vend

transactions

and

translate

them

into

appropriate

DEX

data

elements.

In

the

second

mode,

the

AMC

is

con?gured

to

act

as

an

active

audit

device

When

connected

to

the

MDB

interface

29

to

Which

VMCs

can

directly

transmit

audit

data.

Currently

there

is

an

Audit

Device

(address

18H)

de?ned

in

the

NAMA

MDB/ICP

speci?cation. In

addition,

a

propri

etary

MDB

based

audit

device

has

been

produced

for a

speci?c

company.

It

resides

on

the

MDB

bus

as

address

188H

and

neW

controllers

for

that

company

support

it.

In

addition

to

dedicated

messages

to

the

proprietary

audit

device,

the

neW

MDB

File

Transport

Layer

is

also

implemented

Which

provides

for

high

level,

bi-directional

data

transfers

across

the

MDB

bus

to

the

VMC

or

other

peripherals

that

support

FTL.

The

Executive

interface

30

is

a

four

(4)

Wire

current

loop

interface

used

by

coin

mechanisms

and

card

readers

to

communicate

With

vending

machines.

The

inter

face

is

primarily

used

in

Europe

and

other

Western

countries

outside

the

US.

It

is

based

on

a

specialiZed

bi-directional,

9600 baud

coded

message

structure.

[0030]

The

AMC

10

is

able

to

operate

in

tWo

modes

When

connected

to

the

Executive

interface.

In

one

mode,

it

moni

tors

the

Executive

message

traf?c.

In

this

mode,

the

AMC

is

able

to

interpret

the

messages

and

collect

virtually

all

credit

and

vend

transactions

and

translate

them

into

appropriate

DEX

data

elements.

In

the

second

mode,

the

AMC

is

con?gured

to

act

as

an

active

audit

device

on

the

Executive

interface

32.

Various

coin

mechanisms

and/or

card

readers

recogniZe

the

existence

of

an

audit

module

and

transmit

transaction

information.

The

AMC

receives

the

Executive

messages

and

translates

them

into

appropriate

DEX

data

elements.

[0031]

A

pair

of

One-Wire

interfaces

(actually

2

Wires

including

ground)

are

unique

interfaces

used

to

access

devices

manufactured

by

the

DALLAS

Semiconductor

Company.

One

interface

34

is

used

to

read/store

information

to

a

Touch

Memory

for

quick

setup

and/or

time

and

date.

The

second

interface

36

is

used

to

monitor

the

temperature

of

the

machine

to

detect

machine

malfunctions

Which

could

result

in

potential

product

spoilage.

Alimit

(alarm)

condition

can

be

set

to

be

logged

as

an

event.

[0032]

The

Micromech

(MCSOOO)

interface

38

is

a

tWelve

(12) or

?fteen

(15)

Wire

interface

used

by

coin

mechanisms

to

communicate

With

vending

machines.

The

interface

38

is

primarily

used

in

the

US

and

is

based

on

a

specialiZed

uni-directional,

600

baud

coded

message

structure

With

additional

bi-directional

control

signals.

Although

the

coin

mechanisms

can

operate

either

from

120

VAC

(12

pin)

or

24

VAC

(15

pin),

the

AMC

monitors

only

the

loW

voltage

(5

VDC)

signals

used

for

communications

and

control.

[0033]

The

Pulse/Serial

Bill

Validator

interface

40

is

a

multi-Wire

credit

pulse

type

interface

or

specialiZed

unidi

rectional,

600

baud

coded

message

structure

With

additional

bi-directional

control

signals

that

is

monitored

to

determine

the

cash

amount

of

inserted

bills.

Typically,

it

Will

be used

in

conjunction

With

the

Micromech

interface

to

accumulate

a

complete

accounting

of

the

cash

transactions.

[0034]

The

ACD

interface

42

is

a

three

(3)

Wire

interface

used

by

coin

mechanisms

to

transmit

cash

information.

It

is

based

on

a

specialiZed

unidirectional,

1200

baud

coded

message

structure

sent

as

three

double

byte

packets

(dou

blets).

