11.3.3. Remote Control Pass-through mode
When the PC sets the TV/DS to Remote Control Pass through mode, the TV/DS will send a 7-byte packet 

(followed by “CR＂) in response to RCU button activation. Note, that in this mode the RCU shall have no 

effect on the TV/DS function. For example: “Volume+＂ will not change the volume in the LCD but only 

sends “Volume+＂ code to PC over the RS232 port.
