Question Turn off/Disable Sonar

Hello all,

I purchased the HDS-8 Gen2 (83/200 HST-WSBL)/LSS-2 (XDCR SS HD 455/800) bundle recently, and I'm trying to figure out how to disable/turn off sonar while the boat is out of the water without having to unplug both transducer cables.

I read that you can select 'Stop Sonar' in the Sonar Menu to turn off the regular transducer and that you can do the same in the StructureScan Menu for the LSS-2 transducer.

To test this, I went to Pages and selected Sonar+Structure+Down, and as expected, 'Stopped' is displayed on all sonar views. However, I can walk over to the location where the transducers are installed on the transom and clearly hear the ticking noise of the transducers still at work. That can only mean that they are still active and pinging. First I unplugged the HST-WSBL, and I could hear the LSS-2 still ticking. Then I unplugged the LSS-2 and (plugged the HST- back in) could hear the HST-WSBL ticking. Even in Simulation Mode, both transducers are still active and an audible ticking can be heard.

Has anyone else tested this? Why are the transducers still active? They should be disabled while 'Stop Sonar' is selected (blue circle= parameter selected).


Thanks in advance for your help.

I'll have to check my hds 10 now. I stop the sonar when out of the water. Maybe it doesn't do any good.

From the Install manual.
Powering the LSS-1
The LSS-1 power cable has four wires; red (+), black (–), yellow and blue. The
red wire is positive, the black wire is the ground and the yellow wire connects to a
switch.
The blue wire will not be used. Cut it flush and cover the end with a wire nut
or electrical tape.
Connecting LSS-1 to display unit/ethernet network
The LSS-1 has three ethernet ports allowing you to connect it to up to three HDS
units. It can also be connected to an ethernet hub, like the NEP -1.
The LSS-1 comes with a 15 feet ethernet cable, but cable lengths of 6, 15, 25 and 50
feet may be purchased separately.
Black wire
(to negative)
Blue wire
(not used)
Red wire, fused
(to positive)
LSS-1
Power Cable
Yellow wire
(to positive)
Switch (at console)
Yellow wire wakes LSS-1 unit up when turned on. If you leave the LSS-1 powered all the time it will kill your battery.

I have all electronics on a master switch.

Yes you should have everything on breakers or main power switches.

No question, Stop Sonar should prevent power to ducers. I just rechecked this with both networked Touch and Keypad units on my boat, and it works as designed on both 2D and LSS ducers. I have routinely used this feature over the years with a wide variety of units and numerous versions of software, with no issues at all. I don't have an answer as to why your ducers are still functioning when Stop Sonar is selected.

Thanks for all of the responses.

As for wiring, no problems there. Yellow (wake up) wire from LSS-2 and yellow from HDS (head) unit are wired together, run through a switch on the console, then to fuse box to the (+) battery. I also have the red (power) from the SS module going through a switch on the console to the fuse box, then through a breaker on the (+) terminal. With a switch on the SS power, I can simply turn it on and off at will. I do not have to turn the HDS unit off and back on again to power up the SS. All I have to do is flip the (new) power switch on, then flip on the wake-up switch. I can either flip it on and leave it on or simple flip it on and right back off. It's only a one time shot of juice that turns the unit back on anyway.

Now, as for the transducers still making a ticking noise while sonar is 'stopped.' Don't know why they're still ticking away for me. It really isn't a big deal for me though, just an observation I made. All I have to do is simply flip the SS power switch off that I installed on the console and no worries.

Todd, did you happen to walk over to your 83/200 skimmer and listen to see if it was ticking or not? Just curious. Also, did anyone else check? Never heard anything back from Truant.

Everything aside, I finally got a chance to get out on the water and test this puppy. I was relieved to find out everything was functioning properly and that I didn't have a defective unit or have any wiring issues. I was totally blown away by the performance of this unit out of the box. The image quality is just unreal. I spent most of my time just glued to the the HDS screen. If it weren't for the chart showing me where the boat was, then I'd have probably ran ashore a couple times. I found huge schools of bait fish in less than 10 minutes of launching the boat. Found a school of stripers not long after that. Love this unit!

The yellow wire is not fused?
I'd put a fuse in.

I run everything through a fuse box I made and installed. The power for the HDS and LSS-2 also go through a breaker.

Yes I did, and no ticking at all with Stop Sonar selected on any of my ducers.
