Simple RS-485 capture

[gberry]

Is there a simple application/example program that is non-CVI to log RS-485 data to a file using an 8341/2 with NI-Serial 1.7?  I want to dump 600Kb data to a file.

Hi GBerry,

I found an example in LabVIEW that does the communication. Once you get the date you want you could simply wire it into a Write to LabVIEW Measurement File VI and you'd be set.

Hope this helps.

Oops. My bad.  I was looking for a non labview  and non labwindows/CVI example.  I was hoping for a VISA API interface that I could import into C# so I could "snoop" on a RS-485 bus.

Hi Gberry,

Here's an example in Visual C++. This has no File I/O, but shows how to configure the ports and do serial I/O on them.

Best of Luck!
