Added a DSM30 Sounder

[mlucitt]

I was running a P319 600W transducer straight to a Raymarine ST60+ Depth instrument with no problems. My chart plotter is a Raymarine C80 and I am using a Raymarine Smartpilot X30 autohelm, all on NMEA 0183 (I know, old school). I recently installed a Raymarine DSM 30 sounder to get a better picture of the bottom contour rather than just the depth in feet. I also bought a new B117 600W transducer. My question is how do I incorporate the DSM 30? Do I have to remove the transducer connections on the back of the ST60+ Depth instrument and re-connect them to the DSM 30? Should I scrap the P319 (no connector on the end of the cable) and just use the B117 with the connector plugged into the DSM 30? (Will this drive the ST60+ Depth instrument through the NMEA 0183 network?) Or, should I install the B117 as a second transducer straight to the DSM 30 and leave the P319 connected to the ST60+ Depth instrument?
