[CA] Networked Axiom's

Here is the set up
2 AX 9's at the helm, 1 Ax 7 at the stern, Quantum radar, & Evo 200 AP.
All 3 Ax's & radar are networked via Raynet RS5.
One of the 9's at the helm is assigned as the data master. The DM is connected to the RV100 transducer & also to the Sea-talkNG network with the AP.

Here is the issue.
The AX 7 at the stern is not able to control the AP and is not seeing the sonar. When I slide from the left side of the screen the only option is Data.
Not Data 1,2 & AP like the other 2 MFD's. However it is seeing the other MFD's when you go to settings/network.

I swapped the A7 & secondary A9 to see if it was possibly a network wire issue. The A9 was fully functional at the stern and when I moved the A7 to the helm the issue remained with that unit.

Thank you in advance for your help.
