[CA11] Plugs and General Wiring

Hi, I am wonder if it is possible to buy new termination plugs for your Raystar GPS units... Years ago I connected my unit to a Seatalk1 junction box (removing the Seatalk NG connector)... I am now in the process of upgrading to Seatalk NG and I'd like to refit the connector...

On the wiring front, I have now changed over to a A50D Classic plotter and have NEMA connections available from the following..

A50D Plotter
Smart Heading Unit
230E

Should any of these be connected? and if so which units

Thanks in advance

Tim
