1 General information
Interesting facts about the coin validator system
G-13.6000
The validator G-13.6000 is a worldwide established product for the
machine industry in standardized 3 1/2" format. Due to its modular
design and the compact construction the validator is the optimum
solutionfor the amusement and servicesindustry.
Due to the CMOS processor and an electronic system that is done
completely in SMD technique a greater functional variety, an
improved measuring system and a greater protection against
manipulation are possible. Apart from that the system now provides
2x12 coin channels.
Starting with number /1 (marking within the model number) the G-
13.6000 offers the possibility to choose from two configurations
(blocks) with 12 coin channels each. These blocks may be
programmed in a different way and thus can obtain different coin
combinations. This feature is particularly suitable for flexible switching
over from one currency to the other.
Due to the short switching-on time operation in a so-called wake-up
mode is possible. A sensor located in front of the coin slot switches
the coin validating system on. The feature is of great advantage for
devices that are operated with a battery or an accumulator.
The teach mode offers more flexibility to the operator when selecting
coins and token. Without any additional help only by using the teach
mode you can programme quickly coins or token on site.
Like all electronic coin validator systems from NRI the devices of the
series G-13.6000/G-13.7000 can be adjusted by means of a
programming station. For this you need an IBM compatible PC and
the adjustment programme KUNEMP. (For more information refer to
NRI.)
Before changing the device take care that the supply
voltage is switched off.

G-13.6 Characteristic features of the system
2 Characteristic features of the system
Measuring system
The features of the inserted coins are recognized by six measuring
probes that are installed in successive order. Among others the
measuring parameters are the diameter, the thickness, the alloy and
for certain coins also the embossing features.
The obtaines measurement values are compares with the acceptance
bands stored within the 12 channels. If they correspond completely
with a channel the validator values the inserted coin corresponding to
theprogrammed denomination or outputinformationrespectively,
unless the channel is inhibited by the appropriate DIL switch or the
appropriate input line.
After successful measurement a light barrier in the area of the
acceptance gate checks whether the inserted coins fall unhindered
into the cash channel. Within validators containing a sorting the
'accepted coin sensor' is completed by a 'sorting control'. Only after
passing this additional sensor is the appropriate coin signal given.
Thus the whole acceptance area including the falling direction is
supervised,thuspreventingmanipulations.
Adjustment of the channels
12 channels are provided in the coin validators to programme all
required types of coins. Apart from the normal bandwidth for many
types of coins a narrow bandwidth can be adjusted. For types of
coins that are likely to be forged a super narrow channel can be
adjusted to provide the greatest possible protection against misuse.
Several channels can have the same coin value. The corresponding
settings are given on the label (upper row: channels 16, lower row:
channels 712).

National Rejectors, Inc. GmbH, Buxtehude
G-13.6 Characteristic features of the system
Single blocking
Two blocks with six DIL switches each are installed on the back side
of the coin validator. They can be used to block individual coin
cannels. To do this the corresponding switch must be set to the upper
position. (If more than one channel is assigned to one type of coin,
e.g. for old and new coins or for different bandwidths all the switches
must be set to the upper position.)
Six output lines are assigned to the 12 coin channels (not valid for
totalizers). If an inserted coin is recognized the corresponding channel
receives a signal. If one type of coin is blocked externally the
corresponding output line is set to ground potential. Line 6 can be
used to block the whole acceptance (all types of coins).
Sorting outlets
A JST plug is installed on the pc-board. Hoppers or sorting gates can
be controlled by means of this plug. Signals can also be received
since these are bidirectional lines . If e.g. a hopper sends a "Full"
signal the coins are directed into the cash-box.
The validators can also be adjusted by NRI in that way that the return
line sends a sorting signal onto the 10-pole connecting cable.
String recognition
As a protection against manipulation with strings the coin validators
are equipped with a directional accept sensor. That means that a
coin signal is only given when a coin passes the light barrier coming
from the coin insert. To pull coins back out of the device is also made
more difficult by additional design measures.
For devices without a front plate the accept sensor is located on the
left side whereas it is located on the right side for devices with a
front plate.
Apart from that standard coin validators of the series G-13.6000 can
be equipped with a spring for additional support of this safety device.

Teach Mode
By using the teach mode you can programme coins or token in
channel 10 and 11. In all versions of the G-13. validator the teach
mode is programmable. However, a combination of the 2-price-
totalizer with sales counter and the teach mode does not make sense
as the tasks of the switch for single coin inhibit for the 12th channel
wouldoverlap each other.
Using the teach mode:
The validator remains connected in the vending machine.
On the rear of the validator two Dual-In-Line switches are
positioned. Switch no. 12 ON.
Depending on the intention to teach channel 10 or 11, please
switch ON the appropriate switch.
Insert coins or token.
After insertion of the 10th coin (token) the validator gives an
acoustic signal (click of the acceptance gate). The measured
values are now registered.
Turn switch no. 12 OFF.
Also turn appropriate switch for channel 10 or 11 OFF.
Once again the acceptance gate gives an acoustic signal (1 time),
i.e. the programming has been finished successfully.

