writing to a DAC card (Digital to Analog) from simulink

Hello

I Would like to know how can i interface a DAC hardware card from
simulink.

I have a digital signal generated in simulink and i like to write it
to a DAC card in order to generate a real analog signal from it.

I am using a WLAN block diagram in simulink that generates a digital
signal that is to be converted to analog and delivered to an antenna
(ieee 80.206.16e standard )

Thanks

Yan

Hi all,
 
I have a PIC microcontroller and a 6031E board and I want my 8 digital bits comming from the PIC port to be converted in labview as an analog signal.  So the 8 bits in are in parallel to the DAQ board and converted to analog voltage.
 
First, I'm converting a sinewave voltage to be read into my PIC uC (A/D).  Do some calculations like differentiate that sinewave, then do D/A with labview. I'm not very good with labview so that part is not working.  I don't have any D/A IC's so i just wanted to quickly use labview to verify that my calculations are correct.
 
is there some kind of example i can use/look for?  i was planning on using the digital input port on my 6031E board but taking the data and connecting it to an digital to analog waveform vi doesn't work.  different sink and sources.
 
Thanks!
