Well, its shaping up to be an interesting yet still somewhat disappointing year for freshwater fishing electronics this year. Humminbird, Lowrance and Garmin all three have new products out that have some new (to them) cool features, but nothing revolutionary or that hasnt been expected. And no one brand has all the cool features that together would make a truely remarkable product.Humminbird finally came out with a giant screen unit. The 1197C SI gives the side-imaging a giant 10.4″ screen, looks like its the same width as the 997 but quite a bit taller so maybe itll even fit in the BassCat consoles; but other than that its nothing new over the 997C SI; no high-bandwidth networking, no touchscreen, and appears no industry standard plug-and-play networking with non-Humminbird devices. But still, the side-imaging is WAY cool!Garmin has their 5000 series units which have touchscreen; also, WAY cool. No more arrowing up, down and across nested menus or having multiple button presses to get to new pages or change settings. A LOT safer to mess with while under way! And Garmin was already several years ahead in marine networking with shared networkable sounders and weather data, but still not high enough bandwidth for map sharing, and its still to my knowledge proprietary and not an open or industry standard for mixing the best brands for different functions of radar, gps, weather radar, sonar, etc. But touchscreen is an awesome feature as anyone with a iPhone will tell you.Lowrance wins the award for the MOST cool new stuff this year (but not necessarily the coolest single feature) with their new Navico branded high-speed marine networking. But sadly since its ethernet based it appears as though its hubbed vs a backbone so multiple units and devices apparently will have to have multiple cables even covering the same distance. I dont know for sure though so maybe a snowflake topology with multiple hubs rather than a pure star will work though; well see. Anyhow, its nothing that anyone who noticed the bright yellow hole on the back of last years new units shouldnt have anticipated though but its definitely a step in the right direction. With this came a network sharable remote sounder unit with some advanced high-definition and digitally processed and enhanced sonar images, but still not near as cool as the Humminbird photo-realistic side imaging. But this remote sounder will work with ANY unit with the yellow jack on the back, including the formerly GPS only GlobalMap units; marking a clear departure from previous Lowrance attitude where you have to buy all new units and plugged devices to use any new functionality. Maybe theyre finally coming around. Now if we could just get an industry standard compatible marine network sharable, side-imaging sonar unit that also shares gps maps (not just waypoints, routes, position, etc.) and has a touchscreen then well finally be all set!

Great information there ! There are so many things that can be accomplished with todays technology. Im not too familiar with Humminbird or Garmins network capabilities, but I see where Lowrances new broadband sounder, when combined with a Navicos expansion port switch, you can have all your on board equipment “talking” to one another. The switch is what really makes the system a true network. In this case, a hub would not be used do to collisions of data on the network, but the switch would correct that problem and allow a full 100 megabits of data transfer so there isnt a bandwidth issue. There is also an uplink ethernet port on the broadband sounder where by you would only need one ethernet cable running from say the back of the boat connected to a switch (Navico expansion port) > to the front of the boat where a second switch (Navico expansion port) would be located. All devices could then be connected to the switches with a short run of cable to each switch. It will interesting to see how long it takes the boat builders to start incorporating this technology. Im with you on the touchscreen option as well. I hope thats something Lowrance will offer soon. Brian
Thanks for the clarification Brian. Hub/switch, I was using the term interchangeably though I know theres a difference as you explained. I actually hoped that the switches could actually be linked (i.e. snowflake topology) rather than just a central star or hub and spoke but found no reference to it in a cursory search. At $150 or so for a Navico switch though some may opt for the hub and spoke anyway unless the longer cables are more expensive and theres no generic alternative to them (if you cant tell Im all about standards and open non-proprietary technology ). Do you know if it uses standard cat 5/5e ethernet cables, maybe just with waterproof plugs or something? The $500 for the Navico digital sounder unit though I thought was quite reasonable and it can use existing Lowrance transducers too! Deke[font="]Deke[/font]
Deke, I couldnt agree with you more. The NMEA standards arent really standards at all. Everyone out there seems to be doing their own thing. When it comes to hardware, everything SHOULD be compatible just like PCs, routers, switches etc, but for some reason, they arent. Now software is a different story. I can understand one company using proprietary software but they should ALL physically connect together like a normal network does. AS for the Star topology using a singe switch/concentrator, I think this would be the simplest way to go, but it would create a cabling nightmare for the boat companies. Thats why I liked the fact that you can uplink from one switch to the next using a single cable for the extended run to the front of the boat. To answer your question, I dont know if the cable is a standard cat 5 variety, but in my opinion, it needs to be something a little more durable than that for use in a boat. Personally, I would like to see a cable similar to what a DS3 would run on using a BNC connector but that is probably too cost prohibitive. Im sure whatever they use will be well shielded and hopefully easy to maintain. Thanks again for all your research. I find this networking stuff pretty fascinating myself. Brian
Deke, I found these links which really do a great job of showing how the setup works. I guess the cabling is a 5 pin proprietary connector that Lowrance will use to connect all the devices and switches together. Really a great setup they have here. Notice the extended run from one switch to another in the Multi-Station network diagram. Kind of what I was suggesting in an earlier post. Also, the pics may come out small when you click on the links, just wait for that little orange box with the blue arrows to come up and then maximize the screen. http://primus.lowrance.com/icr/Units/Im … _port1.jpg http://primus.lowrance.com/icr/units/Images/brdbnd1.jpg Brian
