The imago G1 electronic shelf label family offers high-quality display options, operating with
a replaceable battery and thus working with any external power supply. Thanks to the
perfect readability of the e-Ink displays and our outstanding wireless data transmission
technology you can implement all your sales, marketing, and logistic strategies.
The AP-2010 by imagotag is the communication center in the store that transmits price
information to the labels. Up to 10 000 labels can be managed per access point and the selforganizing network allows automatic roaming of labels without manual handling. The high
transmission rate of the 2.4 GHz wireless technology and the intelligent task scheduling
enables fast and secure updates on imago G1 labels of all sizes.
The access point communicates with the electronic shelf labels with radio frequency on the
2.4 GHz ISM band with a proprietary protocol developed by imagotag. It supports 11
selectable channels.
: The ESL server is a Java software that is required to manage the imagotag
access points and electronic shelf labels. The ESL server may be executed as a background
service on a Windows or Linux machine in the store and does not provide a graphical user
interface.
: The ESL client is also Java based software. It’s a graphical user interface (GUI)
for monitoring and for the configuration of the ESL server. The ESL client connects to the ESL
server. The server may be installed on the same machine or any other machine that is
accessible over the network.
: To render images from article records on the ESL server, the layout must
be predefined in a template file. During the rendering process the data will be inserted into
the fields reserved to hold this data. Templates are based on web standards (XML, XSL,
XPath, CSS) and an proprietary XML based markup language. Therefor an editor to create
and edit template files with live preview based on example records is also on the imagotag
USB stick.

Figure 3 - Smart Box Inside
As described above, the USB stick contains several software, so you’ll have to install (you’ll just have
to unpack 3 archives) the following:
(1) ESL Server 
(2) ESL Client 
(3) Template Editor 
Server hardware: Pentium 4 (2 GHz or higher), 2 GB RAM
Java Runtime Environment Version 6, Update 36

imagotag Labels and license files
Please unpack the zip-archives ,  and  on your machine - e.g.
under C:\imagotag\.
: To unpack the zip-files you can either use the windows internal archive-unpacker (see
screenshots) or an unpack tool of your choice (e.g. the free tool 7zip – www.7zip.org).
Figure 4 - Unpack/Install imagotag Software #1
Figure 5 - Unpack/Install imagotag Software #2
After unpacking all 3 archives, your folder should look something like this:
Figure 6 - Unpacked imagotag software folder
That’s it, the imagotag software is now installed and you can step forward to point 2 - Start Server
and Client.
In order to start the ESL Service with the default configuration, just execute the jar file “server.jar” as
described in [Troubleshooting] 2 - Starting Java applications and wait for the small service GUI to
show up (if the window doesn’t show up after all, make sure your Java installation and configuration
is correct).
Figure 7 - ESL Service GUI
The service will listen to TCP connections on Port 8000 and 8001 and UDP
connections on Port 8000. Please make sure that there is no firewall issue
and/or interference with other systems.
After start of the service you can check the web-GUI of the server:
URL: http://:8000/
Login: admin/admin
During the first start the ESL Server will automatically create a Derby1 database. If another database
connection is needed or preferred, the connection parameters should be validated by imagotag.
: As you can see there are several level numbers, by default the server instance will start in level
3. You can find the description of the different levels in the Developer Reference (which is also
included on the USB stick) under “Integration Levels”.
For easier usage some example articles will be preloaded at the time you start the ESL Server. You
can find them here: C:\imagotag\server\data\fixtures\.
: The article records are based on the XML-standard.
Apache Derby, an Apache DB subproject, is an open source relational database implemented entirely in Java
Navigate to the unpacked client directory (see point 1.2 on how to unpack the software package) and
execute the “client.jar” file (see [Troubleshooting] point 2 on how to start a jar file).
Figure 8 - Starting ESL Client
The client is configured to connect to a server on the local machine per default. In order to change
this to a remote machine in a network you have to start the client with an additional parameter:
Windows
Create a shortcut/Edit existing short cut
Append “ --host hostnameOrIPAddress” at the end of the “Target” field. (
: The text to
append starts with an space and there are 2 hyphens to add!)
Linux
Append “ --host hostnameOrIPAddress” at the end of command (e.g. “java -jar client.jar -host 192.168.1.100”
: The text to append starts with an space and there are 2 hyphens
to add!)

