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.)
•OPT7 handshake mode and power on panel connection blink codes available (not MP722/MP723/MP771/SP870);
•Source scan must be turned off using normal on-screen menu options;
•RS232 communications must be enabled and baud rate set to 19200 in the secret factory setup menu. We have been
requested by BenQ not to include these instructions in a general manual like this: Please contact JED at:
[e-mail] for details.
•Freeze and mute are toggle mode only in these projectors, so 2-yellow-button mute mode is NOT supported (is in
MP722/MP723/MP771/SP870 as this has mute state read-back. Set T461 audio and OPT7 to use this);
•Audio functions are limited to one audio input and no output. Use a T461 if audio control is needed.

Note: MP722/MP723/MP771/SP870: These projectors have a nasty hang-up habit, where coms just stops and
only recovery is a 240v power cycle (i.e. at the power point or by pulling the power plug. Until BenQ fix this, DO
NOT INSTALL IT POWERED FROM A CEILING POWER POINT. Instruct the user on how to “power cycle”
the projector if it stops communicating.

Epson X5, X5E (etc) IR controlled projectors (Code A0 hex)
This family uses InfraRed communications with the projector via a stick-on “bug” IR transmitter placed over the IR
window on the back of the projector. It simulates the IR codes sent by the hand-held remote control, and unfortunately
the functions are limited by the projector’s lack of absolute command codes in the IR sequences. Thus there are no
absolute commands for “Video”, “Computer 1”, etc: rather the keyboard (Code 1) has a green button marked “Source /
On” which sends the “Power” command to the projector once, but does not send a “Set Source” command automatically
after warm-up. The red LED comes on immediately on power up with no flashes, and the green LED flashes during
warmup and glows continuously in the ON state. Pressing the OFF button sends the “POWER” IR message twice and
the red LED blinks during the cool-down time, then glows steadily.
The projector will start on the same source channel it was displaying when switched OFF. Pressing the “Source / On”
button again (after warm-up) will index the projector through available sources, but it will only stop on a source if a
valid input is being fed into that input when the projector is looking at that channel. If there is no input at that
point, it will not change to it, but just put up a message screen. If a valid signal is then applied, the “Source / On” button
will need to be pressed again to get it to lock onto the new source.
Models which run with this set of IR commands and IR modulation frequency of 38Khz are: EMP 740/745/737/732,
EMP765/760/755/750/X3/ S3/S4. This family of projectors all use Device-code 8355h and use “NEC” format.
User’s manuals are at: http://tech.epson.com.au/downloads/index.asp?select=7&sCategory=
A new keyboard layout has been designed for this IR mode operation, designated “Code 1”. It provides incremental
volume Up/Down keys, and the current volume level is shown on the projected image for a few seconds. The red and
green LEDs follow the current state of the projector, but if the projector gets out of step with the controller (eg by the
projector being ON when the red OFF led is showing), pressing the OFF button once (in the projector OFF state) will
send the “POWER” IR message twice (with a 1-second separation) which will get things back into step (both OFF).
Because there is no feedback serial path to the controller, OPT7 status read-back is not possible.
There is only one audio input for this projector. Operation with the T461 audio mixer (OPT7) is NOT possible, as there
is no way the controller knows which video source is in use, to command the T461 audio source switching to follow
video source.
(Freeze and mute are not supported at this stage. Two-button-mute mode is not supported either.)
Wiring
The IR transmitting bug is wired to the IR output socket J2 with the shield of the cable connected to the ground pin and
the centre conductor to the “+IR” pin. The signal is current limited (24mA pulses), so no series resistors are needed in
the cable.
As the IR bug wire is only 2M long it will usually be extended, and CAT5 cable is OK for this, but it must be via its own
twisted pair (colour plus colour-with-white). (We have successfully tested this with 50M of CAT5E cable.)
If the CAT5 connector and cable is used runs from CAT5 connector J6, the IR signal runs via a twisted pair of wires via
this cable, but link L1 must be moved from Tx (it’s position in RS232 mode) to IR (as needed for IR mode).

