7.4.2 Bit Allocation (Pixel Format / Pixel Type) – BM-141GE (monochrome)
In the GigE Vision Interface, GVSP (GigE Vision Streaming Protocol) is used for an application
layer protocol relying on the UDP transport layer protocol. It allows an application to receive
image data, image information and other information from a device.
In BM-141GE, the following pixel types supported by GVSP are available.
With regard to the details of GVSP, please refer to GigE Vision Specification available from
AIA (
www.machinevisiononline.org ).

Important Note :
When Gain is set at -4.5db to -6dB, the
linearity of the video output may be
deteriorated around 100% video output
level. Please confirm the output level
characteristics when -4.5dB to -6dB gain
is set.
