Serial Software Trigger: Send the next trigger immediately after receiving the last frame of image that
acquired in this trigger.
When the Multi Gray Control mode is set to 2Frame or 4Frame mode, the software will send a trigger
command immediately after receiving the last frame of image, and the camera will not respond to this
trigger command, that is, the trigger will be lost. It is necessary to delay more than 20ms before sending
the next software trigger command. So send Software Trigger command in timer is recommended.
3)
In send trigger command in timer mode, the trigger frequency determined method is as follows:
a)
Use the demo program to open the device, configure the Multi Gray Control parameters and set it to
the required mode (2Frame or 4Frame).
b)
Set <TriggerMode> to "ON".
c)
View camera properties <CurrentAcquisitionFrameRate>.
d)
When the Multi Gray Control is set to 2Frame mode, if the value of <CurrentAcquisitionFrameRate>
is 31.0Hz, then the maximum trigger frequency is 31.0 / 2 = 15.5 Hz.
e)
When the Multi Gray Control is set to 4Frame mode, if the value of <CurrentAcquisitionFrameRate>
is 44.0Hz, then the maximum trigger frequency is 44.0 / 4 = 11 Hz.

Light Source Preset
1)
MER2/ME2P/ME2S Series
The MER2/ME2P/ME2S series camera supports light source preset function, and provides Off mode,
Custom mode, and four specified common color temperature light source modes. The camera provides
the corresponding white balance coefficient and color transformation coefficient in the four specified color
temperature light source modes. The function support of different models varies slightly.
Off Mode
The camera does not perform white balance and color conversion processing on the image by default.
Custom Mode
The camera does not perform white balance and color conversion processing on the image by default.
Users can perform automatic white balance, or manually input white balance coefficients, and it supports
color conversion enable control and manually input color conversion coefficients.
Daylight-6500K
When the user selects Daylight-6500K in the light source preset, the camera will perform white balance
processing on the image by default. If the external environment light source used is D65 light source, the
image will not produce color deviation.
