Basler racer Camera Link 45
6.1.2 Line Start with Trigger Mode = On
When Trigger Mode is set to on, you must select a source signal for the line start trigger. Trigger
Source specifies the source signal. The available selections for Trigger Source are:
Software - When the line start trigger source is set to software, the user triggers line start by
issuing a TriggerSoftware command to the camera from the host PC. Each time a
TriggerSoftware command is received by the camera, the line start trigger will become valid. It
will become invalid during line acquisition and will become valid again when the next
TriggerSoftware command is received and when the camera is ready again for a new line
acquisition.
CC1 - When the source signal is set to CC1, you apply a line start trigger signal to the camera
by injecting an externally generated electrical signal (a "hardware trigger") into CC1 in the
Camera Link interface.
CC2 - When the source signal is set to CC2, you apply a line start trigger signal to the camera
by injecting an externally generated electrical signal (a "hardware trigger") into CC2 in the
Camera Link interface.
CC3 - When the source signal is set to CC3, you apply a line start trigger signal to the camera
by injecting an externally generated electrical signal (a "hardware trigger") into CC3 in the
Camera Link interface.
CC4 - When the source signal is set to CC4, you apply a line start trigger signal to the camera
by injecting an externally generated electrical signal (a "hardware trigger") into CC4 in the
Camera Link interface.
If Trigger Source is set to CC1, CC2, CC 3, or CC4, the user must also set the Trigger Activation
parameter. The available settings for the Trigger Activation parameter are:
Rising Edge - specifies that a rising edge of the source signal will start a line acquisition.
Falling Edge - specifies that a falling edge of the source signal will start a line acquisition.
For more information about using a software trigger to control line acquisition start, see
Section 6.1.4 on page 48.
Typically, a frame grabber is used to supply an electrical line start signal to CC1,
CC2, CC3, or CC4.
By default, CC1 is selected as the source signal for the line start trigger.
If the Line Start Trigger Source parameter is set to CC1, CC2, CC 3, or CC4, the
externally generated electrical signal applied to the selected input line must be
held high for a minimum period for the camera to detect a transition from low to
high and must be held low for a minimum period for the camera to detect a
transition from high to low:
The minimum period is 100 ns if the debouncer is not used.
The minimum period is equal to or larger than the debouncer value if the
debouncer is used.
