Bill Validator Theory of Operation
For configurations using the Mutha Goose system, communication is done through the
Bill Validator and Brain Box.
For cashless configurations using the SMIB Module, communication is done through the
Bill Validator and the SMIB Module.
1. The bill is read by the bill validator unit, which confirms the validity and the denomination of
the inserted bill. If the illuminated bezel is blinking, the bill is not accepted.
2. If accepted, the bill validator transmits this information to the Brain Box / SMIB Module.
3. The Brain Box / SMIB Module acknowledges this communication and sends a command to
the bill validator to send the bill to the stacker box or reject the bill. Once the bill is stacked the
credits are added to the game.
4. If failures or jams occur during these steps, the terminal will enter into an error condition. In
the event the error still persist, restart the terminal.
UBA® Bill Validator
The bill validator has four-way acceptance (face up/down, right side up/down) and it communicates
to the Cabinet Controller Board through the harness at the back of the UBA. The same harness
pr12VDC from the power supply to power the UBA. The UBA bill validator uses 8Mb Flash
Chips to store the firmware that dictates what currency it is to accept.
