RB-730 switching in reflective mode after saving


I would like to send triggers to Acquire (EEG neuroscan) with the Cedrus RB-730 and the accessory connector (ethernet to parallel port connected to the Neuroscan) in a Superlab experiment, but when I go the Input Participant to set up, the RB is detected fine and I set up the RB for general purpose output.

However, when I save the Superlab experiment and I reopen it, it switch to reflective state and it does not send the triggers anymore.

If it matters, at the beginning of the trials the digital output is set to 0 and them to and high.

Any suggestion on how to save the state of the RB-730 for general output purpose or what it may be wrong?

Many thanks,
