dual analog output on PCI-MIO-16E-1

I want to reate a VI that controls two analog output channels and simultaneously measures 4. The output and input are to be made at different sampling rates. I´ve found a good starting point in the "Simul AI/AO Buffered trigger (E-series MIO).vi" provided in the examples. Can you put two AO write .vi in "series".I attach the example. My output process is rather slow about 1 update/s.

The best way to actually do this is to use one AO Write but use it for both channels. This will allow you to perform simultaneous analog output on two channels. I'm attaching ane example VI I found on NI's website which demonstrates how to do this. I hope this helps you out.
