Helix 5 si multiple tranducers
Tracker22:
Newb here.
I have a xnt 9 di t mounted in the front of my kayak and I just got the helix5 transducer xnt 9 si 180t which will be transom mounted.
Can I connect both transducers via a y cable?
Why? I'm just trying to eliminate the delay on sonar/di while maintaining the si.
Bob B:
There are 2 types of Y cables .... one is intended to get the 2D from a secondary transducer, and the other is intended to connect 2 SI transducers to use one on each side of the boat.
I don't know for sure if the pin-out of the DI transdcuer cable would allow getting the 2D from it with a Y cable, it probably will, but I'm not sure if that's your goal.....Rickie will probably check in later to let you know for sure.
Rickie and some others have gotten a lot more creative with transducer connections than I have.

I'm not sure what you mean by "delay on Sonar/DI while maintaining SI" ...
There are certain circumstances where the DI xducers can be used on a SI unit ...all are unconventional ...
Please explain further what you are trying to accomplish ...

Tracker22:
What I've been told is that when using di/sonar/2d on a transom the image your seeing has already passed. I already have a di/sonar/2d transducer mounted near the front of my kayak. Due to the fact that I don't have a safe place for the si transducer near the front I am placing it on the transom. And since I already have the forward mounted transducer I want to utilize it, thus eliminating some of the di/sonar/2d lag.
Am I wrong?
rnvinc:
I understand now ... The delay you mention is that the Sonar reading from the transom is already behind you ...
There are a couple of possible scenarios to use the XNT 9 DI T on the HELIX SI unit ...
Scenario 1 ...: Use the AS SIDB Y cable that Bob mentioned ...
*SI/blended DI from the SI xducer/ and Temp would come from the transom mounted XNT 9 SI 180 T ...
*2d would come from the front mounted XNT 9 DI T (only the 200kHz 2d would give any acceptable 2d returns because the 455kHz 2d frequency capability of the XNT 9 DI T is not supported by the HELIX SI 2d transmitter) ...

Scenario 2 ...: Use the HB TS3 switch ...

*2d/SI/blended DI from the SI xducer/ and Temp would come from the transom mounted XNT 9 SI 180 T when the HB TS3 switch is set to position 1 ...
*2d/right SI/dedicated DI/ and Temp would come from the front mounted XNT 9 DI T when the HB TS3 switch is set to position 2 ... (Note: left SI would be blank because the XNT 9 DI T does not have a wire channel to line up with the left SI transmitter in the HELIX SI) ...
