1 Introduction

The REA M V-2D is an instrument for verifying the quality of printed matrix codes and

1D codes. It is a stationary piece of equipment that must be connected to a PC over

an Ethernet network. The PC runs the supplied analysis software and device drivers,

and is used to display the verification reports.

In contrast to barcode and matrix code scanners, the REA M V-2D is a measuring

instrument that works on optical principles. All measuring instruments must be

adjusted and calibrated regularly (test equipment monitoring). These adjustments and

test equipment monitoring can be performed by the operator.

A verification result may point to quality defects. In practice, these quality defects

may range from barely noticeable to a total failure in terms of legibility – depending

on the application and the extent of the defects. The course of action chosen as a

response to quality defects is highly dependent on the corresponding application

conditions and the code readers used.

Scanners are typically unsuited to quality control work. Their task is to capture codes

as efficiently as possible. Any attempt to use a scanner to perform quality control

work merely provides information about the ability of the scanner used to read bad

codes.

If various types of scanner are used, the decoding results may show differences. For

quality control work involving printed codes, the focus is on the code's quality

properties and not the ability of the scanner to compensate for defects in code

representation.

ISO/IEC 15415 and ISO/IEC 15416 are applied to grade the verification results. The

grading is tabulated below:

activation code, which must be entered in TranWin32.

The scope of delivery for re-ordered software options consists of a data medium, a

handbook and an activation code.

3 REA MLV-2D models

All REA M V-2D models share the same basic design. Any changes to this design

result from the various camera modules and the various base plate configurations.

The REA M V-2D devices supplied with 90° coaxial lighting include an additional power

adapter and the built-in coaxial lighting in the scope of delivery. The coaxial lighting

can be removed, to also enable the REA M V-2D to be used with the normal standard

45° and 10° lighting. 90° coaxial lightning must be ordered for a new device and

cannot be added later.

4 Commissioning

This chapter describes the installation and preparation work to be performed before

using the REA M V-2D.

4.1 Operation and transportation

Humidity, cold and heat as well as mechanical shocks and falls can cause damage –

possibly irreparable – to the measuring chamber cover and other mechanical or

electronic parts. If the device has been damaged in this way and continues to provide

measurement results, there is a serious risk of these results being incorrect or

deviating too far from the correct values.

Following transportation, please consult sections 4.2and 4.3.

The REA M V-2D is delivered in a case or in a cardboard box with appropriate foam

padding. This packaging should be retained for possible later transportation. If the

REA M V-2D is shipped without the original packaging, it should be packaged with

enough padding to ensure that the device cannot move about in the shipping box.

4.2 etup

The REA M V-2D should be set up on a flat-topped table. Measurements shall not be

affected by ambient light sources. Accordingly, diffuse lighting is required to illuminate

the workplace. Direct light from sunlight or spotlights is forbidden. The film on the

display serves to protect the surface and can be removed. The REA M V-2D is

section 4.6.

The REA M V-2D has been designed for normal office, lab and manufacturing

environments. Operation in environments requiring explosion protection (e.g.) or

similar is unsupported and the operator takes sole responsibility for such use.

4.3 Temperature changes

If the REA M V-2D is subjected to temperature changes (e.g. when it is set up in

heated rooms after transportation in winter), its optical parts may fog up. In such

cases, about 15 minutes waiting time is required to warm up before using the REA

M V-2D.

4.4 Power supply

Power is supplied to the M V-2D device via its network cable. This type of power

supply is called Power over Ethernet (PoE). The power adapter provided only supplies

electrical power to a connected device if this device is also designed to operate by

using this kind of supply voltage. Nevertheless it is recommended never to connect

non-PoE-enabled network devices to the power adapters OUT port. A second cable or

additional, separate power adapter is not required. Apart from their improved

flexibility, the network cables supplied are standard off-the-shelf parts

(CaT 5e or better)

REA VERIFIER

Page 9 of 98

4.5 ystem requirements

To supply power to the device, a mains connection rated at 100–240 V AC and 50–60

Hz is required.

The Windows application TransWin32 requires a standard off-the-shelf computer

running the Microsoft Windows OS:

- At least Windows 7 (32-bit) or later. Note: 32-bit installs are unusual with

Windows 7 and Windows 8. It is therefore strongly recommended to use only

the 64-bit Windows versions.

