Wireless 422

Projects General Guidance

I saw something similar asked a while ago but is there a special sketch that I would have to write to uses the following board (Arduino RS422 RS485 Shield - Zihatec GmbH) to wirelessly transmit RS422? I realize that I would need 2 boards and 2 arduinos, basically I am wanting to eliminate a cable that connects 2 devices using RS422 as the communication protocol.

Perhaps the best option would be to use ESP8266 (ESP01) and SN75176 chip

RS485 is the signalling voltages, so all you need to do is eliminate the rs422 interface, an send the data to/from a wireless tx/rx exactly the same way.

RS422 doesn’t define a protocol, that’s done upstream by the program as it send and receives the dara
