Start byte
Thestart byte informs the projector (in case of transmission) orthe computer
(in case of reception) that a new data transfer will take place.
Projector address
The projector address defines the address of the projector the computer
wants to talk to (in case of transmission) or the address of the projector that
answers (in case of reception).
The maximum number of projectors that can be addressed by one computer
is 256.
Command byte(s)
There is at least one command byte to define the action to be performed.
Commandsthatare not often used or complex commands can take more than
one byte.
All command bytes that are sent by the computer to get information out of the
projector are repeated in the answer-data-transfer of the projector.
Data bytes(OPTIONAL)
Wheatherthecommand bytes are followedbyoneor more data bytes depends
on the contents of the command bytes.
(Some commands are not followed by data bytes at all !)

Checksum byte
Thechecksumbyte is used to detect errors during transmission or reception.
Formula :
Checksum byte
= (Projector address + Command bytes + Data bytes) modulo 256
Stop byte
Thestop byte informs the projector (in case of transmission) orthe computer
(in case of reception) that the data transfer is complete and that the
interpretation of the command and data bytes can start.
Any command byte, data byte or checksum byte that equals \x80, \xfe
or \xff has to be converted !
Transmission :
- Instead of \x80, send \x80 followed by \x00.
- Instead of \xfe, send \x80 followed by \x7e.
- Instead of \xff, send \x80 followed by \x7f.
Reception :
- Replace \x80 followed by \x00 with \x80.
- Replace \x80 followed by \x7e with \xfe.
- Replace \x80 followed by \x7f with \xff..

Communication settings summary
Baud rate see baudrate table
Data bits 8
Parity no
Stop bits 1
Baud Rate
Defines the speed of the data transfer.
The baud rate can be set using the dip switches on the processor board of the
projector. Beforeopeningthe projector*, insure the projector is powered down
!!!
Check the baud rate table to set up the communication speed.
Consult the owners manual of the projector to change the baud rate setting.
*In some projectors, the Baud Rate must be set using the menu structure (see Owner's manual
of the projector).
Data Bits
Eight data bits are used for each character of the data transfer.
Parity
There is NO parity bit used to perform error checking.
Stop Bits
One stop bit is used to define the end of a character.

C-language string:
A C-language string consists of one or more
characters.
The last character of the string is always the
NULL(\x00)character. Therefore,thelength
of a C-language string is determined by the
position of the NULL character.
Example : hello world
A pascal-language string consists of one
