The steps below will show you how to configure Display Control using RS232. Please note that at this time RS232 is not supported on Raspberry Pi. If you are using a Raspberry Pi, you can use CEC instead.
Refer to the manufacturer's user manual of your Screen to confirm the appropriate serial port settings and power on/off commands. The steps below are based on the serial communication requirements of an NEC LCD Monitor. If your Media Player doesn’t have a serial port you can use a USB to Serial Cable.
For Media Player's running Ubuntu, Rise Player needs to be granted access to the serial ports on the Media Player. To do this, simply run Rise Player Installer on your Media Player and follow the onscreen directions.
Configure the Serial Port
As mentioned above, this guide is based on an NEC LCD and can verify that the settings from Communication Parameter from the NEC LCD External Control documentation. The manufacture of your Screen should have similar documentation.
Test your Serial Port
Once you’ve configured your Serial Port test it is working by sending Power On and Power Off commands to your Screen using a tool like Serial Port Monitor.
