Is it po

ssible to use the 4 digital i/o lines on a PCI-1409 frame grabber through a RTSI cable which is connected to a PCI-6023E data acquisition board, and can the trig lines on the 68 terminal board connected to the DAQ card be used for this type of static i/o ?This would allow the addition of 4 dig i/o lines in my application. Does anyone know of an example program which shows how to configure these extra lines as digital i/o and control them from the front panel?

The alternative is to buy a 68 pin connector and block for the frame grabber as well. My application is very short of space so this is not really an option.

You can use the external trigger lines on a PCI-1409 as static I/O lines. In order to toggle the state of these lines all you have to do is to call IMAQ Trigger Drive function with Trigger line terminal set to one of the four external trigger lines and also Trigger Drive terminal set to Asserted/Unassorted for a TRUE/FALSE TTL value.
Hope this helps!

Thanks for the answer. The bit i am still unclear about, is whether you can do this through the RTSI bus or whether i need to purchase one of these 68 pin connectors and block for the PCI-1409?

kindest regards,

In order to access those trigger lines you'll need a IMAQ-A6822 bnc connector block. You can output the signals on to the RTSI lines but you'll need a breakout box for the DAQ card in order to access those signals.

I have a breakout box for the DAQ card but not the IMAQ card. I have them connected by a RTSI cable. Are you saying it is possible to access the D I/O signals from the IMAQ card on the DAQ card breakout box, or do i need that IMAQ-A6822 aswell?

thanks again,

Normally you'd use an IMAQ-A6822 for this. I'm not sure if you can route the RTSI signals to one of the PFI lines or not. But if that's possible then you can access them through the DAQ breakout box. Just keep in mind that since those lines are static I/O lines and you'll be routing them through RTSI, you shouldn't use them for applications that require accurate timing.
