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