ViewSonic IFP6552-2F - Remote Control Pass-Through Mode

145
Remote Control Pass-through Mode
When the PC sets the Display to Remote Control Pass through mode, the Display
will send a 7-byte packet (followed by “CR”) in response to remote control unit
(RCU) buon acvaon. In this mode the remote control shall have no eect on
the Display funcon. 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.
