[CA] [CA11] E120 Master/Slave issues

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Kurtzrr,

The reported issue is indicative of a failure within the Ethernet (SeaTalkhs) communications networking components or Ethernet network circuity of one of the MFDs. Please click here to view a FAQ addressing this subject.

Within an Ethernet (SeaTalkhs) network, only one of the system's MFD's may be configured as the system's Data Master MFD. That MFD will be the one which has been interfaced to the SeaTalk bus, as only the MFD which has been configure as the Data Master MFD can communicate with the SeaTalk bus which has been interfaced to its SeaTalk/Alarm port. While it may be possible disconnect the Ethernet network link joining these two MFDs to one another and interface the second MFD to the SeaTalk bus, the MFDs would then no longer be able to share cartography, radar, fishfinder, Sirius Satellite Weather/Radio, or AIS resources.
