Hardware Trigger Function
Hardware trigger mode is available only when the camera works at slave mode, in
slave mode the camera will wait for the hardware trigger signal on Ext_Trigger.
The EXT_Trigger signal is to driver the MOSFET, External input trigger signal voltage
should range 3.3V-20V.
You can use input pin Ext_Trigger to send a hardware trigger signal to the camera.
The hardware trigger can be used to trigger the acquisition start.
A hardware
debouncer circuit shall be considered on the EXT_Trigger line.
By default, the hardware trigger is rising edge activated, refer to below exposure
timing:

The requirement to T1 should be from 1us to 1ms.
Exposure_timing Pin Description
This pin is an output indicates the whole exposure period of the camera. The internal
circuit of this pin with a pull-up resistor 430
Ω
.The pull up voltage is 5V.
By default, the polarity is low level activated, which means a low-level signal indicates
the exposure period. Please refer to below figure:

Type B USB2.0 Connector
The camera supports Type B-USB 2.0 transmission.
