INTRODUCTION G-13.mft MDB/S1

General information about the coin validator G-13.mft with MDB/S1 interface

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 is new in the G-13.mft. It provides more
flexibility for the measuring sensors, multiple scanning of the coins inserted
for optimum material recognition and evaluation of 24 measuring parameters
for reliable acceptance of genuine coins and separating out of false coins.
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 model /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
you to make your individual adjustments, the coin validator can be connected
to a PC programming station which is made up of the configuration and
diagnostics software "WinEMP" including card reader and the tester
G-19.0641. With the aid of the Palm handheld software "PalmEMP2" you
can configure the coin validator directly at the machine independently of the
PC.

Coins that have not been taken into consideration at the manufacturer’s
company can be programmed in the optional teach mode directly at the coin
validator by inserting coins.

G-13.mft MDB/S1 INTRODUCTION

Advantages

• Acceptance speed of 2 coins per second

• Coin channels that can be inhibited individually or in groups

• Teach mode for 8 coin channels

• Operating and manipulation safety provided by optical accepted coin
sensors in the coin outlet area

• Interface for connection to a programming station or Palm handheld
which makes immediate reaction to the use of false coins possible

• Multi-frequency technology for reliable coin recognition

• Flash technology for uncomplicated and time-saving firmware
updates

• Optional sensor for increased protection against manipulation in the
cash-box chute

Models

The G-13.mft is available as an MDB model and as an S1 model. The S1
protocol is an MDB protocol specified for NRI coin validators and differs from
the standard MDB protocol with respect to commands and restrictions for
mains supply and sorting.

Both models of the G-13.mft are available with top or front entry. The
G-13.mft with front entry usually has a MIDI front plate or a MINI front plate
fitted to the left-hand side of the device (see Chap. 3 "Design"). The device
is, however, also available as a front entry model without front plate.

DESIGN G-13.mft MDB/S1

Coins inserted into the coin validator pass through the coin insert funnel 2
into the measurement and validation area of the device, in which their coin
properties are compared with the values of the stored acceptance bands.
Coins rejected by the coin validator pass into the return area 4, Fig. 1a/5,
Fig. 1b, and coins accepted for sale leave the device through the coin
outlet 5, Fig. 1a/4, Fig. 1b, and are fed into the cash-box or an external
sorting device. (See Fig. 1a and 1b)

Switching blocks

On the rear, the coin validator is equipped with
two switching blocks with 10 DIL switches
S1.1-10 and S2.1-10 each.

S1

S2

Depending whether your device was programmed for coin data-management
according to a factory-made setting for one or two memory blocks (B-0 and
B-1, see label), the DIL switches will have different functions (see also
section "Single or double block data-management" in Chap. 4 "Function").

On the rear of the device you will find a brief description of the
individual switch functions.

Switch assignment with double block data-management (B-0 and B-1)

Coin channels or the coin types assigned to the coin channels can be
individually inhibited using the first eight DIL switches of the upper switching
block S1 and the lower switching block S2 (see section "Inhibit coin
channels" in Chap. 6 "Operation").

The ninth DIL switch of the upper switching block S1 does not have any
function.

The tenth DIL switch of the upper switching block S1 is used to select the
memory block (see section "Select memory block" in Chap. 6 "Operation").

The lower switching block S2 is used to teach coin types or tokens in the
teach mode (see section "Teach mode" in Chap. 6 "Operation").

14

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 DESIGN

Switch assignment with single block data-management

Coin channels or the coin types assigned to the coin channels can be
inhibited using the first eight DIL switches of the upper switching block S1.
To do this the DIL switches are assigned a coin channel randomly. A group
of selected coin channels can be assigned to a switch to inhibit a number
of coin channels (see section "Inhibit coin channels" in Chap. 6 "Operation").

The ninth and tenth DIL switches of the upper switching block S1 do not have
any function.

The lower switching block S2 is used to teach coin types or tokens in the
teach mode (see section "Teach mode" in Chap. 6 "Operation") and to inhibit
these taught coins in the normal operating mode.

