4.3.1.1 Set Up External Pattern Mode
Follow these steps to set up External Pattern mode:
1. Enter illumination type, bit depth and number of patterns per frame.
2. Enter required exposure time and dark time.
3. Establish trigger outputs if required.
4. Ensure that the EVM is connected and click Set. If an invalid timings error message displays, adjust
the patterns timings in step 2 to ensure that the timings are within the supported range and click Set
again.
5. To verify that the image projected by the EVM has been updated accordingly, click Get.
6. The frame rate field updates. The frame rate field is not editable. The frame rate mentioned in this field
is calculated as follows:
Frame Rate (Hz) = 1000/[(Exposure Time (µs) + Pre-exposure Dark Time (µs) + Post-exposure Dark Time (µs)) ×
Patterns per Frame] (1)

4.3.2 Internal Patterns Pages
Internal Patterns streaming mode involves projection of patterns created internally by the functional block
of the controller. Select a group of one row or one column patterns to be replicated through the array by
the Controller. The order of display of groups of patterns is configurable.