The

AMC

monitors

the

ACD

messages.

[0035]

To

alloW

the

AMC

to

detect

and/or

force

machine

functions,

the

controller

incorporates four

(4)

general

pur

pose

inputs

and

tWo

(2)

general

purpose

“open

collector”

outputs

44.

The

inputs

are

typically

set

to

be

logged

as

machine

events.

Inputs

three

and

four

can

also

be used

With

an

optional

Optical

Isolator

Module

to

monitor

either (or

both)

of

a

cash

counter

and

a credit

line.

[0036]

Regarding

the

cash

counter,

the

coin

mechanism

transmits

a credit

pulse

to

indicate

the

cash

amount

of

vends.

Sent

after

a

vend,

each

pulse

translates into a

monetary

unit

(one

pulse

equals

5

cents).

Concerning

the

credit

line,

the

mechanism

transmits

an

actual

vend

relay

output

Which

is

used

to

initiate

a

vend.

Each

pulse

translates into a

single

vend

count.

[0037]

The

LMM/MMM

and

DLMM/DMMM

interface

46

is

used

to

connect

to

a

Linear

Motor

Monitor

(LMM)

or

to

a

Matrix

Motor

Monitor

(MMM),

or

to

a

Direct

Linear

Motor

Monitor

(DLMM),

or

to

a

Direct

Matrix

Motor

Monitor

(DMMM),

Which

are

individual

AMC

sub-modules

that

are

used

to

monitor

vending

machine

motors

and

various

other

vending

machine

interfaces.

The

LMM

and

MMM

are

individual

AMC

sub-modules

Which

are

used

to

monitor

vending

machine

motors

and

incorporate

a

micro

processor

Which

scans

motor

inputs

and

sends

the

informa

tion

to

the

AMC

for

further

processing.

The

LMM

and

MMM

can

be

used

if

the

AMC

does

not

monitor

the

Micromech

(MCSOOO)

or

Pulse

Bill

Validator

interfaces

directly.

The

LMM

is

designed

for

higher

voltage

(120

VAC)

linear

motors and

the

MMM

is

designed

for

loWer

voltage

(24

VDC)

matrixed

motors.

AEuropean

version

of

the

LMM

is

designed

for

240

VAC

linear

motors.

The

AMC

interfaces

With both

via

a

serial,

1200

baud,

four

(4)

Wire,

optically

isolated

bus.

Information

received

from

the

devices

is

trans

lated

into

appropriate

DEX

data

elements

by

the

AMC.

[0038]

The

Direct

Linear

Motor

Monitor

(DLMM)

and

the

Direct

Matrix

Motor

Monitor

(DMMM)

are

individual

AMC

sub-modules

Which

are

used

to

monitor

vending

machine

motors

directly

from

the

AMC.

These

devices

can

be

used

if

the

AMC

directly

monitors

the

Micromech

(MCSOOO)

or

Pulse

Bill

Validator

interfaces.

The

DLMM

is

designed

for

higher

voltage

(120

VAC)

linear

motors

and

the

DMMM

is

designed

for

loWer

voltage

(24

VDC)

matrixed

motors.

A

European

version

of

the

DLMM

may

be

designed

for

240

VAC

linear

motors.

The

AMC

interfaces

directly

With both

via

a

“bit

banged”,

three

(3)

Wire

signal

bus.

Information

received

from

the

monitors

is

translated

into

appropriate

DEX

data

elements

by

the

AMC.

is

provided

to

to

manually

provide

to

the

AMC.

An

example

Would

be

a

“Fill

Which

Would

be

pressed

When

the

machine

is

completely

This

prompts

the

[0040]

In

an

implementation;

the

Audit

Monitor

Control

ler

10

transmits

its

monitored

and

collected

data via

the

industry

standard

EVA-DTS

DEXIUCS

protocol.

A

9600

interface

50

is

based

on

the

0

5

VDC

RS232C

signals

as

de?ned

in

the

EVA-DTS.

Although

the

AMC

normally

takes

the

role as a

SLAVE

during

the

?rst

DEX

handshake,

it

can

be

optionally

be

con?gured

to
