establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

[yogan]

hi

can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?

I want to establish a connection between 2 PC's through  RF modem on client & server side & to set up PPP communication for data transfer.

(I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.

I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions  ... which is working)

can u guide me how to establish connection between 2 RF modem's using LABview?

& how does the data transfer take place between 2 RF modems through RS-232?

is it using TCP/IP?

If you got any links to go abt this issue do send me related links .. or any examples .....

I am currently using Labview version 8.

Waiting in anticipation.. reply ASAP..

thanking you

Regards

Yogan..

Howdy yogan,

Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.

You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.

Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

"Back in the day" before ethernet connections became ubiqitous, TPC/IP over serial was possible using PPP. As far as I know, it still is possible.

I can't tell you how to convince Windows to implement the PPP interface because IT always handled such things.

Once set-up, the PPP link works just like normal Ethernet (but much slower).
