1.5.2 DLP LightCrafter Dual DLPC900 Trigger Input and Output Voltage Selectors

The trigger inputs on J23 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 in the sequence on every pulse.

The trigger outputs on J27 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.

Both input and output triggers have voltage level selectors. Use J22, J24, J25, and J28 to select the voltage as shown in Figure 2-4. If no voltage is selected, then the onboard logic is not functional and any outgoing or incoming signals are not available.
