Specifying the Trigger Type
6-19
If the camera supports only trigger mode 0 with source 0, then the original functionality
of having only the externalTrigger triggersource is supported.
Trigger modes 14 and 15 are vendor-specific and are assumed to be external triggers and
have no restrictions on any settings. You must validate any settings you use.
The following sections detail the trigger modes.
Trigger Mode 0
This is the only trigger mode supported before R2010a. When a trigger is received, a
frame is acquired. You can acquire multiple frames per trigger by switching the camera
for hardware triggered mode to free running mode when a triggered frame is acquired.
No parameter is required.
The camera starts the integration of the incoming light from the external trigger input
falling edge.
Trigger Mode 1
