generate a long pulse with a different source clock

[steveferguson]

I have configured the 6601 to generate a 1khz train on Ctr0

I would like to feed this into the source of Ctr1 to generate pulses of longer duration.

I use the command DaqmxCreateCOPulseChanTicks to set up my pulse train on Ctr1.

It works if I leave the source terminal as Null "", but it does not work if I change the source.

To change the source, I have wired ctr0 output to the source of ctr1 and use the label "dev1/PFI39" as the source terminal and have tried "dev1/ctr0Output".

I am using Visual Basic 6.

What am I missing?

Hi,

Are you receiving any errors when you use anything except null as your source or is the counter simply not outputting anything? Also, have you tried using "Dev1/ctr0internaloutput" as a source as well?
