Carrying Serial Devices into the Future


Go through the history of serial devices and their future.

In the lab, and on the test bench, digital data was carried by, first, RS-232 cables. RS-232, or Recommended Standard 232, was an EIA standard for asynchronous data communication that provided bidirectional communication between two devices. From the early 1970s, IEEE established a standard for multi-drop serial communication that was similar to RS-232, but would allow up to 15 devices to communicate with each other over the same cable. This is known as RS-485.
