Added a DSM30 Sounder

So, if I understand your response, I should disconnect the transducer leads from the back of my ST60+ depth instrument but leave the Seatalk bus connected. Then, run the (P319 or B117) transducer cable connection to the DSM 30 sensor input. This will transmit the 50kHz/200kHz depth Seatalk bus signal to the plotter to display the bottom profile and also to the ST60+ depth instrument (digits only). Sorry to ask for specifics but I am a very old man.
