After a little detour back to Lowrance for the HDS-8 (dead NMEA port) I was finally able to finish up the installation on my Sabre.HDS mounted at the console, LSS Box in the Starboard rod locker, SS transducer on the SM jackplate. I connected the existing LMS520c with Ethernet to the LSS Box so I could use the existing 200khz transducers bow and stern. NMEA 2000 network connects HDS, 520, 510, and LGC4000 to share GPS and waypoints. Heres the link to the photos. Cant wait to try it out.http://RazorCat.u.yuku.com/album/view/aid/415749
