I have complete cruiser package of Tacktick instruments and want to get them to read waypoint/VMG to waypoint etc from the Standard Horizon CP590 plotter.
Is it possible to link directly from the CP to the wireless interface using NMEA 0183 cables. If so which input ports do I use on the interface.
Or do I have to use a multiplexer to make the Tactic interface work.

Welcome to the Raymarine Forum Ian,

As you have suggested, interfacing such devices would typically be accomplished via the Tack Tick T122 Wireless Interface. In short, the third party chartplotter's 4800 BAUD NMEA 0183 OUT+ and OUT- leads would in turn be interfaced to the T122 Wireless Interface's NMEA 0183 IN+ and IN- terminals respectively.
