2. For serial communication, using onboard sbrio serial port Loopback pin 2 & 3 (short pin 2 & 3) to simply run the  Example i.e. Simple serial from NI Examples

Did you look at the manual to determine which pins are 2 and 3? I assume the blue wire in your photograph is supposed to be the jumper between transmit and receive. However, if you look at the manual (page 22), it's clear that the two pins you've connected are not 2 & 3. It looks like you've instead shorted pin 3 (transmit) to pin 5 (ground).

Yes I mistakenly short the two pins. But how can I add the additional peripheral (serial ports) to sbrio. Please guide. Thanks

As I wrote before: unfortunately you cannot add another serial port that will be accessible through VISA (unless you don't need access to any of the devices on the 9683, but in that case why would you be using one?). You'll have to implement your own serial driver on the FPGA (or copy code, there are a couple of implementations available on the NI website), and then write corresponding code on the real-time side to send and receive characters.

Can you use the onboard serial port? What is your application?

Nope. I'm looking for an alternate. 

I'm so thankful to you. 🙂

I've changed the RMC Card. Now, I am using RMC 9694. Can I configure serial ports now using DIOs?

Thanks

Chishti,

I suggest you check out the Serial FPGA example available in the NI's website: RS-232 Interface Reference Example for LabVIEW FPGA

Warm regards,

 I've changed the RMC Card now I'm using RMC 9694. Can we do it for RMC 9694? Or we still need that driver in FPGA Code?

Plus I've made the custom RMC card can it be possible to use DIOs as serial pins or we need NI RMC Card?
