Coin Entry (1)

There are two types of coin entry available. Top entry and Side entry.

• Top entry: The validator is mounted into t he 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 f lash codes t o indicat e the current operation
status of the validator, and can be used f or 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 set t ing).

i-Button Memory Contacts (3)

This connector enables the i-button to com m unicat e with the pr oduct . 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 f rom 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 overf low 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 separ at or .

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.

Post-Gate Strobes (9)

The strobes are used to detect the direct ion & presence of coins passing through the
validator.

Dual Polarity and BCO Interface Connector (10)

When in NON SERI AL mo de, t h is int er face 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 t he validator which detects obst r uctions 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 clear ance of coins
jams and also provides access for cleaning the coin entr y paths. I t is also used in some
product configuration modes.

Reject Lever (13)

This lever can be pressed to clear any coins that might have got st uck 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 m achine via pin 8 (Out put Mode Select) of the
machine interface connector.

Parallel Mode

This type of interface is a st andar d 6 coin par allel 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 output s will be activated simultaneously for >600ms.

Multi-Pulse

This will only operate when in parallel mode. This factory set option will pulse the G B 50p
coin output (of a GB profile) four times on validation of a G B £2 coin.

Coin validation Inhibits A, B, C, D, E, F

To inhibit coin acceptance the CashFlow® validator offers six individual inhibit inputs. T hese
inhibits operate differ ently for each mode as detailed in the following section.

Parallel Output mode inhibi ts

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 self­configures by sensing the output com m on 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.

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 com mon 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 act ive 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 . I f this value is not active then
the machine will ignore the codes. B, D, E and F become the 4 code st ates indicating which
coin is accepted.

Automatic Mode - Parallel or BCO Selection

In this mode the status of t he out put mode input (on pin 8 of the 17-way connector, or pin 7
for the 15 -way connector of the machine int er face) selects either the parallel or t he binar y
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 connect ion m ade to pin 8 the interface will default to par allel
mode.

Mechanical

Interface connections are via a 17-way header from the st andard 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 sq uar e. The

The CashFlow® 9524/9528 differs from the CF 126/129 with regard to coin rout ing
priority. Coins can be routed to any exit as primary and secondary route. The
product defines the exit depending on the type being set as primary or secondary.

Example: If the chosen Primar y Route = ( a) , the only Secondary routes available
can only be (b), C, D or B. Theref or e ( d) and (c) cannot be used as a secondary

Y-chute Interface Connector

Connections to the Y-chute are made with a Molex type 6471 19-way. This connector is
fitted to the dual entry (coin and token) system only. It provides an interface for the machine
to inhibit acceptance of any coin/token and also gives a signal to the validator to inhibit coins
during token input and to inhibit tokens during coin input.

This interface is not supplied with the single entry system.

Dual Entry System

In dual entry systems the Y-chute form s t he interface between the validator, Y-chute and the
machine. The latter uses the Y-chut e int erface and the validator interface as its main
connection points. The coin outputs are signalled from the validator interface.

The coin inhibits are connected to the Y-chute interface and the inhibit signals are fed back
to the validator interface by the host machine int er face wiring, as shown below.

Sample multiplexed implementation - Negative Common Strobe

Output common can be left floating for multiplexed implementations. However the minimum
turn on time when output common was floating is 15 micro seconds. I f the polarity is
established on output common by means of a weak pull up (for -ve com) or pull down (-ve
com) the turn on time can be reduced. In the case above, t he m aximum t im e from the
output common being strobed to t he out put being true is approximately 1 micro second.
See the diagrams below for sample m ult iplexing im plem entation.

If output common is changed form negative to positive common (or vice versa) during
polling, the state of any coin output cannot be guaranteed for 15us.