G-13.6 Characteristic features of the system
In case the acceptance rate for a coin or token programmed by teach
mode is not sufficient, you can programme the coin or token with wider
acceptance bandwidths. Therefore please do the following:
DIL-switch no. 12 ON. Teach mode is now active.
Turn switch for desired channel 10 or 11 ON.
Insert new coin or token at least 10 times.
The acceptance gate gives an acoustic signal (1 time). Coin values
are registered.
Turn channel no. 10 and 11 ON.
Wide acceptance bandwidths are now calculated.
Turn switch no. 12 OFF.
Turn switch 10 and 11 OFF.
Coin or token is now programmed. The teach mode has now be
finished and the channel 10 and 11 are enabled.
In case the acceptance gates gives an acoustic signal twice, the
following reasons could be possible:
coin could not be programmed. It exist an overlapping of the
acceptance limits with already programmed coins/token.
an error has happend during measurement.
the programming has been interrupted.
the acceptance limits could not be assigned to a channel as switch
no. 10 or 11 was turned ON first instead of switch no. 12.
If a coin or token could not be programmed the existing values remain
stored in any case.

G-13.6 Characteristic features of the system
Block switch-over
Starting with model no. G-13/1the validator offers the possibility to
have two configurations, independent from each other. To each of
these 'blocks' 12 individual coin channels are assigned with
appropriate tables (signals, denominations, sorting information). The
programming is done either at NRI or at a service station. Although
both blocks are programmed you can only work with one of them.
This type of validator can be recognized by the label with the extended
indications.
This function is ideal for storing additionally to the actual currency a se-
cond coin combination with individual interface information (table). For
example in case of a currency conversion the actual settings are
deactivated and the new ones are activated. A further application can
be if independent from currency an alternative vending machine
interface is selected.
For standard devices the switch-over is done by only one DILswitch!
On the rear of the G-13 two switch arrangements are positioned. For
switching over from block 0 to block 1 please use switch no. 8 of the
right-hand switch arrangement. Please proceed as follows:
•Switch off power supply.
•Switch on switch no. 8 of the right-hand switch arrangement
–lower position = block 0 active only (left side on label)
–upper position = block 1 active only (right side on label)
•Switch on power supply.
•Check coin acceptance (please refer to label).

G-13.6 Description of the variants
3 Description of the variants
Standard coin validator
Each inserted coin is checked for its type and genuiness and
assigned to the corresponding channel. As soon as the coin has
passed the light barrier a pulse signal (100 ms) is given onto the
corresponding output line and the output is set to ground potential via
an open-collector-transistor. If the light barrier is already blocked when
the coin is inserted the coin is rejected.
Since the channel can be assigned to different outlets by NRI it is
possible to transmit coin signals in a binary code or assign more than
one line to a type of coin.
Casino variant
The Casino variant has two special features:
1. Fast coin acceptance
The coin insert speed can be up to 6 coins/second without any
malfunctionsoccurring or transmitting ofwrongsignals.
2. V2A enforcement
This enforcement in the slot area reduces the wear and tear that
appears in slot machines because of the usually frequent coin flow.
To provide additional protection an accept sensor signal can be
transmitted on the coin return line (line 5) as an option. The coin signal
and the accept sensor signal are given independently of each other.
Since the acceptance gate is triggered at the same time the next coin
can be tested without causing problems (a continuous signal at the
acceptance gate will not cause a problem).

G-13.6 Description of the variants
Totalizers
A totalizer is a coin validator with a credit function. These units have
no channel allocation. Instead the value of the inserted coins is
determined and added up until an adjustable comparison value (price)
is reached. As soon as the pre-set value has been reached the
totalizer triggers a function. There is a total of two output lines that
can be adjusted indenpently of each other. In the Timer variant these
are functional lines, whereas they are price lines in the
2-price totalizer.
Additionally all totalizers are equipped with two DIL switch
arrangements with eight switches each. They serve to adjust the
sales price (not valid for Timer variant/TV totalizer). The adjustment
is done in a binary code. The value of each switch is indicated below
the switch. By selecting a combination of these eight switches any
value between 1 and 255 can be adjusted. The step number serves as
a multiplier for the lowest coin value when calculating the price. The
acceptance limit is 230.
If one of the two prices is set to 0 the corresponding functional line is
always activated and cannot be erased. This is the so-called free
sales mode.
Tokens can be used to activate the functional line directly and
simultaneously increase the credit by the adjusted value of the price
switch.
Multiple sales
In case of inserting too much money there are three possibilities
concerning the remaining credit which can be adjusted by the NRI:
Variant A:
2-price variant
 The remaining credit is erased after a sale.
 Multiple sales are not possible.
 Both prices can be used.
 Acceptance is blocked as soon as the higher price has been
reached.

