2. Solution overview
5 different solutions are currently supported by the ESL server application:
CSV-file solution. The CSV-file based solution operates by running the provided ESL
server application that monitors an input folder in which CSV-files, containing the product
and link databases, are being placed by a back office system. Logging is done in a SQLite
database file.
SQL solution. The SQL-based solution (MS-SQL, MySQL, Oracle, SQLite, PostgreSQL or
DB2) provides the possibility to monitor and control multiple stores using one central of
multiple local SQL databases in combination with the provided web application. The local
ESL server application monitors an SQL database using staging tables and processes
them and inserts status information of all ESLs into the SQL database. Optionally an ODBC
data source can be used to connect using a DSN of an SQL database.
CSV / SQL hybrid solution. Uses the provided ESL server application that monitors an
input folder in which CSV-files, containing the product and link databases, are being placed
by a back office system, but inserts status information of all ESLs into a local SQL
database to allow remote monitoring of the ESL system.
External content management solution. Allows the connecting of an existing content
management system to the ESL server. Pre-generated images are placed into an input
folder, which are automatically processed and send the corresponding ESLs. Logging of
status information can be done by SQL if desired.
SQL API. The ESL server supports a full SQL API, which can be used to create your own
(web) application by executing SQL queries to (remotely) control and monitor the ESL
system, while running the ESL server as background service.

2.1. CSV-file based solution
The CSV-file based solution operates by running the provided ESL server application that:
Monitors an input folder in which CSV-product databases are being placed by a back office
system and processes them (optionally with pre-processing by a middleware application).
Controls, monitors and configure ESLs and base stations
Allows manual editing of product and link data bases
Creates/changes image templates, generates the ESL images and sent them to the ESLs
Processes linking information from a handheld Wi-Fi barcode device or batch scanner
Stores log and status information into a local SQLite database file
A global overview of this solution is shown below. The following chapters will describe the different
parts of this system in more detail and how to get started.

Opticon ESL
ESL Server manual
v1.0.62.2
13
2.2. SQL Solution
The SQL-based solution provides the possibility to monitor and control multiple stores using one
central or multiple local SQL databases in combination with the provided web application.
The local ESL server application(s) will:
Monitor a local or central SQL database using staging tables and processes them.
Inserts status information of all ESLs into the SQL database
Controls, monitors and configures ESLs and base stations
Allows manual editing of product and link data bases (optional)
Creates/changes image templates, generates the ESL images and sent them to the ESLs
The web application can be added to provide remote and in-store control over the ESL system.
A global overview of this solution is shown below. The following chapters will describe the different
parts of this system in more detail and how to get started.

Opticon ESL
ESL Server manual
v1.0.62.2
14
2.3. CSV / SQL hybrid solution
The CSV / SQL hybrid solution matches the CSV-solution with as only difference that all status
information on the ESLs and base station are logged into a local SQL database which can be
retrieved by the back office system. See chapter 7.4 for more information.
2.4. External content management solution
When using external content management solution the back office or content management
system handles the generation of the images and the linking of products to ESLs.
The ESL server application basically only monitors an input folder for new images and distributes
them to the corresponding base stations / ESLs.
Status information will be logged into a local SQL database. See chapter 7.5 for more information.
2.5. SQL API
SQL can be used as API to create your own (web) application by executing SQL queries to
control and monitor the ESL system, while running the ESL server as background service.
See chapter 7.2 for information on how to use the SQL product and link staging tables to link and
update ESLs and use the status tables to monitor the ESL system.
See chapter 12 on how run the ESL server as service.
See Appendix I: Using the SQL API for more information on this API.
For maximum flexibility the SQL API can also be used in combination with the CSV/SQL hybrid
solution and with the external content management solution.

3. Setting up the hardware and software
This SDK contains the following pieces of hardware and software that will have to be installed in
order to get an ESL demonstration or pilot up and running:
The ESL Demo kit installer containing:
The ESL server application
The ESL Web application
Example database files and image templates
Firmware for the barcode terminal, base station and ESLs
Appload (optional)
USB drivers for the barcode terminal cradle (optional)
User manual
1 EBS30 / EBS40 Base station(s) that includes:
6V Power supply
Ethernet cable
6 EE201 2-inch e-paper ESLs (batteries included)
To be able to quickly link ESLs to products using barcodes, you can use the following options:
USB-HID barcode scanner (connected to the ESL server or by using the local web application)
OPH1004, H13, OPN2006 or OPH300x barcode terminal (incl. communication cradle/cable)
H21, H22 or H32 using Wifi (requires a local web server running the provided web application)
3.1. Installing the ESL Server application
To install and run the software you will also need a PC running Windows 7 or Windows XP (with
server pack 3) as server.
Before installing the software, make sure you have administrator rights and the PC is fully
updated with al Windows updates, including the latest Internet Explorer updates.
If your PC doesn’t have .NET Framework 3.5 (or higher) installed, you will have to install it prior
to installing the ESL Server application.
Run the SDK installer by starting the ‘setup.exe’ file.
Select the components that you wish to install. If you haven’t installed Appload or the Opticon
USB drivers on your PC before, make sure you install those components as well.
3.2. Installing and finding the EBS3x / EBS40 base stations
The base station can easily be installed by powering it up, connecting it to the Ethernet with
DHCP support and placing it within 10 meter (the actual maximum range is bigger) of your ESLs.
The PC will need to be connected to the same LAN, so it can communicate with the base
station*.

