To control a display (Projector, etc.) through pre-loaded RS232 commands, configure the RS232 port of the DCE-1 according to
the display parameters.

Connect a PC to the DCE-1 according to section "Control the DCE-1".
2.
Configure RS232 parameters of the DCE-1 with the serial port software according to the display parameters. For example:
set the correct baud rate, preload Power-ON and Power-OFF commands in string/hex (refer to the document "API Command
Set_DCE-1).

signal change is detected.
