VISA programming for PXI devices

[Pavitra]

Im using PXI 1031 with celeron 850 mhz embedded controller. Pxi serial interface is connected on one of the slots, and have 2 RS422 serial devices connected.
I wanted to know how to use VISA to communicate and control devices. I am also confused as to running VISA on the PXI controller.
I would also like to know:
1) If the PXI chassis with the serial interface is connected to a PC via the ethernet, how would the I communicate with the Serial devices. would it be detected as a PXI device or as a serial device?
2) If I load VISA on the pxi controller, how would VISA detect the serial devices. would it detect as a Serial device or as a PXI device?
Hope im clear enough.
Please reply at the earliest.

Hello,

The remote connection you use to talk to your PXI chassis should not affect your VISA programming. More specifically, a PXI serial interface should show up as a COM port, and you can use VISA to communicate with it via its resource name (usually an alias such as COM2). How you use VISA will depend on your choice for development platform. For example, in LabVIEW you could use VISA Configure Serial Port.vi along with VISA Write, VISA Read, and VISA Close functions. You may also use a property node for more advanced features. In any event, if you repost with your choice of development environment, I can likely point you to an example you can use to get more comfortable.
