What is the problem that you think is happening to your Jokerz? I have a Cyclone. Are you asking whether on test the Q7 and Q15 alternate going high and going low. or just fire once going from high to low and never rotate back?
When I start my test it will start with Opto closed and then an H will appear on the Alpha numeric Display 7 times then it slows down and whatever it ends on it reads, then it starts again doing the prizes in order.
I can check tomorrow about going High or Low, but I am at office and my tools are are home so this is all I can offer tonight.
The H i believe shows up telling you the Opto is open (or being interrupted)
