fpga with rs232

[tai68]

I am trying to use sbRIO9626 to communication with ZIgbee . I use DIO83/84 as TxD and RxD . I'd like to know should I define the DIO83/84 or configratue something?

What's wrong with using one of the two serial ports built onto the board?  I think you have to control them through the RT, but I see no reason why that should be an issue.

thank you for your time, but I am confusing your answer. 

What's wrong with using one of the two serial ports built onto the board?

----do you mean " W501, RS-232(COM 1) and W503, RS-232(COM 2) "?

----if yes but I do not use both of them , can I use DIO to communicate with some device?(I mean use "DIO" as TxD / RxD")?

I think you have to control them through the RT..

------yes, I have a  vi  through the RT to receive the data from FPGA

He was asking why you don't want to use the ports that are already there with the API that's already created instead of rebuilding functionality that already exists.  If you want to write your own control, you likely can.  I'm not sure why you would.  Serial communication isn't generally fast enough to worry about using the FPGA.  What are you hoping to gain by doing extra work here?

Thank you for your time ,I solved my question.

Something to keep in mind, others may find this thread later through google.  They'd appreciate if you shared what you did so they can duplicate it.

Hi, actually my question was about how to use dio to communicate some devices, and I made a phone call to ask ni support then they sent me some data.
I think I was asking wrong way ..sorry about that.