Navigate to the unpacked template directory (see point 1.2 on how to unpack the software package)
and execute the “template.jar” file (see [Troubleshooting] point 2 on how to start a jar file).
Figure 11 - Starting the Template Editor
The AP-2010 by imagotag is the communication center in the store that transmits price information
to the labels. In order to ensure the communication between ESL server, access point AP-2010 and
the labels the access point has to be configured at the start of the ESL Server.
One way to configure the access point is on the client.
Figure 12 - ESL Client Access Point Configuration
Before labels are able to communication with the server at least one access point needs to be
configured. In standard configuration the AP-2010 should get an IP-address via DHCP
(recommended) and is accessible via web-GUI:
URL: http://
Login: admin/admin
: In this part of the Quick Start Guide it is assumed that a DHCP server is present
(you can find the steps to discover the access point without DHCP in the [Troubleshooting] section at
points 1.3 and 1.4).
Before you can configure the access point it’s necessary that the server will discover it.
The following points have to be observed:
Connect your machine to the same network as the AP
Plug in the power supply of the access point
During the boot process of the access point, start the ESL server software on the computer
(see point 2.1)
When the access point is booted up, the server will discovery it with an IP address (
The discovering process may take up to 2 minutes)
Use the ESL client to connect to your ESL server
Under System – Access Point Status – the AP should be listed as discovered (after successful
boot sequence)
One Column of the AP should show now the IP address
Now you’re able to configure the access point via web-GUI under http://
or a right click on the discovered AP –> Open in browser…
In the status overview you get some details about the AP-2010:
Figure 13 - AP-2010 Status overview
It’s recommended for the demo installation not to use the “Auto-Config” feature and configure the
AP manually.
The following actions need to be performed over the web-GUI
(1) Deactivate Auto-Config: Administration -> Auto-Config
(2) Set up network details (or leave DHCP): Administration -> Network
(3) Set up a wireless channel: Administration -> Wireless
The AP-2010 supports 11 wireless channels. It’s recommended to choose one of
the recommended channels: 3, 5, 8, 9 or 10. These channels do not interfere
with standard Wi-Fi channels 1, 6, 11 and are scanned by the labels more often
For further information about selecting channels see point 3.4.
After the configuration in the web-GUI it’s necessary to add this AP via the ESL Client: System ->
Access Point Configuration -> New …
Figure 14 - ESL Client AP configuration - System -> Access Pont Configuration -> New
Choose “Manual Configuration” if you don’t use Auto-Config and enter Access Point ID (AP ID) and IP
address (Host).
: After the basic configuration in the web-GUI, it is also possible to fill in AP-ID and AP-IPAddress automatically. For this choose "Create Configuration..." under System - Access Point Status Right click on the discovered and configured Access Point.
After saving the AP configuration you should see the AP under System -> Access Point Status as
ONLINE. In addition the AP status LED should turn
For a working installation a channel must be selected on each access point in the network. There are
11 non overlapping ESL channels reserved for the communication with the labels. Five of these
channels do not interfere with typical Wi-Fi installations and should therefore be favored. These are
the ESL channels 3, 5, 8, 9 and 10 and they should be selected if there is a Wi-Fi installation on the
Wi-Fi channels 1, 6 and 11.
Figure 15 - Visualization of used channels of the imagotag AP-2010
If there is a Wi-Fi installation operating at 2.4 GHz (IEEE 802.11b/g/n) or any other radio frequency
(RF) technology that uses the 2.4 GHz ISM band make sure to select the ESL channels that are least
overlapping with the existing installation. If there is no ESL channel without any overlapping both the
ESL and existing installation should still work but there might be a reduced overall speed in both
installations.
Warning: Do not select the same channel on two access points within one area. This will cause
interferences and avoids labels from joining the network. The same channel may only be selected on
two access points if it can be guaranteed that every label is within the range of only one of these
access points.
There are several LED colors that indicates the main status of the access point.