- Microsoft .NET Framework Version 4 or later (if possible, the current Version

4.5.2 or later)

- One or (optionally) two Ethernet network interfaces

(2 Ethernet network interfaces are recommended – at least 1 Gbit/s, auto-

detect between normal and crossover)

- RAM: Ensure the minimum requirements of the operating system used have

been met. Typically, you should aim for 4 GB or more.

- Hard disk: Ensure the minimum requirements of the operating system used

have been met.

- CPU: Ensure the minimum requirements of the operating system used have

been met (a slow CPU increases the wait time).

- Mouse (with mouse wheel)/keyboard (supplementary touchscreen as required)

- Monitor/graphics – non-glare screen, min. 48 cm (19"), resolution of at least

1280 x 1024 pixels, colour

- Optional: PDF program for creating verification reports as PDF files (as a virtual

printer)

- PDF display program

- Firewall: the firewall must allow network traffic to/from the REA M V-2D.

The REA software TransWin32 is a single-user application. The licence is linked to the

REA verifier and not to the PC installation. The software does not need a dongle and

multiple copies can be installed if required.

Running the software on a server is untested and is not guaranteed to work. As long

as the server offers the REA program TransWin32 an environment that responds to

the program as a single-user workstation would, server installs should work properly

(virtual environment, sandbox, etc.).

Installation on Windows XP will not work as the software contains program

components that require functionality offered only by later versions of the operating

system.

While the minimum computer requirements are adequate, we recommend

using the configuration that the operating system used also specifies as its

recommended configuration.

REA VERIFIER

Page 10 of 98

4.6 Connecting up

The REA M V-2D is supplied with two identical network cables.

Figure: Network cables

The REA M V-2D is connected to the PoE power adapter using one of the two Ethernet

cables. The socket labelled "P+D/OUT" on the power adapter is used to connect it to

the device. The device will not be powered if connected to the other "Data/In" socket.

The second network cable is used to connect the PoE power adapter's "Data/In"

socket to the computer (directly or indirectly).

The left-hand picture illustrates the connection of the

Data/In socket to the network system (represented here

by the Ethernet switch).

For connecting to mains power, the power adapter has a

socket for an IEC cord plug. This mains cable is supplied

to meet the national standard.

The socket type is C14 (IEC 60320). The plug type is

C13.

Figure: Socket, IEC cord plug

Supplying power via PoE is characterised by the power adapter first checking whether

or not a connected device is designed for use with a PoE power supply. While this is

being checked, the device cannot yet be turned on. With the REA M V-2D, this delay

will typically be barely noticeable.

REA VERIFIER

Page 11 of 98

CAUTION: REA offers a fully-featured range of code verifier devices. For all of

these devices, power is supplied by PoE power adapters. The REA MLV-2D

requires the 15 W POI-2002 adapter. The other devices use the 30 W POI-

3000 adapter (or POI-3002/POI-3004 adapters). If these power adapters

become mixed-up, then the PoE power supply may stop working in some

cases. Accordingly, power adapters shall not be mixed up.

The following list offers a brief summary of typical connection options:

• The PC and M V-2D are each connected to a separate network access port in

the room (DHCP mode)

• The PC and M V-2D are connected directly (Zeroconf or fixed IP address)

• The PC and M V-2D are connected using an Ethernet switch (Zeroconf or fixed

IP address)

• The PC and M V-2D are connected using an Ethernet switch, and the Ethernet

switch has a connection to the network (DHCP mode).

4.6.1 Dedicated Ethernet port

The PC has one or a second network port, which is reserved exclusively for the

operation of the verifier. The "Data/IN" socket on the power adapter is connected

directly to this port with a cable. With this configuration, PCs that only have one

network interface can no longer be integrated into the corporate network. In this case

it is recommended to use a second network card (in the simplest case, wireless via

Wi-Fi).

4.6.2 Network mode

The PC is permanently connected to a company network. The REA M V-2D is

connected using its power supply "Data/IN" port and an available and connected

(patched) network socket. The (DHCP) server in the network assigns the network

addresses automatically. When the company network is experiencing heavy network

traffic, faults (the device shows network errors) may occur during operation. If these

faults become too frequent, the network will need to be segmented by network

administrators or the REA M V-2D will need to be connected to the computer using a

separate network port (see the previous section).

