6.5 Protect Window

There is a protect window before the sensor of ASI294 camera.
It's an AR-AR coated BK7 glass, diameter is 32mm and 2mm thick.

6.6 Analog to Digital Converter (ADC)

The ASI294 camera can records in 14bit ADC and 10bit ADC. You can image at a faster fps
rate if you choose to use 10bit ADC (high speed mode). This camera also supports ROI (region of
interest) shooting, and smaller ROI range support faster fps. You can uncheck "high speed" and
choose 8bit output on software to enable 10bit ADC output, otherwise this camera will use 14bit
ADC.
Here is the maximum speed of ASI294 running at 10bit ADC or 14bit ADC.

6.7 Binning

The ASI294 camera supports software bin2, bin3 and bin4 modes.

6.8 DDR Buffer

ASI294 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer
reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the
slow transfer speeds when the camera is used with a USB 2.0 port.
DDR memory buffer is the main difference between ASI "Cool" and "Pro" cameras.
