[LW] [LW11] Network design - how to prevent conflicting data in ST1 network & STng network

[JonasE]

I just rebuilt my ST1 network and upgraded the network to STng including an ST1 to STng converter, an Evolution autopilot with the accessories and an ITC-5. Tried to balance the power as much as I could. But could not get it 100% balanced with all the instruments on the ST1 network. Due to the small size in the network and lack of good power exists in the DC panel as well as future upgrades. I decided to power the ST1 network from the STng network.

I also added an extender on one of the backbone cables for future upgrade to STng of the network to the companionway when I sometime in the future replace the ST60’s.

In the system, there is also an older RN300 GPS in the ST1 network and an e95 plotter in the STng network. I wanted to keep the RN300 for NMEA 0183 to the VHF and as a backup to the e95.

- How can I make sure that there is no conflict in data and that the RN300 only transmits data to the network when the e95 is not online?

- Do you see any issues with the current network installation?
