The Pattern Display LUT Configuration
command controls the execution of patterns stored in the lookup table (LUT). Before
executing this command, stop the current pattern sequence.
Issue this command after any Pattern
Display LUT Definition command is issued.
NOTES:
- This command makes all Pattern Display LUT Definition data
effective and sets the Pattern Display LUT default order which displays all
patterns in the DLPC900 pattern memory in the order they are defined by the pattern
index in Pattern Display LUT Definition.
- When this command is executed any pattern that precedes a pattern
with an input trigger in the Pattern Display LUT Definition, has a black pattern
loaded at the end which causes the system to display a darkness until the trigger is
received to start the triggered pattern. If the triggered pattern is the very first
pattern in the Pattern Display LUT Definition then the very last pattern in the
in the Pattern Display LUT Definition is treated as the pattern preceding
it.

(1) The number of patterns in the Pattern
Display LUT Configuration to display (
NP).
Note: Set this
equal to the Number of Pattern Display LUT entries (NL) to display the sequence
once. Any number can be entered here to display the sequence multiple times. The pattern
will display floor(NP/NL) times and any remainder (R) will display
the first R Pattern Display LUT entries. For example if NP = 27 and
NL = 5 the Pattern Display LUT sequence will display five times followed by the
first two patterns defined in the Pattern Display LUT.
