The objective of silent mode is intended for professional presentation so that the OSD will not pop up to interfere with presentation. 2 To further enhance the viewing experience of the audience ­ more precise commands are added to minimize the disruption during a source change. Furthermore, to avoid confusion with old RS232 commands and possible software maintenance problem the silent OSD are implemented using new RS232 commands. The side benefit of this implementation is user choose silent OSD or non-silent OSD just by invoking different RS232 commands IR 030 IR 031 IR 032n source lock on source lock off source select n=1 is DVI-D n=2 is DVI-RGB (*1) n=3 is DVI-YPbPr (*1) n=4 is D-sub RGB n=5 is D-sub YPbPr (include 480i, 480p, 720p, 1080i, 576i, 576p) n=6 is D-sub SCART n=7 is RCA YPbPr (include 480i, 480p, 720p 1080i, 576i, 576p)(*2) n=8 is composite n=9 is S-video aspect ratio n=1 is 4:3 n=2 is 16:9 n=3 is window = 4:3 inside 16:9 n=4 is letterbox nn= 00-99, 99 is the brightest IR 033n IR 034nn brightness IR 035nn contrast nn=00-99, 99 is highest contrast IR 036nn volume nn=00-99, 99 is loudest IR 037nn zoom nn=0-31, 31 is maximum zoom IR 038n color temperature n=1 is low n=2 is medium n=3 is high New read commands (not related to silent mode) ID ? returns ID x x= any unique ID such as serial no.