The security concept is based on individual registration codes for each label. Not only that the new
concept simplifies installations, it also provides stronger encryption and a secure key exchange with
individual communication key derived from a user defined network key.
Solid improved safety
Encrypted data type AES128 (Advanced Encryption Standard)
User defined 128 bit network key for each installation
Key is distributed to labels automatically
The new system requires a user defined 128 bit network key for each installation. The key is derived
from a passphrase that is defined by the customer and stored in the imago gateway and used by all
access points connected to that gateway to encrypt data communication to the labels.
A per-label communication key is transmitted to the labels during the registration of them. Each label
is assigned an individual registration code (it combines label ID and PIN code and it’s an
alphanumeric case-sensitive code with 11 characters).
The imago gateway will than automatically start the key exchange with the label secured by the PIN
extracted from the registration code.
First step is to set the parameter “encryptionPassphrase“ under System – Configuration (you can
choose the encryption Passphrase on your own).
Figure 16 - Set encryption key
: Do not change encryption passphrase if labels are already connected and encrypted (if you
want to change the encryption passphrase you’ll first have to unlock all labels – see
[Troubleshooting] point 1.8).
In order that labels can join the network it is necessary to register them first.
Via the ESL Client under File -> Register Labels it’s possible to register your labels manually with the
registration code shown on each single label or you could import a CSV file with your registration
codes. In order to refresh the entries press the refresh button shown in Figure 17.
: After the registration it could last a certain time until all registered labels are
joined to the network (from 30 minutes up to two hours, depending on configured access point
channels). After this you can send images to each label (see Start tagging).
Figure 17 - Add/Delete Label and refresh entries
All labels will arrive with its registration code shown on the display of the label. The code is printed as
a 2D QR code, as a 1D Code128 barcode and as human readable text. The registration process for the
customer is easy – he has only to scan one of this barcodes. The imago gateway will than
automatically start the key exchange with the label secured by the PIN extracted from the
registration code.

Here you can see the registration dialog in the ESL Client where one single label has been entered
with the registration code and the other one with the label ID (for old label versions < 3.0.0).
Figure 18 - Register labels dialog (registered with registration code and label ID)
: New versions of the imago gateway, client and access point (≥ 1.3.0) will also support old
labels that do not come with a pre-programmed PIN code. New labels (≥ 3.0.0) will also work in old
installations together with old labels but the gateway will not accept registration codes during the
registration process. To register the labels it is required to scan the barcode with the label ID from
the backside or the bottom edge of the label. As the gateway will not start the key exchange all data
is transmitted unencrypted to the labels.
It’s also possible to register labels with a commercial USB barcode scanner (2D/1D). You can also use
our iOS-App (for iPhone and iPod touch, only available on request).
Handheld terminals are mobile devices that are used to manage the ESL installation. If the handheld
provides a barcode scanner, it may be used easily to link articles and labels by scanning the article
barcode (usually EAN, UPC or GTIN) and the unique ID of the label.
Here you can see some screenshots of our iOS-App:

Here are the encryption status a label could have:
AES: Communication with label is encrypted with 128 bit AES
No PIN: Could not set encryption key as no PIN (registration code) was provided
Solution: Re-register label with registration code
Key unset: Communication is NOT yet encrypted
Solution: Set encryption key as described in section 4 - Set encryption key
Unsupported: Encryption is not supported by label firmware
Unknown: Security status is not determined yet
Figure 22 – Encryption status
If the label was registered and a communication key was set it will no longer work in other networks
using a different network key passphrase. To unlock this labels for other networks an unlock code is
required. The unlock code is similar to the registration code - it is a combination of the label ID and a
128 bit PUK code.
Via ESL Client select File – Unlock labels and enter the unlock key.
Figure 23 - Unlock Labels Dialog
: The unlock-code for the specific labels is enclosed in the Smart Box (in an envelope).
As soon as labels are online you can do several things:

family on page 5)
a. In the right pane, a priority (currently not relevant) could be set for the task, as well as the
Page to which the image should be sent and whether the image is preloaded.
b. When preloading, the image is placed in the memory of the label, but not yet displayed. The
image change will only be performed after the change to the relevant page. This allows for
each label that images are cached on the various pages and be accessed quickly by switching
to the relevant page.
By clicking on “open” the corresponding task(s) for the label(s) will be created and the transfer
begins.
Figure 24: Send image to label
For complete management of your articles select Articles – All Articles in the ESL Client. Here you’re
able to create/delete and edit your articles.
The Smart Box comes with 4 predefined articles which you can see here. You can add some more
demo articles, edit the existing ones or just step further to the next point Matchings.
Figure 25 - Article management
There’s also the possibility to import articles from a *.CSV-file.
For this, there are a few points to consider:
The CSV file should always be written with UTF-8 encoding.
Depending on the configuration in “../server/config/articles.config” the CSV to import should
look like this:
o articleNumber;gtin1,gtin2,gtin3..;name=;price=;field1=;field2
=;field3=;…
Where the last 3 fields (field1, field2, field3) are custom fields specified in the
“../server/config/articles.config” and every line the CSV file corresponds to one article.
Figure 26 - How the article.config looks like in the Smart Box installation
The article number field is mandatory, every other field is optional an can be left empty (e.g.
100000;;;;;;).
: If you add an article via ESL Client, price and name will be mandatory
The order of the first 2 fields articleNumber and gtin in the CSV file is essential. The order of
the other fields is not essential since they are identified by their fieldname (e.g.
name=, price=).
Figure 27 - Example for an article import CSV-file
Finally, to import the created CSV-file select Import – Import articles in your ESL Client.

