Synchronize and change 2 counter outputs continous

[Tobias]

Hello,

I am using a Multi I/O DAQ Card (6110 S-Series).

I have to generate two synchron Pulstrains from which I can change the Frequency in a loop.

My problem is I have one task with two channels. I get them synchronized by Creating the two channels and linking them together getting one task but if I want to change the Pulsefrequency (high ticks / low ticks) I cant do it with the DAQmx write VI because this only works if I have one channel.

Actually my signal should look like this:

--- ---

- ------- -------

--- ---

----- ------- ------

The fist signal is high for some time than there is a break for exactly 2