4.6.3 witch-based PoE

Operation on an Ethernet switch, which provides the PoE power supply instead of the

supplied power adapter, is also possible. A port is required that is capable of providing

30 W of power. The operator bears responsibility for this operating mode – it has not

been tested by the manufacturer. As PoE is an industry standard for power supplies, it

will not generally cause problems unless a PoE switch becomes overloaded by

handling too many consumers.

REA VERIFIER

Page 12 of 98

4.6.4 MAC addresses

Every network-enabled device is issued with a MAC address by the manufacturer. The

MAC address is stated on the product label. Some network environments are

configured so that only known devices are given access. In this case, the IT

department is to be notified about the MAC address so it can be authorised.

4.6.5 Firewall and network type

If a firewall is being used, it must be configured so that it permits network traffic

between the PC and the REA M V-2D device. Security policies are usually queried

during initial system start-up.

When the operating system identifies a new network, the operator is asked whether

this is a public network. This must be answered in the negative (public networks

include Wi-Fi networks at rail stations, airports, etc. , never an operation environment

for the REA Verifier).

If particularly strict security policies apply within a company or if the network typically

experiences heavy traffic, REA recommends using a second Ethernet port on a PC

reserved for exclusive use with the REA M V-2D.

The data medium provided contains a document that describes the network

integration in detail and also specifies which ports are used. This document should

also be consulted for difficult installations.

4.6.6 Firewall and network ports

Several modules need to be installed (see section 4.7.2). Communication between

modules is achieved using networking mechanisms (sockets and ports). The ports

used are listed below and may need to be opened in the firewall configuration:

Transwin32.exe

Port: 23945

ServiceTool.exe

Port: 23947

MorpheusHost.exe

Port: 23946

M V_Control_PC.exe

Port: 1006

M V

2D_Control_PC.exe

Port: 10051

readb.exe (Article Database)

n/a

The firewall must not block any of the programs listed in the table, since the

applications will otherwise cease to work properly.

4.6.7 Gateway mode

The REA M V-2D uses the TCP/IP communications protocol. UDP is used for device

detection. UDP traffic is not typically routed over a gateway. In this scenario,

connection handshaking will not work. For such a case, in the REA TransWin32

program menu Configure -> Options -> Devices the device type HOME -> Device

search should be deleted. Instead, enter a ocal Device. Specification of the full serial

number is mandatory for this configuration option. The IP address is configured as

fixed. During operation, the REA M V-2D must be assigned a fixed IP address from

the DHCP server (always the same). The M V-2D can also be configured to use a fixed

REA VERIFIER

Page 13 of 98

IP address (not recommended but mandatory if a fixed address is not assigned via

DHCP). The REA M V-2D sister model, REA VeriCube, uses GigE Vision. This was

primarily developed for a direct connection between the computer and the camera.

Running GigE Vision over a gateway is not supported and will not work properly.

4.6.8 Fixed IP addresses

Some environments either advocate or require the assignment of fixed IP addresses.

This typically involves manual configuration of both the PC and the verifier. This kind

of configuration limits application flexibility. The use of a DHCP server is the

recommended configuration. The DHCP server manages a list of devices identified by

their MAC addresses. The administrator can configure the server to assign always the

same (fixed) IP address to a specific machine.

4.6.9 DHCP

DHCP mode: the PC and REA M V-2D are on the company network and request their

network settings from the DHCP server. This mode is active in the factory settings.

4.6.10 Zero-configuration networking

Zero-configuration networking is also described as "Zeroconf mode". The PC and REA

M V-2D use a direct connection. Since no server can be reached (owing to the direct,

point-to-point connection), zero-configuration networking is used automatically as the

system setting (automatic fall back). This mode is active in the factory settings by

activating automatic network configuration. The PC's network adapter reports the

status " imited or no connectivity".

The machine enters Zeroconf mode automatically after a wait time of about 1–2

minutes.

During the wait time, the PC displays a network icon with a moving yellow

point on the status bar (differs slightly according to the Windows version).

In this state, no connection is possible.

Once automatic configuration is complete, the network icon is displayed with

a yellow exclamation mark. Communication is now possible. The exact

representation will also differ depending on the version of Windows installed.

