1) I assume the yellow accessory wire from the HDS goes to the LSS yellow to auto turn on the LSS when the HDS is turned on? How many of you have wired it this way BUT also installed a switch?

2) I don't see any way to turn off the 83/200 transducer.

3) What do you guys do when you want to use your HDS out of the water, for example in my garage, when I want to apply updates, plan routes, etc? Just do it, no worries? Anybody knowingly had an 83/200 or LSS issue occur after running it out of the water?

I just have a ducer into the back of the HDS, but I turn sonar off in the menu when messing with the unit out of the water.

I followed the wiring diagram and used the yellow remote wire from my HDS-8 Gen 2 to turn on the LSS-1. The unit works great for a few minutes, then stops working, giving a "NO SOURCE" message on the structurescan screen. There are no LEDS lit on the LSS-1 box. Thoughts anyone?

Make sure you have good ground and positive connections for the LSS. If it (red and black) are wired to a switch like accessory, turn it on. No Source = no power usually.

Yellow wire from the lss module powers the transducer only
The wiring diagram shows that red and black wires from the module should be connected to the battery
For the yellow it says that it should also be connected to the battery (+) with a switch in between or to be connected to the yellow of the HDS
I think that the best way is to connect the HDS yellow to the module yellow and use a switch in between. That way you have the option to stop the transducer at any time and in case that when you are done you forget to switch off the transducer it will be powered off when you shut down your HDS and that will avoid damaging your transducer.
my two cents..

How does powering off your HDS head-unit have anything to do with damaging the LSS transducer, which is connnected to the LSS box?

The yellow wire does not "power" the transducer, but serves as a "wake-up" wire to the LSS-1 box. I've never tested this, but in my previous installation my HDS-10 was connected to my LSS-1 and the yellow wires were connected. My 2nd unit at the bow did not end up having the yellow wire connected for some reason :mad: (one of the several issues of the previous install which I am correcting at the moment...) What you are saying above seems to imply the ethernet switch functionality of the LSS continues to work as long as the LSS-1 box receives power, and only when the HDS head unit sources some voltage onto the yellow wire (or via a switch) that the StructureScan sonar part works..... I've never seen any reference to this behavior and thus am a little surprised/confused by it.

eolos this is not correct. If you don't hook the yellow 'wake-up' wire from the LSS to a switch, the LSS will continue to draw juice (unless of course you have it wired to the MAIN BAT switch). On the same hand, if you wire both yellow's together the LSS will turn on/off when you switch on/off the HDS. The negative to this setup is you can not turn OFF the LSS while the HDS is running. It is best to connect the yellow wire to a switch.

I'm lost on this one. Under what circumstances would you want the LSS off when you're running the HDS? Battery trouble? Stalking fish with VERY good hearing? Solar flares? :grin:

How about trying to track down an interference problem by process of elimination?
How about a malfunction in the LSS?
How about a damaged or broken LSS transducer?
How about just fishing too deep or going too fast for the LSS to be useful?

The wiring is not always easily accessible and lets not get into who doesn't use fuses or circuit breakers.

Also using the HDS on a trailer or lift with the transducer out of the water.

Wrong!
The yellow wire from the lss-1 module does power up the transducer not the module. The module is powered by the red/black
To test this you can connect the module red/black to the battery (leave the yellow disconnected) and connect ethernet to HDS. The Hds will detect your module but you will get a "no source" message (thats the transducer yellow wire no being connected)
The manual suggests that you must connect the yellow from the module to the battery and place a switch in between or just connect the two yellows together without a switch (hds/module)
In the first case you can turn on/off the transducer any time you want but if you forget the switch and even if you power off the HDS the transducer will be still be powered on and that will most probably drain your battery or even worst if you take the boat out of the water you will damage your transducer (you must never operate an transducer out of the water... not for long anyway)
In the second case (two yellows without a switch) you cannot power off the transducer if you want to, while operating the HDS.

eolos this is not correct. If you don't hook the yellow 'wake-up' wire from the LSS to a switch, the LSS will continue to draw juice (unless of course you have it wired to the MAIN BAT switch).

My suggestion was this... instead of following the installation manual...

