What gets reset with "retriggerable" for CO pulses?

Question

When using the Trigger property node, and a boolean TRUE wired to the "retriggerable" option, what gets reset? It does not seem to include the "initial delay time." Unfortunately, I must have a user-adjustable delay prior the pulse triggered by another channel. Is there any way to do this? My board is a PCI 6024E. Thanks, matt

Dear Chad,
Thank you for your response. I had tried your suggestion without success earlier. I just added it to a functional vi, with an error result, as follows:
[Error -200452 occurred at Property Node DAQmx Trigger (arg 1) in AI Master_Buffer_AI_CO_10.vi
Possible reason(s):
Specified property is not supported by the device or is not applicable to the task.]
I can't tell if the initial delay, described as applying to the first pulse, gets reset.
I have a very simple task for a simple multi-function vi. I thought the CO pulse would be a good and easy solution, but have been completely stymied. What I am trying to do is record and stream to disk a few analog input channels. I am using one channel as an input to PFI0, to trigger a pul
se out. What I absolutely need is a single pulse only, with a user adjustable delay from the time the trigger is received until the CO pulse.
The periodic signal that drives the vi ranges from 50 to 150 Hz. I have to adjust the various high and low times to only output a single pulse. My vi is almost there, it has a 'phase-locked' pulse that is consistent over time over the bandwidth needed. My last task is to add the delay. I would prefer to solve this using a counter property in order to exploit hardware timing, rather than a software trigger.
Do you have any ideas? Thanks again. I can correspond by email or phone if that is easier, take care, matt.
