RS-422 Configuration

[Kobi_K]

Hi ,

I have a general question , in LabWindows CVI 2009 I have RS-232 Library....

If i want to work with RS-422 Devices , Is it the Same functions and configuration ?

Or there is another FP file or function library.....??

Thank u

It's pretty much all the same.

RS-422 / RS-485 doesn't support some of the signals in rs-232, such as RI, DTR, CD, etc, so the corresponding functionality in the rs-232 library wouldn't apply.  You open,  configure, close, read, write the port in the same way.

Likewise, if you have a virtual com port for a serial link that's implemented as USB or CameraLink, for example, you use the same "rs-232" CVI library.

"rs-232 library" is a bit of a misnomer, NI should maybe call it the "serial library".  The underlying NI driver is the "serial driver".
