Hi Rüdiger,
Most commonly, transducers either
(1) convert their data onto a standard bus such as NMEA2000, for example https://www.p2marine.com/airmar-nmea2000...ransducers
(2) like (1), but connects to NMEA0183: https://www.p2marine.com/airmar-nmea-018...ransducers
(3) connect to a conversion unit that then has s standard bus interface, example: ITC-5 as component in this package: https://seatech.systems/product/raymarin...systempack
Thus the important question is: which interface standard does your transducers connects to.
Any NMEA0183 device connects to the Raspberry PI running Open Plotter as a serial interface, usually through a serial-to-USB converter.
Something as simple as this oftenn works just fine: https://www.amazon.com/Sipytoph-CP2102-C...s=1&sr=8-4
Or if you have challenges with grounding throughout your boat you may have to resort to using a differential signal based serial to USB converter. This differential signal standard is called RS422. So an RS422-to-USB adaptor like

If your transducers connects to an NMEA2000 network, you need to have an NMEA2000-to-USB adaptor, examples:

or you get a NMEA2000 hat to put on your Raspberry PI:

Enjoy the ride. Lots of things to learn!
