I am designing a product (prototype) that consists of many RS485 networked nodes. They will share a common bus. My network will be small on size and doesn't need a very high baud rate. RS485 recommends termination resistors, which I want to add. Now, I wouldn't like to request the user to add these resistors at the ends of the bus, because the user is not expected to be tech-savyy. I was planning to add a termination resistor inside each module in the bus, thus making redundant resistors. In my prototype, I want it to seem that you can "just plug them in"
This means each module has two jacks: one to connect to the bus, and other jack to chain the following module into the bus aswell.
So maybe a higher value resistor could result in a sort of progressive terminator resistor? More modules-->lower overall resistance between A and B.
I have also heard that you can use this standard with only one terminal, if you don't expect noise. Is that true?
