We have several devices connected to Modbus network. We bought a new device that can't be tuned and has fixed settings: baudrate=19200, parity=odd, while others have baudrate=38400, parity=none. Is it possible to use them in one network, i.e. first read from old devices, and then reset serial port to read from the new device?
Yes, as long as the devices ignore data encoded with the wrong baud rate.
