I'm not looking for someone to completely write a complete circuit/component for me as I'd like to learn but I seem to be having a problem wrapping my head around what I'm trying to do so help pointing me in the right direction so I can order some components and start pluging things together to learn is what I'm looking for.
Would like to bread board this. Once I build some prototypes and learn what I'm doing when I'll build a schematic with surface mount components to make it smaller
I am pretty sure the MAX485 is what I want to use for what I'm trying to do. Would be 2 one as a transmitter and one as a receiver
http://datasheets.maximintegrated.com/en/ds/MAX1487-MAX491.pdf
I know that the input voltage could be as low as 4v and as high as 36v. So I was looking at http://www.diodes.com/_files/datasheets/AZ34063U.pdf (see page 10) as a step-down/step up
It gives examples but I'm not 100% sure that works for me because the voltage in could be as low a 4v which it would then need to step that up to 5v and the high could be 36v so that would need to step it down to 5v to go to the MAX485
The input side of this board will be 3 wires into probably a screw type terminal like what I think is called a EURO connector which would be +V (4v to 36v) -V and a SPI data signal. The output of the MAX485 would be to a RJ45 connector and use 1 pair of the twisted wires. Another pair will send down +V and third pair would send -V over a cat5 cable to another one of these as a receiver.
I started a list on digikey http://www.digikey.com/short/th7rvc I could be wrong on the parts since I'm not 100% sure on using the step-down/step-up component
So first I think we should start with getting the 4v to 36v up or down to 5v On page 10 it shows the example for 24v in and 5v out but I'm not clear that if the V in can be anything I want or if that example will only work with 24v in.
