Overview

You can manage BRAVIA Professional Display from your PC via RS-232C.

To use this function, you need to set the RS232C control to Via serial port:

• 1. [HOME] Settings
  2. RS232C control
  3. Via serial port

You must then switch to Normal mode or Pro mode because this function does not work in Pro settings mode when Via serial port is set to a setting other than Via HDMI port.
