1INTRODUCTION.
This manual describes the operating mode of the AC-DSP range, coin validators that are part
of the so-called Modular DSP series. The points covered in this document are therefore valid
for the following models of validators:
AC6-D2S
AC6-D4S
A6-D2S **
A6-D4S **
** The previous range of validators called A-DSP is included in the range of
validators AC-DSP. For more detailed information on this point, consult
paragraph 1.2 of the manual "Technical Information"
In this manual the general term AC-DSP will refer to any of the above validators.
For full information on the technical characteristics and operation of these validators, this
manual must be complemented with the corresponding product manual "Technical
Information”available on the Azkoyen website “http://sat.azkoyen.com”.
The AC- DSP validator can operate in three different modes:
Parallel
Timer
Credit.
Each one will be explained in detail in section 3 - Operation.
The selection of one or another operating mode is done using dip switches.

V1_version Feb-2011 5
2CONNECTION AND PINOUT.
The validators AC-DSP have 2 connectors that are accessible to the user.
Figure 1. Connectors accessible to the user.
2.1 Connector J1 (10 pins) for communication with the machine.
It is the main connector for communication with the machine.
Power to the validator is through pins 1 (GND) and 2 (Vdc) for this
connector
The function of each of the pins will vary depending on the
operating mode selected by the user. See section 3 Operation for
details.
2.2 Connector J2 (4 pins) for the communication with the Azkoyen tools.
This 4-pin connector is used to connect the validator software tools (HEUS) and the Azkoyen
hardware interface (TL20).
Section 5 Tools, gives details on the procedure to follow for the connection of the validator
tools.
This connector pinout is detailed in the following table:

3.2 Validator AC-DSP in Parallel mode
The operation of the validator in parallel mode is characterized by giving a pulse (signal), on
one or several pins on the connector, when you enter a valid coin.
The coin value assigned to each pin (or output) will depend on the particular configuration of
each validator and will be a modifiable setting using Azkoyen tools.
These validators have 7 output lines (see the table), which can be:
Dedicated: They use a line for each coin, which means that you will only be able to
use 6 different coins.
Binary: They use multiple output lines to identify a coin which means that the
maximum number of currencies to be used will be 32.

Table 3. Pinout in parallel mode
Input pin 6 works as inhibition in the acceptance of coins (the range of inhibition is
configurable). It works in a general way, i.e. it jointly enables or inhibits all coins programmed.
In this type of operation, you work directly, without any communication with the machine, i.e.
when the validator validates a coin, it consults the inhibition input values and depending on its
value, it accepts (or rejects) the coin and gives a pulse for a duration determined by the
assigned output/s.

Protocol - Modular AC-DSP
V1_version Feb-2011 8
There are a series of parameters in this operating mode whose default values are configurable
and modifiable with the Azkoyen tools:
The duration of the output pulses.
The signal edge of the inhibition signal.
The assigning of outputs.
3.3 Validator AC-DSP in Timer mode.
The operation of the validator in timer mode is characterized by giving an operating time
(power/access) when the programmed price for that time period is reached by introducing the
necessary coins
The pinout of the connector J1 in this operating mode is as follows:

Table 4. Pinout Timer mode
These validators can work in three different modes
Working in continuous mode.
When it reaches (or exceeds) the programmed price, the validator automatically and
continuously gives the time corresponding to the entered price. The value of the
output pin status remains unchanged until the end of the service
If the introduced amount was higher than the price, but insufficient to achieve the
value of another service, the remaining value will be stored.
The output pin is configurable
Input pin 6 works as inhibition in the acceptance of coins. The flank of inhibition is
configurable.

Protocol - Modular AC-DSP
V1_version Feb-2011 9
Example:
Price: €1 Signal for this price: 60 seconds
The user enters €2
The validator immediately gives a signal of 120 seconds on the corresponding pin
Working in continuous mode with start request.
When it reaches (or exceeds) the programmed price, the user needs to request the
service through pin 6. Once this happens, the time will be provided continuously.
For the start request to be valid, it is necessary for pin 6 to produce a change of
status "inactive" state (which can be "0" or "1" as it is configured) to the "active"
state for a minimum of 50 milliseconds. This pin has to go back to the inactive state
during a minimum time of 50 milliseconds to make the sale of the next signal.
If the introduced amount was higher than the price, but insufficient to achieve the
value of another service, the remaining value will be stored.
Figure 2. Signal Times
Example:
Price: €1Signal for this price: 60 seconds
User introduces €2
Until the user requests the service on pin 6, the validator will not send service. Once the
user requests the service, the validator will give a signal of 120 seconds to the
corresponding pin.
Working in Service Request Mode.
When the programmed price is reached (or exceeded) the user needs to request the
service on pin 6 to obtain a service. Once this happens, one service time will be
provided.

