how to use a RS232 from a other crio targets in one project

[SanderHH]

I'm working on a project that involves two Crio targets: 9036 and 9039. The main VI is located under the 9039 target. However, I need to utilize the RS232 port from the 9036 target within the main VI under the 9039 target. It appears that directly accessing the RS232 port in this manner isn't feasible. Is there a possibility to establish a shared variable to facilitate communication between the two targets and utilize the RS232 port accordingly?

You may be able to use the VISA Server to do the job for you.  I have not done that.  What I would do is create a TCP communication between the two cRIOs so that cRIO1 and send a command to cRIO2.  cRIO2 then performs the serial communications and returns the result to cRIO1.
