[CA] [CA11] Failing 125 GPS and E80 MFD

[Camwhit_boc40]

My instruments include the E80 MFD, ST60+ graphic display, ST60+ wind & close hauled wind instrument, ST60+ tridata instrument, wind transducer, depth transducer, and speed through water transducer, and Seatalk HS switch. There may be other devices, but I think this covers the bulk of it.

I have now installed the Seatalk to Seatalk Ng converter with the required 12v power back to the main panel. I have also purchased and installed the new 150 GPS.

As instructed, I removed the Seatalk alarm cable from the back of the E80. Now the only connection to the E80 is the power cable.

The wiring coming into the R55006 appears to be from the tridata and then some other Seatalk instrument that I have not been able to identify.

I’m not sure how to tie in the new Seatalk converter and GPS to the old Seatalk system. Referring back to the FAQ diagram referenced above, it seems like I may need the D244 distribution block that my system does not appear to have? Please advise as to the next steps.
