pulse validators that are inside the unit. If ‘1’ is
chosen, then the program will further prompt for
whether the validator is enabled using a logic-
high (Hi) or a logic-low (Lo) signal; either must
be chosen. Note: the Logic Board can only
control one pulse device, so if a pulse coin
acceptor is installed, a pulse validator cannot be
(see Fig. 1 for the pulse device connection on the
MLB).
ANTI-STRINGING PROTECTION
HARDWARE: STRING:
The fourth submenu inside the ‘Hardware’ menu
is used for setting up or disabling options that
help protect the changer from “stringing”. Select
‘String’, and then choose either to enable
stringing protection (Y), or to disable it (N). If
Yes is chosen, there is a series of three settings
that will follow, explained next, that together
control the behavior of the changer with regard
to stringing.
Max $:
This setting is the maximum dollar
amount that can be accepted by the machine
within the user-set time limit (next setting)
before triggering the anti-stringing protection.
The dollar amount can be chosen anywhere
between $20 and $200 in $5 increments.
Max Time:
The time entered here is the time
limit for the changer accepting the user-set
maximum dollar amount (previous setting). If
the changer accepts the maximum dollar amount
within the amount of time set here, anti-
stringing protection will be triggered. The length
of time can be set to anywhere between 5 and
120 minutes in 5 minute increments.
Shut Off:
This setting controls the anti-stringing
protection, which is the shutting down of the
changer for the time specified here. The changer
can be set to shut down for 15, 30, 45, or 60
minutes, or until the MLB is reset by turning the
power off then back on (‘Reset’).
USING THE HOPPER DUMP FEATURE
HARDWARE: DUMP:
Enter this submenu to enable or disable the
“dump” feature, which will automatically empty
all of the contents of the hopper(s). After
entering the ‘Hardware’ menu, scroll down and
select ‘Dump’. To enable the feature, choose Yes
(Y), and to disable it, choose No (N). Note:
choosing Yes will not initiate a coin dump; it will
only enable them to occur.
Using the DUMP Feature: The following will
work only if the Dump feature is enabled in the
‘Dump’ menu.
1. Open the changer door to give access to the
MLB and the hopper(s).
2. Place a suitable container in front of the
hopper to catch the dispensed coins. On rear
load models, the coins may have to be
scooped out of the coin cup as they are being
ejected.
3. On the Main Logic Board, press and hold
buttons #1 and #2 (Up and Down)
simultaneously, until the hopper(s) begin to
dispense their contents. They should only
need to be held down for a few seconds.
4. Once the hopper(s) are emptying, they will
continue to run until manually stopped by
pressing the Select (SEL) button on the MLB.
They may be stopped at any time, or allowed
to run until empty.
A count of the number of coins being dispensed
by each is displayed on the LCD display. If
the hoppers are completely emptied, this
count will show how many coins were in each
before dumping commenced.

FUNCTIONAL DESCRIPTION OF THE
AC1005/AC2221 SERIES CHANGER
To follow along with this walk-through of your
changer, fill the hopper with coins and turn the
changer on.
1. When power is applied the validator will cycle
twice, and the red Out-of-Service light
flashes then goes out. The LCD screen on
the Main Logic Board (MLB) will display the
Software version installed in the board’s
EEPROM, and its backlight will be ON
continuously. The small red status LED above
the display will begin to blink once per
second in the Standby mode, waiting for
something to happen.
2. During the power-up mode the Main Logic
Board will communicate with the validator
using MDB or pulse protocol. During this time
the Display shows the current total dollars
changed count. The MLB establishes what
type of validator is installed, and
communicates the current program settings
and parameters that the validator needs to
know in order to function (type of bills to
accept, bill pulse value, etc.). The MLB then
asks the bill validator if it’s OK and ready to
accept bills, or if it has errors. This process
takes approximately 10-15 seconds.
3. Also during the power up sequence, the MLB,
using ccTalk, communicates with the coin
hopper. It is also setting up the same
parameters and requests as the bill validator,
but it is also informing the hopper what type
of coins it will be paying (general size and
