There are several things to keep in mind when setting up zoned imaging:
 You are not required to enable the zones in sequence. For example, you can enable zones 2,
4, and 6 and not enable zones 1, 3, and 5.
 At least one zone must be enabled.
 Using binning effectively reduces the resolution of the camera’s imaging sensor.
As a consequence, if binning is enabled, the positions and the sizes of the set stacked zones
are automatically adapted to the applied binning factors as follows: The stacked zones
parameter values are divided by the corresponding binning factors (vertical and/or horizontal
binning factor).
If the stacked zone parameter values are not evenly divisible by the corresponding binning
factor, the parameter values are automatically rounded down to the nearest whole number.
Example for zone 1:
 You do not need to order the zones from top to bottom on the sensor. For example, you could
place zone 1 near the bottom of the sensor, zone 3 near the top, and zone 2 in the middle.
But note that the camera always reads out and transmits the zones starting from the top
of the sensor and going to the bottom, regardless of how the zone numbers are ordered.
So the lines in the transmitted images will always be ordered from top to bottom in
relation to the sensor.
 The zones can be set so that they overlap. When this happens, the camera will internally
transform the overlapped zones into a single large zone that will be read out and transmitted
as if it were simply a single large zone. (The lines included in the overlapping area will only be
read out and transmitted once.)
When stacked zone imaging is enabled, the following parameters becom read only:
 Offset Y: parameter indicates the Y offset for the zone nearest to the top of the sensor.
 Height: parameter indicates the total height of the image that will be transmitted from the
camera (i.e., the sum of the heights of all zones).
