4.5. Logic mode
The Logic mode is activated if JP1 and JP2 are open. The power must be put off / on in order for the
logic mode to be activated.
4.6. Logic mode normal operation
In this mode, the hopper in started by setting the start level to a voltage between 5 - 24V. The hopper is
stopped if the start level changes again to 0V. When the hopper is started in the logic mode, the
software inside the microcontroller of the hopper board will check the level of the coin-sensor first,
which can be a normally open (NO) or normally closed (NC) type. The software needs this information
in order to determine if a coin has left the hopper during payout. Then the motor is started forward, and
coins will be ejected. After a coin has fully left the hopper, the software transmits an active low pulse of
T_exit ms on the Coin Exit signal of the interface connector. See figure below.

Figure 4: Hopper payout timing
The Busy signal (pin 5) will be low as long as the hopper is running. It will also be low if the low level
plates do not make contact anymore. The hopper is empty then.
When the Busy signal is high, the hopper is ready to accept another payout.
