SBRIO 9631 RS-232 without FPGA

[Kefir13]

Hello. I have BIG problem for me. I want connect AVR MCU with my SBRIO-9631 using RS-232. I find example wich connected with FPGA. It's very complex for me. Please help me. Very long I can not solve this problem

Hi Kefir13,

If you want to use the built-in RS-232 port on the sbRIO-9631 (it's located next to the network port), you can use the serial VIs (i.e. VISA calls) to read and write from the serial port. In order to communicate with the serial port via real-time, you'll also need to make sure that the CONSOLE OUT switch is set to off. Details on the Serial VIs and functions can be found here while information about connecting serial devices to the sbRIO can be found on page 18 of the manual.

You can also communicate with serial devices via the DIO lines of the sbRIO using FPGA, which is what the example you were looking was probably doing. If you're not very familiar with FPGA, I'd recommend starting with communication via real-time first.

Best Regards,
