How do I control the individual lines on the IMAQ PCI-1424

[ADL]

I have a number of cameras that I want to plug into the IMAQ PCI-1424, but in order to start up these cameras correctly I need to ensure that the clock and reset bits are set in the right order. I am trying to figure out how to access the bits in LabVIEW to allow me to programmatically set these bits.

Hello,

PCI 1424 has 4 general purpose static DIO lines (External Trigger 0-3) you can utilize for this purpose. TTL I/O lines are used to start an acquisition or output to control external events. You can program the triggers to be rising or falling edge sensitive. You can also program the triggers to be programmatically asserted or unasserted similar to the function of a digital I/O line or to contain internal status signals (by using the onboard events) or specific pulse widths.
See the shipping triggering examples for demonstration of how to use the triggers.
Hope this helps!

Yusuf,

I want to be able to do the following:
1. Control when the Master_Clock1 starts, using LabVIEW code. Is this implied by INIT.
2. I want to be able to set the state of the Control parameters (pins 33-40) on the IO connector, as they are used in the test system to drive certain camera functions. Again I want to be able to do this through LabVIEW, but cannot find any function that allows you to access these lines.

Many Thanks,

Andy
