RobotStudio Integrated Vision and In-Sight Explorer camera emulator

Hi

what is the correct way to use Cognex In-Sight camera emulator with virtual controller? I do not want to use RobotStudio camera emulator. In RAPID, I can set Cognex camera emulator to program mode and I can load certain job to camera emulator and I can read thatwhat job is loaded, but CamSetRunMode gives communication timeout. Am I missing something?
