USB-6211 special DO pulstrain

[SectorEffector]

Hello,

I have a USB-6211 and I want to generate a pulstrain for a power supply.

The pulstrain is determined in ms on and off time (e.g. 49ms off, 1ms on, 5V).

The length of the pulstrain is infinite, but must be haltet when an error happens.

(I do not understand why I need to configure the length of the train in before hand, I just want on or off.) 

What is the best method to do this? 

Kudos will be given!

Thank you

Can anyone give me a hint please.

You should be able to use the counter output. There are examples to look at (Help>Find Examples>Hardware Input and Output>DAQmx>Generating Digital Pulses). Perhaps Gen Dig Pulse Train-Continuous.