REA VERIFIER

Page 14 of 98

4.6.11 Network settings at the terminal

The settings for automatic configuration (selection: DHCP ON) or the fixed IP address

can also be configured on the device itself.

The settings menu is called up by using the Setup key under Settings and then

"Network parameters".

Figure: Settings menu and device configuration Figure: Network configuration

The equivalent setting in the TransWin32 Windows application is reached from the

menu "Configuration -> Other -> Device system…".

REA VERIFIER

Page 15 of 98

4.7 oftware

The REA TransWin32 software is required for operation. Only one REA M V-2D can be

used per computer. Other REA verifiers can be installed and used on this computer –

just not a second REA M V-2D device. The licence for the REA TransWin32 software is

linked to the REA verifier and not to the PC installation. Accordingly, TransWin32 can

be installed on multiple PCs in parallel. The REA TransWin32 software is always

included in the REA M V-2D scope of delivery.

REA TransWin32 is designed solely for device configuration, as well as the display and

management of verification reports. The actual grading of the code measured is

performed in a separate device service (Verifier Device Server). The device service is

started (and terminated) automatically with the TransWin32 software.

4.7.1 oftware installation

Prior to the actual installation, the Microsoft .NET Framework must be installed. The

REA installation checks whether .NET is present and cancels the operation if it is not

installed. On the Microsoft website, there is a search function in the download section.

If searching for ".NET offline", the website suggests the .NET installation package

(Version 4.5.2, as of July 2014). As of this writing (summer 2015), the latest version

of the .NET Framework is offered by Microsoft Update automatically.

Once the system requirements have been met, the TransWin32 program must then be

installed. To do so, start "Setup.exe". Depending on the version, either the

TransWin32 install is offered directly or first the TransWin32 button and then "Install

TransWin32".

Administrator rights are required for installation. For day-to-day use, normal user

rights are sufficient. If the software is installed for all users, the "All Users" folder is

used. This general user directory is by default accessible to all users. In case it is not

accessible the installation won’t work.

The safest and least complicated option when installing turns the user account into an

admin account for the installation. Since the installation is performed for this user

only, only the Documents folder of the logged-in user is used. If the installation is

being performed with the "Run as administrator" option, it will use the administrator

account itself and not the user's account. In this case, the software should be installed

for all users and care should be taken to ensure that all users have read/write

permissions for the "All Users" folder.

In the event of communications between the Windows software TransWin32 and the

REA M V-2D experiencing dropped connections or error messages such as sensor

errors, two courses of action can be taken:

1. Both the PC and the REA M V-2D can be connected to a small local switch.

2. On the PC, the REA M V-2D requires a dedicated Ethernet port used exclusively

by this device.

If an older version of the TransWin32 software was installed previously, this will be

removed before installation of the new version. In some cases, it will be necessary to

remove the old version manually by using "Programs" from the Windows control

panel.

These two software options should be installed only when these software options have

been bought together with the REA verifier device.

The system then asks the user to specify the type of install:

If the programs are installed for all users, the "All Users" folder is used to store files

and data. Users need read and write permissions for this folder. If very strict security

policies are in place, then access to the All Users folder may not have been granted to

all users.

If the programs are "...installed only for me", the data folder of the logged-in user is

used as the folder for files and data (except if setup was run as an administrator,

when the admin's document folder is used – in this case, always select "...for all

users"). This variant will have to be chosen if directory access has not been granted to

all users.

Restoring an old configuration backup is possible only for the REA VeriCube verifier

model. If an old dataset with calibrated data is available, this is re-imported into the

new installation if the configuration backup option was checked while uninstalling the

old version. The REA M V-2D stores this data on the device itself and therefore does

need such a function.

In the next step, installation paths are displayed and can be changed if necessary.

The programs are installed into the Programs (or Program Files) folder. The suffix

"x86" indicates that it is a 32-bit program (not 64-bit).

The path C:\ProgramData is the storage location for installation- or program-relevant

data and is normally invisible to system end-users. This path should be changed only

if there are compelling administrative reasons for doing so. Actual user data is always

stored in the user's Documents folder or in the All Users folder.

A final check can be made before installation proceeds.

Note: if the install is cancelled at this point, the old version will already have been

removed and the new one will not be installed.

The software is then installed and the install process is displayed in the window with a

progress bar.
