For example, the second triggersource for trigger mode 1 is called
externalTrigger1-mode1. To use mode 3, the triggersource is
internalTrigger-mode3.
Note: Toolbox versions before R2010a supported DCAM trigger mode 0 with the first
available triggersource as externalTrigger. The existing externalTrigger
property will be maintained so to prevent backward compatibility issues. In
addition, in order to preserve symmetry with the new functionality, triggersource
externalTrigger0-mode0, which is synonymous, will also be supported. The new
trigger modes do not work before R2010a.
Usage Notes
If a trigger mode has multiple trigger sources (modes 0, 1, 2, 4, and 5), then
triggersource has a digit indicating the corresponding camera source, even if only one
camera source is available. For example, if the camera has only a single triggersource
available, the toolbox reports the triggersource name as externalTrigger0-modeX.
If the trigger mode does not have multiple sources (mode 3), then no source digit appears
in the name (i.e, internalTriggerMode3 instead of internalTriggerMode3-
Source0).
The DCAM adaptor includes a TriggerParameter property that is passed to the
camera when you set trigger configurations. The TriggerParameter property is
validated when you call START after selecting a hardware trigger mode.
If the selected trigger mode prohibits multiple frames per trigger, then an error appears
when you call START without setting FramesPerTrigger to 1.
