to Flash memory or a PC file.

Before issuing this command, select the set you wish to write
with the SSN command:
0 = Factory set
1 to 4 = User sets
Input LUT is loaded by LIL, LFS, and automatically at power-
up.
LUT use is enabled or disabled with the EIL command.
Set 0 can only be written from factory mode.
Provided so that user can generate their own LUT's to send to
the camera
Binary file
((2 bytes, LSB first) x (1024 values)) x (4 red taps)
((2 bytes, LSB first) x (1024 values)) x (4 green taps)
((2 bytes, LSB first) x (1024 values)) x (2 blue taps)
32 bytes reserved
2 byte CRC-16 of previous bytes
e.g. PC-30-02k80 would have
1024 words for red tap 1 +
1024 words for red tap 2 +
1024 words for red tap 3 +
1024 words for red tap 4 +
1024 words for green tap 1 +
1024 words for green tap 2 +
1024 words for green tap 3 +
1024 words for green tap 4 +
1024 words for blue tap 1 +
1024 words for blue tap 2 +
32 unused bytes +
2 byte CRC of the above
LUT values are indexed using the most significant 10 bytes of
the video signal
When LUT's are enabled, an indexed value is added to each
value in the video signal
e.g. If the value out of the A/D converter was 4007 then the
index into the LUT would be 4007 / 4 = 1001.75. If the LUT
were enabled, then the value at index 1001 (zero based) in the
LUT would be added to the value coming out of the A/D
converter.