Opticon ESL
ESL Server manual
v1.0.62.2
16
After starting the application for the first time, no base station will be available to communicate
with ESLs.
Press the ‘Find’ button on the ‘Base stations-tab to find the connected base station.
Select the discovered base station to add and connect your PC to the base station.*
If activated ESLs are nearby, then the ESL count will start incrementing as they start connecting
to the base station. However if the ESLs are still ‘deactivated’, they will first have to be
reactivated.
* Note 1: when the base station is connected to the LAN with DHCP the IP address can vary
over time, making it necessary to remove the old base station entry by pressing the ‘Delete’-key
of your keyboard and discovering the base station again using the ‘find' button. Using static IP
leases in the DHCP server can resolve this problem.
* Note 2: when the base station is connected to the LAN without DHCP, the default IP
address/subnet mask of the base station is 169.254.19.63 / 255.255.0.0. Configure a PC or
laptop on the same subnet to change this using a web browser.
3.3. Installing and activating the ESLs
On arrival the ESLs already have their batteries inserted.
However, to allow safe transport by airplane, it is likely that the ESLs will show a
‘DEACTIVATED’ message in their left top corner. This means the ESLs do not emit any radio
signals and won’t be searching for base stations at this point.

Opticon ESL
ESL Server manual
v1.0.62.2
17
To reactivate these ESLs place them nearby the connected base station and select the base
station in the list view of the ‘Base stations’-tab. This allows you to press the ‘Reactivate ESLs’
button in the bottom right corner.
After pressing this button, a dialog will appear showing a progress bar and how many ESLs have
been reactivated so far.
Since the ESLs will only wake-up for a split second every few minutes, it can take more than 15
minutes before all ESLs have been successfully reactivated. You can verify this by checking
whether the ‘DEACTIVATED’ message has disappeared from the screen.
Active ESL’s will be periodically seek for an Opticon base station, so as soon as an Opticon
base station is within range, they will associate with it and start sending data requests and status
information to it. When a base station is turned off or an ESL is moved out of range, an ESL will
time out after a couple of minutes and starts seeking for another base station in range. See
chapter 6.1 for more information about configuring ESLs.
It might be possible that even though the ESLs are working properly, they still don’t connect to
the base station. This might be caused by strong interference on the default RF-channel of the
base station. To resolve this problem, see chapter 5.1
3.4. Mounting ESLs
Since there are many types of mounting clips to mount shelf labels to shelves, the ESLs of the
demo kit are supplied without mounting clips. Please contact Opticon for more information on the
mounting possibilities of our ESLs to your shelves. For simple demonstration purposes with
small amounts of labels one might also consider using double sided foam tape as a temporarily
solution.

4. Linking of ESLs to products
Linking of ESLs is the process of telling the system which product should be shown on which
ESL. This is usually done by scanning the MAC address bar code on the ESL label followed by
scanning (or entering) the unique ID of the product.
The unique ID can be anything: an EAN code, article number, location, room number, etc. As long
as it’s a unique identifier in the database, it can be linked to an ESL.
Opticon provides 3 methods for linking ESLs to products in your product database.
1. Using the ESL server application (manually or by using a USB-HID barcode scanner )
Advantage: Linking of ESLs in the ESL server application requires no additional hardware.
This makes it ideal for demonstration purposes and small installations.
Disadvantage:The ESL server usually isn’t located right next to the products and ESLs in a
store, which makes scanning both the ESLs and products and time consuming process
2. Using the provided web application (requires a handheld terminal with web browser & Wifi)
Advantage: Linking of ESLs using a web application is quick and can be done everywhere
in the store with almost all handheld barcode device (as long as it has a web browser and
Wifi). ESLs will immediately start updating after linking.
Disadvantage:Requires that the Web application is installed using an HTTP-server (like
Apache) and to be available on the Wifi network.
3. Using an Opticon batch terminal
Advantage: Linking using a batch terminal is quick and can be done everywhere in the
store and without any wireless connection.
Disadvantage: It requires an Opticon batch terminal, which needs to be moved back to the
ESL server to upload the created link information. ESLs won’t start updating until the batch
terminal is connected to the ESL server PC.
The following 3 chapters will describe these 3 methods in more detail.

4.1. Linking in the ESL server application
Linking in the ESL server application can be done manually and by using any USB-HID barcode
scanner.
Hint: Using a USB-HID barcode scanner is quick and avoids human error.
To (un)link an ESL, either select the ESLs-tab of the ESL-server and double click on an ESL that
needs to be (un)linked and then type, scan or find a product in the product database and then
press apply.
Or select the ‘Data’-tab and press the ‘Add’ button or double-click on an existing link and then
type, scan or find the MAC address of the ESL and the product ID.

When using an USB-HID scanner, this can be quickly done by scanning the MAC address bar
code on the ESL label followed by scanning the unique ID or barcode of the product.
4.2. Linking using an Opticon batch terminal
Opticon provide software for a wide variety of batch terminals to perform this task. The following
bar code terminals are currently supported:
OPN2002/5/6 (bar codes only; uses a mini USB cable)
OPH1004 (bar codes & keypad; requires a CRD1001 cradle)
H13 (bar codes & keypad; requires a CRD13 cradle)
OPL9728 (bar codes & keypad; requires a CRD9723RU cradle)
OPH3000 (bar codes & keypad; uses a mini USB cable)
More information on how to set-up the barcode terminal can be found in chapter 10.
4.3. Linking using the provided web application
Using Opticon’s H21, H22, H32 or any other Wifi terminal it is possible to link ESLs to products
and monitor the ESL system using a WiFi connection. This is done by installing a local web-server
that runs the provided web page to perform the linking.
For large installations this is the ideal solution, because it’s quick, can be done in the store, ESLs
will immediately start updating after linking and it contains multiple monitoring options to check the
status of all ESLs, products, base stations and the ESL server.
Using and setting up the web application is described in more detail in chapter 11.
