Networking HDS 5 to HDS 7

Recommended Posts


I am trying to network a HDS 5 to a HDS 7. I have connected the two units with the NMEA 2000 expansion kit with the black connectors.

I used the 2 foot extension and hooked to the middle of a "T" connector. I used the 15 foot cable and hooked to the middle of the other "T" connector. I hooked both "T" connectors together and then capped the ends of the "T" connectors with the 120 ohm terminator. Checked each unit to make sure the send and receive option was checked.

Neither unit receives waypoints. Not sure where to go from here. Am I missing a step somewhere along the line? Any advice would be great.

fishwater is on the right track, the way you described your network you are missing the needed power node

Thanks for the response PerchJerker and fishwater. I believe you are correct after doing some extensive research on this.

Actually what I did was returned the cables I had a bought the Lowrance Ethext-15YL. It is an Ethernet extension cable with the yellow connectors. I hooked it up to the yellow posts on the back of the units and turned off the "network sonar" option in the main network menu. Seems to be working great! Waypoints are transferring wonderfully. Can't wait to hit the lake and try it out for real (garage doesn't count :))

Thanks again for your replies,

    • Good job!  I have never found any Blacks so they look a little different.  Can you take a picture of what they look like cut in half? They look a little scary like False Morel's 
    • I picked for about 2 hours this morning. I'm not exactly haw many I got but its enough for a couple meals. I'm going to chop some of these up and mix with some cream cheese, feta cheese and garlic chives and then stuff some chicken breasts and cook them on the grill. The little bit of rain that we got last week helped the shrooms pop but it really didn't do much else for the woods besides help the mosquito's hatch. There were so many they licked the bug spray off first then swarmed. I found the mushrooms all over, North, South, East and West facing hills. Normally spot 1 has the best results but this trip it was my second spot. All of them had pretty good size too. Only a few that were in direct sunlight were dried up otherwise they are very firm. Spot 1 is the left container. Don't worry, I use a mesh bag while I'm out in the woods!
    • Yup.... 6 & 4 for Lead.... 4 & 2 for steel
    • I ended up framing my house, putting on the T&G , and then spray foaming back against the interior, which may be why I am not seeing any movement... I also used pine vs cedar
    • I agree with the guy who agreed with the other guy.
    • Just wait till they come up with the remote submarine drone with 3d high resolution camera that can see through algae and milfoil and transmit to your eyewear in 3d.   I struggle with properly tying a berkley knot......
    • I agree with rundrave. #4 early and #2 shot later in year
    • Yes, 5/16 T&G I installed last fall. I did the same, but I see this summer it's starting to buckle  
    • Adding a 4th wouldn't do much IMO. The map screen is already too small to be useful when screen is split in 3. I added a Helix 7 G2N to use as a map screen. Networked with other 2 units
    • I could always go and spend more money on an additional unit but some of it is like Floyd said. I have a hard enough time watching one screen. I have the app on my phone. I think that lowrance has the ability to split the screen into 4. I just can't believe I'm the only person who would like to see this but maybe I am. It may not be as big a deal once I get more familiar with the unit. Right now I like to look at all the screens to help discern what it is im seeing on the screen.  I appreciate the input!