Hitachi projectors (Code 44 hex, single audio control, Code 45, “by channel” audio)
This family has a compact set of “BE EF” hex commands consistent across the models. Two code groups are provided:
Code 44 is used when there is an audio in for typically each RGB channel but one audio shared by all video inputs.
There is only one pair of commands for audio Inc/Dec and the level of all channels is controlled by this one pair of
commands. So if a level has been dropped for a RGB channel, the audio level is down for the Video input and needs to
be manually adjusted up. These are typically many older models (excluding 3-byte code: CP-X935 to X970.)
Also supported by code 44 are: 3M-MP8746/MP8747/MP8775, 3M-X45, 3M-X55, 3M-X75, 3M-X70, 3M-X80,
ELMO EDP-S10, VIEWSONIC PJ510/PJ853/PJ656/PJ552/PJ562/PJ750/PJ862/PJ1165/PJ1172/PJ1065, also
InfocusLP800 (Hitachi PJ-TX10 does have Code 44 audio.)
Code 45 is used when there are a number of audio inputs (2, 3 or 4) but these are
unallocated to a video channel. These must be manually allocated using the
projector menu system to suit the audio sources, cables and connectors on site, but
any audio input can typically be allocated to any video/RGB input. Audio channels
can be shared or a channel set to have no audio. A typical menu sequence is to go to:
Menu -> Advanced menu -> Audio -> Audio, which gives a table of (a variable number
of) channel names down the left column, audio inputs by number across the top, and a
matrix of buttons which allows one allocation button or an OFF button to be selected
per channel. Use the “down” button to select a channel, and the “left” or “right” buttons
to move the “dot” to select that channel’s audio. Move to the “quit” position to save and use the “left” to exit the menu.
Typical Code 45 models are: CP-X2, CP-X6, CP-X200, CP-X205, CP-X251, CP-X253, CP-X245, CP-X255, CP-X256,
CP-X260, CP-X265, CP-X268, CP-X300, , CP-X305, CP-X308, CP-X400, CP-X417, CP-X505, CP-X600, CP-X605,

LG LCD/Plasma display/TV (Code 18, 19, 1A and 1B hex)
In the back of each “Owner’s manual” is a list of “input select” codes … examine this table to determine the family.
There are over a 100 different displays in the “kb” LG family, and codes 18 and 19 cover the “kb” codes group (see the
manuals). There are several allocations used, but all use numbers in the 6 … 9 range for RGB analog computer, so all
these are drivable by the code, some may need manual (i.e. at setup time) allocation to constants 0 … 3. AV1/2 code can
vary too, but usually in the 0 … 5 range. Devices are, LCD TV 32/37/42/47/52 LB9/LC7/LC2, and plasma TV 42/50/60
PB2/4/PC5/PY3. Choice of codes 18 or 19 determines TV type, Analog or Digital.
The newer “xb” family, with codes 1A and 1B, cover the LG3, LG5, LG6 and LG7 family and use a single hex byte
after the ASCII select string, with the top 4 bits (5x, 9x, 2x, 4x) selecting an input type (AV, Component, etc) and the
low 4 bits the input number (x0 or x1). Choice of codes 1A or 1B determines TV type, Analog or Digital.
(Another, older, group uses an “i” as a leading character; these are NOT drivable with the Code 18/19/1A/1B driver.)

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:

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.
Channel codes are:
Computer1 := 02 + 'IIS:RG1' + 03; // RGB 1 VGA analog-RGB

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.)
•Power on panel connection blink codes are provided, but OPT7 handshake mode is NOT;
•Auto Pixel Align is NOT available;

RS232 connections to (all) Plus projectors
U2 and U4 use a short cable with a 9-pin-D9 female one end and a 4-pin USB-style on the other. This cable is supplied
by PLUS, and the hole to plug it in is very small, on the rear terminal panel covered with a stick-on silver plastic film.
U5 has a standard D9 male connector on the rear. U7 has 9-pin mini-DIN. Connections are the same for all four ranges.

Baud rate change
This family of projectors can be operated at 115,200 baud or 19,200 baud. As shipped from Plus, communications is at
115,200 baud, and must be set using a PC to 19,200 for use with a T440. Switch to 19,200 as follows:
Connect to a PC via a straight-though serial cable and run HyperTerminal, setting it up to run at 115,200 baud, 8 bit
data, 1 start, 1 stop, no parity, no hardware handshake (8N1). (Unless you have enabled “local echo”, you will not see
the characters as you type them. You can enable echo by going to File->Properties->Settings->ASCII Setup and
ticking Echo typed characters locally.) HyperTerminal is found under Accessories in the Windows system.
Verify communications by typing #QS(CR)(LF) (The “QS” must be upper case. The CR and LF must follow. Send a
CR with the ENTER key, and send the LF by holding down CTRL and pressing ENTER.) The projector should reply
with its status, eg #QS2 if OFF, and #QS6 if warmed up and running. If, OFF, the projector can be turned ON with the
#P1(CR)(LF) command. (The character after the Pis a numeric 1.)
Now set it to 19,200 baud by sending a command #CL(CR)(LF) from a PC running HyperTerminal at 115,200 baud. (It
will switch immediately, so the reply will be gibberish.)
Now terminate the HyperTerminal session at 115,200 baud and restart it at 19200 baud, (8N1, no handshake, local echo
enabled). Type #QS(CR)(LF) and verify status reply at 19,200 baud. A #P0(CR)(LF) command powers down the U5.
(The character after the Pis a numeric 0.) (The U5 can be reset to 115,200 baud with a #CH(CR)(LF) command.)
The baud rate is held in projector non-volatile memory, so the baud rate setting to 19,200 need be done only once.
(These commands are in Release N of the PLUS manual. Make sure the projector software is up-to-date).
