Hi guys, some time ago I tried to understand RS485 connection and how to implement it. I would like to try this again, please understand that I have never worked with RS485 before and dont 100% understand what is needed.
The basic scenario is that I have an electronic level controller with 16 points of indication. Each point has its own detector circuit that is controlled by a TLC3702CP comparator, giving an on or off output. The output is fed into a Darlington array to give outputs for leds and relays.
I would like to use RS485 to power local and remote LED displays for the unit. The are 3 leds per channel and 16 channels. so 48 on / off signals. It is possible to reduce this to 32 signals if need be.
I guess I would need a chip to input the signals into, which then feeds a transceiver. A transceiver and decoder on the remote and local display. I really don't understand any more than that, so any help or guidance would be great.
Mod edit: fixed P/N of comparator
