Welcome to the Raymarine Forum oricohen,

Please create a a system diagram (hand drawn will generally suffice) identifying the makes and models of each of the marine electronics devices within the system (including computers / tablets running navigational planning / chartplotting applications). The diagram should additionally identify how these devices have been interfaced to one another. Please attach, scan, or take a photo of your system diagram and attach it to a reply to this thread.
