Dual Station Depth Speed Requirement

I have a requirement to display vessel speed and depth on both the upper helm (bridge) and lower helm positions (dual station). I think the i40 Bidata displays fit the bill if I use the all-in-one depth/speed transducer (this last item is very important to be confirmed as I need a transom mount depth/speed transducer... P/N being on the drawing below).

Please review my drawing below and advise me if you think I have the system connections correct. I also need confirmation that all the P/Ns on my drawing are correct. Thank-you.
