Epson Essential Panasonic Projector RS232 Commands for Effective Control

Panasonic projectors (Codes $30 to $32, $34)

Good set of current model RS232 codes: https://eww.pavc.panasonic.co.jp/projector/extranet/main/sitemap/index.html

Code $30: (Group 1): No adr, OSH mute/PON unmute, abs audio, PT-L501/701, L502/702, L511/711/712, PT-L735,PT-F200,PT-LB50/51/55/60,PT-LC55/56/75/76/80,PT-P1SDE and a lot more;

Code $31: (Group 2): No adr, OSH:1 mute/OSH:0 unmute, abs audio, PT-F100/F100NT/FW100NT,PT-F200/F200NT,PT-LB75/LB75NT,PT-LB80/LB80NT; and

Code $32: (Group 3): No adr, OSH mute/PON unmute, NO audio, PT-AE900/AX100/AX200,PT-AE2000

Note: Panasonic have used toggle mode in the past for the “shutter” or mute function, which makes it hard to know the current mute state for the two-yellow-button-mute-mode, and the MUTE key in the freeze/mute keyboard (code A). We have determined that the use of the OSH command to turn ON the mute mode and the use of the PON (Power On) to exit mute mode works OK on these (Groups 1 and 3 above). Panasonic have recently made it easier by introducing absolute shutter control by adding OSH:1 (Shutter ON) and OSH:0 (Shutter OFF) commands which give proper control. These recent ones are the Group 2 in this family.

Video3	:= 02 + 'IIS:YUV' + 03;		// COMPONENT
Video4	:= 02	+ 'IIS:HDM' + 03;	// HDMI

Channel codes are:
Computer1	:= 02 + 'ADZZ;IIS:RG2' + 03;		// DB15-VGA analog-RGB
Computer2	:= 02 + 'ADZZ;IIS:RG1' + 03;		// BNC (or DB15-VGA analog-RGB PT-L785)
Computer3	:= 02 + 'ADZZ;IIS:RG3' + 03;		// BNC analog-RGB (PT-L785) on some
Computer4	:= 02 + 'ADZZ;IIS:DVI' + 03;		// DVI-D

Any one of these codes can be set into Constant:0/Constant:1 for computer codes and Constant:2/Constant:3 for video codes. (The default is to have Computer1 (above) as the “Computer” channel and Video1 as the “Video” channel. Setting OPT1 switch ON will swap Video1 and Video2 channels, making S-Video the video default.)