Protocol - Modular AC-DSP
V1_version Feb-2011 10
If the remaining amount is sufficient to provide another service, a new request
application is required to start it.
The request signals are sent to pin 6 one by one. For this to happen pin 6 must
produces a change of status "inactive" state (which can be "0" or "1" as is
configured) to the "active" state for a minimum of 50 milliseconds. We need this pin
to go back to the standby state for a minimum time of 50 milliseconds to make the
sale of the next service.
Figure 3. Signal Times
If the introduced amount was higher than the amount required, but insufficient to
reach the value of the price programmed, the remaining value will be stored.
Example:
Price: €1Signal for this price: 60 seconds
The user introduces €2
Until the user requests the service on 6 pin, the validator will not work. Once the user
requests the service, the validator will give a signal of 60 seconds to the corresponding pin.
A new service request is required to obtain the 60 remaining seconds.
In the three working modes described above, you may obtain several signals which provide
information on the Status of the validator:
Counter signal. It is used to count the base coin values that are introduced into the
machine. It is variable and configurable, time "0" and "1" time. For example, if the
base coin is €1, when 2 coins of 50 cents (€1) enters the machine, there will be a
counter pulse to increment the counter, or when 5 coins of 20 cents (€1) enter the
machine there will also be a credit on the counter. This output pin signal is
configurable.
Available Credit signal. Generally used to illuminate a lamp indicating the user's
credit. This output pin signal is configurable.
Warning signal. It is triggered when the time to complete the service is nearing.
The value of the time left of the service is configurable.

Protocol - Modular AC-DSP
V1_version Feb-2011 11
3.4 Validator AC-DSP in Credit mode.
The operation of the validator in credit mode gives a credit signal to achieve the
programmed price. This signal will be a configurable in the "1" time and the "0" time.
The pinout of the connector J1 in this operating mode is as follows:

Table 5. Pinout for Credit mode
These validators offer two operating modes:
Working with continuous pulses.
When the programmed price is reached (or exceeded), the validator automatically
and continuously gives credit pulses corresponding to the amount introduced.
Input pin 6 serves as inhibition in the acceptance of coins. The range of inhibition is
configurable.
Example:
Price: € 1
Pulses for this price: 5 pulses
The user introduces € 2
The validator immediately provides 10 pulses to the corresponding pin.
Working in Service Request Mode.
When the programmed price is reached (or exceeded) the user needs to request the
service on pin 6 to obtain a service. Once this happens, the corresponding service
credits will be supplied.

Protocol - Modular AC-DSP
V1_version Feb-2011 12
If the remaining amount is sufficient to provide another service, a new request is
required to obtain the service.
The request signals are sent to pin 6 one by one. For this to happen pin 6 must
produces a change of status "inactive" state (which can be "0" or "1" as is
configured) to the "active" state for a minimum of 50 milliseconds. We need this pin
to go back to the standby state for a minimum time of 50 milliseconds to make the
sale of the next service.
Figure 4. Signal Times
If the introduced amount was higher than the amount required, but insufficient to
reach the value of the price programmed, the remaining value will be stored.
Example:
Price: € 1
Signal for this price: 60 seconds
The user introduces € 2
Until the user requests the service on 6 pin, the validator will not work. Once the user
requests the service, the validator will give 5 pulses to the corresponding pin. A new
service request is required to obtain the remaining 5 pulses.
In both working modes described above, you may obtain several signals which provide
information on the Status of the validator:
Counter signal. It is used to count the base coin values that are introduced into the
machine. It is variable and configurable, time "0" and "1" time. For example, if the
base coin is €1, when 2 coins of 50 cents (€1) enters the machine, there will be a
counter pulse to increment the counter, or when 5 coins of 20 cents (€1) enter the
machine there will also be a credit on the counter. This output pin signal is
configurable.
Available Credit signal. Generally used to illuminate a lamp indicating the user's
credit. This output pin signal is configurable.

