RS-232 follows the standard communication process and is used as a computer port. It transmits data by following full-duplex mode, and one transmission is directed by utilizing two wires apiece. RS-422 takes assistance of twisted pair cable at the two ends for sending data. The relationship between cable length and signaling rate is proportional, which means the signaling rate becomes slower concerning the increase of cable length. This type of serial communication has the capability of driving the output current is 150 mA.It needs at least four wires for sending data and follows the point-to-point transmission method. ![]() The maximum data rate of RS-422 for 50 feet distance is 10 MBPS.This type of serial communication is capable of sending the data at a maximum distance of 4000 feet with a speed of 100 kbps.RS 422 is eligible to transmit data by following full-duplex and half-duplex communication mode.The data can be transmitted from one transmitter, but at the other end, there may be 10 receivers.It uses a single-ended multi-drop cable for transmitting data.RS-422 mentions electrical specifications regarding a digital signaling circuit, it basically represents a technical standard of serial communication.
