DE2-115 RS232 Configuration

Hi All, I am trying to read a DE2-115 board using LabVIEW via the RS232 port on a Sabrent RS232 to USB 2.0 Converting Cable. When I run the program in LabVIEW I get a message saying that there is a ...

The RS232 interface on the DE2-115 is completely 'soft', meaning that the UART must be completely implemented in custom FPGA code. There is an on-board TTL to RS232 converter, but it is only a level shifting driver/receiver to the 9pin PC compatible connector.

So if you have a functioning UART implementation, and the baud rate (ie, 9600, 115200, etc) and data format (ie, 8N1) match it should work fine.

What code is in the FPGA, and how is it configured? It will make all the difference.
