[CA] Sharing between 2 MFDs

[James Hudson]

When I bought my boat a few years ago it came with a DX600 fish finder and RC435 plotter. I replaced the DX600 with an A67 mfd and CP300 sonar and 1kw transducer. I now want to replace the RC435 with a A6x mfd. Although no longer made I can get an A68. I will install a HS5 network switch to enable sharing. I intend to run the A67 as the master with the chart card in this mfd.
I have a few of questions.
If I use the A67 for sonar will the A68 display the charts OK?
The A68 comes with Downvision. Could I display the sonar from the CP300 on the A68 and chart on the A67?
If I also installed the CPT100 transducer I know I’m likely to get interference with the CP300. Can I select which sonar is active and be able to use either sonar depending on situation?
