2.5.8 Flash Trigger Signal
A400k cameras output a flash trigger signal that can be used to trigger a flash exposure. The flash
trigger output connector is described in Section
.
The flash trigger signal can be programmed to operate in five different modes:
• The signal is always
low
, that is, deactivated.
• The signal is always
high
.
• The signal is
high
as long as the sensor’s flash window is open, that is, all pixel lines are
exposed to light. The signal goes high when exposure starts in the last pixel line of the area
of interest and the signal goes low when exposure ends in the first pixel line.
• The signal is
low
as long as the sensor’s flash window is open, that is, all pixel lines are
exposed to light. The signal goes low when exposure starts in the last pixel line of the area of
interest and the signal goes high when exposure ends in the first pixel line.
• The signal is tied to the ExFlash input signal provided by the frame grabber and the signal is
high
while the ExFlash signal from the frame grabber is high.
• The signal is tied to the ExFlash input signal provided by the frame grabber and the signal is
low
while the ExFlash signal from the frame grabber is high.
In addition, four switching options are programmable:
• TTL
• Open collector or Low Side Switch, 5 V max
• High Side Switch 5 V
• High Impedance
The switching options are explained on page
2.5.8.1 Setting the Flash Trigger Signal
You can set the flash trigger signal using either the Camera Configuration Tool Plus (CCT+) or
binary commands.
With the CCT+
With the CCT+ (see Section
), you use the settings in the Flash Trigger parameter group.
By Setting CSRs
You can program the flash trigger signal by writing a value to the Mode field of the Flash Trigger
Output Mode CSR and Flash Trigger Switching Mode CSR (see page
for an explanation of CSRs. See Section
for an explanation of using read/
write commands.
L
If the exposure time setting on the camera is lower than the minimum flash exposure
required (see page
), no flash trigger signal will be output.