Return lever and return button

The return lever (1, Fig. 1a) on the top of the device is operated using the
return button on the vending machine if the coins which have already been
inserted are to be returned or a jam caused, e.g., by coins which have
become stuck needs to be removed. Operating the return lever opens the
measurement and validation area of the coin validator so that all objects in
the coin validator are transported into the return area.

Devices with front entry through a front plate do not have a return lever. Here
the measurement and validation area is opened by pressing the return
button (1, Fig. 1b) on the front plate.

DESIGN G-13.mft MDB/S1

Interfaces

At the bottom right-hand side on the rear of the coin validator there is a
10-pole connecting plug to the vending machine, and on the left-hand side
at the centre there is a 3-pole JST plug for connecting an external sorting
device. On the left-hand side, there is the interface to the PC programming
station and the Palm handheld. (See Fig. 1a and 1b)

Interface – vending machine

The coin validator is connected to the machine via the serial MDB interface 8
(see Fig. 1a and 1b) and a 10-pole cable via which it can receive information
from the vending machine or send information to the vending machine. The
machine operates as a master and the G-13.mft as a slave. The master can
communicate with several slaves (e.g. coin and bill validator). To ensure
unambiguous communication each device has its own MDB address. The
address of the G-13.mft as an MDB model is "01", and "15" as an S1 model.

The G-13.mft as an MDB model does not fulfil the MDB specification
on two counts, i.e. the specified voltage range and the electrical
isolation of the communication lines.
If a supply voltage of 42 V max. and electrical isolation are
desirable, an MDB converter G-55.0360 can be ordered from NRI
(ordering code 23627).

You can obtain further information about the MDB and S1 interface:

• in the "NAMA document MDB/ICP 2.0" (www.vending.org) and

• in the NRI S1 specification for the G-40 S1, which will be placed at
your disposal upon your request.

You will find a list of the commands implemented in the G-13.mft in
Chap. 9 "Technical data".
Please refer to the section "Pin assignment and connection
diagrams" also included in Chap. 9 "Technical data" for more details
on the assignment of individual plugs (pins).

G-13.mft MDB/S1 DESIGN

Interface – configuration (WinEMP/PalmEMP2)

To configure the coin validator the device is connected to a PC or a mobile
Palm handheld. For this purpose the G-13.mft has on the right-hand side a
10-pole PCB direct plug 10 (see Fig. 1a und 1b), which can be used to
connect the coin validator to the PC via a tester and card reader or to a Palm
handheld (see Chap. 5 "Starting up"). The device is set by means of the
configuration and diagnostics software WinEMP or PalmEMP2 (see separate
software instructions).

Interface – external sorting device

On the rear of the device, there is a 3-pole JST plug 9 (see Fig. 1a and 1b).
This plug can be used to control sorting gates for sorting inserted coins (see
sections "Control for external sorting of accepted coins" in Chap. 4 "Function"
and "Pin assignment and connection diagrams" in Chap. 9 "Technical
data").

The 3-pole sorting plug is made by the JST company and has the
type designation "ZH connector", 1.5 mm. You can obtain further
information about the plug at the Internet address www.JST.com.

G-13.mft MDB/S1 FUNCTION

4 Function

This chapter describes how the coin validator works, using the route which
an inserted coin takes in the coin validator:

• Coin acceptance and coin rejection

• Coin channels

• Single or double block data-management

• Accepted coin sensors

• Optional string recognition

• Control for external sorting device

• Inhibit coin acceptance

Coin acceptance and coin rejection

Coins inserted into the coin validator pass inductive and optical sensors
which check the coins and there they generate individual measurement
values. Due to the special design and arrangement of these sensors, each
coin is checked for its material properties and dimensions. An upper limit
and a lower limit are stored for each coin type, a so-called acceptance band
so that the coin validator knows whether to accept a coin or not. If the
measured values or the coin are within the acceptance band, the coin is
accepted for sale when it has passed the acceptance gate and accepted
coin sensors, but if they are outside the band, it is rejected and directed into
the return area.

The limit values of the acceptance bands are programmed by the
manufacturer according to the customers’ specifications, but can be
adjusted with the WinEMP PC configuration software or PalmEMP2.

