The Notch line is active Low. For a valid low pulse, voltage must be lower than .7 VDC and the high pulse should be 4.5 VDC. The ticket run lin (or enable pulse) is active high which must be 5 VDC logic, not 3.3 VDC. Use DL-1275 protocol setting if available if you are having trouble getting tickets to load to your card swipe system. This protocol is considered the standard for ticket mechanisms, 50 ms on, 50 ms off resulting in 10 tickets per second.
This game uses two different brain boards. Old brain boards are red. New brain boards are green.
Old brain board: It can accept a pulse of 50ms on, 50 ms off resulting in 10 tickets per second.
New brain board: It can accept a pulse of 20 ms on, 20 ms off resulting in 25 tickets per second.
