DI-710 digital I/O configuration

DI-710 digital I/O configuration

I have a DI-710 ethernet device, I would like to control the digital I/O port using Labview. I followed the steps in your web page and I can adquired analogs signals very well with no
complication, but now I trying to send data (integer or booleand) to one of the 8 digital port and nothing happeds. I'm using the active x windaq lib and I can not figuret out how to use properly 
the "DigitalOutput" and "DigitalInput" modules. Some of the questions that I have.

1. How can I set a port  as Digital Out Put in the windaq software?
2. How can I control the exactly channel  to send data using "DigitalOutput" in Labview?

Thanks

Best Regards
