How do I sych start of while loop with start of Triggered Analog Read

[mike_fit]

I am having problems synchronizing my data acquisition. All acquisition
is started by an external trigger connected to the PFIO channel

I am Using a 6062-e Card with BNC-2120.

I have Analog Input, Analog Output, Counter Input and
Counter output.

I am acquiring 6 channels of analog voltage input from my
linear translation table.

                1 - 3 Tri
axis Accelerometer

                4 Gyroscope

                5 Velocity
Command Signal

                6 Velocity
Output

An  Analog Voltage
Output write starts a specified delay time after the analog read is triggered
externally. It is used for releasing a switch. The analog output is a step that
remains high at a user specified level (+5V) for as long as the analog input is
acquiring.

The raw encoder signal from the motor is converted to ctr0
ctr1 through a chip and is acquired using counter read.

I need to make the counter read start when the Analog input
starts.

I attempted to do this by putting them in a timing sequence,
but it didn't work if the analog read was waiting for the trigger.

Additionally I need to send a single pulse at some delay
time to trigger the frequency generator used as the velocity command.

Is there any way to extract trigger information from the taskto be triggered, so that I can start my loop??

[mike_fit]

I ll try to ask this in another way. How can I make my while loop wait for the analog read to start.

The analog read is triggered externally on the PFIO channel. 

Please Help.!!!

One option is to set DAQmx Read to a Timeout of "-1" in order to have the read block until samples are available.  The code would look something like this:
