Thread: hb 798

If that is a 798ci HD Si model unit and you are meaning the Ethernet connection, than you will need the AS-EC-QDE Ethernet Adapter for the 700E series units: AS EC QDE
(check with board sponsors for better pricing).

I was referring to the sonar and transducer. The sonar and transducer look to have the same end but only one of those outlets on ff. Do i need a y cable with those two ends? Thanks

Do you have the US2 sonar on your Terrova?
If so and you are wanting to use it with your 798 unit, you will need the MKR-US2-8 cable from Minn Kota to connect them. If you use the US2 transducer you will not have any Si or Di sonar.

Yes i have the terrova with ipilot link and am trying to get it all hooked up with the hb 798

Those are the only two ways you can connect a trolling motor to a Humminbird unit.

I am confused (which is not hard to do when its electronics) do i need to hook the transducer that came with the unit up or do i need to just hook the trolling motor sonar up or both ?

Either or but not both. If you use the built in (us2) you will loose down and side image.

You say the Terrova has iPilot link...but does it have the US2 sonar Xducer in the foot of the TM...??

If it does have the US2 Xducer in the TM..

What Greg is saying is that "if" you want to use the US2 (2d) Xducer that is in the foot of the TM ....then hooking up the US2 to the HB SI series unit will disable the SI/DI function of your SI unit...

The iPilot link is completely different from the sonar functions of the xducers ...in that the iPilot link "talks" to the HB head unit thru the Ethernet cable that Greg listed...

And the "talk" between iPilot link and the HB is only waypoints, routes, tracks, etc,...(not sonar functions)...
