What is RS-232?

RS232, short for Recommended Standard 232, is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As it obtains the voltage for the path used for the data exchange between the devices. It is used in serial communication up to 50 feet with the rate of 1.492kbps. RS232 is used for connecting Data Transmission Equipment (DTE) and Data Communication Equipment (DCE).

The protocol contains three command sections:

  • Set-Function
  • Get-Function
  • Remote control pass-through mode

NOTE: Below, “PC” represents all the control units that can send or receive the RS-232 protocol command.
