Link another unit to a57d

[s281sc74]

Currently I use an a57d in split screen for GPS and fish finder. I would like to link another unit to my a57d so I can run GPS on one and fish finder on another. Is this possible? If so what parts do I need? I would like a 6 to 7 inch or bigger screen.

Welcome to the Raymarine Forum s281sc74,

Please note that Raymarine ended production and sales of A-Series Classic MFDs several years ago. Please additionally note that while it would be possible to interface a pair of A-Series Classic MFDs as a spur to a powered and properly terminated SeaTalkng / NMEA 2000 backbone to support sharing of some numerical (ex. lat, lon, SOG, COG, depth, etc.), navigational, and system state data, these MFDs were neither designed to share cartography nor fishfinder imagery within another MFDs (including another A-Series Classic MFD). While this may be satisfactory for you stated needs, I need to make this point clear.
