Issue Details

I am trying to use the RS-232 communication on a hardware (sbRIO-9637) connected to the PC through an Ethernet. when I try to open NI-VISA test panel in NI-MAX I get error message as shown below: 

VISA:  (Hex 0xBFFF00A7) The remote machine does not exist or is not accepting any connections.
If the NI-VISA server is installed and running on the remote machine,
it might have an incompatible version or might be listening on a different port.

Solution

Since the hardware is connected through Ethernet which uses the Ethernet protocol (Not RS-232) it will not appear as one of your serial devices on your PC. You can use VISA server on your hardware (sbRIO) to be able to communicate it using VISA. To do this:

1) Right click the Software tab under your hardware in NI-MAX then choose Add/Remove Software 
 
 
2) Choose the compactRIO driver you are using. 
 

 
3) Mark NI-VISA Server as one of the pieces of software to be added.
 

 

Additional Information

If you are using sbRIO-9637 the ASRL1 RS-232 serial port cannot be accessed by the user application when the Console Out startup option is enabled. Therefore if you want to use RS-232 make sure the Console Out startup option is disabled.
