B175L + B175H on TZT12F

[mattology]

Hello

TZT12F can fire B265LH which is a low and high chirp.

B175H is the same high element as B265LH high element. no problem there

B175L is a low element that is similar to B265LH low element, but a little wider coverage.

I have a smaller boat so fairings and pocket mount is unfortunately not going to work well for me.

My DFF3D transducer is already transom mount, so i am unsure of how much more room i have on the starboard transom for a TM265LH.

How would I wire B175L + B175H ? What would i configure TZT12F as ?

Hello,

I would recommend ordering both transducers without a connector on it, so it will come with bare wires off of the transducers. You will wire both transducers into the TZT3 transducers pigtail cable (https://furunousa.com/en/products/tz3-12p-pgt) and plug the other end into the back of the TZT3 transducer port (XDR).

The bare wire adapter part your referenced appears to be intended for a single cable bare wire dual element transducer, not two separate cables from a B175H and B175L.

I have a B175L and B175H as the original post is proposing. Last summer when my system was installed, there were no adapters available yet. We used two of the 10pin to 12 pin adapters shipped with the TZT 3, cut off the 10 pin connector, and wired one of the transducer cables to each and then plugged one into each of the two TZT 16s I have at the helm. That worked fine except you end up with separate low and high frequency sonars.

What you propose might work fine except the TID wires cannot be used so the transducer configuration would have to be done manually. The new Y cable doesn't seem to use the TID wires so it must also require manual configuration to use two transducers into one port.

The cable was designed for older non 12pin bare wire B265LH or B275LHW transducer that have a high and a low side to the transducer. So it will have wires for two transducer.

On the 12pin transducer cable, it has an XID (orange wire). But being you have two separate transducer, you will have to manual go in there and setup the one that isn't connected. Here a link to the pin out of the cable. The cable was not intended for this but can be used in this way as it has a wiring for two sides.

I guess my analysis was correct. Now you are making me think I should redo my transducer connections with the new TZ3-12P-PGT plug so that I can have a single TZT3 16 drive both frequencies and be able to do high/low side by side in one window, which is the one capability I lost by having each of my two MFDs driving one of the single frequency transducers.

Here is an excessively technical question for you: if the internal TZT3 sounder is driving a dual frequency transducer, does it affect the timing of the transmissions versus having just one frequency? The reason I ask is I wonder if connecting both transducers to one MFD would possibly reduce the interference I get between the HF and my DFF-3D. I know it would be better to install KP cables but so far that is not possible with the internal TZT3 sounder absent a DI-FFAMP black box.

The correct way to do this configuration would be to wait on v2 software and the Y cable designed to support this pair of transducers. While manually wiring it might work, you will still be lying to the software of the unit and might not get as good of results. V2 software should be on the street sometime late next week.

There are a few of us on the edge of our seats waiting to see what this update will bring. :furuno

I looked at the wiring diagram for the Y cable AIR-040-406-10. It clearly shows that the TID wires are not used on the 12 pin plug that goes into the port on the MFD.

Is there another Y cable in the works? Without the TID wire, there is no way the transducer could be configured except manually so I am confused by your comment. I don't see how the automatic configuration would be able to handle two TID signals from two different transducers. on a single input wire I think you were in communication with my boat builder when he installed my TZT3s last spring and he was advised to go with connecting one transducer into each of my two TZT 3s and use the TID wire. My units do recognize the B175H and B175L correctly in auto configuration but each only has one transducer connected. Thanks.

There will a select group of pairs pre-programmed into the unit for configuration. The Y cable will not be using TID.
