Two screen operation with NavNet 3D

[Henriquesbri64]

Just purchased a boat with dual screen NavNet 3D & can't for the life of me get the 2nd screen working. The primary screen comes on & is operational but the second screen reads "No Master as detected on the Network". What keys do I hit on the master screen to get the depthfinder functioning on this secondary screen. What keys activate this 2nd screen?

If you have two MFDs (like two MFD8s or MFD12s) they connect by Ethernet network. The master will share it's system id to the slave and it should be working. The fact that your's isn't says that you have a networking problem. How do you have the two connected?
