Remote Control Pass-Through Mode - ViewSonic VS17729 User Manual

Remote Control Pass-through Mode

When the PC sets the Display to Remote Control Pass through mode, the Display
shall send a 7-byte packet (followed by "CR") in response to remote control unit
(RCU) button activation. In this mode the remote control shall have no effect on
the Display function. For example: "Volume+" will not change the volume of the
Display, but instead only sends the "Volume+" code to the PC over the RS-232 port.
