Where to start???

Welcome to the Raymarine Forum Darren,

Unfortunately, these products are no longer supported. However, I would recommend starting with the product manuals for each of the items installed onboard. Product Documentation for Raymarine products past and present may be found here. These documents describe how the products should be powered and interfaced to one another and included sample diagrams. While the diagram below is for an hsb2 system, the diagram for hsb systems would only differ in that
- only two hsb displays may be interfaced to one another via hsb cable
- hsb displays may not be interfaced to a DSM250, DSM30, or DSM300,
- hsb displays may not be interfaced to a PC via a hsb2 to PCMCIA Interface Kit



In short, each display, the autopilot control head, autopilot course computer, and GPS sensor will be interfaced to a powered SeaTalk bus. The white boxes which you have referred to are likely SeaTalk Auxiliary Junction Boxes, meant to supply power to the SeaTalk bus. SeaTalk networking components may be found here. The hsb ports of the two displays were designed to be joined to one another via an appropriate length of hsb Cable to permit the displays to share cartography, fishfinder, and radar data/features between the displays. Hsb Cable may not be available any longer ... however, I would recommend contacting Raymarine Order Services to verify. Please click here to view a FAQ addressing C-Map cartography for use with these displays. Regarding compatible radar transducers, please click here to view a FAQ addressing this subject. This FAQ also included information concerning analog radar cables.
