Command structure

Each command is packaged in this structure:

0xFE 0x00 PREFIX CMD DATA CHK 0xFF

Start byte

(1 byte)

Device address

(1 byte)

Prefix (0..n

bytes)

Command

(1..n bytes)

Data (0..n

bytes)

Checksum

(1 byte)

Stop byte

(1 byte)

Explanation:

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

Device address is used when multiple devices are connected on the same physical connection. This is

typically used with serial connections. In case of Ethernet connections this is either ignored, or should be set

to a fixed value, depending on the protocol.

Prefix bytes: for some special commands it is possible to use prefix bytes before the actual command bytes.

It depends on the actual protocol implementation which prefixes are available and when they can be used.

Command bytes: there will be at least one byte per command. The command bytes actually tell the device

what to do.

Data bytes: this is optional and depends on the command that will be sent. See also “Data byte” chapter.

Checksum byte: this byte is used to detect errors in the transmission or reception of the command. For more

information, see the “Checksum” chapter.

IMPORTANT NOTE

Any comm 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 send: Actual mark up of the byte to send:

Byte to send Actual mark-up of

the byte to send

0x80 0x80 0x00

0xFE 0x80 0x7E

0xFF 0x80 0x7F

Data bytes

Characters: we will be using ANSI coding for characters (1 byte per character).

Strings: strings can be formatted in two ways:

o C-style format: an array of one or more characters which is terminated by a NULL character (0x00). The

position of the NULL character determines the length of the string.

Exmaple: 'f' 'o' 'o' ' ' 'b' 'a' 'r' 0x00

o Pascal-style format: an array of one or more characters. The first byte of the string indicates the length of the

string. Therefore pascal-style strings are limited to 255 characters.

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

Multi-byte values: a multi-byte value consists of more than one byte. The first byte is the Most Significant

Byte (MSB).

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

536956976.

Checksum

The checksum value for a command is calculated by doing a modulo 256 on the sum of the byet values of all

bytes between start of the command and the checksum byte

Checksum calculation

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

Acknowledgement

ACK and NACK

When a command is received, the command format and checksum should be checked. For our application, the

device address should be ignored. If there's an error in the command bytes or the checksum, the command

should be ignored.

If the command is a valid command, the receiver should answer back with an acknowledgement before starting

the processing of the command. If the command is not valid, the receiver should answer with a no acknowledge.

ACK (ACKnowledge)

Command[0] 0x00

Command[1] 0x06

An ACK is sent in these cases:

The command bytes are correct (checksum is OK)

The command and its parameters are valid

If one of these fail, an NACK will be returned.

NACK (Not ACKnowledge)

Command[0] 0x00

Command[1] 0x15

Example

Start byte 0xFE

Device

address: 0x00

Command[0] 0x00

Command[1] 0x15

Checksum 0x15

Stop byte 0xFF

Handling of no acknowldge (NACK)

When a command doesn't get acknowledged, it is up to the sender to decide what should happen with the

command: retry sending the command again or discard the command. The decision is mainly based on the type

of command and the situation it is used.

IMPORTANT NOTE

communication, an acknowledge must always be returned by the receiver for each correct and valid

receives, before processing the command and replying on the command.

edge does not count as a reply on the execution of the command.

t communication, acknowledgments are not used

Command responses

Replying commands

A lot of commands that can be send out, do not only return a ACK or NACK, but may also return a reponse or

reply. This reply will be sent after processing the command. The answer will have the same command bytes as

the request, but typically the data bytes will contain the response information. It depends on the protocol

implementation whether a command requires a reply or not. This will be defined per command in the protocol.

Example:

When requesting a projector's type, you should use the command 0x6b (projector, read type). In answer, the

projector will return a string containing the actual type of the device:

Request:

Start byte 0xFE

Device

address: 0x00

Command[0] 0x6b

Checksum 0x6b

Stop byte 0xFF

Acknowledge:

Start byte 0xFE

Device

address: 0x00

Command[0] 0x00

Command[1] 0x06

Checksum 0x06

Stop byte 0xFF

Reply:

Start byte 0xFE

Device

address: 0x00

Command[0] 0x6b

Data[0] 0x42 = 'B'

Data[1] 0x41 = 'A'

Data[2] 0x52 = 'R'

Data[3] 0x43 = 'C'

Data[4] 0x4f = 'O'

Data[5] 0x20 = ' '

Data[6] 0x46 = 'F'

Data[7] 0x4c = 'L'

Data[8] 0x4d = 'M'

Data[9] 0x20 = ' '

Data[10] 0x48 = 'H'

Data[11] 0x31 = '1'

Data[12] 0x38 = '8'

Data[13] 0x00

Checksum 0x03

Stop byte 0xFF

Handling of failing responses

When a receiver fails to return the expected response (acknowledge or reply) on a command, we need to follow

some steps to handle this failing communication.

There are 2 possible failures:

1. Communication link problems: If the sending of the commands itself doesn't work, it will be because the

communication is broken (f.i. the receiver as disconnected from the network).

2. Answer back problems: when commands can be sent out but no response is sent back, it means that the

communication link is OK but the receiver is unable to answer back.

Each type of failure needs another way of handling.

Handling communication link problems

As communication link problems will most likely have a physical reason (cable disconnected, hub down,

projector down, …), we need to notify the user and ask him for his feedback. In most cases there will be a user

intervention needed to correct this problem (connect the cable, reboot the hub, restart the projector, …).

The actual implementation of this, should be described in the specifications of the application.

Handling answer back problems

Answer back problems should be addressed in another way. When a receiver fails to answer back it might be

that it is currently too busy to answer back. The application software should implement some simple

mechanisms to avoid problems when this occurs:

1. Timeout waiting: the application should wait for a limited amount of time for an answer (f.i. max 10

seconds). This ensures that the application can react when a command doesn't get answered in time.

2. Retry waiting: if the timeout expires, we can retry waiting for the answer. By doing this, the user has the

opportunity to cancel the action. If needed, the retry can even be repeated several times.

3. Retry sending: when a command does not get answered after the timout waiting and retry waiting, the

command is considered to be lost in action and the application should send the command again.

This mechanism follows the sequence of the steps: first the timeout waiting is used, then the retry waiting and

finally the retry sending. If all of these steps fail, there might be a major problem with the receiver in in this

case we should notify the user of these problems so that he can check the status of the receiver.

All the projectors that support UDP

broadcast discovery, will answer on

the request by sending an array of

(C-language) strings. Each string is

represents a key-value pair with

specific information about the

projector that has been discovered.

Typically, following strings will be

returned:

hostname=value: the hostname

of the projector

ip-address=value: the IP

address of the projector

mac-address=value: the MAC

address of the NIC on the

projector
