5.6 DISCRIMINATORS
The Combo-T device can use Discriminators as payment devices. The Discriminator is a type of
hopper allowing the payment of two different types of mixed coins the same hopper. It has a
device that identifies, by its diameter, the coins in the disk and allows the payment of any of the
two. If there is a coin in the trigger, ready to be paid, that does not correspond with the required
coin, the exit remains closed and the coin returns to the hopper.
The Discriminator communicates with the master through the ccTalk bus. There are specific
commands for the management of this device, relative to the configuration of the types of coins
and the type of payment.
The modes of payment can be set through commands and can be:
• Multiple payment: the master orders the number and type of coins
• Intelligent payment: the master requests the payment of a set amount and the
Discriminator manages the payment taking into consideration the current provision
of coins in the disk. This method is most effective for speed of transaction.
