct IP, you may have to reconfigure it to the right settings.
Navigate to Settings>Network>Ethernet
Click on "Details..." then select TCP/IP in the left pane
Configure IPv4 manually to IP address 192.168.0.10 and subnet mask 255.255.255.0 (fig 2.1)
You should see a green dot with the word "Connected" underneath "Ethernet"
Repeat connection steps in TF Editor
