The “new software” to correct the yellow power up/power down sequence isn’t out yet. Just keep it on a switch for now.

Then, I am now baffled on what the heck I downloaded from the Lowrance Active Target support page just five days ago! The filename I got was "ActiveTarget-20.1-64.2.66-Standard-1.riw". I even saw instructions on how to install it onto the AT module. Note I'm NOT confusing this with an update for the MFD as those are "upd" files. An riw file is something completely different - an accessory update file. I recall that release date listed as 4/24/21. As of right now, it has disappeared from the support page. I'm really OCD about managing update files, so I can't imagine I didn't really get the file from the proper page. I bet Lowrance pulled it back down. (Larry, can you comment?)

So, to answer Nitro's question: Yes, keep the yellow wire cut. You mentioned you have a master power switch for the electronics power system. You could put that yellow wire under the same screw as the (fused) red wire for the AT power cable. BUT...then you must realize that your master electronics power switch is what now determines when the AT module is powered on or not. I wouldn't think this to be a big issue; the module typically draws about 1 amp, so it's not going to kill any decent power system in a day of fishing. Just remember you MUST turn off that master switch when done fishing, or a dead battery may result.

Do the update then the Yellow wire will work as it is suppose to.

The file has not disappeared it was moved to Active Target from Transducers.

Here is the update that fixes the yellow wire, read the notes

OK, I missed it somehow.

Steve - keep up, ya' hear? ....the update IS available.

That said, I still have a switch for my AT (if I ever get the one on backorder). In addition to the yellow wire connection, I noted that I may not always want the AT module powered up. What if I'm fishing in a situation where I just don't need or want it? No need to burn power that could be useful for a livewell of 8# bass, lol. My "pre-wire" for the AT has the fused power allocated for the AT going through a dedicated on-off switch at the console. That way, I can use it as an over-ride to keep the AT off if I know I just don't need it, but I will be using the units at the bow in other ways.

The reason I ask about the jumper is that if we go that route the AT module will be powered up when I turn on master power even if I am not using AT. It would be preferable to have the FS 9 turn it on so it is only on when I am using AT. My FS 9 is dedicated to Active Target and won't be used for anything else. Thanks again guys for your help.

Sorry for the last post guys I just got the most recent posts when I posted that last comment. I will try the update and then put the wires back together if that doesn't work then I will use the jumper and put a separate switch in it for when I am not using AT. Thanks again for all your help. If I have success in the morning I'll let ya'll know

For your intention to have the FS9/AT in a dedicated use model, the yellow wire connected between the two should be exactly what you need. Just do the update first. BTW, soldering the wire is overkill, and actually not generally preferred in a high-vibration environment. Connect them temporarily (like with an alligator clip jumper wire) for a test after you do the AT module update. Confirming it works as you think it should is a good plan before doing a permanent connection. I suggest a solderless crimp butt connector (color code red for wire size).

I’m behind.

Bad news. I fired up the AT module using the jumper and successfully installed the software update. I powered down and reconnected the yellow wires and powered up the master switch. Turned on the FS 9 and the AT module did not power up. I am just going to install the jumper and put a switch on it so the AT module will be off unless I'm using active target. Thanks to everyone for their help.

Is there possibly a software update for the FS9? I didn't check; did you?

A question for you: You've established that the AT will power up if the yellow wire is connected to the red wire. When you remove the jumper between the two, does the AT power down? If so, that says the AT is working correctly, and also now "listens to" the yellow wire for instruction. If this is true, then the issue has now become the FS 9, which is why I ask if there is a software update for it.

When you did the update did you wait until the unit rebooted internally and said complete or something to that verbage. If this is the case update it again and follow the instructions. This internal reboot can take 3 min sometimes depending on the size of the update.

Here is a video that shows the exact steps and points out where you must wait for the reboot to complete in order for the update to be successful before you exit the process:

Youtube Video for Active Target Update

Yes I waited for the reboot which took a while. First it uploaded the software which was quick and the after a minute or two it started rebooting which took a while. Then it said reboot complete or something to that effect I'll check out the video Thanks

Thanks again guys. I got to spend yesterday on the water trying out the Active Target. I know I have a lot to learn but so far I am thrilled with the ease of operation and the detail. On several occasions I actually saw the fish take the bait. Also saw fish look at the bait and swim on. It seems to help immensely with suspended fish. Incredible, just one more arrow in the quiver.

You're making me miss mine that I haven't even gotten yet. When I installed new wiring for the latest electronics update, I positioned dedicated power and Ethernet cables for the intended module location. I wanted to make the effort to complete the installation minimal for the day the box shows up.
