1. INTRODUCTION AND DESCRIPTION OF COMPONENTS
This Technical Manual provides technical information corresponding to the coin validators in the
Modular A CCTALK®range.
These coin validators are apparatus that, within the machine, and forming part of it, have the
task of selecting and validating coins introduced into the machine. They are used in leisure,
gambling, parking machines, etc.
This validator has a serial communication protocol compatible with CCTALK®. It has been
designed to allow the interconnection of different coin control systems (hoppers, changers...)
on a simple bus of to wires (a bidirectional data line and ground).
The specification used to implement this communication protocol is the following:
CCTALK Serial Communication Protocol
Generic Specification
Issue 4.3
The use of CCTALK®is free; it can therefore be used without paying licences or royalties.
In the rest of this Technical Manual the coin validators in the Modular A CCTALK range
will be called validator or validators

1.1 MODELS IN THE MODULAR A CCTALK RANGE
Depending on the sensor module, they are divided into two groups:
•A6-6S CCTALK. This is a high sensorisation validator whose sensor module has 6 optic,
6 inductive sensors, and one acoustic sensor, it is recommended when a high discrimination
capacity is required for frauds.
•A6-2i CCTALK. This is a normal sensorisation validator whose sensor module has 6 optic
and 2 inductive sensors.
As for the mechanical format, the possibilities are:
•A. Coin entry at the top.
•AC. Coin entry at the side. This validator can be used with a small front plate.
Normal Short
Therefore, the available models are A6-6S CCTALK, AC6-6S CCTALK, A6-2i CCTALK etc.

ÔModular construction: the measuring device can adapted to the requirements of the
currency.
ÔThe quality of its measurements depends on the characteristics of the Sensor Module
installed.
ÔIt implements the CCTALK®protocol with a wide range of commands. It allows the
teleprogramming of the firmware directly from the serial port.
ÔIt can work in “Safe Mode” which impedes the modification of its characteristics in the field.
ÔThe validator admits 32 types of different coins, of which 2 can be reprogrammed by the
operator on site at the machine.
ÔIt can be programmed for different 4 coin acceptance levels.
ÔThe following security systems are implemented in the validator:
•An effective string detection system, which will foil any attempt at fraud using a string
tied to a coin.
•Anti-return. This system stops the coin from being pulled back up through the validator
with a string after being accepted.
•Control via software of the speed of the coins that impedes coins with very high or low
speeds being credited.
•Control and detection of the entry channel with infrared sensors.
ÔIt is made of the latest generation of plastics that are resistant to wear, they dissipate
static electricity, have high rigidity, and are dimensionally stable at high temperatures and
humidity (low levels of absorption) and are resistant to sea spray.
ÔThe useful life is guaranteed for more than 1,000,000 services.
ÔIt has a hardware test (perform self-check), that when requested by the machine, informs
the machine of the possible anomalies that the validator may have.

1.3 DESCRIPTION OF COMPONENTS
The principle components of the validators in the Arange are:
1. Recuperation lever
Activating this lever will open the validator to free possible coin jams within the validator. The
refund is activated by pressing the red button on the Front Plate, which presses on the side of
the validator door

Technical Information: MODULAR A CCTALK 8
2. Validator door
This is the moving part of the validator. It opens when the recuperation lever or the refund
button on the front plate is pressed.
Validator door
3. Cover
This cover protects the electronic elements in the validator.
4. Circuit board in the sensor module
It has a microprocessor that has a flash memory and teleprogrammable firmware.
JP100: Communication bus for the
exit module
JP101: Serial port
JP102: Programming connection

5. Outlet module
It has a microprocessor that has a flash
memory and teleprogrammable firmware;
the CCTALK connectors can be seen
6. Coin entry rocker
The coin entry rocker is designed to
stabilize the speed at which the coins move
through the interior of the validator.

7. Acoustic sensor
In the lower part of the entry model is the
acoustic sensor. This device receives the
sound made by the coin when it hits the
metallic cylinder on falling into the
validator. The parameters received by this
sensor are very important in the coin
acceptance or rejection process.
8. Metal cylinder
This is a complement to the acoustic sensor.
9. Inductive sensors
Depending on the model, the validator has
between 2 and 6 inductive sensors that
obtain coin parameters related to its
thickness and alloy. Its design favours the
reading of coins manufactured using
bimetallic technologies and/or multilayer.
An example of these technologies is the
two-pound coin.

10212 E 01 - 2006
Technical Information: MODULAR A CCTALK 11
10. Infrared sensors
3 pairs of infrared sensors that obtain
parameters related to the diameter of the
coin.
11. Acceptance gate
When the validator validates a coin, the
electromagnet opens the gate to let the
coin through the accepted coin channel.
12. String detector
Inside the sensor module is the “string detector system.” An electro-mechanical system to foil
any attempt at fraud using a string tied to the coin. The system is based on an infrared beam
passing through a hole in the shutter. The beam is interrupted when the string attached to the
coin tenses and moves the shutter. The validator interprets this signal as a fraud attempt and
inhibits the coin.

13. Sensor module
This element has the majority of the parts
responsible for measuring and control in
the validator. It is a common element of
the validators that have the same sensors,
it is where the different measurements and
controls are carried out to determine if the
coin is accepted or rejected.

Technical Information: MODULAR A CCTALK 13
2. HOW IT WORKS
The validator is a peripheral of the machine, which has total control over the validator. Every
time the machine is switched on or a reset is carried out, the validator inhibits all the coins.
Once the machine starts the communication with the validator, it informs the validator of the
coins that are to be accepted and where they are to be sorted. This programming is stored in
the RAM memory of the validator and can be modified at any time by order of the machine
only.
The machine-validator communication is permanent (credit polling), receiving any credit or
error the validator generates. If communication is interrupted for more than 1 second, the
validator will stop accepting coins.
Once a coin has been introduced, it is analysed by the sensor module and if it corresponds to a
programmed coin that is not inhibited, it is automatically accepted and the validator then
informs the machine of its presence.
To obtain more information on the different commands, consult the CCTALK Protocol manual
for this product.
2.2 PROGRAMMING OF TWO COINS OR METALLIC TOKENS
The command to auto-programme these two coins or tokens are sent from the machine using
the commands [201] REQUEST TEACH STATUS and [202] TEACH MODE CONTROL.
This request is activated using an option in the machine; the validator will be waiting for the
coins or tokens that are to be programmed to be introduced. Once the operator has introduced
25 coins or tokens, the programming of them will be automatically stored on the validator.
The coin numbers available for the implementation of this command are 15 and 16.

4. CLEANING AND MAINTENANCE
The amount of dirt coins leave and the foreign objects and dirt that may obstruct its elements
determine the maintenance the coin validator requires. Use the following guidelines for
cleaning:
zDisconnect the power.
zClean the dirty areas with paintbrush or brush with fine vegetable fibers (never
metal) impregnated with alcohol. Clean with detail:
- The coin guide
- The metal ramp
-The optic sensor holes
- The string detector photocells
- The string detector system
WARNING:
The parts that are held by screws should never be removed. Their manipulation may cause the
validator to measure and detect coins erroneously.
Never use products that contain benzene hydrocarbons. These products severely degenerate
the plastic parts producing irreparable damage.
Never submerge the Coin validator in any liquid.

5. DIMENSIONS
The validator has the same general external dimensions as the “L”: 3.5 type validator. The
validator will fit in the same housing as the “L” validator. The supports are removable and
compatible with market standards. The validator can be installed in the same place as the “L”
type validators except for the differences in coin entry and exit and the fixing points that are
unique to the “A” validator.