HDS yellow => switch => LSS-1 module yellow
You can turn on/off the transducer whenever you want to and if by any chance you forget to turn the switch off the transducer will power off when you shut down the HDS

eolos - I'm not saying you are wrong, but it is not how I've understood the yellow wire use on the LSS-1 after a lot of reading and talking with others who have done similar installs..

What you are saying is that if you disconnect the yellow wire, but leave +12V to the LSS-1 box that the "rest" of the LSS-1 box continues to operate (i.e the Ethernet switch functionality, etc). It surprises me that Lowrance would recommend a configuration (yellow wire of HDS<->LSS-1 but leaving +12 to LSS-1) where the +12http://i227.photobucket.com/albums/dd309/ward0625/Misc%20Pic/amflag3.gif stays there full-time if the overall LSS-1 does not effectively turn off else the LSS-1 box would draw down the battery all the time.

I can't confirm or deny at the moment - my config had a LSS-1 with +12V connected hot all the time and the yellow wire connected to my HDS-10 at the console. The HDS-10 is removed when I'm not on the boat, so the yellow wire would then go "dead" (well, at least floating). I always keep my boat on a charger when not in use, so if the LSS-1 was "hot" and drawing power as you say I would not have known it anyway.

Right now all my wires are pulled out of the boat and the units not even there - hopefully by the end of this weekend I'll have most of it back together and I can check out some configurations to prove this out one way or the other. I have been debating what to switch on the LSS, or even if I switch it, so this is a timely and good discussion - if the yellow just turns off the xducer (or the StructureScan circuitry) that is good to know - if it puts the whole thing in a "virtual off" mode, that's important to know as well.

eolos if this is correct then you should receive the same 'No Source' message when you switch off the yellow wire shouldn't you?

I agree with mwardncsu that the yellow wire is needed to wake up the LSS circuitry. This way you have power for full Ethernet functionality within the module with the LSS off.

My new gear gets here on the 3rd so I can also play with the yellow wire to see what messages I get. My previous install had both the HDS and LSS on independent switches.

Got the manual in my hand it says..
Black to ground
Red to + with a fuse
Yellow to + with a switch
Blue not used

I run 2 HDS 5's a M and a X. When I switch off the LSS-1 My X looses GPS from the M
and alerts to that fact.
In my opinion you want the LSS-1 off at cruise speed as you can't read anything anyway. It is a low speed search tool, not a high speed sonar.

But you just highlighted the reason to leave it on at speed - the LSS-1 also serves as the Ethernet switch for multi-unit configurations for most people - you are confirming that when that power to the yellow is dropped the Ethernet switching function is turned off...... hence the yellow is "powering" more than just the xducer, as has been my understanding.

Okay, here is the way to resolve the issue with the LSS1: I will quote it from one of my previous posts. My setup is working 100% proper with the wake up (yellow) cable connected to head unit cable and the radar connected to a switch because by default these items stay on unless wired otherwise or hooked to battery switch.

In my setup, What turns on and off the LSS1 module and sidescan (actually sidescan is controlled by head unit when lss1 is on, otherwise it is off) is the head unit when it is turned on and off (and connected via e-net cable). Power off head unit, and the LSS1 and sidescan are turned off.

3G Radar will stay powered on all the time unless you put it to a switch the way I did. DON'T FORGET THE FUSE!!!!!! (red and yellow wires get connected together to the fuse.) Below is the explanation and pics.


For Example: The Lowrance 3G Radar stays on all the time. Minimal battery drain but still it is on all the time. So a lot of people who did their own installs with weak batteries are going to have a rude awakening. I installed the 3G radar with a switch so when it is off it is off and ONLY on when I turn it on. That is the switch in this picture.

Also, you have to know that the LSS1 Structure Scan is always on. You have to connect the yellow “wake up” cable to either an open accessory switch or the Yellow wire on the HDS unit if you want the Structure scan to be on only when connected to the HDS. I actually visually checked the LSS1 module to see if it is on. With the yellow wire it is only on when the HDS head unit is on. So, read carefully, use a volt meter to check when you think things are off.

That is correct it is acting as the HUB. However I don't care that my HDS 5x sonar doesn't know the GPS location. It can't use it anyway as it is only sonar. All it can do is display it when the HUB is on. In my opinion I think the yellow is the wake up lead.
