5.5.2 DLP LightCrafter Single DLPC900 Trigger Input and Output Voltage Selectors

The trigger inputs on J20 are inputs from external devices to control the pattern sequence. While trigger input 2 is high, trigger input 1 advances the pattern sequence to the next pattern that is waiting for a trigger input. See Reordering a Pattern Sequence using the Edit LUT Feature for more information.

The trigger outputs on J24 are outputs to control external devices. While trigger output 1 frames the exposure time of the pattern, trigger output 2 pulses to mark the beginning of each pattern with a 19.4 μs pulse.

Both input and output triggers have voltage level selectors. Use J19, J21, J22, and J25 to select the voltage as shown in Section 8.1 and Section 8.2. If no voltage is selected, then the onboard logic is not functional and any outgoing or incoming signals are not available.
