1 Introduction
LANCOM Wireless ePaper Displays provide a variety of options for displaying information. You can automatically and remotely update the calendar schedule for your conference rooms, you can create dynamic notices and direction signs, or you can control the price labels of goods on your shelves from a central location in real time. The wide range of different settings allows you to set up your very own customized use case.
The Wireless ePaper Displays are battery powered and radio controlled, so they operate independent of any external power supply or physical network connection. This allows a highly flexible use. The graphical display offers a high-contrast image with a very wide viewing angle, while at the same time consuming an extremely low level of energy. Data transmission is protected by 128-bit encryption.
The associated LANCOM E-series access points provide not only the wireless connection to the Wireless ePaper Displays: They also support a full WLAN infrastructure and also the iBeacon technology. By integrating all of these technologies into a single device, they all operate in parallel without interfering with one another.
This User Manual helps you with the steps required to commission the Wireless ePaper Server for centralized management and monitoring of your Wireless ePaper infrastructure.

1.1 How it works

The LANCOM Wireless ePaper solution consists of four components:
LANconfig allows the management and configuration of access points, includes the Wireless ePaper management
a
feature, and facilitates the configuration of the Wireless ePaper Server The Wireless ePaper Server creates the graphics and transmits the information to the access point
a
The access point connects to the Wireless ePaper Displays via radio
a
The Wireless ePaper Display shows the desired content
a
The software consists of LANconfig and the Wireless ePaper Server. LANconfig manages the access points, facilitates their configuration, and invokes the Wireless ePaper management. The Wireless ePaper Server receives the instructions from the Wireless ePaper Management, computes the content to be rendered, and transfers this to the access points. The access points forward the content to the Wireless ePaper Displays by radio.

Wireless ePaper Display
A Wireless ePaper Display is based on ePaper technology for the display of any information in the form of graphics and text. It can be used, for example, as room signage in the appropriate corporate design, or to display information about an article. The information on display is automatically updated via radio when the content changes, unlike any printed signs.

1 Introduction
LANCOM E-series access points
E-series access points communicate with Wireless ePaper Displays using radio frequencies in the 2.4-GHz ISM band and a proprietary protocol. They offer a choice of 11 radio channels.
Depending on the size of the area where the radio-controlled Wireless ePaper Displays are installed, more than one access point may be required to provide coverage over the entire area. If more than one access point is available, each Display automatically selects the access point with the best signal quality.
Further technical details on the LANCOM E-series access points can be taken from the data sheet.
LANCOM Wireless ePaper Server
The LANCOM Wireless ePaper Server is a software program required for the management of the LANCOM access points and Wireless ePaper Displays. The Wireless ePaper Server runs as a background service on an on-site Windows or Linux PC. It does not provide a graphical user interface.
The Wireless ePaper Server generates the graphics, which are transmitted to and shown on the Displays when there is a change of information.
LANconfig and Wireless ePaper management
The software LANconfig is required to operate the access points, with regard to both the WLAN and the Wireless ePaper solutions. Please use the appropriate User Manual for the installation and setup of LANconfig.
Monitoring and configuration of the Wireless ePaper infrastructure is available in LANconfig in the form of the Wireless ePaper management, which provides a graphical user interface. The Wireless ePaper management connects to the Wireless ePaper Server. The server can be installed on the same computer or on any other computer that is accessible on the network.

2 Installation and setup

2 Installation and setup
Before you can access a Display, you first need to install and set up the various components. Go to the LANCOM website and download the latest version of LANconfig and the current installation packages for the Wireless ePaper Server. The Wireless ePaper management is integrated into LANconfig, so no separate installation is required.
The necessary steps are explained below:
Install the Wireless ePaper Server software on a computer available locally in the network
a
Set up the license for the Wireless ePaper Server
a
Connect the access point to the local network and configure it
a
Register the Displays with the Wireless ePaper Server
a
The Wireless ePaper management indicates whether the Wireless ePaper Server, access point and LANconfig are communicating correctly. It is accessible in LANconfig under Tools > Start Wireless ePaper management. The Wireless ePaper management opens in a new window in the system's default browser.
The Wireless ePaper management is a part of LANconfig and does not require separate installation.

2.1 Installing the Wireless ePaper Server

Install the Wireless ePaper Server on a central computer in the network with constant access to the Wireless ePaper Displays.
Only one Wireless ePaper Server should be installed on a network, otherwise conflicts could arise.
5
However, in the interests of system latency, the Wireless ePaper Server and the E-series access points should be
5
connected over the same local network.
System requirements
The number of displays and their size directly affect the amount of RAM required. The required disk space may increase over time depending on the number of tasks and transmitted images.
Intel dual core processor or equivalent
a
2 GB RAM (512 MB for the server)
a
100 MB hard disk space for the server installation
a
Windows Vista or later, Windows Server 2003 or later, Linux (x86- and x64-architecture are supported)
a
Java Runtime Environment Version 7 or later (x86- and x64-JRE-versions are supported)
a
Installation
On computers with the Windows operating system, the software is installed with the supplied installation routine. This directly installs and starts the Wireless ePaper Server as a service. In principle, the software runs outside of Windows on any computer with Java. You will find the corresponding ".jar" files in the download area of the LANCOM website.

2 Installation and setup
To manage the Wireless ePaper Displays, the Wireless ePaper Server has to be started and running. To see whether the server is correctly installed and configured, look under the Wireless ePaper management for "Connected with server: [Server name] (IP: x.x.x.x)".
Files and folders of the Wireless ePaper Server installation:
Contains files used for the configuration of the Wireless ePaper Serverconfig/
Contains runtime data such as templatesdata/
Local mounted database (created when you first start)db/
External libraries required by your applicationlib/
Folder with user-specific pluginsplugins/
Database-related logging (created when you first start)derby.log
All logs of the import connections (created when you first start)import.log
Batch file for the installation of the server as a Windows serviceinstall_service.bat
Program code for operating the server on integration tier 1level1.jar
Required to run the Java application as a Windows serviceprunsrv.exe
Main executable file to launch the applicationserver.jar
All logs of the Wireless ePaper Server (created when you first start)server.log
Batch file for the installation of the server as a Windows serviceuninstall_service.bat
Updating the Wireless ePaper Server
In order to retain the database and configuration of your existing installation, simply copy the folder db and all modified files in the folders config and data to the new installation.
Starting the Wireless ePaper Server
You start the Wireless ePaper Server by double-clicking on the server.jar file. The Wireless ePaper Server requires a current Java Runtime Environment installed on the system. Furthermore, ".jar" files need to be associated with Java. When stated from the server.jar, the Wireless ePaper Server does not run as a service.
By default, this server uses TCP connections on port 8000 (for Wireless ePaper management requests) and 8001
5
(for web services) and UDP connections on port 8000 (for detecting access points). Make sure that these ports are not blocked by a firewall or used by other applications.
When starting for the first time, the Wireless ePaper Server automatically creates a local database.
It is not possible to start two instances of the Wireless ePaper Server at the same time on the same computer,
5
because the database is locked and the TCP port is busy with the other instance. Additional configuration work is necessary in order to run multiple installations on the same computer.
