Using PFi line as trigger for NI 5133

[Anilvs77]

 Hi,

I am trying to use NI 5133 for collecting data for 2 channels at 1 MHz sampling rate. This data is being collected on an engine and I need a reference point for my signal. Can I use PFI channel as an external trigger? I will get a TTL pulse whenever there is a sparking event and I want to start acquisition at this point and collect data for 1 Sec. Can I connect my TTL signal as trigger.. also I need to use only the first high to be treated as trigger and collect data for 1 sec... Please help me out in this.. a bit urgent...

Thanks

Anil
