Output look-up table content 9.5.2.
The user look-up table is loaded by command OLUT and entries can be retrieved by OLUT?
Command format: OLUTy
Command format: OLUT?x
Return Message: y
where x indicates the video level (in GL) from the processing core and y represents the resulting video
level (in GL) at the camera output.

To fill the OLUT, it should first be opened through the OLUTBGN command. If an OLUTy command is
received without the OLUT being opened, error 121 is issued.
Then the 1024 LUT entries should be provided by sending 1024 OLUTy commands. If more then 1024
OLUTy commands are received, error 123 is issued and the OLUT-status is reset.
The full-scale range of the OLUT is always 1023. Optional down-scaling the output resolution to 8 bit
is done after the OLUT.
Output look-up table end 9.5.3.
After filling the output look-up table with 1024 values, the table should be closed. This is done through
the OLUTEND command.
Command format: OLUTEND
If the camera did not receive exactly 1024 entries, error 122 is issued and the OLUT-status is reset.
Output look-up table enable 9.5.4.
The user look-up table can be enabled or disabled by means of the OLUTE command.
Command format: OLUTEx
Command format: OLUTE?
Return Message: x
Where x is set to 1 for enabling the OLUT and 0 to disable the OLUT.
Camera Link parameter settings 9.6
Introduction 9.6.1.
The active period for each line expressed in the number of clock cycles equals the number of pixels in
a line (Image Width) divided by the number of taps. The number of pixels is programmed by means of
the ROI command. At full resolution the Image Width equals 2048 or 4096 pixels (2000 or 4080 at 10
tap Camera Link configuration). The number of taps is programmed by the first parameter of the OFRM
command. Expressed in seconds the active time can be calculated with the formula in figure 9.2.
The inactive period (tGAP in figure 10.1) is the Lval gap time which is programmed as the second
parameter of the OFRM command. tGAP = Lval gap / fclk
