Chunk data
Chunk data are tagged blocks of data, that are sent together with the image data. In
Ranger3, chunk data are used to add encoder data to the image data. Each buffer con‐
tains, in addition to the image data, a chunk of meta data. The following meta data are
available for each buffer:
•
The value of the encoder counter for each line in the buffer.
•
The timestamp for each line in the buffer.
•
The height of the buffer.
•
The width of the buffer.

Features
The features that are used for Ranger3 are listed in the following sections (see
for a definition of a feature). Most of the features comply with GenI‐
Cam™ SFNC. There are also some custom features that are described in separate
tables.
The "Type" column defines the data type for a feature. GenICam defines a number of
interface classes for SFNC features, where each interface class corresponds to a data
type. For example, the interface class "IBoolean" corresponds to the data type
"boolean".
The "Visibility" column defines which user that sees a feature in the parameter editor,
see "Parameter editor", page 47
. Note that the visibility level of some standard fea‐
tures has been adjusted compared to the recommended setting.
The "Access" column defines if the feature is readable ("R"), writeable ("W"), or both
("RW"). "R(W)" means that for some selector values the feature is both read- and write‐
able, but for other selector values it is just readable. In some cases, the read- and write‐
ability of a certain parameter depends on the model and version of the device.
For further information, including detailed descriptions of the standard parameters, see
www.emva.org/standards-technology/genicam/
NOTE
There are parameter dependencies both within and between the feature groups, which
means that changing the value of one parameter might also change the value of others.
Examples:
•
The maximum
AcquisitionLineRate
value depends on the
Height
value (a larger num‐
ber of rows gives a lower maximum speed).
•
The maximum
ExposureTime
value depends on the
AcquisitionLineRate
"Exposure time and measurement speed", page 27
