Digital inputs. PFI trigger inpurs

[trigger]

Hi,

I want to be able to to start the data acquistion by the use of digital tigger, say on the rising edge. Do i use the PFI inputs and if so how. Or can use one of the digital input channels. Any help would be grateful. Note that I am using NI PCI 6259 and labview 7.

Regards,
Tadhg

Using one of the PFI lines is actually a great idea.

For analog input, you could try the LabVIEW example VI, "Acq&Graph Voltage-Int Clk-Dig Start" you'll be able to get up and running quickly. You may select which line to trigger from using the controls under "Trigger Parameters".

If you are performing analog output, the "Gen Mult Updates-Int Clk-Dig Start" works in a similar way.
