Appendix A: Camera control protocol

omman

Notation of the general syntax:

– All separate entities in a message are represented between curly brackets, e.g.

{CRC}

– Literal strings are between quotes, e.g. 'P'

– Logical entities are neither between brackets nor quotes, e.g. Mic.-No. (microphone number)

– A logical entity will also contain a number between brackets. This number states how many characters the entity exists of, e.g.

(4)

– If the subtext

is attached to the entity between curly brackets, this means that one or more occurrences of this entity may occur
