Bill Acceptor
Bill Entry
Operation commences when a bill of a suitable denomination, as indicated on the bill
entry display, is inserted in the bill acceptor. The bill may be inserted either end first
but only face up. The unit grips the inserted bill and moves it over the magnetic head
and optical system.
The bill is evaluated and either accepted or rejected. If the bill is accepted, credits are
issued only after the bill has exited the bill acceptor and reached the security stacker.
If the bill is rejected, it is returned to the player.
A bill should be given three read attempts in different orientations before it is classed
as unreadable.
Electronics Assembly
The electronics assembly provides the intelligence that controls all functional,
validation, communications, diagnostic, and display functions. The bill acceptor
electronics consists of a microprocessor board mounted on the main board. The
assembly is mounted on the electronics tray, which can be removed for repair and
replacement. The electronics tray also serves as a mount for a self-aligning connector
that electronically connects the bill acceptor to the stacker.
The main electronics board contains the input connector that connects to the host
machine, the top-accessed DIP switch for bill acceptor functional setup, and the status
LED display.
Figure 9-2 shows the connections to the input/output connector.
Figure 9-3 displays a block diagram of the bill acceptor electronics.
