Using Control Commands
This section explains the commands that are used to control the projector from a computer.
Command Send Format
zSee the “Command List” for details about command names and settings.
zAll commands use ASCII characters and decimal format integers.
zThe projector will return a question mark (?) when it is sent a command it cannot recognize. Also, 
any command that attempts to set a value that is outside the applicable allowable range will be 
ignored.
zIf the projector is performing a process initiated by a previously sent command, a projector key 
operation, or a remote controller key operation, send of the next command must wait until the 
projector completes the previous process.
Communication

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By 
contrast, the GNU General Public License is intended to guarantee your freedom to share and change 
free software--to make sure the software is free for all its users. This General Public License applies to 
most of the Free Software Foundation’s software and to any other program whose authors commit to 
using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public 
License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses 
are designed to make sure that you have the freedom to distribute copies of free software (and charge 
for this service if you wish), that you receive source code or can get it if you want it, that you can 
change the software or use pieces of it in new free programs; and that you know you can do these 
things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to 
ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you 
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the 
recipients all the rights that you have. You must make sure that they, too, receive or can get the 
source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which 
gives you legal permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone understands that 
there is no warranty for this free software. If the software is modified by someone else and passed on, 
we want its recipients to know that what they have is not the original, so that any problems introduced 
by others will not reflect on the original authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger 
that redistributors of a free program will individually obtain patent licenses, in effect making the 
program proprietary. To prevent this, we have made it clear that any patent must be licensed for 
everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, 
DISTRIBUTION AND MODIFICATION
0.This License applies to any program or other work which contains a notice placed by the copyright 
holder saying it may be distributed under the terms of this General Public License. The “Program”, 
below, refers to any such program or work, and a “work based on the Program” means either the 
Program or any derivative work under copyright law: that is to say, a work containing the Program 
or a portion of it, either verbatim or with modifications and/or translated into another language. 
(Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is 
addressed as “you”.
Activities other than copying, distribution and modification are not covered by this License; they 
are outside its scope. The act of running the Program is not restricted, and the output from the 
Program is covered only if its contents constitute a work based on the Program (independent of 
having been made by running the Program). Whether that is true depends on what the Program 
does.
1.You may copy and distribute verbatim copies of the Program’s source code as you receive it, in 
any medium, provided that you conspicuously and appropriately publish on each copy an 
appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this 
License and to the absence of any warranty; and give any other recipients of the Program a copy of 
this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer 
warranty protection in exchange for a fee.
2.You may modify your copy or copies of the Program or any portion of it, thus forming a work based 
on the Program, and copy and distribute such modifications or work under the terms of Section 1 
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files 
and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is 
derived from the Program or any part thereof, to be licensed as a whole at no charge to all third 
parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, 
when started running for such interactive use in the most ordinary way, to print or display an 
announcement including an appropriate copyright notice and a notice that there is no warranty 
(or else, saying that you provide a warranty) and that users may redistribute the program under 
these conditions, and telling the user how to view a copy of this License. (Exception: if the 
Program itself is interactive but does not normally print such an announcement, your work 
based on the Program is not required to print an announcement.)
