Explanation
RS-232 (Recommended Standard 232) is the classic serial communication standard used when a data acquisition device is physically distant from the computer. It defines voltage levels, timing, and connector pinouts for point-to-point serial data transmission and has been the industry standard for decades in instrumentation and DAQ systems. RS-422 supports differential multi-drop transmission over longer distances, and RS-423 is a single-ended variant - both are less commonly cited as the primary DAQ serial standard. RS-231 does not exist as a recognized standard.
