Hey guys,

I am not wanting to buy an off the shelf piece of hardware to do this.
I want to try and do it myself.

Fair enough.

What I want to do is take an RS232 signal and pass it through using
ethernet. I have a car wash vacuum and the timer has RS232. I want to
be able to talk to it over more distance than the 232 will allow.

Why ethernet? What sort of distance is involved? RS232 can travel quite a
distance, or you could convert to a differential signalling mode for even
greater distance.

I think there is an IC that should do this. Im thinking maybe a
pre-programmed microcontroller? Can anyone point me in a direction to
get started?

I dont know a lot about ethernet so this is a challenge that I am
wanting to try and accomplish without buying the already designed part.

Certainly a challenge.
