External Trigger Signal
**|
---|---
| PINS| Description
FSIN +| 3.3v-5v External Trigger Input
FSIN –| External Ground GND
Reference Circuit **
For example, VDC = 12V, Vf = 1.25V 
And there is a resistor on board(R4 = 200Ω), So the R_add =
R1 – R4 = 537.5 – 200 = 337.5Ω
STROBE Signal
| | PINS| Description
---|---
STROBE +| Sensor STROB+
STROBE –|
Reference Circuit
On-board TLP281 optocoupler isolation, Notice the max collector current is 50mA.
So If the current required to drive the Flash LED is no more than 50mA The
value of series resistor:
R1 = ( VCC- Vf – VCE ) / If
VCC: system Voltage
Vf: Forward voltage of Flash LED for current Icc
VCE: Collection Emitter voltage, typical:0.1V
If the current required to drive the flash exceeds 50mA, then it is required
to drive it with the help of LED driver circuit, and LED driver circuit can be
controlled by using the strobe output pin.

External Trigger Model
The external trigger mode is to accepts the external input signal to trigger the image output. When the rising edge of the external trigger signal coming, it can output an image. Therefore, it is very suitable for capturing high- speed moving objects. In addition, the sensor enables the sleep state will greatly reduce the power consumption.
Enable Trigger Model
We set UVC Parameters “Focus” as the trigger Model Enable options.
Open AMCAP.EXE，Choose “USB Camera” from “Devices”
From “Options” Choose “Video Capture Filter”
From “Camera Control” Find “Focus”, uncheck to enable it.
You can see the preview stop and enter
Adjust exposure Manually
- This is necessary for fast move object.
- There is a switch behind the Exposure slider in the Camera Control. Select it to start manual exposure mode.
Hardware Connection And Script
Our sample use for raspberry pi, more information please refer to chapter
2.3,We use Raspberry PI GPIO 23 generate 3.3V pulse signal.Connect Raspberry
PI GPIO23 to FSIN+, GND To FSIN-,Run command to start sudo ./gpio-sysfs
Strobe Connection
When the image is output, a flash signal output from S can drive flash to
enhance exposure. The stroboscopic signal of the sensor can set the light
point or time parameter. However, it can only output a fixed strobe signal
because of a fixed UVC Camera configuration.
