I haven't PCIe-1433 in my hands, but at least user manual says:
" The trigger control and mapping circuitry routes, monitors, and drives the external and RTSI bus trigger lines. You can configure each trigger line to start an acquisition on a rising edge or a falling edge. You also can drive each line asserted or unasserted as a digital I/O line. You can map pulses from the high-speed timing circuitry or the NI 1433 status signals to these trigger lines. Seven RTSI bus triggers and one external trigger—all of which are programmable for polarity and direction—are available for simultaneous use. Additional I/O is available with the NI Camera Link I/O Extension Board (PCIe)."
and then
" Built from high-speed counters, the timing circuitry on the NI 1433 can generate precise real-time control signals for your camera. Map the output of this circuitry to a trigger line to provide accurate pulses and pulse trains. Use these control signals to control exposure time and frame rate."
and one more sentence:
" The SMB connector can be used for front panel trigger connectivity. It can be used as a 5 V input to trigger acquisitions or as a 5 V output to provide status information to your system. For further triggering and DIO needs, use the NI Camera Link I/O Extension Board (PCIe). The I/O Extension Board provides three differential isolated inputs, three isolated outputs, eight TTL inputs/outputs, and quadrature encoder inputs."
May be you don't need 190587A-01L extension board at all and using SMB Trigger Connector is sufficient, because you need just single output.
As first step — connect oscilloscope to the trigger output and try to configure trigger in Measurement and Automation Explorer, may be it is possible to achieve your goal directly from MAX's configuration.
