I'll attempt to summarize and respond to the various discussion items in one post. To summarize, of course there will be applications for all sorts of additional or different connectors for thrusters, lights, more advanced sonars, etc. All we are trying to standardize on here, however, is a basic connector for communications. Let's keep it simple. We just want to be able to communicate with or between PSUBS and if someone wants a sonar array, video cameras, etc. those simply go through whatever connectors they want to use. Those things are beyond the scope of this proposed standard.