Following a reset operation, the coin acceptance function is disabled
and must be enabled again by the vending machine.
As a standard feature, the G-13.mft refuses each further
acceptance of a coin if the G-13.mft has not been activated by the
vending machine within the last 2 seconds or if the last accepted
coin has not yet been scanned by the vending machine.

National Rejectors, Inc. GmbH, Buxtehude

19

FUNCTION G-13.mft MDB/S1

Coin channels

The coin validator has 32 "memory slots" for coin acceptance which can be
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.

In order to reject false coins reliably, frequently for one coin type, in addition 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
limit values of these coin channels are closer to one another so that false coins
with similar measured values are rejected. Narrow and very narrow coin
channels, however, also possess a lower acceptance rate.

In addition, it is possible to allocate coins with different measured values but
identical coin values to different coin channels. This is how the coin validator
can, for example, accept old and new coins of the same type.

However, a coin channel is not only assigned the acceptance band of a coin
type but also other coin information which defines further processing of the
coin after its acceptance: e.g. coin value or sorting information for an
external sorting device.

Since in most cases the manufacturer’s customer-specific programming
does not take up all the coin channels, channels which are still vacant can
be assigned coin types and further information desired at any time using the
WinEMP PC configuration software or PalmEMP2. Existing configurations
can be changed.

The last eight coin channels 25 to 32 (or 9 to 16 with double block data­management, see section "Single or double block data-management" in
this chapter) are intended to be used for the teach mode. In these coin
channels new coin types can also be taught without configuration software,
directly via the lower switching block on the coin validator; i.e. a coin channel
is re-assigned a coin type or also a token (see section "Teach mode" in
Chap. 6 "Operation").

20

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 FUNCTION

Single or double block data-management

At the manufacturer’s company, a customer-specific setting is programmed
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).

If the double block data-management has been configured, the G-13.mft can
data-manage two separately programmed (memory) blocks 0 and 1 (see
label). The 16 coin channels can be assigned to each block with different
coin types (also currencies), sorting information, etc. Only one block can be
active at a time and be used for the coin measurement and for further coin
processing. You can use the upper switching block on the device to select
the desired block (see section "Select memory block" in Chap. 6 "Operation").

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
check whether the inserted coin drops unhindered into the cash-box chute.
A coin signal is not transmitted to the vending machine until the coin has
passed this checking function.

If the accepted coin sensors are continuously covered, e.g. by a coin pile­up, coin acceptance is inhibited.

National Rejectors, Inc. GmbH, Buxtehude

21

FUNCTION G-13.mft MDB/S1

Control for external sorting of accepted coins

In order to be able to guide the accepted coins into the cash-box or, e.g., into
change tubes or hoppers, you can equip the coin validator with the NRI sorting
device or with another sorting device. A larger sorting device can be connected
to the S1 model due to the fact that up to eight sorting ways can be used.

Sorting principle

The sorting gates are activated via the 3-pole JST plug on the rear of the
device (see Fig. 1a and 1b) and via three sorting control lines. Since these
are bidirectional sorting control lines, the coin validator can also receive
signals. If, for example, a connected hopper or change tube is full of coins
and if these units send an appropriate "Full" signal to the coin validator, all
the other coins are directed into the cash-box until the hopper/change tube
is emptied or an amount has been paid out. With the S1 model, this kind of
feedback from an external sorting device can only be provided on sorting
ways that are addressed via a single sorting control line (S1 sorting way 1,
2, 4; see table below).

Which coin type is to be sorted via which of the three sorting control lines is
programmed by the manufacturer according to the customers’ specifications
but it can be changed or re-configured with the WinEMP PC configuration
software or PalmEMP2.

While the coin validator is sorting an accepted coin (= sorting time,
see section "Sorting time of an external sorting device" in this
chapter), it cannot accept any further coins.

With the S1 model, the following sorting control lines are activated for a
specific sorting way:

S1 sorting way Sorting control line "Tube full message"

123

0 (cash-box) – – – no
1 X – – yes
2 – X – yes
3XX–no
4 – – X yes
5X–Xno
6–XXno
7XXXno

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 FUNCTION

Sorting with NRI sorting device

When the optional NRI sorting device
is used (see also section
"Accessories" in Chap. 9 "Technical
data"), the individual coin types can
be distributed regardless of their
dimensions among the three sorting
chutes. Each chute can be defined
as a cash-box chute.

