Type
(Optional) Defines the polarity (active "high" or "low") of the
"Trigger" signal. Allowed values are 1 (normal polarity, active
DWORD
"high") and 0 (inverted polarity, active "low"). Default is 1 (normal
polarity, active "high").
(Optional) Defines the polarity (active "high" or "low") of the
"Illum_ON" signal. Allowed values are 1 (normal polarity, active
DWORD
"high") and 0 (inverted polarity, active "low"). Default is 1 (normal
polarity, active "high").
(Optional) Defines the polarity (active "high" or "low") of the
"Aimer" signal. Allowed values are 1 (normal polarity, active
DWORD
"high") and 0 (inverted polarity, active "low"). Default is 1 (normal
polarity, active "high").
(Optional) Defines the image sensor pixel clock frequency, in
DWORD Hz. Allowed values are 12000000 Hz and 24000000 Hz. Default
is 24000000 Hz.
(Optional) Defines the I
DWORD values are 100000 Hz (standard mode) and 400000 Hz (fast
mode). Default is 400000 Hz (fast mode).
(Optional) Defines the image integration (exposure) time, in
microseconds. Default is 8000 µs. In the snapshot mode, if
DWORD
illumination is enabled, the image integration time equals the
maximum illumination time.
(Optional) Defines the minimum illumination time for the
DWORD
snapshot mode, in microseconds. Default is 0 µs.
(Optional) Enables (value of 1) or disables (value of 0)
DWORD
illumination. Default is 1 (illumination is enabled).
(Optional) Defines the image sensor absolute gain multiplied by
DWORD 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).
(Optional) Defines order in which rows are transferred from the
image sensor: 0 is normal readout (from top to bottom) and 1 is
DWORD
reversed readout (from bottom to top). Default is 0 (reversed
order).
(Optional) Defines order in which columns are transferred from
DWORD 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).
(Optional) Defines the image width (number of columns).
DWORD
Default is 1280 columns.
(Optional) Defines the image height (number of rows).
DWORD
Default is 960 rows.
