Why there are cameras whose values writable to PixelFormat register are different from the other same model cameras?（No.1518）
Bayer type PixelFormat (PXL_FMT_BayerGR8, PXL_FMT_BayerRG8, PXL_FMT_BayerGB8, PXL_FMT_BayerBG8, and so on) writable to PixelFormat register depends on image sensor type and ReverseX and ReverseY feature settings.
(On setting a PixelFormat value to a camera using GenICam functions or register direct access function, user application should get PixelCoding and PixelSize value corresponding to the PixelFormat value and write them to PixelCoding register and PixelSize register because the camera does not have writable PixelFormat register. When user application uses SetCamPixelFormat() function for setting PixelFormat value, application can set PixelFormat specifying PixelFormat value even if the camera is BU/DU series.)
There are 4 kinds of filter layout, GR, RG, GB, and BG layout, in bayer color filter. The following layout is BG layout.

When Bayer type PixelFormat is selected, camera will output each pixel value as is.
Camera instruction manual shows PixelFormat value when ReverseX and ReverseY feature is disabled.
Camera will not accept PixelFormat that the camera cannot output when application writes new PixelFormat value to the camera, which means that camera will accept only one PixelFormat out of GR, RG, GB, and BG PixelFormat. The available Bayer PixelFormat depends on ReverseX and ReverseY feature settings.
ReverseX and ReverseY settings does not affect availability of PixelFormat other than Bayer type PixelFormat.
