1 General information
This chapter should provide a general overview of the advantages and
options regarding the coin validator G-13.mft with parallel interface (the
G-13.mft totalizer model is described in separate operating instructions).
The first section, however, is designed to help you navigate easily within
these operating instructions.
General information about these instructions
These operating instructions describe the design and operation of the
standard, Casino, BDTA and AMU models of the electronic coin validator
G-13.mft with parallel interface. Chapters 5 und 6 explain the necessary
stepsforstartingupandoperatingthecoinvalidator.Chapter 7explainshow
to clean the coin validator and remedy the cause of a malfunction.
Chap. 9 "Technical data" as well as the appended index and glossary
shorten the search for specific explanations.
The appended chapter "Simple Gaming Interface (SGI)" deals with the
highlightsoftheG-13.mft SGI.

General information about the coin validator
The electronic coin validator G-13.mft (multi-frequency technology) in
standardized 3 1/2" format is based on the tried and tested features of the
G-13.6000. Due to its modular and compact design, the G-13.mft is ideally
suited for amusement, vending and service machines.
The multi-frequency technology isnew intheG-13.mft. Itprovidesmore
flexibilityforthe measuringsensors,multiple scanningofthe coinsinserted
foroptimummaterialrecognitionandevaluationof24 measuringparameters
forreliableacceptanceofgenuinecoinsandrejectionoffalsecoins.Thanks
to the coin validator’s flash technology, software downloads to adapt the
measuring technology, coin data and control software can be executed
quickly and simply. The G-13.mft has 32 coin channels that can be data-
managed, starting from device version /4 and higher, either in a single
memory block or, when divided in 2 x 16 coin channels, in two memory
blocks with different coin configurations.
To be able to react as quickly as possible to new false coins and to enable
youtomakeyourindividualadjustments,thecoinvalidatorcanbeconnected
to a PC programming station which is made up of the configuration and
diagnostics software "WinEMP" (including card reader and licence chip
card) and an NRI tester for power supply of the G-13.mft.
Coins that have not been taken into consideration at the manufacturer’s
company can be configured in the teach mode directly at the coin validator
by inserting coins.

Models and operating modes
The G-13.mft models with parallel interface described in these operating
instructions mainly differ in their machine interfaces.
The G-13.mft with parallel interface is also available as totalizer
model. This model is described in separate operating instructions.

BDTAapplications (withG-18/G-40interface)
The Bundesverband der deutschen Tabakwaren-Großhändler und
Automatenaufsteller (BDTA = German tobacco association) determined
theDTGstandard 2fortheelectricalinterfacetothevendingmachine.This
standardincludethespecificationofthesupplyvoltage,thecoinsignallines,
inhibit functions and the return signal. In addition to further standardization
requirements for validators the measurement quality of validators is also
specified.
For applications in the tobacco sector you can not only obtain the both
NRI coinvalidatorsG-18andG-40butalsotheG-13.mftwiththeappropriate
14 or 16-pole BDTA interface. In order to adapt the G-13.mft to the
dimensions of the G-18.mft or G-40 there is an NRI adapter housing
available.
The standardized BDTA interface does not provide any inverted common
inhibitsignalline.
Applications for Spanish gaming market (AMU)
The AMU model has been designed for the Spanish gaming market. This
model mainly differs from the standard model of the G-13.mft in a specific
coin signal processing and a particular pin assignment.
The AMU coin signal processing excludes a fast coin acceptance for the
Casino mode.

4 Function
This chapter describes how the coin validator works:
• Coin acceptance and coin channels
• Single or double block data-management
• Accepted coin sensors
• Coin impulses and coin signal lines
• Control for external sorting device
• Coininhibition
• Teach mode
• Battery/low-power applications (optional)
• High-voltageupto42 V(optional)
• Inverted common inhibit signal line (optional)
Coin acceptance and coin channels
Thecoin validator has32 "memoryslots"for coinacceptancewhich canbe
assigned up to 32 different coin types or tokens. These "memory slots" are
termed coin channels. The acceptance band of a coin type/token is
allocated to a coin channel and the coin type/token is accepted in that
channel.
Inordertorejectfalsemoneyreliably,frequentlyforonecointype,inaddition
to the normal coin channel, channels with a narrow or even very narrow
acceptance band are set up (see section "Label" in Chap. 3 "Design"). The
limitvaluesofthesecoinchannelsareclosertooneanothersothatfalsecoins
with similar measured values are rejected, if the normal coin channel is
inhibited (see section "Inhibiting coins/activating narrow coin channel" in
Chap. 6"Operation").Narrowandverynarrowcoinchannels,however,also
possess a lower acceptance rate.
Inaddition,itispossibletoallocatecoinswithdifferentmeasuredvaluesbut
identicalcoinvaluestodifferentcoinchannels.Thisishowthecoinvalidator
can, for example, accept old and new coins of the same type.
However,acoinchannelisnotonlyassignedtheacceptancebandofacoin
type but also other coin information which defines further processing of the
coin after its acceptance: e.g. coin signal line and coin impulse number,
inhibit information, sort information for an external sorting device.

G-13.mftstandard/Casino/SGI/BDTA/AMU FUNCTION
19
National Rejectors, Inc. GmbH, Buxtehude
Since in most cases the manufacturer’s customer-specific programming
does not take up all the coin channels, channels which are still vacant can
beassignedcointypesandfurtherinformationdesiredatanytimeusingthe
configuration software. Existing configurations can be changed.
The last eight coin channels 25 to 32 (or 9 to 16 with double block data-

chapter)areintendedtobeusedfortheteachmode.Inthesecoinchannels

Single or double block data-management
Atthemanufacturer’scompany,acustomer-specificsettingisprogrammed
to determine whether the 32 coin channels are to be data-managed in one
memory block or, when divided into 16 channels each, in two memory
blocks (double block data-management).
Ifthedoubleblockdata-managementhasbeenconfigured,theG-13.mftcan
data-manage two separately programmed (memory) blocks 0 and 1 (see

coin types (also currencies), sorting information, etc. However, only one

20 National Rejectors, Inc. GmbH, Buxtehude
Accepted coin sensors
To ensure that accepted coins actually arrive in the cash-box or in an
external sorting device and that coin acceptance has not been tampered
with, accepted coin sensors, positioned in front of the cash-box coin outlet
checkwhether the insertedcoindrops unhinderedintothe cash-boxchute.
Acoinsignalisnottransmittedtothemachineuntilthecoinhaspassedthis
checking function.
If the accepted coin sensors are continuously covered, e.g. by a coin pile-
up, coin acceptance is inhibited.
Exception: Casino model/mode
DuetofastcoinacceptancetheCasinomodeloftheG-13.mftcannotutilize
the accepted coin sensors.
The accepted coin sensors are located in front of the cash-box coin outlet
andcheckwhetheracoinisdirectedintothecash-box.Usually,acoinsignal
is only sent to the machine when the accepted coin sensors notice that a
coinisbeingacceptedanddirectedintothecash-box(seeabove).Tospeed
upcoinacceptanceontheCasinomodel/intheCasinomode,thecoinsignal
is sent before the coin passes the accepted coin sensors. Consequently,
the acceptance gate of the coin validator is easier to tamper with, e.g. with
an inserted coin attached to a string.
For a balanced protection against manipulation, an accepted coin signal
independent of the coin signal can be transmitted via the return signal line
to the machine.
