You can use either network splitters or the new hub. Once we introduced the new SV-NET-HUB, we recommend that over using multiple splitters. The one place where the splitter is handy and still recommended is if you have a backup ADAHRS, since the splitter makes it easy to connect one network cable to the two ADAHRS.
For your requirements we recommend the following (assuming that you have only one display, an ARINC module, an EMS module, and two servos.):
* One SV-NET-Hub
* An SV-NET-3CC to go between the Display and the Hub.
* An SV-NET-3CC to go between the Hub and the ARINC.
* An SV-NET-3CC to go between the Hub and the EMS module.
* An SV-NET-15CP to go between the Display and the ADAHRS.
* Two SV-NET-SERVOS to go between the servos and the Hub.