National Rejectors, Inc. GmbH, Buxtehude
G-13.6 Description of the variants
Variant B:
Multiple sales - type 1
 The remaining credit remains valid after the first price has been
erased.
 Multiple sales are possible.
 Only the first price can be used.
 The second switch is set to the free sales mode.
Variant C:
Multiple sales - type 2
 The remaining credit is erased after 2 minutes. When inserting a
further coin in this period the erasing procedure is cancelled.
 Only the first price can be used.
 The second switch is set to the free sales mode.
Timer variant
The timer function means that the credit is erased or a functional line
is deactivated after a pre-set time.
The time unit is normally set to 60 sec., but it can be adjusted by NRI
to any value between 1 and 255.
The time unit is determined by the value of the inserted coin. Use the
upper switch arrangement to define how much a time period costs
(see fig. 2).
e. g.: lowest coin = 0.10 DM / adjusted multiplier = 10 (2 + 8)
∅price/min. = 1.00 DM

G-13.6 Description of the variants
With each inserted coin the credit is increased by the corresponding
value. The current credit can be displayed.
The lower switch arrangement is used to define the amount of credit at
which the time unit starts (see fig. 3).
e.g.: lowest coin = 0.10 DM / adjusted multiplier = 20 (4 + 16)
∅amount of credit for the start = 2.00 DM
Fig. 3: Adjusting the amount of credit for the start
As soon as the credit adjusted with switch block 2 has been
exceeded, the display will stop showing the credit but will instead
show the time unit. A flashing point indicates the running time.
Simultaneously the functional line 1 is triggered. It remains activated
during the whole time.
If the line for total blocking has not been activated it is still possible to
insert further coins. The time on the display is increased
correspondingly.
Functional line 2 is additionally activated when the last time unit is
running. This signal can be used for a warning sound. When the time
has run out this is indicated in the display. The functional lines 1 and 2
are deactivated.
From the machine the time counting can always be interrupted (high
signal) or started (low signal) via line 8 (reset line) .
The remaining credit is displayed when pressing the return button.

Application of tokens
When inserting a token that is allocated to switch block 1 the credit
is increased by the price of one time unit.
When inserting a token that is allocated to switch block 2 the credit
is increased by the value adjusted at switch block 2. The number of
time units is increased correspondingly.
2-price totalizer
This totalizer variant is also equipped with two switch arrangements
for adjusting the sales prices. The upper switch arrangement serves to
adjust the first price, the second price is adjusted at the lower switch
arrangement.
e.g.: lowest coin = 0.10 DM / adjusted value = 6 (2 + 4)
∅price = 0.60 DM

G-13.6 Description of the variants
The values of the inserted coins are added up until the adjusted price
has been reached or is exceeded. The corrsponding output line is
activated. When the higher price has been reached both output lines
are activated.
When a sales procedure has been completed the blocking resp.
reset line must be activated for 50msec. to reset the credit and to
deactivate the output lines. In the standard adjustment the blocking line
is also used for reset. NRI can change it over to the reset line.
The credit can be shown by means of a display.
Sales counter
On request the totalizers can be equipped with a sales counter. With
this new function the coin acceptance can be blocked after a pre-set
amount of sales. The blocking can only be released by inserting a
reset-token. By inserting this token the sales counter is re-
programmed. It is programmed with the number of sales that are
adjusted at the second price switch. This token is programmed in
channel 12 and can only be used by authorized personnel. When the
blocking is released the pre-set number of sales can be carried out
again.
TV totalizer
This variant is a totalizer with a serial pulse output. The value of the
coins is added up until the pre-set price has been reached. For two
types of coins a discount can be allowed, this is done by higher pulse
numbers.
For the TV totalizer a credit does not have to be reset.
The two switch arrangments serve to adjust the pulse numbers resp.
the price. The first six switches of the upper switch arrangement serve
to adjust the price (e.g. for a game). Here the multiplier (max. 63) is
adjusted for the lowest coin value that is required for reaching the
game price and for transmitting a pulse. When the price has been
reached output line 1 is activated. The credit can be shown by means
of a display. The last two switches are used to change the pulse
frequency:

up up 200 msec. pulse /800 msec. pause
e.g.: lowest coin = 0.10 DM / adjusted value = 10 (2 + 8)
∅price = 1.00 DM
pulse-pause relation = 20 msec. pulse / 80 msec. pause
Fig. 6: Adjusting the price and the pulse frequency
By means of the second switch arrangement the discounts can be
adjusted for those types of coins that are indicated on the label of the
totalizer. This is done by means of four switches that serve to enter the
pulse number (0 - 15).
e.g.: pulse number for coin A = 3 / pulse number for coin B = 7

If required the TV totalizer can also transmit a so-called inventory
pulse (must be adjusted by NRI). It means that directly after inserting
a coin a number of pulses is transmitted to output line 2. The number
of pulses corresponds with the value of the coin. When transmitting the
pulses the coin acceptance is blocked.
As far as the remaining credit is concerned the three variants A - C
described in chap. 3.2 Totalizers are available.
It is also possible to connect a 4- or 5-digit display to this device.
