6.4 The relationship between tap geometry and frame rate
In the EL-2800-CXP, the frame rate is related to Pixel Format, Sensor Tap Geometry (sensor readout
system), Tap Geometry (camera output format), Bit Rate and Link Configuration.
The following table 15 shows these relationships.

Note: 1) Mono, Bayer or RGB is selected in the pixel format. The setting parameters for Mono or
Bayer are the same.
2) The camera output format to be used is selected in Tap Geometry.
3) If 1X–2YE is selected in Tap Geometry, Sensor Tap Geometry is automatically set to 1X2–
2YE. If IX–1Y is selected, the customer should choose 2XE–1Y or 1X–1Y in Sensor Tap
Geometry according the application.
4) Link configuration should be selected 6.25 Gbps if 1X-2YE is selected in RGB pixel format.
In other cases, the customer can choose either 3.125 Gbps or 6.25 Gbps according to the
application.
