R59770107 RS232 FOR FLM R20+ 08/03/2007 3

1. The Barco LCD/DLP Protocol Basics

1.1 Command basics

Command structure

Each comm and is packaged in this structure:

0xFE ADDR PREFIX

CMD

DATA

CHK

0xFE

Start by te (1

byte)

Device

address ( 1

byte)

Prefix (0..n

bytes)

Command

(1..n bytes)

Data (0..n

bytes)

Checksum (1

byte)

Stop by te (1

byte)

Explanation

• The s tart and stop byte are used to let te receiver know that a command is starting or has stopped.

• Device addre ss is used when multiple devices are connected on the sam e phy sical connec tion. This is typically used with serial

connections. In case of E thernet connections this is either ignored, or s hould be set to a fixed v alue, depending on the protocol.

• Prefix bytes: for some special comm ands it is possible t o use prefix bytes before the actual command bytes. It depends on the

actual protocol implem entation w hich prefixes are av ailable an d when they can be used.

• Command bytes: there will be at least one byte per comm and. The com mand bytes ac tually tell the device what to do.

• Data bytes: this is optional and depends on the command that will be sent. See also Data bytes cha pter. l Checksum by te:

this byte is used to detect er rors in t

he transmission or reception of the c omm and. For more information, see the Checksum

chapter.

Important note

Any command byte, data byte or checksum byte that equals 0x80, 0xFE or 0xFF, has to be marked up with a leading 0x80:

Byte to s end:

Actual m ark up of the byte to send:

0x80 0x80 0x00

0xFE 0x80 0x7E

0xFF 0x80 0x7F

Data bytes

• Characters: we will be using ANSI c oding for ch aracters (1 byte per character).

• Strings: strings can be formatted in two ways:

- C-style format: an array of one or mo re characters which is terminated by a NULL character (0x00). T he position of the

NULL character de termines the length of the string.

Example: ’f’ ’o’ ’o’ ’ ’ ’b’ ’a’ ’r’ 0x00

- Pascal-style format: an array of one or m ore characters. The first byte of the s tring indicates the length of the string. There-

fore pascal-style strings are limited to 255 c haracters.

Example: 0x07 ’f’ ’o’ ’o’ ’ ’ ’b’ ’a’ r’

• Multi-byte values: a multi-byte value consists of m ore than one byte. The first byte is the Most Significant B yte (MSB). Example

of a 4-byte value: 0x01 0x20 0x50 0x30 = 0x01 * 2563 + 0x20 * 2562 + 0x50 * 256 + 0x30 = 536956976.

Checksum

The checksum v alue for a command is calculated by doing a modulo 256 on the sum of the byet values of all bytes between s tart of

the command and the checksum byte

Checksum calculation:

Checksum byte = (Device address + Prefix bytes + Command bytes + Data bytes) mod 256
