I have attempted to connect 2 Furuno RDP139 using Furuno Navnet Quick reference guide multiple configurations. The Host name Radar (master) has program 1020.3 and the Host plotter has program 1017. I am able to see the radar on both screens but when I try to access the plotter they are different. What should I check for? Can you send me program 1020.3 and the procedure to download it so that both units have the same program? Thank you
