Invalid configurations of the CID command are ignored and
the data discarded. Any signs in the value field are ignored.
The data fields in this command must contain byte-aligned
binary data, not ASCII data.
This command has two forms: the six-byte short form
described below, and the long form consisting of these six
bytes, plus additional information specific to the color space.
Common 6-Byte
Header
The short and long forms of the CID command use a
common 6-byte header, regardless of which color space is
specified. The header data fields, whose meaning may vary
according to the color spaces, are present in all color space
specifications. The short form and long form of the CID
command are explained separately in the following pages.