A list of custom specified fields.
The logical link between an article and the label that shows the article information and price of this
article is called matching. With a matching the layout of the image rendered for the label is also
defined by specifying the name of a template.
In a more technical way a matching is the triple of:
Label ID
Article number or GTIN
Name of the template file
: Only one matching per label is allowed but a single article may be matched to more than one
label.
Select File – New matchings to open the dialog where you can select the desired data records and
create a number of matchings at the same time.
Figure 30 - New matchings dialog
Another way to create/edit matchings is under “Matchings – All Matchings”:
Select the desired data records (Label ID, Article Number) in the following window “New
Matching Record“ (either manually or with the magnifying glass symbol). Select an appropriate
template via “Template” that should be used to generate the image.
Confirm your choice by clicking Save. After that, the generated image is sent to the selected
label.
Figure 31: Create a matching
It’s also possible to create Matchings with ESL Client under Labels and Articles, for this just select the
desired article or label, right-click on it and select “New matching…” (the new matching dialog will be
pre-filled with the article or label information).
The template is used to specify the fields, which should be rendered into the image. The ESL Server
can handle multiple templates.
The image rendering process is based on XSL (EXtensible Stylesheet Language) templates. The
individual image for the label is then generated by applying the template to a XML, which is based on
the properties of the label and is expanded by a custom XML from the user.
The following steps are executed when processing a template:
Generating a record XML based on the label/task information and custom information provided
by the user
Applying the template (XSL) on the generated record XML. This results in a document containing
the fields, specified in this reference and values referenced from the XML

In order to use our rendering engine you must know our template language which is basically XSL.
We do also have a template editor with live preview, but you need a little bit time to setup
everything and get familiar with it. Therefore we suggest to send pre-rendered images to labels
(right-click on a label -> send image) which you can create with every image manipulation software
you want (e.g. Gimp, Photoshop, Paint, …). You can even take some pre-rendered images from us for
each label type with the correct resolution as a template – you’ll find some in the client’s directory
under data/images.
6.5.2.1
Open default template-file and load records from server:
Open the Template Editor by clicking the “template.jar” file located in the template-directory
(In our example it should be C:\imagotag\teamplate\).
Next step is to create a new template file or to open an existing one (The default.xsl template
file is located in the server-directory under C:\imagotag\server\data\template\).
To get a live preview you’ll have to load some records, in our case we load the demo article
records from our running server, see the following figure.
Figure 33 - Load Records from Server
After these steps your Template Editor window should look something like this:

Also you can find further information on the USB Stick under Documentation - Image Rendering
Reference.
The ESL server provides access to its interfaces methods through a RESTful web service API. The web
service is designed according to the “Representational State Transfer” (REST) architectural pattern.
The ESL server listens for incoming HTTP web service requests on the TCP port 8001 by default.
You can find further information about Webservice Integration on the USB Stick under
Documentation - Developer Reference.
We provide a CSV/XML plugin that is used for importing article information into the ESL Server.
You can find further information about Webservice Integration on the USB Stick under
Documentation – CSV/XML Import Plugin.
For custom integration we provide a Plugin-Interface. Software development service is available from
imagotag software development team or third-party integration partners.
For pricing get in touch with our sales agents (sales@imagotag.com).

