4.2 Remote Control Pass-through mode
When PC sets the LCD monitor to Remote Control Pass through mode, the LCD shall send a three bytes
packet (followed by “CR”) in response to RCU button activation. Note, that in this mode the RCU shall
have no effect on the monitor function. For example: “+Volume” will not change the volume in the
LCD but only sends “+Volume” code to PC over the RS232 port.
