[CA] [CA11] System upgrades

[Chuck - Raymarine - Moderator]

Welcome to the Leewo,

Q1. do I need to add an additional transducer to connect an a67 chartplotter to the system?
A1. It would only be necessary to interface the MFD to a fishfinder transducer if one desired to use the MFD's Fishfinder application's features. Without a compatible fishfinder transducer, the MFD would simply be limited to reporting numerical depth from the depth instrument which may be interfaced to the MFD.

Q2. can I add a multiplexor to the seatalkng network to connect my Standard Horizon Matrix GX2200 AIS/GPS VHF radio to the network so that all these instruments "talk" to each other?
A2. An Actisense NGW-1-ISO-AIS would typically be recommended for this application to interface a third party VHF Radio/AIS lacking a NMEA 2000 communications interface, but having a 38400 BAUD NMEA 0183 communications interface as a spur to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.

Q3. And will there be any difficulty in adding radar to this network in the future?
A3. I see no reason why. The a-Series MFDs feature an Ethernet communications interface and some a6x MFDs featured a Wi-Fi communications interface through which a radar transducer may communicate with the MFD.