Error while writing task to database
Task type not supported
Solution
The label is not licensed. Import the proper license file
for the label or check for typos in the label id.
The label may have been deleted or has never been
registered at all. Register label.
The size of the image does not match the label’s display
size. Please check the width and height of your image
and look up the display size in pixels for the label. These
sizes have to be equal.
Check template (wrong or faulty)
Change format of the image to standard format (e.g.
PNG or BMP)
Page not supported by label type, choose a different
page
Abort task or wait until unfinished tasks are finished
Check template directory for missing template file
Correct template file (Invalid content found)
Check server and article record configuration
The power status of the label is “Bad”, which means it is
very low on battery that in may not accomplish the
display update. Replace the battery of the label.
The server was not able to send the task to the Access
Point. Please make sure that the Access Point is not
offline (System -> Access Point Status) and there is an
established network connection between Access Point
and Server.
Check database connection
Upgrade AP software to process this kind of task
The ESL server may be started as a normal application, but on a productive system it is usually
required to have it automatically started without a user logged in. To achieve this the ESL server can
be registered as a Windows service. It is than started automatically without any graphics user
interface.
To install the ESL server as a Windows service the batch file install_service.bat is provided. If this file
is executed with administrator privileges (Right click – Run as Administrator) it will install the ESL
server installation from the same directory as a Windows service with the name ESL_SERVICE.
The file uninstall_service.bat will remove the Windows service if executed with administrator
privileges.
In order to prevent the example articles from being re-added to the server, remove the file
“server/data/fixtures/article.xml”.
You’ll also have to delete the demo articles shown in the Articles-section at the ESL Client.

Set a laptops Ethernet adapter to DHCP
Turn off all other network adapters (Wi-Fi)
Connect to the same network as the AP-2010 (use a common Ethernet cable to connect your
device directly with the AP-2010)
Start local ESL Server on laptop
Use the ESL client to connect to your local server
Under System – Access Point Status – the AP should be listed as discovered (after successful
boot sequence – may take up to 2 minutes)
o Press F5 on your keyboard or the refresh button in the ESL client to refresh the access point
status (the Client doesn’t refresh the status automatically!)
One Column of the AP should now show the IP address
Open a browser, type in http://:8080 or
o at the ESL client perform a right click on the discovered access point – Open in browser –
Maintenance – Status
: Restart your access point if discovering process takes more than 2 minutes.

You still got problems to find your AP in your network? There's another workaround: You can use
Apple's "Bonjour Print Services".
Download and install “Bonjour Print Services“ for Windows (pre-installed under OSX):
http://support.apple.com/kb/DL999
: After installation there’s no reboot required.
If the access point is connected directly to the system where the “Bonjour Service” is installed (or on
a network with running “Bonjour Service”) you can find the access point by typing the following in
the browser of your choice:
http://ap-.local:8080 (e.g. http://ap-12724.local:8080)
: You can reach older versions of the AP with http://imagotag-ap.local:8080 (custom hostnames
are only available on newer versions of the access point)
 Check the AP status
 Check AP configuration
o No Channel set
 Check network reachability of AP
 AP registered to Server?
 Reboot AP
After the registration it could last a certain time until all registered labels are joined to the network
(up to two hours, depending on number of access points and the channels used).
Warning: A label must not be registered to multiple ESL server installations at the same time. It will
only connect to one of this installations.
Check the encryption passphrase in Server Configuration (System – Configuration).
If label was already registered with a different passphrase you’ll have to unlock the label first in order
to register it on the server.
If the label was registered and a communication key was set it will no longer work in other networks
using a different network key passphrase. To unlock this labels for other networks an unlock code is
required.
Select File – Unlock labels and enter the unlock key.
The unlock-code for the specific labels is enclosed in the Smart Box (in an envelope).
If you have any further problems please contact the imagotag support (support@imagotag.com).
Before starting a Java application, make sure you have Java Runtime Environment Version 6 or higher
installed and you have set the necessary environment variables.
If the .jar file extension is known and associated with Java, just double-click the jar file to start the
application. Otherwise if the extension is not recognized:
Windows:
Create a shortcut of the jar file, right-click on it and open properties. Prepend “javaw.exe –jar“ to the
path in the “Target” field. Double-click the shortcut.
Linux:
Navigate via command line to the directory where the jar file lies and execute “java –jar
.jar”
In case your environment variables are not set properly (e.g. javaw.exe/java command could not be
found) do the following steps:
1. Locate your installation directory of your Java Runtime Environment
2. Set JAVA_HOME Variable
Under Windows:
- Right-click on “My Computer” and select “Properties”
- Click the advanced tab
- Click the “Environment Variables” button
- Under “System Variables”, click New.
- Enter the variable name as JAVA_HOME
- Enter the variable value as the installation directory of your Java Runtime Environment
- Click OK
- Look for the Path variable in “System Variables” and edit it
- Append a semicolon (;) and %JAVA_HOME%\bin to it
- Click OK
- Apply Changes
Under Linux:
- Use the “export” command to set your variables
- export JAVA_HOME=
- export PATH=$PATH:/bin
- In order to make these changes persistent, write them into your .bash_profile file and use
“source ~/.bash_profile” to apply the changes
