4.8. Pulsed mode
The Pulsed mode is activated if JP1 is open and JP2 is shorted. The power must be put off / on in
order for the pulsed mode to be activated.
4.9. Pulsed mode normal operation
In this mode, for each active high or active low pulse on the start input, the hopper ejects a coin.
When the hopper is started in the pulsed 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.
