INTERFACES
•
The “interface” refers to the transfer of electronic data to and from the bill acceptor and the
controlling device. The controlling device in a vending machine is either the machine
controller or the coin mechanism. The signals transferred to the bill acceptor are control
signals which may include:
•
The control system is ready to accept money
•
The denomination of bill to accept
•
Whether or not bills should be returned from escrow
The Talos is capable of operating with the following interfaces:
Vending Interfaces
Non-Isolated Low Level Pulse
Gaming Interfaces
Features
Features included in the interfaces are Escrow, Lockout, Credit Pulse and Out of Service
Line Indication.
Escrow
The bill can be held indefinitely and then can either be accepted or returned prior to being
stacked. Escrow allows a vending machine control system to decide whether or not the last
valid bill inserted will be credited or returned to the user.
Normally, a valid bill will be accepted and held in mid-transport. At this point, the bill acceptor
will transmit the value of the bill. The control system then decides to keep or return the bill.
If the bill was kept, the bill acceptor completes transportation of the bill and transmits
confirmation that the bill was stacked.
Accept Enable (Lockout)
The accept enable feature allows the control system the option of disabling the Bill Acceptor.
This function is controlled by the "Accept Enable" interface lines.
