[TG] [TG11] How to connect es78 to DSM30, b744v, and more

[Markusmcdowell]

My old C120 went belly up and I bought an es78. I have the following existing devices that were connected to the c120

DSM30 with a B744V transducer
RayMarine 2D 18” 2 kW Radome Scanner
External GPS (?)
Uniden 415 marine radio with NMEA 0183 input)

Is it possible for me to connect the transducer and the radar to the es78? If so, what is required (cable?). Would also be nice to hook up the radio; I dont think I need the external GPS — the internal es78 GPS seems to work just as well.

The es78 came with a CT100 transom mount transducer, but the B744V is already installed as a through-hull, and I am assuming it is the better of the two?

I have searched the boards and on found clear answers to any of these questions.

Thank you for any help anyone can offer.