For details on how to connect
the NRI sorting device to
the coin validator, see
Chap. 5 "Starting up".

The following table shows which
sorting control line must be
activated in order to sort coins
into a specific sorting chute:

FUNCTION G-13.mft MDB/S1

Do not accept coin types

If coins are no longer to be accepted for payment at the vending machine,
you can inhibit coin acceptance using either the vending machine control
system or the coin validator.

Inhibit all/individual coin types via vending machine control system

The vending machine can inhibit all coin acceptance. Then the coin validator
no longer accepts coins. However, the vending machine can also inhibit only
specific coin types, e.g., if there is no more change in an external payout
device or a coin type is very frequently replaced by false coins.

For details on how these functions are programmed, please refer to "NAMA
document MDB/ICP 2.0" (www.vending.org) or to the NRI S1 specification
for the G-40 S1, which we will be pleased to place at your disposal on
request.

Inhibit individual coin types/coin type groups on the coin validator

As an alternative to the individual inhibiting of specific coin types using the
vending machine, you can inhibit individual coin types or even groups of coin
types on site using the DIL switches on the coin validator (see section "Inhibit
coin channels" in Chap. 6 "Operation").

If individual coin types are to be inhibited on a long-term basis, you
can use WinEMP or PalmEMP2 to deactivate the respective coin
channels without being required to delete the individual
configuration. This individual configuration remains available and
can be reactivated again later.

G-13.mft MDB/S1 OPERATION

6 Operation

In this chapter you will find out how to:

• Inhibit coin types or their coin channels

• Teach coin types in teach mode

• Select the desired memory block 0 or 1

Inhibit coin channels ...

Depending whether the 32 coin channels are being data-managed in one or,
when divided in 16 coin channels each, in two memory blocks (B-0 and B-1,
see label), the coin types are inhibited differently.

... with double block data-management (B-0 and B-1)

Using the first eight DIL switches of the two switching blocks S1 and S2 on
the rear of the coin validator each of the 16 coin channels or each coin type
assigned to a specific coin channel can be inhibited individually, i.e. this coin
type is not accepted for payment on the vending machine.

The 16 DIL switches inhibit the following coin channels:

Switching block S1
DIL switch off on

1 Coin channel 1 vacant inhibited
2 Coin channel 2 vacant inhibited
3 Coin channel 3 vacant inhibited
4 Coin channel 4 vacant inhibited
5 Coin channel 5 vacant inhibited

OPERATION G-13.mft MDB/S1

Please refer to the label of the device to see which coin type has been
assigned to which coin channel at the factory. However, this assignment
can be changed at any time using the WinEMP PC configuration software
or PalmEMP2.

If all coin types are to be accepted for payment at the vending machine, the
DIL switches S1.1–S1.8 and S2.1–S2.8 of the two switching blocks are in
the lower position on OFF. If you want to inhibit a coin channel, you only need
to move the respective DIL switch toward the top to ON.

Example

(the coin validator is no longer supposed to accept the coin(s) assigned to coin
channels 3 and 10, which means that coin channels 3 and 10 must be
inhibited)

With the DIL switches in these positions, the coin validator no longer
accepts the coin type(s) assigned to coin channels 3 and 10!

If a normal coin channel and a narrow coin channel have been
programmed on the coin validator for one coin type, the normal coin
channel must be inhibited as described above in order to activate
the narrow coin channel. If both channels are activated, the wider
acceptance band of the normal coin channel is used.
If a coin type is to be inhibited, both coin channels must be
inhibited.

32

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 OPERATION

... with single block data-management

Coin channels can be inhibited using the first eight DIL switches S1.1–S1.8
of the upper switching block on the rear of the device. To do this the DIL
switches are assigned a coin channel randomly. Several coin channels can
also be assigned to one switch. This switch will then inhibit a coin group (e.g.
all coin channels of a currency, all coin channels of a coin type (normal and
narrow coin channels)).

