Renesas' half duplex and full duplex RS-485/RS-422 transceivers are available in a variety of speed grades to address any application needing reliable data transmission over twisted pair wiring.
RS-485 uses differential signals to enable long-distance data transmission, even in noisy environments. Also, the conventional RS-422 has been improved and its functionality has been expanded. RS-485 allows the use of up to 32 devices on the same data line. All of the slave devices on the RS-485 bus can communicate with the other 32 slave devices without having to go through the master device.
