5 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.
