hey guys a few questions about the wiring for (2) Lowrance HDS7 Touch units.

 

- The yellow wire that is the cable bundle with the red and black wire, do i use this? Do i connect this to the yellow wire of the 2nds HDS7? or do i just cut it off and tape over it and disregard.

 

- I am using an Ethernet cable to link the two units together so they will share structure scan, i want the front unit to run off the built in sonar in the minnkota trolling motor and the rear unit to run off the lowrance transducer mounted on the rear of the boat. can i achieve this by simple hooking each transducer to the corresponding HDS? Or will the Ethernet cable make both units run off the rear transducer?

 

- what are these two sensors shown below? Are these from an old fish finder or do these calculate the speed for the main console? Do i need either of these anymore?

 

appreciate the help!

 

The yellow wire is the 'wake-up' wire and you can use it to have other devices turn ON when you fire the HDS.

Everything will work as you like and all you need to do is select where each unit gets its sonar data from. Do all this in the Network menu.

 

The left sensor is a speed paddle wheel and the one on the right is a pitot pickup for a speedometer.

Thanks Ed,

 

So the speed paddle and the pilot pickup, are those used for the dash speedometer? I'm trying to determine is they are for the dash of an old fish finder that was previously on the boat.

The pitot should have a small rubber tube that goes to the back of the speedometer. The paddle wheel will have an electrical connector on the end. You do not need either of those with your HDS units. The GPS speed will be far mor accurate than either of those sensore.
