Meaning of flag 50(hex) at the raw frame format

[aviadCielo]

Hy,

I'm using NI-XNET, with c++ at QT environment, OS: Windows 7.

After I'm reading a frame from specific session, I'm trying to figure out from the raw data if a new data arrived.

I noticed that I get flag value of 50(hex) when no new data arrived.

What is the meaning of that flag?

Thanks for advance,

Aviad

Hello aviadCielo,

If you're using the raw data format, you should check out the XNET Hardware and Software Manual:

http://www.ni.com/pdf/manuals/372840e.pdf

See page 4-537 for info on what the raw format looks like.

But if you're just trying to make sure you only read each frame once, you might just want to use Frame Input Queued mode (see page 4-15 of the manual).

Thanks for the replay!

Of course I read the manual before asking my question, but I do not find something about the specific flag 50(hex).

I'm polling all data from the network, and use 'StreamIn'.

Thanks again,

Aviad

Can you post an NI I/O Trace capture? I am not seeing it on my test setup.
