I have a RB-730 response pad that is used with Presentation. The Presentation Extension allows me very easily to use the response pad with Presentation. However this only works for button presses. Button releases are not detected at all. Indeed the list of available buttons shown in Presentation’s response window only shows a single entry for each key. Is there a fix for this so that I can use button releases as well as presses?
As a Plan B, if I delete the Presentation Extension and set up a serial port “longhand”, button presses and button releases are both recognised. However, the codes generated are inconsistent and rather meaningless. I have tried every combination of parameters (baud rate etc) and configurations but have been unable to to find a configuration that generates usable codes in Presentation.
Running under an old Windows XP system I had no problems in the past. The response device itself is rather old (~2007 I think), so I have had to update it to run on Windows 7. The upgrade (using the instructions and software provided by Cedrus) was successful, but could this update be somehow incompatible with Presentation?
