Here is some documentation that shows how to retrieve values in an array on the robot that were generated by RoboRealm for doing vision operations.

and here is some documentation that shows how you might send values from a Java client program running on the desktop.

This desktop example doesn't use arrays, but from the previous example, it might give you enough information to make it work.
Hope this helps.
