Trigger Sources
The camera allows for four sources for triggering: external Line1 or Line2, internal (pulse
generator), and software. The minimum trigger pulse is 10 microseconds.
•
Line 1
– hardware Input Line GP Input1 (Trigger 1) is used as external source for the trigger
signal.
•
Line 2
– hardware Input Line GP Input2 (Trigger 2) is used as external source for the trigger
signal.
•
Pulse Generator
– trigger source is generated by camera's internal Pulse Generator.
•
Software
– the camera expects a computer to send a command to the camera for
generating one short trigger pulse. You can trigger the camera by clicking the GUI Software
Trigger button or by sending the GenICam Trigger Software command.
