1. SERIAL COMMUNICATIONS BASICS
Overview
• Communication Protocol
• Data words
• Communication settings
• Hardware
• Syntax
• Serial comms commands
1.1 Communication Protocol
Communication protocol summary
Like every communication method the serial communication uses a particular protocol (ANSI) which must be respected in order to
allow communication to take place, following table gives a summary of the predefined communication terms.
Start byte \xfe
Projector address
Command byte(s)
Data bytes
Checksum byte
Stop byte \xff
1
ANSI
American National standards Institute
Start byte
The “Start byte” informs the projec
take place
tor (in case of transmission) or the computer (in case of reception) that a new data transfer will
Projector address
The “projector address” defines the address of the computer the projector 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. Commands that are 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)
Whether the command byt
Data which contains more than one byte is called a word and can also be signed or unsigned.see "Data words", page 6
1. optional
R5976884 RLM SERIES 04/04/2006 5
es are followed by one or more data bytes depends on the contents of the command bytes.
1. Serial communications Basics
Some com mands do not require a data field(s)
Checksum byte
The “Checksum byte” is used to detect errors during transmission or reception
Checksum byte = (projectoraddress + command bytes + Data bytes) Modulo \x100
Stop byte
The “Stop byte” informs the projector (in case of transmission) or the computer (in case of reception) that the data transfer is complete
and that the interpretation of the command and data bytes can start.
Acknowledge (ACK)
If the communication link and if the sent commands can be interpreted by the projector an “ACK” command is sent back. In case the
commands cannot be interpreted a “NACK” command is sent back.
End of process (EOP)
When the end of process command is activated, an EOP is send after the ACK command to signify the completion of the process.
for more information about this, see t he EOP command.
Note
Any command byte, data byte or checksum byte that equals \x80, \xfe, \xff hastobeconverted!
1. 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
2. Reception
- replace \x80 followed by \x00 with \x80
- replace \x80 followed by \x7e with \xfe
- replace \x80 followed by \x7f with \xff
1.2 Data words
msb
The most significant byte, is the byte with the greatest weight (value).
lsb
The less significant byte, is the byte with the smallest weight (value).
Description
A word contains more than one byte, the first byte is the msb, the last byte is the lsb.
Examples of data words
• The projector runtime parameter is described using an unsig
the runtime in seconds.
How to calculate the value of a word ?
Lets take the example of a double word returned by the “projector runtime, read” commando.
6
ned double word where 2 bytes (msb ...lsb) represent the value of
R5976884 RLM SERIES 04/04/2006
returned data = Data[0]....Data[3]
3
value = Data[0]*256
+ Data[1]*2562+ Data[2]*256 + Data[3].
1.3 Communication settings
Baud rate
Defines the speed of the data transfer. The baud rate can be set using the menu structure.
Consult the Owner’s manual of the projector on how to change the baud rate setting.
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.

1.5 Syntax
Characters
In this manual, all characters are expressed using the C- language syntax:
1. Serial communications Basics
decimal values ddd
hexadecimal values \xhh
The characters that can be used are
For text fields: "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+-/&@#_:;abcdefghijklmnop qrstuvwxyz”
For filenames: "?*ABCDEFGHIJK LMNOPQRSTUV
WXYZabcdefghijklmnopqrstuvwxyz0123456789_ -"

3
Negative values /numbers
The 2s complement number system is use
d to express negative numbers
Pascal- language string
A Pascal-language string consists of one or more characters. The first character of the string contains the length of the string.
Therefore, a Pascal-language string is limited to 255 characters.

C-language string
A C-language string consists of one or more characters. The last character of the string is always the NULL character \x00.Therefore, the length of a C-language string is determined by the position of the NULL character..

Filename
A filename is specified as a C-language string. This string has to follow some rules:
x x x x x x x x . y z z
1. length string = 12
2. x = character of the base name formed by max 8 characters
3. y = kind of file (= 1 character)
NULL
’s’
’c’
4. z = file index (= 2 characters: 0..9)
zz specifies the location in memory where the file is stored.
- for standard files: zz = 00...maximum standard files
- for custom files: zz = 00...63 where 00 is reserved for the file ’none .c00’ (file which is loaded when no signal is applied)
5. yzz is a unique combination. In other words, no two files can exist with the same extension yzz.
To specify more than one file you can use the question mark (?) and (*) wild card character for x, y and z (or
any other character).
?: This wildcard character can represent any possible character on a particular location.
* : This wildcard character can represent any possible character(s) following the wildcard’s position in the
string.
