If you are operating anywhere near these values you must arrange your wiring close to the ideal. For many applications where baud rates are slow (say 9600 baud), and lines are only tens of meters long, this is not essential.

WebThe RS485 protocol is a form of asynchronous serial communication that allows communications bus to connect multiple devices simultaneously. The communication is at half duplex using two wires and common ground. It is faster and covers a wider range as compared to other standards like RS232 etc. Provides a maximum cable length of 1200m. WebApr 22, 2024 · Pondering.. would a normal RS-485 interface work with the C7042? you mention weighting the port.. may one ask in what way? curious as it seems a bit daft to go RS-484(ish) -- USB -- cable -- USB -- Serial (on the arduino). when I could just stick an RS-485 interface and use one of the otherwise unused serial ports the Arduino mega has, … coprococcus probiotika kaufen