The assignment of DIL switches to coin type/coin group is programmed at
the factory on a customer-specific basis. However, this setting can be
changed with the WinEMP PC configuration software or PalmEMP2.

If all coin types assigned to the DIL switches are to be accepted for payment
at the vending machine, the DIL switches must be in the lower position (on
OFF).

If you want to inhibit a coin channel, you only need to move the respective DIL
switch toward the top to ON.

The following examples are designed to illustrate the procedure using the
label. The label shows the manufacturer’s assignment of coin type/coin
group.

Any coin types or tokens that may have been taught in coin
channels 25 to 32 are inhibited using the DIL switches of the lower
switching block S2 in the assignment according to which they were
taught (see section "Teach mode" in this chapter).

National Rejectors, Inc. GmbH, Buxtehude

33

OPERATION G-13.mft MDB/S1

Example – Inhibit a currency as coin group

(the coin validator must only accept euros and no longer the British currency)

With this setting the coin validator only accepts euros.

Example – Activate narrow acceptance bands/coin channels as coin group

(the coin validator must accept the 1-euro coin and the British 1-pound coin in the
narrow acceptance band and not in the normal one, i.e. it must inhibit the normal
acceptance band)

With this setting the coin validator accepts coins in the narrow coin channel and
not in the normal one.

Example – Inhibit single coin type

(the coin validator must no longer accept the 2-euro coin or the British 2-pound coin)

With this setting the coin validator no longer accepts the 2-euro coin or the British
2-pound coin.

At a coin validator with the label described above, it would also be
possible to inhibit the euro currency via DIL switch S1.4.

34

With the aid of several DIL switches more than one coin type or coin
group can be inhibited simultaneously.

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 OPERATION

Teach mode

Coin channels can also be taught directly without configuration software via
the switching block on the coin validator, i.e. a coin channel is reassigned a
coin type or even a token without having to remove the coin validator from
the vending machine. You can also widen the acceptance band for the
selected coin channel so that the rejection of genuine coins is reduced. For
the teaching procedure, coin channels 9 to 16 of the activated memory block
are available with double block data-management and coin channels 25 to
32 with single block data-management (see also section "Single or double
block data-management" in Chap. 4 "Function").

OPERATION G-13.mft MDB/S1

Teach coin channels

To assign a coin type to a new coin channel, please proceed as follows:

If you want to use the lower switching block to inhibit individual
coins, remember the current switch settings so that you can restore
them easily for the normal operating mode at the end.

1 Set all DIL switches 1–10 of the lower

switching block toward the bottom to OFF.

2 Set DIL switch S2.9 toward the top to ON.

Now the device is in teach mode to teach
the coin channels.

3 Release the coin channel to be taught

(9–16 or 25–32, here: 11 or 27) by setting
the appropriate DIL switch (S2.1–8, here:
S2.3) toward the top to ON.

4 Insert at least 10 coins of the new coin type/token into the coin

validator or vending machine.
After the 10
operated once (solenoid attraction sound). Additional coins can be
inserted.

th

coin has been inserted, the acceptance gate is

Now you can save the measured values generated by the inserted coins in
either a normal (a) or a wide (b) acceptance band. A wide acceptance band
is only an appropriate choice when you only have a limited selection of coins
at your disposal for the purpose of teaching tokens and would still like to
program greater tolerance limits.

To save with the normal acceptance band:

5a) Set DIL switch S2.9 toward the bottom

to OFF.
Successful saving is signalled by the
acceptance gate attracting once, an
error when saving is indicated by the acceptance gate attracting
twice, if, for example, the acceptance band of the coins inserted and
an acceptance band of an already programmed coin channel overlap.

To abort the operation, first set the DIL switch of the respective coin
channel (here: S2.3) and then DIL switch S2.9 toward the bottom to
OFF.

36

National Rejectors, Inc. GmbH, Buxtehude

G-13.mft MDB/S1 OPERATION

To save with a wide acceptance band:

5b) Set DIL switch S2.10 toward the top to

ON.
The acceptance band has been
widened.

