Replacing s2 with ev-200

[Chuck - Raymarine - Moderator]

Rip,

Q1: There seemed to be an implication that only one E80 can be connected to the bus "connect the master" - is that the case?
A2: Only the Data Master need be interfaced to the SeaTalkng / NMEA 2000 backbone. Should any other E-Series Classic MFDs be interfaced to the SeaTalkng backbone, then these MFDs will ignore the SeaTalkng interface until such time as they have been configured as the system's Data Master MFD.

Q2: Both are also connected via HS, as is the DSM (which I may deep 6) and HD Radome. I like being able to change masters on the fly so as not to have to go to the flybridge in bad weather to turn on the master.
A2: This would remain possible if both MFDs were interfaced to the SeaTalkng backbone. See the response to Q1.

Q3: I had planned to have the ST - STNG kit at the lower station with the ST bus cable (connected terminal strip with all the ST devices that are presently wired to the s2) and the lower E80. Then extend the backbone to the FB and add a 5 way connector there (just for the E80 and the p70).
A3: This plan is valid. As indicated previously, the MFD(s) should be disconnected from the SeaTalk bus. Also as indicated within the previously referenced FAQ, the SeaTalk bus will be disconnected from its present source of power.
