Mitsubishi projector families: Codes 24 to 28 hex

In the back of some user manuals is a list of RS232 control messages.

Also, see master RS232 code list at: http://www.mitsubishi-presentations.com/customercare/projector_tools.html (There are some confusions is this site, eg the DX300 link calls up the X300, so to get the XD300/350 sheet use the XD350.)

Volume range settings determine what codes family to select: Audio is done either with an “Absolute” command, “00VL” followed by a decimal 2-digit number, eg “00VL21<CR>”, or an increment/decrement command “00r06 <CR>” and “00r07 <CR”.

For the absolute volume controlled projectors, there is a paragraph in the manual section or document called “Controlling the projector using a personal computer” called “Volume Commands”. Look in there for the volume range, eg 00 – 31 in the box after the VL command definition. Select a control code from the following table:

Volume range	Code group on hex switches	Volume range	Code group on hex switches
00-21	$24	00-60	$26
00-31	$25	00-100	$27

Note: Recently we have found some Mit. Projectors have different audio control ranges than the Mit. manual states. If you cannot get the full range, try a diff. code.

Some model types for code group 24 hex, 00-21 range:

EX10U, ES-EX100U, HC100, S/XD420U, S/XD430U, HC900/E, WD2000, WL639U, XD435U, XD400U, XD450U, XD460U, XD470U, XD480U, XD490U, XD500, XD510U, XD520U, XD2000U, XL6U

Some model types for code group 25 hex, 00-31 range:

FL7000U, S/XL4U, XL5U, SL6U, XL8U, XL9U, S/XL25U, XL30U, X200E, S/XD200U, XD300U, XD350U, X390U, X400U, SX490U, X500U, XL550U, XL650U, XL1550U, XL2550U, XL5900U, XL5950U, XL5980U/LU,

InFocus LP1200

Some model types for code group 26 hex, 00-60 range:

S/XL1U, S/XL2U, S/X50U, SA51U, X70/U, X80U

Some model types for code group 27 hex, 00-100 range:

SD105U, S/XD206U:

Some model types for code group 28 hex, no audio or inc/dec audio only range:

If there is no “Volume commands” paragraph (or no audio in the projector), use the incremental control driver selection, code $28.

No audio: HC1100, HC1500, HC3000, HC3100, HC4900, HC5000, HD1000, HD4000

Inc/dec audio: X100E, S/X120E, S/X250U, S290U, X300U

Channel codes are:
Computer1 :=	'00_r1' + 0D;
Computer2 :=	'00_r2' + 0D;
Computer3 :=	'00_d1' + 0D;
Computer4 :=	'00_d2' + 0D;
Video1 :=	'00_v1' + 0D;
Video2 :=	'00_v2' + 0D;
Video3 :=	'00_c1' + 0D;
Video4 :=	'00_d1' + 0D;
Video5 :=	'00_d2' + 0D

//RGB 1 VGA analog-RGB

//RGB 2 VGA analog, sometimes DVI analog

//DVI Analog 1

//DVI Analog 2

//Vid composite 1 or S-Video 1

//Vid composite 2 or S-Video 2

//Component

//DVI or HDMI 1

//DVI or HDMI 2

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.)
