3. Set Pattern settings by updating the following parameters inside the Pattern Setting box:

• Bit Depth: bit depth of the image. Allowed values are from 1 to 8.

• Pattern Count: amount of patterns to display in sequence. Allowed values 1 to 96 divided by the bit

depth. For example, if the bit depth is 8, the maximum amount of patterns is 96 / 8 = 12. If the bit

depth is 1, the maximum amount of patterns is 96/1 = 96.

• Pattern Type

– Normal: display the pattern sequence. Available for all bit depths.

– Inverted: display the pattern sequence with each pattern followed by its inverted pattern.

Available for pattern sequences with Bit Depth equal to 1.

– HW Pattern: display a pattern sequence created from hardwired (HW) patterns. See

Section 2.8.1.1 for more details.

• Trigger Type: selects how the patterns are triggered.

– Auto: patterns displayed after end of Trigger Period.

– Command: patterns displayed when the Next button is pressed.

– External (Positive): patterns displayed after an external active high trigger signal.

– External (Negative):patterns display after an external active low trigger signal.

• LED Select: selects which color LED is active (Red, Green, or Blue). See Section 2.8.1.2 for

details about using the "Multiple" setting.

• Trigger Delay: number of microseconds delay after trigger is received and pattern is displayed.

See Figure 2-37.

• Exposure Time: number of microseconds the pattern is displayed. Input 0 to display the pattern

through the whole trigger period. See Figure 2-37.

• Trigger Period: number of microseconds delay between two consecutive patterns. See Figure 2-

37.