Table 6. Modifiable parameters using switches.
To programme the parameters with dipswitches, follow the steps below:
1. Place SW3, SW2 and SW1 dipswitches with the parameter settings to modify
according to table 6.
2. Put dipswitch SW4 ON. The electromagnet on the acceptance gate will make a short
“click”.
3. Do the appropriate action to set the parameter (see specific indications in paragraph
4.1.1)
4. Put dipswitch SW4 OFF. If the programming was correct, the solenoid on the
acceptance gate will make a long “click”. If the programming was not correct, the
solenoid on the acceptance gate will NOT “click” and you will have to repeat the
process from the start.
4.1.1 How to programme each parameter correctly.
Service price: enter the amount of coins you need to reach the price according to
the value of each coin. The programmed price shall be the sum of the values of the

Protocol - Modular AC-DSP
V1_version Feb-2011 14
introduced coins. If the validator rejects the coin it will not count for the price
programming.
Coins accepted: introduce one of each coin that you want to admit. Other coins
available on the validator will be inhibited and it will not accept them.
Service time: enter the amount of coins you need to reach the time requested
according to the value for time of each coin. The time assigned to each coin should
be specified.
Maximum value programmable 65,535 seconds.
If during the programming, the introduced coin causes the maximum value to be
exceeded, it will be not accepted and its value will not count for the programming.
If the coin is rejected or does not validate properly, it will not be used for
programming.
Token 1 / Token 2
1. Place the dipswitches to be programmed for token 1 or token 2.
2. Put dipswitch SW4 ON. The electromagnet on the acceptance gate will make a
short “click”.
3. Introduce a minimum of 25 tokens that you wish to programme.
4. Put dipswitch SW4 OFF. If the programming was correct, the solenoid on the
acceptance gate will make a long “click”. If the programming was not correct,
the solenoid on the acceptance gate will NOT “click” and you will have to repeat
the process from the start.
To programme the second token, it is necessary to repeat the process.
The value of tokens are fixed (value is implemented in factory when the validator is
programmed) and only you can modify them with a Terminal TL20 or similar.
Activate / Deactivate Wide Tables and Bonus.
The process to follow to activate wide tables / bonus is as follows:
1. Place the SW1, SW2, SW3 dipswitches with corresponding configuration.
2. Put dipswitch SW4 ON. The electromagnet on the acceptance gate will make a
short “click”.

Protocol - Modular AC-DSP
V1_version Feb-2011 15
3. To activate the Bonus, introduce a valid coin that will be accepted. If the
validator rejects it, introduce another coin.
4. Put dipswitch SW4 OFF. If the programming was correct, the solenoid on the
acceptance gate will make a long “click”. If the programming was not correct,
the solenoid on the acceptance gate will NOT “click” and you will have to repeat
the process from the start.
The process to follow to deactivate wide tables / bonus is as follows:
1. Place the SW1, SW2, SW3 dipswitches with corresponding configuration.
2. Put dipswitch SW4 ON. The electromagnet on the acceptance gate will make a
short “click”.
3. Place dipswitch SW4 in the OFF position. The electromagnet on the acceptance
gate will make a long “click”.
4.2 Parameters that are configurable using Tools.

5AZKOYEN TOOLS.
5.1 HEUS.
The HEUS (user tool) software has two basic applications in the management of AC-DSP
validators.
Figure 5. HeUs
A tool for editing and modification of settings. It allows you to modify each one of the
characteristic values in this range of validators detailed in paragraph 4.2.

Protocol - Modular AC-DSP
V1_version Feb-2011 18
A tool for uploading files for configuration and programming. You can download files
directly from your PC with the validator tool HEUS.
Communication between PC (HEUS) and the validator is done via cable right directly from the
RS232 port of the PC to the 4-way connector J2 on the validator.
The 12/24 V power supply will not power the validator through this
connector, it will always be necessary to maintain the validator powered
through the J1 connector.
To know the details of the implementation and management of the HEUS, consult the specific
manual available on the Azkoyen website http://sat.azkoyen.com.
5.2 TL20.
The TL20 is a hardware tool that is used to upload files for programming and configuration in
AC-DSP validators.
Figure 6. TL20
The TL20 programmer will connect to the validator on the 4-way connector on the validator
module J2.
The 12/24 V power supply will not power the validator through this
connector, it will always be necessary to maintain the validator powered
through the J1 connector.
To know the details of the implementation and management of the TL20, consult the specific
manual available on the Azkoyen website http://sat.azkoyen.com.
