There is an interesting discussion here https://forum.arduino.cc/t/interfacing-f.../27?page=2 from someone reverse engineering a depth sounder.
The bottom line is that unless the sounder is actually "smart", you are going to need a circuit that generates the pulse and receives it. Since this is an old model, I think it's unlikely that it is anything more than a transmitter and receiver, needing something else to generate, receive, and interpret the pulses.