Now you can set DIL switch S2.9
toward the bottom to OFF.
Successful saving is signalled by the
acceptance gate attracting once, an
error when saving is indicated by the acceptance gate attracting
twice, if, for example, the acceptance band of the coins inserted and
an acceptance band of an already programmed coin channel overlap.

To abort the operation, first set the DIL switch of the respective coin
channel (here: S2.3) as well as DIL switch S2.10 and then DIL
switch S2.9 toward the bottom to OFF.

6 Set DIL switch S2.1–8 (here: S2.3) and S2.10, if necessary, for the nor-

mal operating mode (see section "Inhibit coin channels" in this chapter).

The new coin type/token will now be accepted for payment by the coin
validator.

The DIL switches of the lower switching block S2 can be used to
inhibit the taught coins or tokens in the assignment according to
which they have been taught.

Select memory block (only for double block data-management)

If the 32 coin channels, divided in 16 coins channels each, are data-managed
in two (memory) blocks (B-0 and B-1, see label), these (memory) blocks are
programmed separately from one another by the manufacturer on a customer­specific basis. The data of the two blocks 0 and 1 differ when they are being used
in the device, e.g. by the acceptance of different currencies, such as national
currency and euro. Only one block can be active at a time and be used for the
coin measurement and for further coin processing.

If the coin validator is to access the other memory block and, e.g., accept euro
coins instead of national currency coins, the correct block can be selected using
the upper switching block.

Set DIL switch S1.10 of the upper switching block downward to OFF to select
memory block 0 and upward to ON to select memory block 1.

8 Which functions can be set using

WinEMP/PalmEMP2?

The software WinEMP or PalmEMP2 is used for diagnostics purposes and
configuration of NRI coin validators as well as for the purpose of updating the
data blocks in the device memory.

WinEMP is PC software and part of a programming station for the workshop.
For more information, please see the section "Accessories" in Chap. 9
"Technical data".

PalmEMP2 is software stored on a Palm handheld as additional application. If
the Palm handheld is linked to the coin validator via an NRI dongle (see section
"Accessories" in Chap. 9 "Technical data"), the G-13.mft can be directly
configured on site inside the machine.

Both programs identify the connected coin validator and the device’s own
data and present them on the screen of your PC or on the Palm handheld
display.

The device functions listed below can be set using WinEMP/PalmEMP2
(see separate software instructions).

• Attraction duration

• Sorting time

• Assignment

– coin value – coin type
– DIL switch – coin type (internal inhibit, only with single block data-

management)

– sorting control line/sorting way – coin type

• Coin acceptance band after the insertion of

– genuine coins
– false coins

• Teach coin channels

• Deactivate coin channels individually using coin validator software

• Data block update for current coin information

For the data block update, an additional module must be ordered in
addition to the WinEMP software’s basic module (see section
"Accessories" in Chap. 9 "Technical data").
If you wish to perform data block updates using the Palm handheld,
you need the WinEMP software with the PalmEMP download rights,
which are stored on the WinEMP chip card (see section
"Accessories" in Chap. 9 "Technical data").

G-13.mft MDB/S1 TECHNICAL DATA

Configuration software

To be able to react as quickly as possible to new false coins, in the workshop
or on site, and enable you to make your individual adjustments, the coin
validator can be connected to:

• The NRI PC programming station consisting of
– Configuration and diagnostics software "WinEMP", including card

reader und chip card (ordering code: 20119 for basic module and
20169 for additional module)

– Tester G-19.0641 (ordering code 12922)

• The NRI Palm application "PalmEMP2", which is available on the NRI
homepage. To be able to connect a Palm handheld m125 to the coin
validator, you need a dongle with the ordering code 23760; for an m105,
a dongle with the ordering code 23761. If you want to perform data block
downloads with the help of a Palm handheld, you need the WinEMP
software (see above) with PalmEMP2 download rights (ordering code

23649), which are saved on the WinEMP chip card.

You can also use a 9-pole D-SUB plug (ordering code 23764) to
connect the Palm handheld via the universal dongle. However, the
Palm handheld must be equipped with an interface that can be
connected to the serial HotSync cable (available with PalmTM).
For further details about the individual PalmEMP2 dongles, please
refer to the NRI homepage (www.nri.de).

