I am trying to build a cellular based engine data upload box based on a raspberry pico. The engine data comes from a GEA 71, which has an RS-485 output on it. Also would like to be able to use the GEA 24. I believe I can just tap off of this with something like the below. Curious if anyone has done anything similar.
