Value 

Type 

Description 

POLARITY_TRIGGER 

DWORD 

(Optional) Defines the polarity (active “high” or “low”) of the 
“Trigger” signal. Allowed values are 1 (normal polarity, active 
“high”) and 0 (inverted polarity, active “low”). Default is 1 (normal 
polarity, active “high”). 

POLARITY_ILLUM 

DWORD 

(Optional) Defines the polarity (active “high” or “low”) of the 
“Illum_ON” signal. Allowed values are 1 (normal polarity, active 
“high”) and 0 (inverted polarity, active “low”). Default is 1 (normal 
polarity, active “high”). 

POLARITY_AIMER 

DWORD 

(Optional) Defines the polarity (active “high” or “low”) of the 
“Aimer” signal. Allowed values are 1 (normal polarity, active 
“high”) and 0 (inverted polarity, active “low”). Default is 1 (normal 
polarity, active “high”). 

PixelClock 

DWORD 

(Optional) Defines the image sensor pixel clock frequency, in 
Hz. Allowed values are 

12000000

 Hz and 

24000000

 Hz. Default 

is 

24000000

 Hz. 

I2CBusClock 

DWORD 

(Optional) Defines the I

2

C bus transfer rate, in Hz. Allowed 

values are 100000 Hz (standard mode) and 400000 Hz (fast 
mode). Default is 400000 Hz (fast mode). 

IntegrationTime 

DWORD 

(Optional) Defines the image integration (exposure) time, in 
microseconds. Default is 8000 µs. In the snapshot mode, if 
illumination is enabled, the image integration time equals the 
maximum illumination time. 

MinFlashTime 

DWORD 

(Optional) Defines the minimum illumination time for the 
snapshot mode, in microseconds. Default is 0 µs. 

IllumControl 

DWORD 

(Optional) Enables (value of 1) or disables (value of 0) 
illumination. Default is 1 (illumination is enabled). 

Gain1000 

DWORD 

(Optional) Defines the image sensor absolute gain multiplied by 
1000. It ranges from 

1000

 (Gain = 1 or 0 dB) to 

16000

 (Gain = 

16 or 24.08 dB). Default is 

1000

 (Gain = 1 or 0 dB).  

ReverseRows 

DWORD 

(Optional) Defines order in which rows are transferred from the 
image sensor: 

0

 is normal readout (from top to bottom) and 

1

 is 

reversed readout (from bottom to top). Default is 

0

 (reversed 

order). 

ReverseCols 

DWORD 

(Optional) Defines order in which columns are transferred from 
the image sensor: 

0

 is normal order (from left to right) and 

1

 is 

reversed order (from right to left). Default is 

0

 (reversed order). 

ImgWidth 

DWORD 

(Optional) Defines the image width (number of columns).  
Default is 1280 columns. 

ImgHeight 

DWORD 

(Optional) Defines the image height (number of rows).  
Default is 960 rows.
