Standard 3.5 inch format.
There are four protruding pins on the sides for anchoring the unit in place.
The following components are located at the top of the unit:
•The coin entry, which can be fitted with various parts to adapt it to the machine
coin slot.
•The coin entry adapter consisting of two parts, one fixed and one moveable.
There are various adapters available in heights of 6, 10, 12, 16 and 18 mm.
•The coin return lever, used to unblock jams and recover coins in the selector.
The following components are located at the bottom of the unit:
•The accepted coin exit, where coin passage validation optical sensors are —
located on the left.
•The rejected, unrecognised and disabled coin exit —located on the right.
On the front, there is the selector identification label with references, configuration
code, coins programmed for recognition, etc.
At the back there is a lid that protects the circuit card and provides access to three
connectors:
§iPolarised 10-way connector: 2 rows of 5 contacts each, with a contact
pitch of 2.54 mm for connecting power supply and parallel interface to the
vending machine.
§iPolarised 4-way connector: for connecting power supply and serial
interface to machines with cctalk protocol (optional).

§i4-way programming connector for workshop coin programming and
reloading programs.
§4 switches used to disable coins, modify acceptance tolerances and field
programming of new coins. The switches can also include other functions
that will depend on the recorded application.

(JOFEMAR APPLICATION)
4. APPLICATIONS.
The selector is factory configured to work with one of the following applications:
Game Validator: Mainly used in machines.
Jofemar Validator: Mainly used in Jofemar machines and coin changers.
cctalk Validator: For machines with this particular interface
There is a specific program for each of these applications which needs to be loaded in
the selector’s flash memory.
4.1. Gaming application.
For this application the selector has to be connected to the machine with the 10-way
connector.
Signals are assigned to pins as follows:
12345678910
+12 V 0 V M4 M1 M2 INH. M3 M5 M7 M6
Pins 1 and 2: Power supply +12 Vdc
Pins 3, 4, 5. 7, 8, 9 and 10: Signals of coins M1 to M7.
They are open collector NPN transistors with the emitter connected to 0 V. The
selector writes a coded signal for the recognised coin saturating the transistors for a
maximum period of 10 ms and a minimum period of 1 ms.

MNP64ENV00 Date: 03-2007 Rev. 03Page 9of 16
Pin 6: Coin disabling signal. On standby +5 Vdc using an internal pull-up resistor.
The selector is enabled by applying 0 V on this pin.
The M1, M2, ... M7 signals provide a code when a coin is recognised (tmax. 10 ms). If
the machine decides that the coin should be accepted it should indicate this to the
selector using the coin disabling line setting it to 0 volts for a tmin. of 2 ms for a tmax.
of 10 ms. At this time the selector will enable the coin acceptance electromagnet,
allowing this coin to go to the recognised coin exit and will remove the coin code of
lines M1, M2, ... M7.
The optical validation sensors located on the path of the accepted coin exit confirm
that the coin has gone through, generating again the same code for the accepted coin
in lines M1, M2, ... M7, for 50 ms.
If the selector does not validate the coin with the coin passage validation optical
sensors, the 50 ms coin code signal (2nd information) will not be provided.
If, on the other hand, you do not wish to accept the coin, the coin disabling line should
not be taken to 0 V, and after 10 ms the selector will eliminate the coin code signals
and a new cycle will begin.
The set of 4 microswitches is used to disable coins, among other things, so you need
to know the configuration programmed in the selector to know the function of each
switch.
4.2. Jofemar Application.
For this application the selector has to be connected to the machine with the 10-way
connector.
Signals are assigned to pins as follows:
12345678910
+12 V 0 V M4 M1 M2 INH. M3 rec/pres nc Nc
Pins 1 and 2: Power supply +12 Vdc.
Pins 3, 4, 5 and 7: Signals of coins M1 to M4.
They are open collector NPN transistors with its emitter connected to 0 V. The selector
writes a coded signal for the recognised coin saturating the transistors for a maximum
period of 10 ms and a minimum period of 1 ms.
Pin 6: Coin disabling signal. On standby +5 Vdc Using an internal pull-up resistor.
The selector is enabled by applying 0 V on this pin.
Pin 8: coin recovery / presence signal.
Open collector NPN transistor with its emitter connected to 0 V
Pins 9 and 10 have no function assigned in the Jofemar application.
The M1, M2, ... M7 signals provide a code when a coin is recognised (tmax. 10 ms). If
the machine decides that the coin should be accepted it should indicate this to the
selector using the coin disabling line setting it to 0 volts for a tmin. of 2 ms for a tmax.

MNP64ENV00 Date: 03-2007 Rev. 03Page 10 of 16
of 10 ms. At this time the selector will enable the coin acceptance electromagnet,
allowing this coin to go to the recognised coin exit and will remove the coin code of
lines M1, M2, ... M4.
The optical validation sensors located on the path of the accepted coin exit confirm
that the coin has gone through and, should the response be positive, the same
accepted coin code is generated in lines M1, M2, ... M4 for 50 ms.
If, on the other hand, you do not wish to accept the coin, the coin disabling line should
not be taken to 0 V and, after 10 ms the selector will eliminate the coin code signals
and a new cycle will begin.
If the selector does not validate the coin with the coin passage validation optical
sensors, the 50 ms coin code signal (2nd information) will not be provided.
In this case, the validator has two exit codes for each programmed coin, which can be
selected using switch no 2:
SW.2 OFF code 1.
SW.2 ON code 2.
The recovery signal will only be generated in this application when the coin return
lever is moved and it is a sequence of two pulses of 1 ms separated by 1 ms.
4.3. cctalk application.
The cctalk Validator application is for those machines that use this protocol and type
of connection between machine devices.
For this application you should connect the selector with the polarised 4-way
connector.
Connections:
ØPin 1:+12 Vdc
ØPin 2: ---
ØPin 3:Ground.
ØPin 4:Data.
There are is coin disabling via switches in this application.
This application integrates a communications protocol called cctalk which allows for
the following:
ØProviding information on manufacturer, serial number, program version, etc.
ØThe possibility of testing the selector.
ØProviding information on recorded coins.
ØEnabling coins that need to be validated.
ØReporting on coins inserted, accepted, etc.
There is a command document available that is recognised by this validator.
