communication protocol

Communication protocol summary

Start byte \xfe

Projector address

Command byte(s)

Data bytes(OPTIONAL)

Checksum byte

Stop byte \xff

Start byte

The "start byte" informs the projector (in case of

transmission) or the 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. 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) :

Wheather the command bytes are followed by one or more

data bytes depends on the contents of the command bytes.

(Some commands are not followed by data bytes at all !)

BARCO Serial Communications User Manual 13

communication protocol

Checksum byte :

The "checksum byte" 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) 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.

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

Communication settings summary

Baud rate see Owner's Manual

Data bits 8

Parity no

Stop bits 1

Baud Rate :

Defines the speed of the data transfer.

The baud rate can be set, depending on the type of

projector, using the dip switches on the processor board of

the projector or 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.

hardware

Connector labelled "RS232 IN" :

This female D9-pin connector is used to connect the

projector with the computer.

Connector labelled "RS232 OUT" :

This male D9-pin connector is used to drive the next

projector in a chain.

Pin-out :

The pin-out is the 'standard' PC-AT convention, which is :

BARCO Serial Communications User Manual 18

syntax

Characters :

In this manual, all characters are expressed using the C-

language syntax :

decimal values ddd ddd = 0..255

hexadecimal values \xhh hh = 00..ff

Negative values/numbers :

The 2s complement number system is used 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.

Example : "hello world"

length \x0b

'h' \x68

'e' \x65

'l' \x6c

'o' \x6f

' ' \x20

'w' \x77

'o' \x6f

'r' \x72

'l' \x6c

'd' \x64

BARCO Serial Communications User Manual 19

syntax

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, the length of a C-language string is

determined by the position of the NULL character.

Example : "hello world"

'h' \x68

'e' \x65

'l' \x6c

'o' \x6f

' ' \x20

'w' \x77

'o' \x6f

'r' \x72

'l' \x6c

'd' \x64

NULL \x00

BARCO Serial Communications User Manual 20

syntax

Filename

A filename is specified as a C-language string. This string

has to follow some rules : Filename

0123456789101112

xxxxxxxx. yzzNULL

length string = 12

x = character of the base name (= 8 characters)

'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j'

'k' 'l' 'm' 'n' 'o' 'p' 'q' 'r' 's' 't'

'u' 'v' 'w' 'x' 'y' 'z' '0' '1' '2' '3'

'4' '5' '6' '7' '8' '9' '_' '-' ' '

y = kind of file (= 1 character)

's' standard file

predefined file stored in read-only memory

'c' custom file

file created by the user and stored in non-volatile read-

write memory

z = file index (= 2 characters)

'0' '1' '2' '3' '4' '5' '6' '7' '8' '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 loaded when no signal

is applied).

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 (?) wildcard character for x, y and z. This wildcard

character can represent any possible character on that

location.

Examples : "ntsc .c01", "svga_60v.s?7", "????????.???"
