CVI and 1Mbits data stream

[hhnguyen]

Hello

I have read about lab Windows CVI VISA lib, which is designed for serial instruments.  I have a burst of 1M bits/sec serial data coming off a interface board,  I would like to know if CVI VISA can handle that high a data rate and how should I set it up?  Are there any examples or tutorials that I can learn from?  My plan is that if I can use CVI to collect the burst of data maybe thru the PC parallel port, which has extra pins for handshake signals in case I do need them, and then parse the collected data in between bursts.

Thanks in advance for any inputs and comments

Regards
Hung

Hung,

VISA should be able to handle 1 Mbps without an issue.  The real question is can your prallel port?  I would first verify that your port can support that high of a transfer rate, then you could use VISA with CVI.  I would download the latest VISA drivers, which install with support for CVI.  Once they are installed you can open CVI, go to Help >> Find Examples and browse for Hardware Input and Output.  You should have the option to select some serial examples for you to use. 

Hope this helps!