For details on which settings can be made with the help of WinEMP and
PalmEMP2, please see Chap. 8 "Which functions can be set using WinEMP/
PalmEMP2?" For details on how to carry out these settings, please refer to
the separate software instructions.

G-13.mft MDB/S1 GLOSSARY

Glossary

Acceptance band A range of acceptable measured values of one → coin type

(with specific → coin properties) defined by an upper and
lower limit value.

Acceptance gate The acceptance gate diverts the inserted coins into the

acceptance or return area of the coin validator.

Accepted coin sensors The accepted coin sensors are positioned in front of the

cash-box coin outlet of the coin validator and check whether
accepted coins fall unhindered into the cash-box chute.

Attraction duration The attraction duration is used to specify the period of time for

which the solenoid is to attract the → acceptance gate in
order to guide the accepted coins to the cash-box or an
external sorting device.

Block → Memory block
Channel → Coin channel
Coin acceptance band → Acceptance band
Coin channel Coin channels are used to describe → coin types using their

different → coin properties (alloy, size, etc.). The required
coin properties of a coin type are defined in →acceptance
bands which are assigned to the coin channels together with
other coin information for further processing along.

Coin properties Coin properties are measured when a coin is inserted into the

coin validator. These are e.g. material, thickness, volume,
minting, diameter, mass, hardness, etc.

Coin type One coin type includes all coins for which the → coin

properties agree.

Coin value The value of a → coin type that is transmitted from the coin

validator to the machine.

Data block update When updating a data block (set) (2 data blocks) using

WinEMP or PalmEMP2, the data blocks for the connected
coin validators are loaded quickly and easily from the internal
hard disk of your PC into the coin validator. By doing this, a
new data block is loaded into → memory block 0 (and
memory block 1). The new data blocks contain different
configurations of → coin channel data, e.g. current limit
values of the → acceptance bands for a currency or new coin
or sorting information.

GLOSSARY G-13.mft MDB/S1

ECV Electronic Coin Validator
MDB Multi Drop Bus. The abbreviation defines a serial interface

specification for an internal communication protocol for
vending machines.
For further information on the MDB interface, please refer to
"NAMA document MDB/ICP 2.0" (www.vending.org).

Memory block Memory of the coin validator. At the manufacturer’s company,

a customer-specific setting is programmed to determine
whether the 32 → coin channels of the G-13.mft are to be
data-managed in one memory block (single block data­management) or, when divided into 16 channels each, in two
memory blocks (double block data-management). Two
(memory) blocks 0 and 1 can be used to data-manage two
independent configurations of coin channel data (e.g. two
currencies). However, for coin validator operation, only one
memory block with 16 channels can be active at a time; the
other block is inhibited.
The memory block(s) can be updated using WinEMP or
PalmEMP2 (→ data block download).

S1 This abbreviation defines a serial, NRI-specified and

→ MDB-based interface to the vending machine.
You will find detailed information on the serial S1 interface in
the NRI S1 specification for the G-40 S1, which we will be
pleased to place at your disposal upon your request.

Sorting control line To sort the cash coins with an external sorting device, the

coin validator has three sorting control lines, which can be
used to activate three sorting ways with the MDB model and
up to eight sorting ways with the S1 model.

Sorting gate The sorting gates are activated in the coin validator depending

on the run time of accepted coins and direct the coins to be
sorted into the return area or coin outlet towards the cash-box
or external sorting device.

Sorting time The sorting time specifies the switching times of an external

sorting device.

String sensor The coin validator’s optional sensor recognizes a coin inserted

with a piece of string attached to it. The coin is not accepted
for payment.

G-13.mft MDB/S1 GLOSSARY

Switching blocks The two switching blocks are located on the rear of the coin

validator and incorporate 10 DIL switches each. Each switch
has a specific function, e.g. inhibiting individual or grouped →
coin channels.

Teach mode In the teach mode, the last eight → coin channels can be

assigned new coin types or tokens on site at the vending
machine, which means that these newly configured coins
are accepted in the respective coin channel.

Token Token are accepted for payment at machines instead of

coins in a currency.
