170 Basler ace Camera Link
 After each image is acquired, the camera checks the state of Control A and Control B:
If there has been no change in the state, the camera will take no action regarding the active
set.
If the state has changed, the camera will determine which sequence parameter set is now
being pointed to and will immediately replace the sequenceable parameter values in the
active set with the values from that sequence set.
 When the sequencer feature becomes disabled, the parameter values in the active set will
return to what they were before the feature was enabled.
Setting the State of Control A and Control B
Before using the sequencer feature, the user must assign a source signal to Control A and a source
signal to Control B. The user then sets the state of Control A and Control B by manipulating the
source signals. The source input signals available for Control A or Control B are:
 Line 1 - When the source signal for a control is set to line 1, you set the state of the control by
applying the appropriate electrical signal to the GPIO line on the camera. (This assumes that
the GPIO line on the camera has been properly set to operate as an input line.)
 CC1 - When the source signal for a control is set to CC1, you set the state of the control by
applying the appropriate electrical signal to CC1 in the Camera Link interface.
 CC2 - When the source signal for a control is set to CC2, you set the state of the control by
applying the appropriate electrical signal to CC2 in the Camera Link interface.
 CC3 - When the source signal for a control is set to CC3, you set the state of the control by
applying the appropriate electrical signal to CC3 in the Camera Link interface.
You can also set Control A or Control B to "Disabled". When a control is set to disabled, its value
will always be zero.
To assign a source signal to control:
 Use the Sequence Control Selector parameter to select either Control A or Control B.
 Use the Sequence Control Source parameter to set the source signal for the selected control
to Line 1, CC1, CC2, CC3, or to Disabled.
The disabled setting is useful if you only want to use one source signal to select between two of the
available sequence parameter sets. For example, you could set Control A to use CC1 as its source
signal and set Control B as disabled. In this case, you could point to sequence parameter set 0 or
sequence parameter set 1 by simply using CC1 to set the state of Control A.
When the sequencer feature is enabled, the values of the sequenceable
parameters in the active set cannot be accurately read using the pylon API or
direct register access. We recommend that you do not attempt to read or change
any of the sequenceable parameters when the sequencer feature is enabled.
