Coin Entry (1)
There are two types of coin entry available. Top entry and Side entry.
•Top entry: The validator is mounted into the Channel and Coins enter through to top
of the validator.
•Side Entry: The validator is mounted onto the front plate and coins enter through the
side of the validator.
Diagnostic ‘Bi-Colour’ LED (2)
The bi-colour LED displays a sequence of flash codes to indicate the current operation
status of the validator, and can be used for fault diagnosis when inserting a coin or when in
teaching functions.
Flash Code Sequence: Description:
Constantly ON Validator power on.
1 Flash Coin accepted / Reject lever pressed.
2 Flashes Coin not recognised and rejected.
3 Flashes Coin rejected by validator.
4 Flashes Coin recognised but not accepted (due to inhibit setting).
i-Button Memory Contacts (3)
This connector enables the i-button to communicate with the product. i-button activity is
indicated by the illumination status of the LED.
Support Tool Connector (CPM) (4)
This 6-way connector is used for a MEI Support Tools, such as the CPM (CashFlow®
programming Module).
Route Inhibit Connector (5)
This is a 9-pin connector that provides input from the machine to the validator. Its function is
to modify coin routing. When a specific exit is full, the host machine will signal to the
validator to redirect subsequent coins to an overflow route.
Serial Interface Connector (HII) (6)
This 10-pin connector provides a serial interface to an HII interface.
Separator Connector (7),
This connector is used to connect the validator to the separator.
8 Way DIP switch (8)
This switch is used as an easy configuration tool for the product. The 8-way switch can be
used to change common settings such as enabling/inhibiting coins and setting coin routing.

CashFlow9520 / 9524 / 9528 Design Guide
MEI., 2003 Page 13 Rev: G1
Post-Gate Strobes (9)
The strobes are used to detect the direction & presence of coins passing through the
validator.
Dual Polarity and BCO Interface Connector (10)
When in NON SERIAL mode, this interface is used to connect to the host machine. The
functions provided are:
•Coin outputs A, B, C, D, E, F.
•Coin inhibits A, B, C, D, E, F.
•Coin common output
•Output mode selection
The acceptor will operate in one of two Coin Output modes:
•Parallel - can be positive or negative common
•Binary Coded Output (BCO)
These will be automatically selected by the “Output mode select” line, if nothing is
connected to the output line then the acceptor will default to parallel mode.
Pre-Gate Strobes (11)
This is an integral part of the validator which detects obstructions around the accept gate. If
an obstruction is detected then coin acceptance is inhibited.
Validator Lid (12)
This lid opens outwards when the reject lever is pressed. It allows for clearance of coins
jams and also provides access for cleaning the coin entry paths. It is also used in some
product configuration modes.
Reject Lever (13)
This lever can be pressed to clear any coins that might have got stuck inside the validator
lid.

PRODUCT INTERFACES
Standard Interfaces
The standard interfaces available on CashFlow®9520/9524/9528 validators are Parallel and
Binary Coded Output (B.C.O.). The validator is supplied in Automatic Mode which senses
the type of interface selected by the host machine via pin 8 (Output Mode Select) of the
machine interface connector.
Parallel Mode
This type of interface is a standard 6 coin parallel output interface as used in the ME126/129
products (Dual Polarity).
The coin outputs for A and C can be combined (e.g. A + C, B, D, E, F) to give compatibility
with ME126 validators and can be set by programming the validator. The coin outputs are
factory defined.
If an alarm condition occurs all coin outputs will be activated simultaneously for >600ms.
Multi-Pulse
This will only operate when in parallel mode. This factory set option will pulse the GB 50p
coin output (of a GB profile) four times on validation of a GB £2 coin.
Coin validation Inhibits A, B, C, D, E, F
To inhibit coin acceptance the CashFlow®validator offers six individual inhibit inputs. These
inhibits operate differently for each mode as detailed in the following section.
Parallel Output mode inhibits
The channels that activate the associated coin output will be inhibited when the inhibit is
held High or no connection is made to the relevant input, (e.g. Inhibit A will inhibit coin
output A channels).
Coin Output Common Line
This line allows for operation with positive or negative common systems. The interface self-
configures by sensing the output common voltage supplied by the machine on the coin
output common line, (pin 2 for a 15 way machine interface connector, or pin 3 for a 17 way
connector).
All potentials are relative to the 0V return line to the machine. (Pin 11 for a 15-way
connector and pin 12 for a 17-way machine interface connector).
Negative common operation is selected when pin 2 output common is between 0V to +1.0V.
Positive common is selected when pin 2 is greater than +7.0 volts (Max 12V) with respect to
pin 11.

MEI., 2003 Page 15 Rev: G1
Binary Coded Output (BCO) - UK
Defined by the validator coin output map. When in BCO mode coin output A is permanently
set active to indicate to the host machine that the BCO feature is set.
Coin output A will have a high impedance (approx. 1M Ohm to 0v) if coin output common is
allowed to float. If an alarm condition occurs, coin outputs B, D, E and F will be activated.

The BCO codes operate in a similar way to those used in the UK. Coin output A is active to
indicate to the machine that the Acceptor is in BCO Mode. Coin output C is active when a
correct code is given to the machine. This effectively becomes the check used by the
machine to authenticate that a current shown code is correct. If this value is not active then
the machine will ignore the codes. B, D, E and F become the 4 code states indicating which
coin is accepted.

The BCO codes operate in a similar way to those used in Italy. Coin output A is active to
indicate to the machine that the Acceptor is in BCO Mode. Coin output E is active when a
correct code is given to the machine. This effectively becomes the Parity used by the
machine to authenticate that a current shown code is correct. This should be used in Even
Parity. Coin outputs B, C, E and D become the 4 code states indicating which coin is
accepted.

These inhibits operate for each mode as detailed in the following text.

Automatic Mode - Parallel or BCO Selection
In this mode the status of the output mode input (on pin 8 of the 17-way connector, or pin 7
for the 15 -way connector of the machine interface) selects either the parallel or the binary
coded output interface standards.
A logic high signal to this pin will select parallel mode, setting pin 8 to a logic low will select
BCO mode. If there is no connection made to pin 8 the interface will default to parallel
mode.
Mechanical
Interface connections are via a 17-way header from the standard PCB. This header is single
row of 17 pins on a 0.1 inch x 0.1-inch grid, with a pin size of 0.025-inch square. The
complete interface connector (connector 1) functions are shown on the next page.

Introduction
This section gives the pin assignments for all connector interfaces used on the CashFlow®
validators and it also includes timing diagrams of the signals appearing on the input and
output lines.
Connector 1, Machine Interface.
The interface to the validator from the machine is exactly the same as those that apply to
the MS/ME series validators, with the exception of pin 8 of the 17-way connector.
Connector 1 can accept either 15 pin or 17 pin interface connectors.
